Process Stage: Closing

Executive Thesis

Selling a property in New York City incurs some of the most aggressive closing costs in the nation. To calculate true net proceeds, sellers must understand the structural impact of state and local transfer taxes, and how co-op flip taxes can heavily dilute final profitability.

Quantitative Framework: The Transfer Tax Burden

In NYC, sellers bear the brunt of transfer taxes:

New York State Transfer Tax: Baseline 0.4% on real property conveyances. Under a progressive structure, residential properties in New York City selling for $3,000,000 or more are subject to an additional 0.25% state tax, bringing the effective state rate to 0.65%.

NYC Local Transfer Tax: Separate from the state tax. Typically 1% for sales under $500,000 and 1.425% for sales over $500,000.

These taxes are cumulative and entirely separate from each other.

Quantitative Framework: The Co-op Flip Tax

Many cooperative buildings impose a "flip tax" — a transfer fee paid back into the building's reserve fund upon the sale of a unit. Despite the name, it is a private building fee, not a government tax.

Depending on the building's specific bylaws, the flip tax can be calculated as:

• A flat percentage of the gross sale price (e.g., 1% to 3%).
• A percentage of the seller's net profit.
• A fee per share owned.

Because this severely impacts the seller's bottom line, identifying the building's exact flip tax structure is a mandatory first step before establishing a listing price.
