If you don’t like the idea of paying $1,000 a square foot to own in Brooklyn, maybe it’s time to check out Flatbush. This sweet semi-detached two-family, built in 1930 according to the listing, appears to have all its original moldings, French doors and hardwood floors. The kitchens have been nicely updated with white subway tile. It’s configured as a three-bedroom duplex over a three-bedroom rental. And there’s a garage. At 2,421 square feet with an ask of $599,000, that works out to less than $250 a square foot. What do you think of it?
