Ditmas Park is a landmarked Brooklyn neighborhood recognized for its freestanding Victorian, Colonial Revival, Tudor, and Craftsman homes set back from the street with porches and landscaped yards. The B and Q trains serve the neighborhood at Cortelyou Road, Beverley Road, Newkirk Plaza, and Avenue H stations, and Prospect Park's 526 acres of green space sit just to the northwest. The historic district encompasses roughly 2,000 residential buildings dating from 1902 to 1914, making it one of the city's best-preserved collections of early 20th-century residential architecture.

Broker Commission Disclosure: Broker commissions are not set by law and are fully negotiable.

How working with a buyer's agent works: I work for you, not the seller. Before I show you anything, New York brokerage rules ask us to put that in writing: an agreement and a disclosure that say I work for you and negotiate on your behalf. The agreement is non-exclusive: you can work with other agents, it runs for a short fixed term we agree on, and you can end it with a note. You may attend open houses independently without an agreement. Read how it works
