A $1 million NYC apartment sale routinely costs the seller $80,000 to $110,000 before a dollar reaches their bank account. That is 8-10% of the sale price gone to transfer taxes, broker commission, attorney fees, a co-op flip tax where one applies, and the payoff of whatever mortgage or underlying loan is still on the property. Most sellers I meet have never seen these numbers laid out in one place before they list, and the gap between "sale price" and "what I actually keep" is the single biggest surprise in an NYC sale. As a Licensed Real Estate Associate Broker with over 25 years closing deals across Manhattan, Brooklyn, and Queens, I build a net sheet for every seller before we agree on a list price, because the list price only means something once you know what it nets you.
This guide walks through every line item on an NYC seller's closing statement, in the order it typically appears, so you can build your own net sheet before you sign a listing agreement.
The Full List of Seller Closing Costs
Here is every cost a typical NYC seller pays at closing, roughly in order of size. Not every seller pays every line; flip tax only applies to co-ops whose proprietary lease includes one, and mortgage payoff only applies if you still have a loan.
| Cost | Typical Range | Who Pays / When It Applies |
|---|---|---|
| Broker commission | Negotiated, set in the listing agreement | Seller, per the signed listing agreement |
| NYC Real Property Transfer Tax | 1% under $500K; 1.425% at $500K+ | Seller, all NYC property |
| NY State Transfer Tax | 0.4% | Seller, all NY property |
| NYS Transfer Tax (mansion-adjacent tier) | 0.65% total on NYC residential sales of $3M or more | Seller, higher-value sales only |
| Co-op flip tax | 1-3% of sale price (building-specific) | Seller, only if the proprietary lease requires it |
| Attorney fees | $2,500-$5,000+ | Seller, contract through closing |
| Mortgage/loan payoff + satisfaction fee | Loan balance + ~$500 recording fee | Seller, only if a loan is outstanding |
| Co-op transfer agent / move-out fees | $500-$1,000 | Seller, co-ops only |
| Managing agent / condo move-out fee | $500-$1,500 | Seller, condos only, building-specific |
| Payoff of maintenance/CC arrears if any | Varies | Seller, only if behind on charges |
Commission itself is negotiated between you and your broker and set out in the listing agreement, never dictated by a formula I can quote in the abstract. What I can tell you with certainty are the government-set numbers: NYC's Real Property Transfer Tax and the state transfer tax are fixed by statute, not negotiable, and they hit every seller in the five boroughs. For a full walk-through of the tax mechanics themselves, see my NYC transfer tax guide.
NYC and NY State Transfer Tax, In Detail
New York City's Real Property Transfer Tax (RPTT) is 1% of the sale price for transactions under $500,000, and 1.425% for transactions at or above $500,000. New York State adds its own Real Estate Transfer Tax of 0.4% on every sale, rising to 0.65% on the full price of a New York City residential sale of $3 million or more (a 0.25% additional tax). These are the two costs every NYC seller pays with no exceptions and no negotiating room; they are collected at closing and paid to the city and state directly.
Worked Example: $800,000 Co-op Sale
- NYC RPTT (1.425%): $11,400
- NY State Transfer Tax (0.4%): $3,200
- Attorney fees: $3,000
- Co-op flip tax (2% of this building's proprietary lease): $16,000
- Co-op transfer agent fee: $750
- Subtotal before commission and mortgage payoff: $34,350
That worked example does not yet include broker commission or any outstanding mortgage balance, which is exactly why a net sheet has to be built for your specific numbers rather than estimated from a rule of thumb. A seller with no mortgage left on the unit nets a very different number than a seller paying off a large balance, even at the identical sale price.
The Co-op Flip Tax: Read Your Proprietary Lease
Flip tax is not a government tax. It is a transfer fee that some co-op corporations charge on every sale, written into the building's proprietary lease, and the revenue goes to the building's reserve fund, not to the city or state. Not every co-op has one. Where a flip tax exists, it typically runs 1% to 3% of the sale price, though some buildings calculate it differently, off the profit rather than the sale price, or as a flat per-share amount. Condos generally do not have a flip tax, though some condo bylaws include a transfer fee that functions similarly. Read the exact formula in your building's governing documents before you list; it is one of the largest line items on this whole sheet and it varies enormously by building. I cover this distinction in more depth in my co-op flip tax guide.

