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.
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.
