Washington, D.C.—Here is the smallest residential unit for sale in all of Washington (723 Longfellow St. NW, Unit 304). It’s in the small neighborhood of Brightwood Park. Top floor studio apartment at 264 square feet. Price is surprisingly low (for D.C.) $150,000. The neighborhood doesn’t appear to be that great, though. (Scroll down on ‘price’ link to see crime stats).
I also went around the nearby area of Kennedy and Jefferson Streets, which appear to be the center of crime locally per the referenced map on Trulia. It doesn’t seem to be any worse than Longfellow St. In fact, it may be better as there are fewer chain link fences. Here is a nice home on a corner lot with a wrought iron fence. Heading further west on Jefferson St., (west of 13th St.), the area becomes rather suburban and affluent. This turns into Sixteenth Street Heights neighborhood.
