I guess this would be an easy question to answer. Just collect data on how long each house stays vacant, you can get e.g. the average time a house in Baltimore will stay vacant, which type of house and which neighborhood is more likely to stay vacant longer, etc. I did a quick google search for some summary on this statistic, but found nothing (unsurprisingly since I have never done this kind of research before). Since this is HN I’m sure if there is will somebody can provide us with a summary—or at least an answer—of whether this is the case.
