We take every 1-, 2- and 3-family home sale recorded with the NYC Department of Finance since January 2024, drop non-market transfers (family sales, $10 deeds), and compute the typical price per gross square foot for your ZIP code and home type. Your size times that figure gives the middle of the range; the range itself covers the middle half of sales.
It is a good starting point, usually within the range shown. It cannot see renovations, a finished basement, a legal extra unit, parking, or a bad block. That is why the free market analysis exists.
A comparative market analysis (CMA) is prepared by a real estate agent from recent comparable sales, and it's free. An appraisal is a formal opinion by a licensed appraiser, usually ordered by a lender for a mortgage or refinance, and typically costs a few hundred dollars.
Before you sell or list. Before a refinance or a home equity line of credit, since lenders lend against your equity. Before appealing your property tax assessment. When you inherit a home or settle an estate. And once a year, simply to know where you stand.
Zoning sets how much floor area can be built on each lot: the lot size times the zone's floor area ratio (FAR). If your building is smaller than that, the difference is unused. Builders pay for it: in the Bronx, land sold in 2024–25 for a typical $92 per buildable square foot. A 2-family house on a lot zoned for an apartment building can be worth more as a development site than as a home.
Every January the NYC Department of Finance publishes a market value for your home. If it is higher than what your home would actually sell for, you can file an appeal with the NYC Tax Commission. For 1–3 family homes the deadline is in mid-March (March 16 in 2026). Our tax check compares the City's number with real sales near you.
No. The estimate needs no sign-up. If you ask for the analysis, Leo calls once with the number and answers your questions. You decide what happens next.
