Hi! The most recent 2 Family that sold on Prospect Pl was 296 Prospect Pl. It closed Oct. 8th, 2013 for $2.2M, or $841/ft. That being said the Brooklyn townhouse market is already significantly different now than it was in October. Values are state-of-market and property-type specific, so if you'd like to know how much a particular townhouse could trade for in the current conditions please reach out and tell me more about that property. I'm part of the Townhouse Division at Keller Williams NYC and am townhouse fanatic so I'd love to share some knowledge and learn about another house's history!
