Even for affordable Washington Heights, this 862-square-foot two-bedroom at 143 Bennett Avenue near the Cloisters and Fort Tryon Park seems reasonable at $459,000. The kitchen and bath have been renovated and the co-op's gilded to the hilt with parking, storage, a tenant's lounge, and a children's play space. The catch? "The building doesn't allow cats or dogs," says listing broker Simone Song, who cites 143 Bennett's pet aversion as a big reason the unit hasn't moved. There's another two-bedroom on the block, so if you know how to wheel and deal, you may be able to use it as leverage to negotiate an even better price. —S. Jhoanna Robledo
