What a $3M+ NYC Apartment Purchase Involves

Buying a $3M+ apartment in NYC means a mansion tax of at least 1.50% of the full price, paid by the buyer at closing: $45,000 on a $3,000,000 contract, rising to 2.25% at $5,000,000, 3.25% at $10,000,000 and 3.90% at $25,000,000 and above. The rate applies to the whole price, so it is a cash cost on top of the down payment that a mortgage will not cover.

At this level the choice between a co-op and a condo shapes the whole purchase. A co-op purchase is a transfer of shares, and the board reviews the buyer's full financial package before approving it; a condo is deeded real property and generally needs no board approval. The mansion tax applies to both, since there is no co-op exemption.

Luxury Real Estate in Brooklyn

Brooklyn's luxury market ($3M+) includes full-service condos, pre-war co-ops in prime locations, penthouses, and townhouses. At this price point, buyers expect private viewings, early word on Coming Soon listings, and discretion throughout the transaction.

With over 25 years in NYC real estate, I search both REBNY RLS and OneKey MLS, including Coming Soon listings when the listing broker files them, and I call listing brokers directly about higher-price inventory. Use the form below to start a private search.

Tell me the price range and what you are after in Brooklyn. I read every request myself, and nothing you write here is shared with a listing broker without your say.

Frequently Asked Questions

What is the NYC mansion tax?
NYC imposes a mansion tax on purchases of $1M+ residential properties. The tax starts at 1% and increases progressively up to 3.9% for properties over $25M. This is paid by the buyer at closing.
Can I hear about luxury listings before they are widely advertised?
Sometimes. Some sellers start as Coming Soon on the RLS before full marketing, and REBNY rules set what can be shared and when. As a Licensed Real Estate Associate Broker at Keller Williams NYC, I search both REBNY RLS and OneKey MLS and tell clients about Coming Soon listings as soon as the rules allow.
