How to sell a co-op in NYC: the steps from listing to closing

What you are actually selling

A co-op owner does not hold a deed to an apartment. According to the Attorney General's co-op page, a buyer purchases shares in a corporation. The shares are allocated to a specific apartment and carry a long-term proprietary lease, and maintenance is charged by the number of shares. That is why selling co-op shares works differently from an ordinary deed transfer.

It also explains the building's role. The same Attorney General material describes owners as both shareholders in and tenants of the same corporation, run by a board the shareholders elect. The Business Corporation Law is the main state law governing how most co-ops operate, and the by-laws and proprietary lease set the terms. If you are selling a co-op apartment, your stock certificate and proprietary lease are the core documents, and your attorney will want both early. If you have lost either, tell your attorney now.

For the buyer's side of the same transaction, see our guide to buying a co-op or condo in New York City.

Before you list: documents and decisions

Most delays in a co-op sale trace back to paperwork that was not ready. Before you pick an agent, gather what you can:

• Your stock certificate and proprietary lease
• The by-laws, house rules and any amendments, which set the building's sale rules
• Your latest maintenance statement and any assessment notices
• Your loan statements, if shares secure a loan, since the lender must be paid off or dealt with at closing
• A list of any alterations you made, and the board approvals you received for them
• Your purchase paperwork, which your CPA may need to figure the gain

Then make three decisions. Choose an attorney, since the sale is a legal transaction and the contract has building-specific terms. Ask the managing agent for the building's current process in writing. And decide how you will pick a listing agent. Introductions through this site go to agents on the operating team at eXp Realty, so that is one option, not a search of the whole market. Interview more than one agent if you want comparison.

Because you are likely buying again, read buy first or sell first before listing. In a board-approval sale, the timing of your purchase matters more than it does with a deeded house.

The managing agent and the board

The managing agent runs the building day to day for the corporation. In a sale, ask the managing agent how the building handles applications, fees and the paperwork that goes to the board. Treat the managing agent as a partner you need, not an obstacle. A request made early and politely tends to produce answers sooner.

A co-op sale is a contract subject to board approval. The board decides under the building's documents, and New York co-op boards are generally not required to give a reason for declining a buyer. That is not unlimited. The New York City Human Rights Law prohibits housing discrimination based on actual or perceived age and lawful source of income, among other characteristics. Board members can be liable.

New York City also adopted Local Law 58 of 2026, which sets deadlines for co-op boards to acknowledge and decide on applications submitted on or after July 28, 2026. One law firm summary describes the deadlines and the fines. Coverage details differ between summaries, so ask your attorney whether the law applies to your building.

The co-op board package for sellers

The board package is the application your buyer completes and submits. People often search for a "co-op board package for sellers", but the buyer assembles the personal and financial parts. Your job is to make the building-side parts easy and to get the buyer through it without surprises.

The practical seller steps look like this:

• Ask the managing agent for the current application and its list of requirements, and give it to your agent before the first showing
• Give buyers' agents the building's financial standards if the managing agent will share them, since they differ by building
• Provide the building documents the application asks the seller to supply
• Return signed seller forms quickly, because a package waits on them
• Ask what the building charges for processing and who pays it, and whether a move-in or move-out deposit applies
• Ask whether the board interviews buyers, and how and when it schedules them

Do not guess at financial requirements, and do not count on a building's standards matching another building's. Financial requirements, the flip tax and sublet rules are set by each building's own documents. A buyer who fits one building can fail another, so a clear picture of your building's standards, shared early, saves everyone a failed deal.

The flip tax and other seller charges

The best known charge is the flip tax. It is a transfer fee charged by the cooperative corporation on a sale of shares. It is not a government tax. State law, in Business Corporation Law section 501(c), allows fees payable on a sale or transfer of shares to vary. The amount and formula come from each building's offering plan, proprietary lease, by-laws or amendments. No fixed statewide rate exists. Read our flip tax guide for how to find and read yours.

Other charges you may meet, and amounts that vary by building, include:

• A co-op attorney fee, if the building's counsel reviews the sale
• A managing agent processing fee
• A move-out deposit
• A recognition agreement fee, which relates to the buyer's lender
• Maintenance adjustments for the closing date
• A bank payoff fee and a UCC-3 termination fee if a loan on the shares is paid off

Treat this as a list of questions for the managing agent, not a price list. These categories come from a New York law firm's description of NYC co-op seller costs, and no official page lists them or sets their amounts.

