Two buyers walk into two closings on the same afternoon. One bought a house: a roof, a furnace, a lot line, and a mortgage. The other bought a condominium unit and, without quite realising it, also bought a fractional share of an elevator, a parking deck, a boiler, a master insurance policy, a legal dispute with a contractor, and a reserve fund that is either healthy or is not. The first buyer’s risks are visible from the driveway. The second buyer’s risks live in a document package that most people skim in an evening.

This walkthrough runs the condo purchase step by step, and it concentrates on what actually changes versus buying a single family house rather than repeating the parts that are identical. The financing steps, the offer mechanics, and the closing sequence are covered in our first home walkthrough, and the mechanics of associations themselves in our note on HOAs. What follows is the condo specific layer: how dues reshape your budget, how to read a reserve study, what warrantability means and why it can block a loan, where the master policy stops and your own policy starts, and which building conditions quietly decide how easy your unit will be to sell.

Key takeaways

  • Dues sit inside your qualifying ratio, so they buy down your loan. On the illustrative purchase here, $420 a month of dues displaces roughly $66,000 of borrowing power at a 6.5 percent rate.
  • The reserve study is the most important document in the package. Percent funded tells you whether the next roof comes out of reserves or out of your bank account.
  • Your lender reviews the building, not just you. Investor concentration, delinquency, litigation, commercial space, and deferred maintenance can make a project ineligible for ordinary financing.
  • The master policy and your HO-6 policy meet somewhere, and the declaration decides where. Loss assessment coverage is the line that pays your share of a master policy deductible.
  • On the illustrative comparison used throughout, a $320,000 condo runs about $2,376 a month all in against about $2,973 for a comparable $415,000 house, a gap of roughly $597.

Why buying a condo is a different transaction

A house transaction has one balance sheet in it: yours. A condo transaction has two, and the second one belongs to a corporation you are about to join whether you read its books or not. Everything unusual about buying a condo flows from that fact.

The association owns and maintains the common elements, funds that work from dues and reserves, insures the structure under a master policy, and enforces a set of recorded rules that run with the land. You own the interior of a unit, a percentage interest in the common elements, and a vote. The percentage interest is not decoration: it is usually the formula that decides your share of dues and your share of any special assessment.

That structure creates three risks a house buyer never faces. The first is a shared repair bill you cannot control and cannot decline. The second is a financing risk that has nothing to do with your credit, since a lender can approve you and still refuse the building. The third is a rules risk, because the recorded documents can restrict pets, rentals, renovations, and even what you put on your own balcony.

None of that makes a condo a worse purchase. It makes it a different one, with a different due diligence stage. Run your own numbers through the affordability calculator before you tour anything, because the dues line changes the answer more than buyers expect.

Attached and closely spaced homes rather than a condominium tower, but the point holds: in shared ownership the building you can see from the street is only half of what you are buying.

What you actually own when you buy a condo

The legal answer is more interesting than it sounds, because it decides who pays for what. A condominium creates two categories of property. The unit is what the declaration says the unit is. The common elements are everything else, and they are owned by all owners together in undivided percentage shares.

Where the boundary sits varies from building to building. A common approach draws it at the unpainted interior surface of the perimeter walls, ceiling, and floor, which means the drywall face inward is yours and the studs, sheathing, and structure are the association’s. Another approach includes the drywall and finishes in the common elements. The declaration decides, and you cannot infer it from how the building looks.

There is usually a third category too: limited common elements, which are common property reserved for the exclusive use of one unit. Balconies, patios, assigned parking spaces, storage lockers, and the windows serving a single unit frequently fall here. The maintenance responsibility for limited common elements is a classic source of dispute, because some declarations assign it to the association, some to the owner, and some split maintenance from replacement.

Read the boundary language before you budget for anything. A buyer who assumes the association replaces windows, when the declaration assigns window replacement to the unit owner, has mispriced the purchase by thousands of dollars in the first cold snap.

Before you start: what you need in place

A condo purchase adds one whole stage to the process, and the stage is documentary rather than physical. Gather the following before you start touring, not after an offer is accepted.

