I've read (all my knowledge is theoretical) that tenants on government assistance can be really rough on properties (I also see that as painting with a broad brush) but the government assistance side of that is pretty stable income, and it doesn't seem terribly difficult to raise rent either, just requires 60-days notice instead of 30.
