A step-by-step guide to buying a condo (and the three steps most buyers skip)
I almost bought a building I couldn't insure. The unit was gorgeous. Vaulted ceilings, a corner balcony, a price that made me feel like I'd cracked the code. Then my lender called and used a phrase I'd never heard before: non-warrantable condo. Translation, delivered in a tone I still remember: the building had too many renters and not enough owner-occupants, so the loan wouldn't be backed on the secondary market. I could buy the condo. I just had to pay cash I didn't have.
That was the expensive lesson. Buying a condo is not buying a house with less yard. It is buying a share of a corporation that happens to include walls you can paint. The unit is the easy part. The building is where deals die—and where almost nobody looks until it's too late.
Key Takeaways
- Get pre-approved for a condo-specific loan, not a generic mortgage. The underwriting rules are different and stricter.
- The building must pass the lender's eligibility bar before your unit counts. Owner-occupancy ratios, HOA delinquency rates and commercial square footage all matter.
- Always read the HOA's reserve study and 12 to 24 months of meeting minutes before you make an offer. Special assessments hide in there.
- Your monthly budget must include HOA dues, a possible special assessment, and an HO-6 insurance policy—not just principal and interest.
- Condos and houses fail for different reasons. Know which risk you're actually signing up for.
- Your due diligence window is your escape hatch. Use it aggressively or lose it.
Why condo deals fail more often than house deals
A house is one transaction between you, a seller, and a lender. A condo is a transaction between you, a seller, a lender, and a corporation you don't control and didn't choose.
That fourth party is the reason roughly a third of the condo contracts I've watched fall apart had nothing wrong with the unit. The buyer loved it. The seller was reasonable. The building simply didn't qualify for financing.
The three parties that can kill your deal
- Your lender's underwriting desk, which applies a separate rulebook for condos
- The HOA, which can hold a right of first refusal, a rental cap, or a lawsuit you didn't know about
- The building's insurance carrier, whose master policy may leave gaps your HO-6 has to fill
None of these appear on a listing photo. That's the trap.
The actual step-by-step process
Step 1: Get a condo-specific pre-approval
Pre-approval for a house tells you what you can afford. Pre-approval for a condo tells you what you and the building can afford together.
Ask the loan officer one question directly: "Will you run this building through your condo questionnaire before I make an offer?" A lender who says yes is worth keeping. A lender who says "we'll figure that out later" is telling you where the risk lands.
Step 2: Screen the building before you fall in love
Here's the thing about the listing photos—they're designed to make you imagine your furniture in the space. Do the opposite. Look at the building's finances first, the unit second. It feels backwards. It saves months.
- What percentage of units are owner-occupied versus rented?
- How many owners are behind on HOA dues right now?
- What share of the building's square footage is commercial?
- Is there active litigation between the HOA and a developer, contractor, or insurer?
Any of these can disqualify a building from standard financing. And once a building is disqualified, its units become cash-only purchases, which shrinks the buyer pool, which softens prices. You are not just buying a home. You're buying into the resale liquidity of your own future sale.
Step 3: Read the HOA documents like a skeptic
This is where I've seen the most expensive mistakes. Not because buyers are lazy—because nobody tells them what to look for.
Ask for these, and ask in writing:
- The current budget and the last two years of financial statements. Is the HOA running a surplus or quietly borrowing from reserves?
- The reserve study. This is an engineer's estimate of what major repairs will cost and when. A reserve funded below roughly 30% is a warning sign.
- Meeting minutes from the last 12 to 24 months. Special assessments are almost always discussed in minutes long before they're voted on.
- The master insurance policy. What does it cover, and what's your HO-6 required to cover?
- The rules and regulations. Rental caps, pet limits, renovation restrictions, short-term rental bans.
- Any pending or threatened litigation.
I once read minutes that casually mentioned "roof consultant" in March, "roof bid" in June, and "assessment discussion" in September. The seller's disclosure said nothing about a roof. I passed. Eight months later the building voted through a five-figure-per-unit assessment.
Step 4: Make an offer with your conditions in writing
Your offer should be contingent on three things: financing that specifically names the building, a satisfactory review of HOA documents, and a professional inspection of the unit. Not the building—the unit. The building is the HOA's problem, which is exactly why you need to know how well they handle problems.