  • Time budget. Plan on eight to ten weeks from accepted offer to keys, against roughly six to eight for a comparable house. The extra time is the association document package and the lender's project review.
  • Cash budget. Down payment, closing costs, and a separate cushion for a possible special assessment. On the illustrative purchase below the assessment scenario is about $13,000, roughly 4 percent of the unit price.
  • A lender who writes condo loans regularly. Not every loan officer handles project review often, and the ones who do will tell you in the first conversation which buildings in your market are already known to them.
  • A reading plan. The document package commonly runs to hundreds of pages. Know in advance which four documents you will read closely: the declaration, the bylaws and rules, the most recent reserve study, and the last twelve months of board meeting minutes.
  • Difficulty. Moderate. Nothing is technically hard. The difficulty is that the highest risk information arrives as a large PDF at the busiest moment of the transaction.

One more prerequisite is temperamental rather than practical. A condo purchase rewards buyers who are willing to walk away over a document, not over a house. The unit you toured will not change during your review window. The building’s finances might turn out to be exactly the reason you should not buy it.

Step 1: Set the budget around the dues, not the price

Start here because getting this wrong distorts every tour that follows. Lenders calculate your housing ratio from principal, interest, taxes, insurance, and association dues. The dues are not a lifestyle expense sitting outside the mortgage math. They are inside it, and they consume qualifying capacity dollar for dollar.

The mechanism is worth seeing as an amount rather than a principle. At an illustrative 6.5 percent over thirty years, each dollar of monthly payment supports roughly $158 of loan, because the payment factor works out near 0.00632 per dollar borrowed. Turn that around and $420 of monthly dues occupies the same space in your ratio as about $66,000 of mortgage. The dues did not raise your price. They lowered your ceiling.

That is why two listings can be misleading side by side. A $320,000 unit with $420 dues and a $340,000 unit with $600 dues look $20,000 apart. In qualifying terms, the higher dues consume roughly $28,000 more of your borrowing capacity than the lower ones, so the second unit is effectively further out of reach than the sticker suggests.

Watch out for the reverse error too. High dues are not automatically bad. A building whose dues include heat, water, and a properly funded reserve is charging you for costs a house owner also pays, just through a different door. Compare what the dues include before you compare their size, and put your own figures into the affordability calculator so the ceiling is a number rather than a feeling.

Step 2: Find out what the dues actually buy

Two buildings charging $420 can be delivering entirely different things, and the only way to know is to ask for the operating budget rather than the headline figure. The budget separates operating spending from the reserve contribution, and that split is the single most informative thing in it.

Operating spending is the recurring cost of running the property: insurance premiums for the master policy, water and sewer where the association is billed centrally, common area electricity, landscaping and snow removal, cleaning, trash, elevator service contracts, management fees, and administration. Reserve contribution is the money set aside for the components that fail on a multi year cycle: roof, elevators, boilers, paving, painting, plumbing risers, and windows where those are association property.

An association can make its dues look competitive by underfunding the reserve line. It is the easiest lever a board has and the most expensive one for owners. Low dues plus a thin reserve is not a saving, it is a deferred bill with your name on it.

Ask three questions of the budget. What share of dues goes to reserves. Which utilities are included and which you will pay separately. And has the board raised dues in each of the last three years, because an association that has held dues flat while costs rose is running down its cushion somewhere.

Step 3: Read the reserve study before you fall for the unit

The reserve study is the closest thing a condo has to an inspection report for the parts you cannot see. A professional inventories the major components, records their age and estimated remaining useful life, estimates replacement cost, and then models what the association needs to contribute monthly to have the money ready when each component reaches the end of its life.

The headline number is percent funded, which compares the reserve balance the association actually holds against the balance the study says it should hold at this point in the cycle. It is a ratio, not a dollar amount, which is what makes it comparable between buildings of different sizes. A high percentage means the next major project is already paid for. A low percentage means it is not, and the money will come from somewhere.

Read past the headline to the component table. A building that is 40 percent funded with a roof that has fifteen years of life left is in a different position from a building that is 40 percent funded with a roof that has two years left. Line up remaining useful life against the reserve balance and you can see roughly when the pressure arrives.

Then check the date of the study itself. Studies age badly, because construction costs move and components fail on their own schedule. Watch out for a package that contains a study from many years ago and no update: that is not a document problem, it is a governance signal.

Reserves are the difference between a planned roof replacement and a surprise bill. Percent funded is the number that tells you which one the building is heading for.

Step 4: Confirm the building is warrantable with your lender

This is the step with no equivalent in a house purchase, and it is the one that ends deals late. Your lender does not only underwrite you, it underwrites the project. A conventional loan is normally sold on after closing, and the buyers of those loans set eligibility rules for condominium projects. A project that meets them is described as warrantable.

