But being in a "covered" position gave me some protection.  

Thank you for being so generous with your expertise.

Its usually best to leave the flooring for last (unless you take the time and material to cover it with paper to protect the new installation.)

A renter is also protected from an owner who tries to pass property liability on to them.  

Hi,Thank you to everyone who responded with recommendations for a closing attorney.I'm now looking for an asset protection attorney that works with RE investors, preferably in North Metro Atlanta area.

   While you cannot charge the one that has orders, the other one likely does not have the same protections and apparently can afford to stay but just wants to move to save himself money rather than find another qualified roommate to share with, so he is trying to make this your problem instead of his.  

If there is a benefit to this regarding asset protection or anything else.

I thought ECOA protected people based on marital status? 

All in all, I suspect if you own the underlying land, have several mobiles in a compact area, and have expertise in the area (repair, the tenant demographic, etc), then it could work well.

Such as law that protects other tenants being effected by 2nd hand smoke?
