How much is my Manhattan or Brooklyn apartment worth?

By Kristina Misailova, Licensed Associate Real Estate Broker, Compass

If you have plugged your address into an online estimate tool, you have probably seen a number that feels off. In Manhattan, those tools are usually wrong, and it is worth understanding why before you rely on one.

Why online estimates miss in Manhattan

National estimate tools work by comparing your home to nearby sales of similar size. That logic breaks down in Manhattan, where two apartments in the same building, on the same line, can differ in value by a wide margin based on floor, light, and condition. The tools cannot see any of that. They also struggle with co-ops, which make up a large share of NYC inventory and rarely report the detail these models need.

What actually drives your value

A real valuation weighs the things a model cannot:

• The line and floor. Higher floors, better light, and quieter exposures command more, even within the same building.
• Condition and layout. A renovated, well-laid-out apartment can far outperform a dated one of the same size.
• The building itself. Financial health, amenities, staff, and reputation all feed into price.
• Carrying costs. High maintenance or common charges reduce what a buyer will pay, because they raise the true monthly cost of ownership.
• Co-op vs condo. This affects the buyer pool, financing, and timeline, which affects price. If you are unsure of the difference, see our guide on co-ops vs condos.

How a broker prices it

An accurate valuation starts with genuinely comparable sales, ideally within your building or a very similar one nearby, then adjusts for the specifics above. It also factors in what is currently on the market competing with you, and how the market has moved in recent months. The result is a defensible number a buyer's agent will also arrive at, not an optimistic guess that leads to a stale listing.

When to get a valuation

It is worth getting a real number well before you plan to list, so you can weigh your options without pressure. Many owners are simply curious what their equity looks like in today's market, which is a perfectly good reason to ask.