The review looks at conditions you have no control over. How much of the building is owner occupied versus rented. Whether one owner or entity controls a large share of the units. What proportion of owners are more than a set period behind on dues. How much of the floor area is commercial. Whether the association is party to litigation, and if so what kind. Whether reserves and master insurance are adequate. And, increasingly, whether there is unresolved deferred maintenance or an outstanding structural repair recommendation.

The specific thresholds belong to the agencies, and they change. Do not plan around any number you read on a forum, including this one. Ask your loan officer to run the project early and tell you what the current standards are.

If a building fails, you are not necessarily out. Non warrantable condo lending exists through portfolio lenders who keep the loan on their own books, generally at a higher rate, with a larger down payment, or both. The practical consequence is that the pool of buyers for that building shrinks, which matters when you sell. Our pre-approval walkthrough covers what the lender is checking on your side of the file.

Step 5: Read the declaration, bylaws and rules for deal breakers

Three documents govern life in the building, and they sit in a hierarchy. The declaration is recorded against the land, defines the units and common elements, sets the percentage interests, and is the hardest to change. The bylaws govern the corporation: how the board is elected, how meetings and votes work, what powers the board has. The rules and regulations are the day to day layer, and the board can usually amend them without an owner vote, which is precisely why they deserve attention.

Read for the provisions that would change your decision. Pet restrictions by number, weight, or breed. Rental restrictions, including caps, minimum lease terms, and waiting lists. Renovation approval requirements, especially for flooring, plumbing, and anything touching a common element. Parking assignment and whether your space is deeded, assigned, or allocated at the board’s discretion. Move in procedures and elevator reservations. Restrictions on what may appear on balconies and in windows.

Then read the minutes, which is where the documents stop being theory. Board minutes for the last twelve months tell you what is actually breaking, what quotes have been solicited, whether dues increases are being discussed, and whether there is a dispute brewing with a contractor, an insurer, or an owner.

Watch out for the mismatch case: rules that are on the books but not enforced. Buying on the assumption that a written restriction will continue to be ignored is a bet on a board composition that can change at the next election.

Step 6: Price the master policy gap and quote your HO-6

Insurance is where condo buyers most often discover that a familiar word means something different. The association carries a master policy on the building. You carry an HO-6 unit owner policy. The two meet at a line drawn by the declaration, and if you do not know where that line is, you cannot know what to insure.

Master policies are commonly described in three broad shapes. Bare walls coverage stops at the structure and leaves interior finishes to the owner. Single entity coverage typically includes the original fixtures and finishes as built, but not owner improvements. All in coverage reaches furthest inward. These are descriptions rather than legal categories, and the actual wording of the policy and the declaration controls, so ask for both.

Your HO-6 then covers the remainder: interior finishes to the extent they are yours, personal property, personal liability, loss of use if the unit becomes uninhabitable, and loss assessment. That last one matters more than its obscurity suggests. If the master policy carries a large deductible and a covered loss occurs, the association can assess owners for their share of it, and loss assessment coverage is what responds.

On the illustrative purchase in this walkthrough an HO-6 runs about $45 a month, against roughly $149 a month for a homeowners policy on the comparable house. The saving is real, but it is not a free lunch: part of the building’s insurance cost is already inside your dues. Watch out for a master policy deductible large enough that your loss assessment limit would not cover your percentage share of it.

Step 7: Write the offer with a document review contingency

The offer itself looks familiar. Price, deposit, financing terms, closing date, and the standard protections covered in our note on contingencies and our offer walkthrough. What changes is that a condo offer should carry one additional protection and one additional instruction.

The protection is a review period for the association documents, with a right to terminate and recover your deposit if what you find is unacceptable. Many jurisdictions provide a statutory review right, and the length and the mechanics differ, so confirm what applies where you are buying rather than assuming. Where the statutory period is short, negotiate a contractual one that gives you enough time to actually read the package and ask questions.

The instruction is to order the documents immediately. The package usually comes from the management company, often for a fee, and it is not instant. A review clock that starts when documents are delivered is fine. A review clock that starts on acceptance while the package takes ten days to arrive is a trap.

Two more offer terms are worth thinking about. Ask who pays for any special assessment that has been adopted but not yet billed, because the default allocation is not always what a buyer would assume. And ask for a current statement from the association confirming the dues, the account status, and any assessments in progress, since that is the document your lender and your closing agent will both want.

