NYC Condo & Co-op Seller’s Guide
The Process

From listing to proceeds, the full picture

A NYC sale has more moving parts than most sellers expect. Knowing the sequence upfront helps you make better decisions at each stage, from how you price to which buyer you accept.

01
Prepare to List
2 to 4 weeks before
Declutter, stage, and photograph. Pull your proprietary lease or offering plan now. Confirm the flip tax amount, sublet history, and any financing restrictions. These details shape your buyer pool and should inform your asking price.
02
Go Live
Day 1
Your unit hits StreetEasy, MLS, and your agent’s network. Pricing correctly at launch gives you the best chance of a strong offer early, when buyer interest is highest.
03
Offer and Negotiation
Week 1 to 6
Offers arrive and your agent negotiates price, contingencies, and closing date. For co-op sellers, your agent also reviews the buyer’s financial profile at this stage, helping you choose a buyer the board is likely to approve.
04
Contract Signed
Week 2 to 8
Attorneys finalize the contract of sale. The buyer wires a 10% deposit into escrow.
05
Board Package
Week 4 to 10 (co-op and condop only)
Your buyer assembles 20 or more documents and submits them to the managing agent. Under the 2026 NYC law, boards must acknowledge receipt within 15 days and issue a decision within 45 days of a complete submission.
06
Board Decision
Week 8 to 14 (co-op and condop only)
The board approves, requests an interview, or declines. A strong buyer with the right financial profile has a good approval rate. Thorough vetting at the offer stage gives your deal the best chance of moving smoothly through this step.
07
Closing and Proceeds
Week 10 to 18
Final walkthrough, then closing at your attorney’s office or by remote signing. Proceeds wire the same day. Flip tax, transfer taxes, attorney fees, and commission are all settled here. What remains is your net.

on a $1.5M sale
~$120,000–$165,000 ~$105,000–$125,000 ~$105,000–$120,000

Figures based on a $1.5M sale. Broker commission is the largest variable, negotiable based on market conditions and property. Co-op sellers should confirm their exact flip tax amount in the proprietary lease before pricing; it directly affects net proceeds and is often higher than expected. Transfer taxes are typically seller costs but can be negotiated at times.

Confirm your flip tax before you set your asking price

Co-op flip taxes are set by the building and vary widely. Some charge 1% of the sale price. Others charge a percentage of profit. Some charge a flat fee per share. Checking the transfer of shares section of your proprietary lease before you list gives you an accurate net figure and puts you in a stronger position from the start.

Know What You Are Selling

Your property type determines who can buy it and how long it takes

Co-op, condop, and condo each come with a different buyer pool, timeline, and cost structure. Understanding the differences helps you set the right price and choose the right buyer.

Pied-à-terre buyersLimited; boards often restrictGenerally allowedAllowed, but new annual tax applies

* A condop is legally a co-op but operates with condo-like rules, typically due to a commercial ground-floor unit. Condop sellers generally have a wider buyer pool and fewer restrictions than standard co-ops.

New: Pied-à-terre tax, effective July 1, 2026

A new annual surcharge applies to NYC co-ops, condops, and condos that are not the owner’s primary residence. Phase 1 rates (2026 to 2028): 4% per year on units with a DOF assessed value of $1M to $3M; 5.25% on $3M to $5M; 6.5% on $5M or more. If your likely buyers are primary residents, this does not affect them. If your unit may attract second-home purchasers or investors, understanding this cost helps you position the listing and price for that audience.

Know the Room

Everyone at the table has their own interests

Each party has a specific role and their own interests. Knowing who is in the room and what they are focused on helps you follow the process with confidence.

Seller That’s you Your Agent Prices, markets, negotiates Your Attorney Negotiates contract; handles closing Buyer’s Agent Represents buyer’s interests Co-op Board Approves or rejects your buyer Managing Agent Collects & reviews buyer’s package Buyer’s Lender Finances the purchase
Your Agent
Sets pricing strategy, markets the property, and qualifies buyers before you accept an offer. The difference between a good and average agent shows most in how they handle multiple offers and buyer vetting.
Your Attorney
Negotiates the contract of sale, reviews the buyer’s proposed changes, coordinates with the board and managing agent, and handles the closing. Use a residential real estate specialist.
Buyer’s Agent
Represents the buyer, not you. They are a useful communication channel. All substantive terms flow through attorneys.
Co-op Board
Volunteer residents who approve or reject your buyer. You have no say in their decision. Under the 2026 NYC law, they must decide within 45 days of a complete package submission. A rejection terminates the deal and sends you back to market.
Managing Agent
The building’s property manager. They receive and review the buyer’s board package, confirm it is complete, and submit it to the board. They also collect your move-out deposit and coordinate scheduling.
Buyer’s Lender
Finances your buyer’s purchase. A slow lender is one of the most common reasons closings are delayed. Your agent should ask about financing status before you accept any offer.
Common Questions

What sellers ask most

Straightforward answers to the questions that come up in every listing conversation.

How do I price it correctly?+
Start with recent closed sales in your building and neighborhood. For co-ops, pricing typically runs 10 to 20% below comparable condos. The buyer pool is smaller and the process takes longer, and well-informed buyers price that in. Your agent should walk you through a full comp analysis before you go live.
What does the co-op board look at when reviewing my buyer?+
Boards review a buyer’s complete financial picture: income, assets, debt-to-income ratio, post-closing liquidity, employment history, and personal and professional references. They also consider how the buyer plans to use the unit and whether that aligns with building rules. Boards can approve or decline without providing a reason, within fair housing law. The good news is that buyers who meet the building’s financial profile and come with a well-prepared package have a strong approval rate. Knowing your building’s standards before you accept an offer helps you choose a buyer who is a good fit.
What happens if the board does not approve my buyer?+
The contract terminates and the buyer’s 10% deposit is returned. Most sellers in this situation return to market and find a new buyer. The best way to avoid this is to work with an agent who reviews a buyer’s income, debt-to-income ratio, post-closing liquidity, and employment history before you accept the offer. An agent who knows your building’s approval history can help you choose a buyer who fits the board’s profile from the start.
How does the 2026 co-op law help me as a seller?+
It makes your timeline more predictable. Under the new rules, effective July 28, 2026, boards must acknowledge your buyer’s application within 15 days and issue a final decision within 45 days of a complete submission. One 14-day extension is permitted. Before this law, boards had no set obligation to respond by any particular date. Now you have a defined window, which makes planning and closing coordination much more straightforward.
Is now a good time to sell?+
Market timing is hard to predict. What you can control matters more: your unit’s condition, your price relative to comparable inventory, and your flexibility on the closing date. Spring and fall are traditionally the most active seasons, but a well-priced unit in good condition sells year-round.

Someday I might trade skyscrapers for a place by the ocean. Until then, New York is home.

Currently a resident of a Gramercy co-op, I have personally rented, bought and renovated in the city for more than a decade. Beyond real estate, I work on mobile apps, and have been part of the tech industry the past 15 years.

In my spare time, I enjoy exploring the NYC dining scene with friends and family, along with exploring new waters outside the city, drift diving with new friends.
