Buying a co-op or condo: read the building before you love the unit
With a house, you inspect the house. With a co-op or condo, the unit is the small half of the purchase. The building's finances decide your monthly bill, your ability to get a loan, and what the place is worth when you sell. Most buyers never see those numbers until their attorney does. This page tells you what gets asked, what the answers mean, and who actually verifies each one.

Co-op vs condo, the two minute version
A co-op means you buy shares in the corporation that owns the building, plus a proprietary lease on your unit. The board must approve you as a buyer, the monthly maintenance bundles the building's operating costs and usually its underlying mortgage and property taxes, and subletting is often restricted. Co-ops are usually the cheaper way into a given area, and the tradeoff is the board process and a narrower lender shelf.
A condo means you own real property with a deed, like a house. You pay common charges for the shared spaces plus your own property taxes. Financing is easier, renting the unit out is usually allowed, and prices run higher for the same square footage. The board reviews rather than approves in most condos, through a right of first refusal that is rarely exercised.
Maintenance vs common charges: what the monthly check actually covers
This is where buyers compare two listings and read the numbers wrong. A co-op's monthly maintenance and a condo's common charges are not the same animal, and the co-op number almost always LOOKS bigger because it carries things the condo owner pays separately. Here is what typically sits inside each check.
| What it covers | Co-op maintenance | Condo common charges |
|---|---|---|
| Your share of the property taxes | Usually inside the check. The corporation pays one tax bill for the whole building and your share rides in the maintenance. | Not included. The county bills you directly for your unit's taxes, on top of the common charges. |
| Heat and hot water | Often included, especially in older Long Island buildings with central systems. Confirm per building. | Usually your own bill. Most condo units have their own systems and their own utility accounts. |
| The building's underlying mortgage | Your share of the payment is inside the check when the corporation carries one. | Condo associations rarely carry a building wide mortgage; large projects are usually funded by assessment instead. |
| Staff and management | Included: super, porters, management fee. | Included: management, and staff where the community has any. |
| Building insurance | Included. The corporation insures the building; you insure your contents and interior with your own policy. | Included for common elements through the master policy; you insure the interior of your unit with your own policy. |
| Grounds, snow, common repairs, amenities | Included. | Included; this is most of what the charge is for. |
| Reserve fund contributions | Included, at whatever rate the board set. | Included, at whatever rate the board set. |
| Your own electric, internet, and your own mortgage | Yours, on top of the check. | Yours, on top of the check. |
The comparison rule. To compare a co-op listing against a condo listing fairly, add the condo's property taxes and its heat to the condo side first. A $1,400 co-op maintenance with taxes and heat inside can cost LESS per month than an $800 condo charge plus a separate $500 tax bill plus your own heating. Run the full monthly on both, the same way the affordability tool does it, or I will run it with you.
One more co-op wrinkle worth knowing. Because the maintenance carries your share of the building's property taxes and mortgage interest, a slice of it is treated differently at tax time, and the co-op issues shareholders a letter each year saying exactly how much. What that is worth in your return is your accountant's call, not mine and not the listing agent's.
And the word HOA. On Long Island people say HOA fee for all of these. Strictly, a condo bills common charges, a homeowners association community (where you own the house and the lot, and the association keeps the shared spaces) bills HOA dues, and a co-op bills maintenance. Three different animals wearing one nickname; the table above is the difference that matters.
Every building draws these lines its own way. The only authority on what a specific building's check covers is that building's own paperwork: ask the managing agent for the list in writing, and your attorney confirms it in the financials during due diligence.
The three things people actually get wrong
Ask around any buyer forum and the same three confusions come up over and over. Here they are, settled.
The building health questions
These are the questions I put to the managing agent and the listing side on every co-op and condo deal. None of them is rude. A building with good answers is proud of them.
The cheap maintenance trap
Buyers compare maintenance the way they compare rent: lower is better. Sometimes the opposite is true. Unusually low maintenance in an older building can mean the board has been deferring work for years, and the bill for that arrives later as an assessment or a maintenance spike, usually right after a new owner moves in.
The same logic runs through price. When two similar units in similar buildings sit far apart in price, the market has often already read the financials for you. The discount is real; it is just not free. The point is never to avoid those buildings. It is to buy them with your eyes open and price the coming work into your offer.
Who verifies what
Nobody expects you to audit a building. New York has a division of labor for this, and it works when every seat does its part.
Your attorney
Reads the financial statements, the offering plan and amendments, and the board minutes during due diligence, before your deposit is at risk. This review is the reason the questions above get real answers. In New York your attorney is not a formality; on a co-op or condo they are the inspection.
Your lender
Underwrites the building, not just you. Owner occupancy, reserves, arrears, litigation, and the sponsor's share all go through the lender's building review. A decline at this stage is information: the lender is telling you what it thinks of the building's finances.
Me
I get the documents and the answers before you fall in love with the unit: the questions above to the managing agent, the financials and minutes to your attorney, the building details to your lender early so the two approval problem surfaces in week one, not week six.
None of this page is legal or financial advice. It is the map of who gives you that advice, and when.
The board package, the part nobody warns you about
On a co-op, after your offer is accepted you assemble a board package: application, financial statement, tax returns, reference letters, and whatever else the building's form asks for. Then the board interviews you, and then the board decides. A co-op board can decline a buyer, and the process adds weeks to the timeline, so we build it into the plan from the start instead of discovering it under contract.
The package is also where preparation shows. A complete, clean package moves fast; a package with gaps sits on a board member's kitchen table for a month. I have seen both. We do the first kind.
Financing: the building picks the lender shelf
Here is the part that surprises people who have only bought houses: many lenders simply do not write co-op loans, and some condo buildings fall outside the standard approval lists that the big loan programs use. So the question is never bank versus anyone else. The question is which lenders actively lend on this building type, and ideally on this building. That is a shorter list than the internet suggests, and it is why the lender conversation on a co-op or condo starts with the building's details, not your paycheck.
Use any lender you like, and shop at least two, comparing APR rather than the teaser rate. The pre approval questions, how long a letter lasts, what refreshing it takes, what the credit pull does, live in the buyer guide's pre approval section. The lenders who pick up the phone for my clients are on the resources page.
