I'd suggest checking in with some social service organizations within a few miles of the property to see if they work with people/populations in the area looking for this type of house.

We often mail out the first check when we encounter these situations. 

And how often do you go back to check on your properties? 

@Cameron Porter If you're looking at MLS properties, try focusing on ones that have been listed for 90 days or more, or check out expired listings—those are properties that were listed by agents but didn’t sell.

For that you probably need a check valve or something similar to stop the sewage from coming in when the city sewer fills up. 

As others have said, you need to check the regs in the area you are looking to make sure STRs aren't severely restricted.