Mortgage Payoff: The Number That Changes Everything
Your outstanding mortgage or underlying co-op loan balance is not a "cost" in the traditional sense, it is money you already owe, but it comes directly out of your proceeds at closing and it is the single largest variable between two sellers with the same sale price. Request a payoff statement from your lender before you list, including the per-diem interest and any prepayment penalty, so the number in your net sheet is current rather than an old mortgage statement balance.
Building Your Own Net Sheet
A net sheet is simple math once you have every number: sale price, minus commission, minus NYC and NY State transfer tax, minus flip tax if applicable, minus attorney fees, minus mortgage payoff, minus any building move-out or transfer fees. What is left is what you actually walk away with. I prepare this exact document for every seller before we set a list price, because a price that looks strong on paper can net less than a lower price on a building with no flip tax and no assessments. If you are also weighing whether to sell occupied or vacant, that decision has its own math I cover in selling with a tenant in place, and if you own a co-op specifically, the board approval process affects both your timeline and your net, which I break down in selling a co-op vs a condo.
Net Sheet Checklist
- Get a current mortgage payoff statement from your lender, not last year's balance
- Read your proprietary lease or condo bylaws for the exact flip tax or transfer fee formula
- Confirm your commission rate in writing with your listing agreement
- Ask your attorney for a fee estimate before you sign anything
- Build the full net sheet before setting a list price, not after an offer arrives
Frequently Asked Questions
What are seller closing costs in NYC?
On a $1 million NYC apartment sale, seller closing costs routinely run $80,000 to $110,000, or 8-10% of the sale price, before any mortgage payoff. The lines are broker commission, the NYC Real Property Transfer Tax, the New York State transfer tax, attorney fees of $2,500 to $5,000 or more, a co-op flip tax where the proprietary lease requires one, and building transfer or move-out fees.
How much is the transfer tax when you sell a home in NYC?
The NYC Real Property Transfer Tax is 1% of the sale price under $500,000 and 1.425% at $500,000 and above. New York State adds 0.4%, rising to 0.65% on a New York City residential sale of $3 million or more. On an $800,000 sale, that is $11,400 to the city plus $3,200 to the state, or $14,600, paid by the seller at closing with no negotiating room.
What closing costs does a co-op seller pay in NYC?
A co-op seller pays the same city and state transfer taxes and attorney fees as any other seller, plus a flip tax if the building's proprietary lease requires one and a transfer agent or move-out fee of $500 to $1,000. On an $800,000 co-op sale with a 2% flip tax, those items total $34,350 before broker commission and any mortgage or co-op loan payoff.
Is a co-op flip tax a government tax?
No. A flip tax is a transfer fee some co-op corporations charge on every sale, written into the building's proprietary lease, and the money goes to the building's reserve fund, not to the city or state. Where one exists it typically runs 1% to 3% of the sale price, though some buildings calculate it off the profit or as a flat per-share amount. Condos generally do not have one.
How do I calculate my net proceeds from selling an NYC apartment?
Start with the sale price, then subtract broker commission, the NYC and New York State transfer taxes, any flip tax, attorney fees, your mortgage payoff and any building move-out or transfer fees. What remains is what you walk away with. Use a current payoff statement from your lender, including per-diem interest and any prepayment penalty, rather than an old statement balance, because the payoff is the largest variable between two sellers at the same price.
Want Your Actual Net Sheet?
I build a full closing-cost net sheet for every seller I work with, using your building's real flip tax, your actual mortgage payoff, and current transfer tax rates. No obligation. To try the math yourself first, the seller net proceeds calculator runs the same categories on your own numbers.
Request Your Free Net SheetThe sale price is the headline. The net sheet is the truth. Every seller deserves to see the real number before they commit to a list price, and building that number correctly, with your building's actual flip tax and your actual mortgage payoff, is where a strong sale starts.