The document that flags most problems (and almost nobody reads)
The reserve study. It's boring. It's written by an engineer. It reads like a maintenance schedule because that's what it is.
And it is the single most predictive document in the entire purchase. If the HOA has deferred roof replacement for a decade and funded reserves at 15%, you are not buying a condo. You are buying a future invoice with a lobby attached.
What a healthy reserve study looks like
Funded at 70% or more, with a clear schedule of upcoming capital projects and no projects already past their target date. Anything lower, ask questions. Anything under 30%, assume you'll be asked to contribute.
Buying a condo versus buying a house
People frame this as a lifestyle choice. It's more accurately a risk-allocation choice. With a house, you control your maintenance and you absorb every surprise. With a condo, you outsource maintenance and you absorb a share of everyone else's surprises.
| Consideration | Condo | House |
|---|---|---|
| Monthly cost beyond mortgage | HOA dues, often rising 3–8% per year | Self-funded maintenance, irregular |
| Control over repairs | Shared, via the board | Entirely yours |
| Financing complexity | High—building must qualify | Low—unit stands alone |
| Risk of surprise cost | Special assessments | Roof, HVAC, foundation |
| Insurance | HO-6 plus master policy gaps | Single HO-3 policy |
| Resale pool | Shrinks if building loses eligibility | Broad |
Neither is better. They fail differently. A house fails when the furnace dies in January. A condo fails when the board votes on a new elevator in a meeting you didn't attend.
Red flags when buying a condo
Not every warning is obvious. These are the ones I've learned to treat as stop signs rather than speed bumps.
- Reserves funded below 30%. The building is one big repair away from a special assessment.
- High rental concentration. Too many investment units and the building may lose standard financing eligibility.
- Minutes that skip meetings. Missing minutes are often missing problems.
- An HOA that can't produce documents quickly. Slow document delivery now predicts slow governance later.
- Litigation involving structural or construction defects. Lenders hate these, and for good reason.
- Dues that haven't increased in years. Either the building is extraordinarily well run or someone is avoiding the math. It's usually the second.
- A board that discourages questions. You are about to become a shareholder in their corporation. Questions are your job.
How to buy a condo for the first time
If it's your first purchase, the biggest mistake is treating the process as a transaction rather than a vetting exercise. You are not just buying—you are joining.
Build your real monthly number first
Mortgage principal and interest plus HOA dues plus HO-6 insurance plus taxes. Add a maintenance buffer for whatever the HOA doesn't cover—typically in-unit plumbing, appliances and interior damage. A lender's affordability calculation will not include any of this. Yours must.
Get a buyer's agent who has closed condos
Not all agents know how to read HOA documents or how to interpret a reserve study. Ask directly: "How many condo transactions did you close in the last year?" The answer tells you whether you're hiring experience or enthusiasm.
Questions buyers ask me constantly
How long does the whole process take?
From pre-approval to closing, typically 45 to 90 days, with the HOA document review adding one to three weeks because boards move on their own schedule. If the building requires a formal condo questionnaire from the lender, add another week. Nobody controls that timeline except the management company.
Can I back out after the offer?
Yes, if you wrote contingencies into the contract. The document review and financing contingencies are your exit. If you waive them to make your offer more competitive, you've traded your safety net for a slightly better shot. That's a legitimate trade in some markets. Just make sure you know you're making it.
What if the HOA turns out to be badly run?
You have two options: pass, or buy knowing you'll need to get involved. I've seen buyers join the board within a year and turn a struggling building around. That's a real path. It's also a second job you didn't budget for.
The part most guides leave out
The condo you're buying has two prices. The one on the listing, and the one the building's finances will eventually charge you. The gap between them is invisible at the open house and obvious in the minutes.
Look at the building before the unit. Read the reserve study before the paint colors. Ask the management company questions that feel rude.
The best purchase I ever made involved a building with two red flags and a board honest enough to explain both. The worst almost-deal was a flawless unit inside a corporation that wouldn't answer the phone. The walls are the easy part. The corporation is the purchase.
