9. The Most Expensive Flatbush Mansion, 85 Buckingham Rd
This quaint Dutch Colonial Revival on Buckingham Road made a splash when it hit the market in March 2020. The three-story, seven-bedroom home came with a price tag of $3,625,000, making it the most expensive house in Prospect Park South when it sold. A big selling point is the home’s huge backyard, or “hidden private park,” as it was referred to in the listing. Out back, there is a pond with a waterfall and space to add large recreational features like a swimming pool or tennis court.
