Something I'm really curious about is what proportion of these vacant houses are in disrepair, if you've done any amount of urban exploring (or watched other people do it) it can be shocking how fast buildings can fall apart in some places. There are entire apartment buildings in Detroit, Gary, etc, with a negative value. The land isn't worth much and the building is in such bad shape the only thing to be done is to demo it and rebuild, which is quite expensive.
