Hi there, Right next to my investment property in Pensacola is an old abandoned eye sore of a house on a corner lot between two intersections. across the abandoned house is an open lot that has been rezoned recently for multi family and the owner has begun construction past week. buying out the abandoned property would help me on multi levels.

Kind of an eye sore of a neighborhood.  

Has anyone heard of investing in residential treatment facilities (group homes)?

I would personally just visit those new mobile home models and copy every inch of them exactly, including wall and floor treatments, cabinet hardware, etc.

As a self storage investor, Podcasts like yours are sorely needed that bring more in-depth information.

And you'll get positive tax treatment for the cost of your financing. 

Did they have to do ozonation treatments or any other extreme odor remediation?

If you own it at least as year you will get capital gains treatment on the proceeds. 

They swab, tell you the level and threat risk and provide a treatment plan if necessary.