Step 8: Inspect the unit and the building, then close

A condo inspection is narrower and wider at the same time. Narrower because the inspector’s access is limited to your unit and the accessible common areas. Wider because what you want to learn about is a whole building rather than one house.

Inside the unit, the checklist is close to the one in our inspection checklist: electrical panel and outlets, plumbing fixtures and visible supply and waste lines, the heating and cooling equipment serving the unit, appliances, windows and doors, moisture staining on ceilings and around windows, and the condition of finishes. Water staining on a ceiling in a stacked building is a message about the unit above, not only about yours.

Outside the unit, walk the common areas with the same attention. Look at the roof if you can get access, the condition of paving and walkways, the elevator’s service log if it is posted, the boiler or mechanical room, corridor finishes, and the garage deck, which is often the most expensive component in the whole property. Compare what you see against the reserve study’s component list. Agreement between them is reassuring. Disagreement is a question for the board.

Then close in the ordinary way, with two condo specific items on the closing statement: dues prorated to the day, and any adopted assessment allocated per the contract. Confirm both against the association’s statement before you sign, and see our closing costs breakdown for the rest of the line items.

Monthly cost of a condo and a house, line by line

The comparison most buyers want is monthly, and it is worth building explicitly rather than comparing prices. The illustrative case throughout this walkthrough is a $320,000 condo with $420 dues against a comparable $415,000 house, both financed at 20 percent down and an illustrative 6.5 percent over thirty years.

Monthly lines on an illustrative $320,000 condo and a comparable $415,000 house

Both at 20 percent down and an illustrative 6.5 percent rate. Bars scaled to the largest line. Illustrative figures, not typical costs.

House principal and interest$2,098
Condo principal and interest$1,618
Condo association dues$420
House property tax$380
House maintenance set aside$346
Condo property tax$293
House homeowners insurance$149
Condo HO-6 policy$45

Bars are scaled to the largest line, the house principal and interest of $2,098, so the condo principal and interest of $1,618 fills 77.1 percent of the track, the $420 of dues fills 20 percent, the $380 house tax fills 18.1 percent, the $346 maintenance set aside fills 16.5 percent, the $293 condo tax fills 14 percent, the $149 homeowners premium fills 7.1 percent, and the $45 HO-6 premium fills 2.1 percent. Taxes are shown at an illustrative 1.1 percent of price per year and the house maintenance set aside at an illustrative 1 percent of price per year. These are figures for one worked comparison, not typical costs.

Adding the four lines on each side gives about $2,376 a month for the condo against about $2,973 for the house, a gap of roughly $597. Two things in that comparison deserve scepticism. The maintenance set aside on the house side is a discipline, not a bill, and plenty of owners never fund it, which flatters the house until the day the roof goes. And the condo’s dues are a bill whether or not anything breaks, which is the trade: predictable cost in exchange for less control.

Where the monthly dues actually go

The $420 is not a fee, it is a budget, and seeing it split changes how you evaluate two buildings that charge the same amount.

An illustrative $420 monthly dues budget, by share

Illustrative allocation for one mid size association, summing to 100 percent.

Reserves 25.0% Grounds 21.9% Insurance 20.0% Admin 17.1% Utilities 16.0%
Reserve contribution, 25.0 percent: about $105 Grounds, cleaning and trash, 21.9 percent: about $92 Master insurance policy, 20.0 percent: about $84 Management and administration, 17.1 percent: about $72 Water, sewer and common utilities, 16.0 percent: about $67

Shares of the illustrative $420 monthly dues: $105 to reserves is 25 percent, $92 to grounds, cleaning and trash is 21.9 percent, $84 to the master insurance policy is 20 percent, $72 to management and administration is 17.1 percent, and $67 to water, sewer and common utilities is 16 percent. The reserve line is the one that decides whether the next major project arrives as a planned expense or a special assessment. Illustrative allocation for one association, not a survey.

Compare that allocation with a building charging the same $420 but sending only 8 percent to reserves. The second building is spending more on operations, or is simply underfunding its future, and its owners will meet the difference later. When you evaluate dues, evaluate the reserve share first and the total second.

Special assessments: the bill a house never sends

A house owner facing a $13,000 roof replacement chooses the timing, chooses the contractor, and can defer if money is tight. A condo owner facing the same work receives a bill decided by a vote they may have lost, on a schedule they did not set. That difference in control is the honest cost of shared ownership.