Plan the timeline around the board, not the listing

In a house sale, the clock runs from the signed contract to the closing, and the main variables are the buyer's loan and the title work. In a co-op sale there is one more gate. The buyer cannot close until the board approves, so the schedule depends on three things you do not fully control: how fast the buyer assembles an application, how fast the building reviews it and how fast the lender finishes.

You can shorten the parts you do control. Have your documents ready before the first showing. Return seller forms the day you receive them. Keep your managing agent contact current and your attorney informed of every date. If you are buying your next home at the same time, tell your attorney and your agent which closing has to come first, since a delay in a board decision can push the other deal.

Do not set a firm move-out date or sign a purchase contract that depends on your co-op closing until your attorney has read the sale contract's approval and closing provisions. A board decision can come back later than you hoped, and a rejected buyer sends the sale back to the market.

If the board turns your buyer down

It happens, and boards are generally not required to explain. Ask your agent and attorney to find out, through proper channels, whether the problem is fixable, such as a missing document, or final. Your contract should say what each side may do after a rejection, including whether the deposit is returned. Read that clause before you accept an offer, not after.

A rejection that appears tied to a protected characteristic is a different matter. Contact a New York attorney, and note that the New York City Commission on Human Rights takes discrimination complaints.

Transfer taxes and your net proceeds

Two government taxes come out of a typical New York City co-op sale on the seller's side. According to Tax Law section 1402, New York State charges $2 per $500, which is 0.4 percent, and the state form (TP-584 instructions) treats a residential cooperative apartment as residential real property. On New York City residential sales of $3,000,000 or more the state rate is 0.65 percent.

The city's real property transfer tax applies to co-op stock transfers too. For a co-op apartment it is 1 percent of the price at $500,000 or less and 1.425 percent over $500,000, applied to the whole price. The full rules, with examples, are in our NYC transfer tax guide.

Add your attorney, your agent's commission, which is negotiable and not set by law, and your loan payoff. The net proceeds guide and the net proceeds calculator put the numbers in one place. Add your building's flip tax and fees yourself, because only your documents have them.

Offer, contract and the sale of shares

Once you have an offer, your attorney prepares or reviews the contract. In downstate New York, the State Bar Association says the seller's attorney usually prepares it. Expect it to be conditioned on the board's approval and on the buyer's financing if the buyer has a loan. Your attorney should check who pays the flip tax and the building's fees under the contract, since the proprietary lease and the contract can allocate them differently.

Disclosure works differently for you than for a house seller. The state's Property Condition Disclosure Act excludes cooperatives from its definition of residential real property, as the statute text shows. See New York seller disclosures for what still applies and ask your attorney what your contract should say about your apartment's condition.

Brokers cannot give legal advice, according to the Department of State's Legal Memorandum LI04. Questions about contract terms belong to your attorney.

What happens at the closing

At the closing, shares and the proprietary lease change hands, your loan on the shares is paid off if you have one, building charges are settled and the transfer taxes are paid. Your attorney will tell you what documents you must sign and deliver. Typical items to clarify beforehand include the stock certificate, the lease assignment, any lender paperwork and the building's closing requirements, which differ by building.

The city return and payment are due within 30 days of the transfer, according to the city's tax page. Your attorney or title company normally handles filing. Ask them to confirm it in writing so no one is surprised later.

Tax on any gain is separate. Under IRC section 121, you can exclude up to $250,000 of gain, or $500,000 on a joint return, if you owned and used the home as your main home for at least two of the five years before the sale. See the IRS topic 701. A CPA can model the rest, including state and city income tax.

Moving out and what to do next

Coordinate the move with the building early, because buildings often have rules about elevators, hours and deposits. Our moving day guide covers what to ask. If you are clearing a home of many years, estate sale, consignment or donation helps you choose.

If you are deciding where to go next, the where to downsize page and our 55-plus communities list are good starting points, and Costs and Money covers the wider picture. The resources page lists official contacts. When you are ready for a conversation about selling, get matched. Introductions go to agents on the operating team at eXp Realty, so this is not a search of the whole market.
