Being on an alleyway, this home has a few strikes against it already. This one is actually at the corner of two alleys. It's a shame, really, because the house itself is a good size and has lots of potential.
Warren St, although a park-one-side-only street, has a number of nice homes (this isn't one of them). the west side of the street has a few that have recently been painted, and one home in the middle of the block even has a spacious side yard. My feeling is that is the best way to improve a neighborhood: lead by example, and (hopefully) the rest will (eventually) follow.