Special assessments arise from three common sources. A major component reaches the end of its life and reserves cannot cover it. An insured loss occurs and the master policy deductible has to be funded. Or a legal matter concludes in a way that costs money. The allocation almost always follows the percentage interests in the declaration, which is why your percentage interest is worth reading rather than skimming.

The illustrative scenario in this walkthrough is a $780,000 envelope and roof project across a 60 unit building. Spread by percentage interest, an average unit’s share is about $13,000, which is roughly 4 percent of the illustrative $320,000 unit price. Amortised mentally over ten years that is about $108 a month, which is a useful way to compare a low dues building with a thin reserve against a higher dues building with a healthy one.

Watch out for the payment plan framing. Boards often offer to spread an assessment over twenty four or thirty six months, sometimes with interest. That helps cash flow and does not reduce the amount. And an adopted but unbilled assessment is a negotiating item in your contract, not a surprise to discover after closing.

What lenders check on a condo that they never check on a house

It is worth setting out the project review as its own topic, because buyers consistently underestimate how much of it exists and how late it can surface. On a house, the property side of underwriting is essentially the appraisal, covered in our appraisal explainer. On a condo, the appraisal still happens and then a second review runs alongside it.

The lender collects a questionnaire completed by the association or its management company. The questions cluster into a few themes: ownership mix, financial health, insurance, litigation, and physical condition. Ownership mix asks how many units are owner occupied, how many are rented, and whether any single owner or entity controls a significant number. Financial health asks about the reserve contribution, the reserve balance, and how many owners are delinquent on dues. Insurance asks about the master policy limits, deductibles, and whether required coverages exist. Litigation asks whether the association is suing or being sued and over what.

Physical condition is the newer emphasis. Lenders increasingly ask whether the association is aware of deferred maintenance affecting safety, soundness, or habitability, and whether any inspection has recommended repairs that remain unfinished. An unresolved recommendation can put a project on hold for financing purposes regardless of how good your file is.

The practical instruction is simple. Tell your loan officer the building address as soon as you are serious about a unit, because some projects are already reviewed and some are already known to be problems. Finding out in week one costs nothing. Finding out in week seven costs the deal.

Condo, co-op, and townhouse: three different things

These three get used loosely and they are not interchangeable, which matters because the ownership structure changes the financing, the approval process, and the resale.

A condominium is real property ownership of a defined unit plus an undivided percentage of common elements. You get a deed to the unit, you get a normal mortgage secured by it, and the association governs the common property. This is the structure everything in this walkthrough describes.

A cooperative is different in kind. The corporation owns the building, and you own shares in the corporation plus a proprietary lease that entitles you to occupy a specific apartment. You are financing shares rather than real estate, which means a share loan rather than a conventional mortgage, and lenders for those are fewer. Co-op boards also commonly have approval rights over buyers, including interviews and financial disclosure well beyond what a lender requires, and in many co-ops the board can decline without giving reasons.

A townhouse is an architectural style, not an ownership form. A townhouse can be a fee simple house with its own lot that happens to share walls, or it can be a condominium unit, or it can be a fee simple house inside a homeowners association. Only the deed and the declaration tell you which. Ask, early, because a buyer comparing a townhouse to a condo may be comparing two identical looking properties with different documents behind them.

FHA and VA approval and why it changes your buyer pool

Government backed loans add another approval layer that operates at the project level. Both the FHA and the VA maintain lists of condominium projects approved for their programmes, and a unit in an unapproved project generally cannot be financed with those loans, with limited exceptions such as single unit approval processes.

The important consequence is not really about your own financing, unless you are using one of those programmes. It is about demand. Approval widens the pool of buyers who can purchase in the building, and losing approval narrows it. Approvals also expire and require the association to recertify, and some boards simply let them lapse because nobody pushed for renewal.

So the question to ask is a two part one. Is this project currently approved, and if it is not, was it ever. A building that has never sought approval is in a different position from one that let an approval lapse while its finances deteriorated. Our explainers on FHA loans and VA loans cover the borrower side requirements; the project side is separate and is checked separately.

Confirm current status through the official programme lookups rather than a listing remark. Approval status changes, listing copy does not get updated, and a buyer who relies on the listing can lose weeks.

