@Katie Jewell Wow to all that damage, drugs involved? 

A drug addict can't stop using until they stop hanging out with other addicts.

I'm a dealer for forevermark.

Safety or perceived safety   IE crime drugs homeless etc.

A few things you should know about the market, Philadelphia is extremely block by block, my office is in Northern Liberties where there are 600-700k houses, and a short drive north, and your in the drug capital of the city.

Car dealers give loans to anyone not legally dead, home ownership is tougher.

I'm a licensed dealer just outside of Charlotte. 

For a seller, you don’t have an open house three weekends in a row, where you can’t be home and have to clean all your stuff only to have the deal fall through because of a buyer who wanted to get a new ATV while they were under contract and the local Polaris dealer ran a hard hit on their credit and screwed up the mortgage underwriting process [that’s 100% a made up situation and hasn’t happened to me… oh wait].

I really think House Hacking is like the gateway drug into REI, so you are on the right path. 

For example, the claim that undocumented immigrants are associated with increased violent crimes has been debunked by nonpartisan studies, as has the claim that undocumented immigration is associated with increased drug crimes.A landlord who makes rental decisions based on such generalizations could run afoul of federal and state housing laws.