Rental caps and investor concentration

Rental restrictions cut two ways, and buyers usually think about only one of them. If you might ever rent the unit out, the cap is your constraint: many declarations limit the number or percentage of units that may be leased, impose minimum lease terms, or require a waiting list. If the cap is reached when your circumstances change, you cannot rent, which turns a flexible asset into an inflexible one.

The other direction matters even if you never intend to rent. High investor concentration is one of the conditions lenders examine, and a building that drifts past the thresholds can become harder to finance conventionally. That shrinks the buyer pool for every owner in the building, including the ones who live there.

A cap that is well below the current rental level is therefore a stabiliser, and a building with no cap at all is worth a closer look at the current mix. Ask the management company for the current owner occupancy percentage in writing rather than relying on impressions from a tour.

Watch out for short term rental questions specifically. Many associations have added or tightened restrictions on stays below a set number of days, and the enforcement provisions can include fines that escalate. If a listing markets a unit as suitable for short stays, verify that claim against the rules and the recent minutes, not against the listing.

What makes one condo harder to resell than another

Resale risk in a condo attaches to the building far more than to the unit, which is counterintuitive for buyers used to houses. A renovated kitchen improves your unit. It does not improve the reserve balance, the dues trajectory, or the litigation docket.

Five building conditions do most of the damage. Dues rising faster than the local market, because buyers price the payment and not the sticker. Visibly underfunded reserves, which sophisticated buyers and their lenders both notice. A recent or pending special assessment, which turns your listing into a negotiation about who pays it. Active litigation, which can make conventional financing unavailable while it is unresolved. And loss of programme approval or drift past investor concentration thresholds, both of which cut the number of people who can buy.

The mirror image is also true, and it is the reason to do the document work properly. A building with healthy reserves, a documented maintenance plan, stable dues, and no litigation is easier to sell into than the equivalent house, because the buyer can verify its condition from paperwork rather than guesswork.

There is one more resale factor with no house equivalent: how many units in the building are for sale at once. A large building with a dozen near identical units listed simultaneously is a market where your unit competes with itself. Check the current listing count before you buy, and see our new construction comparison for the same dynamic in a development phase.

A worked example from first tour to closing day

Run the whole thing through once with numbers attached. Every figure below is illustrative and chosen to keep one example consistent.

The buyer tours a $320,000 two bedroom unit with $420 monthly dues. At 20 percent down that is $64,000, leaving a $256,000 loan. At an illustrative 6.5 percent over thirty years the principal and interest works out to about $1,618. Property tax at an illustrative 1.1 percent of price is about $293 a month, and an HO-6 policy at an illustrative 0.17 percent of price per year is about $45. Adding the dues, the all in monthly cost is about $2,376.

The comparable house is $415,000. Twenty percent down is $83,000, leaving $332,000 and a payment of about $2,098. Tax at the same 1.1 percent is about $380, homeowners insurance at an illustrative 0.43 percent of price per year is about $149, and a maintenance set aside at 1 percent of price per year is about $346. That totals about $2,973, so the condo runs roughly $597 a month less and needs about $21,850 less cash at closing once closing costs at an illustrative 3 percent are added to each side.

Then the buyer does the document work. The reserve study shows the association 40 percent funded with a roof and envelope project estimated at $780,000 and roughly four years of remaining life on the roof. Spread across the 60 units, an average share is about $13,000. The buyer treats that as a near certainty rather than a risk, mentally adds about $108 a month to the condo’s cost over ten years, and finds the comparison still favours the condo by roughly $489 a month.

The decision, though, does not turn on the $489. It turns on whether the buyer has $13,000 available when the board votes. That is the real question a condo purchase asks, and the companion beside this walkthrough reprices all of it for your own numbers.

Common mistakes condo buyers make

  • Comparing prices instead of payments. Dues sit inside the qualifying ratio, so a cheaper unit with higher dues can be the more expensive purchase and the harder one to qualify for.
  • Treating low dues as good news. Dues below the local norm frequently mean an underfunded reserve, which converts into an assessment later. Look at the reserve share of the budget before the total.
  • Skimming the document package. The highest risk information in the entire transaction arrives as a large PDF at the busiest moment. Read the declaration, the reserve study, and twelve months of minutes properly, or pay someone to.
  • Assuming the master policy covers the interior. It might, partly, or not at all. The declaration and the policy wording decide, and the gap between them is what your HO-6 is for.
  • Finding out about warrantability late. A lender can approve you and decline the building. Give the loan officer the address in week one.
  • Ignoring the rules you do not currently care about. Rental caps, pet limits, and renovation approvals become expensive exactly when your circumstances change, which is the moment you cannot renegotiate them.

Troubleshooting the situations that come up

What if the association will not release documents quickly. This is common and it is usually a management company throughput problem rather than obstruction. Order on day one, escalate through your agent to the management company directly, and if delivery slips, ask for a written extension of the review period rather than accepting a compressed read.

What if the reserve study is old or missing. Treat both as material facts rather than administrative gaps. Ask the board when the last study was performed and whether one is scheduled. In the absence of a study, the operating budget’s reserve contribution and the age of the major components are the best available proxies, and both should push you toward caution.

What if the building fails warrantability. Ask your loan officer exactly which condition failed, because some are curable and some are structural. A delinquency percentage can improve within months. A commercial space share cannot. Then decide whether a portfolio loan at higher cost is worth it, remembering that the same constraint will face your eventual buyer.

What if a special assessment is announced during your contract. Read the contract’s allocation language, then negotiate. Common outcomes include the seller paying it in full at closing, a price reduction of the assessed amount, or a credit. What you should not do is proceed without addressing it and assume the outgoing owner will settle it.

What if you love the unit but the finances worry you. That is the situation this whole review exists to surface, and the honest answer is that a great unit in a weak building is still a weak purchase. Compare it against renting for another year using our rent versus buy math before you decide the unit is irreplaceable.

The condo buying checklist

  • Run the dues into the affordability calculation before touring, not after.
  • Ask for the operating budget and check the reserve share, not just the dues total.
  • Give the building address to your loan officer as soon as you are serious about a unit.
  • Order the association document package on the day the offer is accepted.
  • Read the declaration for the unit boundary and the percentage interest.
  • Read the most recent reserve study, including the component table and the study date.
  • Read twelve months of board meeting minutes for repairs, quotes, disputes, and dues discussions.
  • Check rental caps, pet rules, renovation approvals, and parking allocation against how you actually live.
  • Get the master policy declarations page, note the deductible, and quote an HO-6 with loss assessment coverage.
  • Ask in writing whether any assessment has been adopted, discussed, or is anticipated.
  • Ask for the current owner occupancy percentage and the number of units currently listed for sale.
  • Confirm programme approval status through the official lookups rather than the listing remarks.
  • Inspect the unit, then walk the common areas and compare what you see with the reserve study.
  • Verify prorated dues and any assessment allocation on the closing statement before signing.

The bottom line

Buying a condo is the ordinary purchase process plus one extra stage, and the extra stage is where the money is. Your unit is the part you can see, tour, and inspect. The building is the part that decides your monthly cost, your financing, and how easily you sell, and it is disclosed to you as paperwork rather than as a property.

On the illustrative comparison carried through this walkthrough, the $320,000 condo runs about $2,376 a month against about $2,973 for the comparable $415,000 house, and it needs roughly $21,850 less cash at closing. That gap is real and it is a genuine reason condos work for a lot of buyers. It is also fragile, because a $13,000 special assessment on a 40 percent funded building takes back a decade of it.

So do the three things that a house buyer never has to do. Put the dues inside your budget rather than beside it. Read the reserve study, the declaration, and the minutes as carefully as you would read an inspection report. And give your lender the building address early enough that a project problem is a decision rather than a disaster. Everything else about buying a condo is just buying a home.


Read this walkthrough as a planning document for a condominium purchase, not as real estate, lending, insurance, tax, or legal advice. The $320,000 unit, the $415,000 comparison house, the $420 of monthly dues, the 6.5 percent rate, the 20 percent down payments, the tax and insurance percentages, the $780,000 project, and the resulting $13,000 illustrative assessment were constructed so that a single example could be followed from tour to closing, and none of them is a prediction of what any particular building will charge or cost. Condominium law, statutory document review rights, association powers, insurance policy scope, and lender project eligibility rules all differ by jurisdiction and by programme and change over time, so nothing here states what is permitted or required where you are buying. Confirm the declaration boundary and any assessment with the association, the loan eligibility with a licensed mortgage professional, the coverage split with a licensed insurance agent, and the contract terms with a real estate attorney before you sign anything or send funds.

Frequently asked questions

What is the biggest difference between buying a condo and buying a house?

The building is part of the purchase, and you are buying into a shared balance sheet you did not create. A house purchase is a decision about one property and one set of systems. A condo purchase is a decision about your unit plus a share of a roof, an elevator, a parking structure, a boiler, an insurance policy, and a reserve fund, all managed by people you have not met and funded by neighbours who may or may not pay on time. That is why a condo purchase adds a whole document review stage that a house purchase has no equivalent for, and why two condos with identical floor plans and identical asking prices can carry very different risk.

Do HOA dues really reduce how much house you can afford?

Yes, and by more than most buyers expect, because lenders count dues inside your housing ratio exactly the same way they count principal, interest, taxes, and insurance. On the illustrative purchase used throughout this walkthrough, dues of $420 a month at a 6.5 percent rate displace roughly $66,000 of loan, because that is the loan amount whose monthly principal and interest would be $420. If you tour a $340,000 condo with $600 dues and a $320,000 condo with $420 dues, the qualifying gap between them is considerably wider than the $20,000 price gap suggests. Always run the dues into your budget before you fall in love with a floor plan.

What is a reserve study and why does it matter so much?

A reserve study is an engineering and financial report that lists the association's major components, estimates how many years of useful life each has left, estimates what each will cost to replace, and calculates what the association should be setting aside every month to be ready. The important number it produces is percent funded, which compares the reserve balance the association actually holds against the balance the study says it should hold. A well funded association absorbs a roof replacement out of reserves. A poorly funded one sends every owner a special assessment. Ask for the most recent study, and ask when it was last updated, since a study that is many years old is describing a building that no longer exists.

What does a special assessment cost and can I avoid one?

A special assessment is a one time charge levied on owners when the association needs money it does not have, usually for a major repair, an insurance deductible, or a legal settlement. There is no standard amount because it depends entirely on the project and how the cost is allocated. On the illustrative building in this walkthrough, a $780,000 envelope and roof project across 60 units works out to about $13,000 for an average unit, which is roughly 4 percent of the illustrative $320,000 unit price. You cannot vote your way out of one once it is properly adopted, which is exactly why reserve funding and the age of the building's major components deserve so much attention before you make an offer.

What is a warrantable condo and why do lenders care?

Warrantable is shorthand for a project that meets the eligibility rules of the agencies that buy conventional mortgages, which is what allows a lender to sell your loan on the secondary market at ordinary pricing. The review looks at things that have nothing to do with your unit: how many units are owner occupied versus rented, whether one owner or entity controls a large share of the building, what percentage of owners are behind on dues, how much commercial space the project contains, whether the association is in litigation, whether reserves and insurance are adequate, and whether there is unresolved deferred maintenance. The specific thresholds are set by the agencies and change over time, so confirm the current rules with your lender rather than relying on any figure you read online.

Do I still need my own insurance if the building has a master policy?

Almost always yes, and the policy you need is different from a standard homeowners policy. The master policy covers the building structure and common areas, and how far inward it reaches depends on the declaration, with bare walls, single entity, and all in coverage being common descriptions of very different scopes. An HO-6 unit owner policy covers what the master policy does not reach: your interior finishes if the declaration leaves them to you, your personal property, your liability, loss of use, and importantly loss assessment coverage for your share of a master policy deductible. On the illustrative purchase here an HO-6 runs about $45 a month, but the right amount of interior coverage is determined by reading the declaration, not by a rule of thumb.

Are condos harder to sell than houses?

Some are, and the reasons are usually specific rather than general. A condo becomes harder to sell when its dues have risen faster than the local market, when its reserves are visibly underfunded, when it has just levied or is about to levy a special assessment, when it is in litigation, when it has lost agency or government agency approval so that fewer buyers can finance it, or when it has hit an investor concentration level that scares lenders. Notice that every one of those is a building condition, not a unit condition, so a beautifully renovated unit inherits its building's resale problem. That is the strongest reason to read the association documents as carefully as you read the inspection report.

How long does buying a condo take compared with buying a house?

Plan on a similar overall timeline with one extra stage inserted, so if a house purchase runs about six to eight weeks from accepted offer to keys, a condo purchase often runs eight to ten. The extra time comes from the association document package, which has to be ordered from the management company, delivered to you, and read inside a contractual review window, and from the lender's project review, which can raise questions that take days to resolve. Ordering the documents on day one rather than day ten is the single easiest way to protect the timeline. Ask your agent to request the package the moment the offer is accepted.
