I've also had issues between male and females, so I typically try to only have one gender per apartment (either all males or all females).

I forgot to mention, I suggest you confirm with the responsible government body (town, city or county) that the encroachment and proposed easement do not and would not violate zoning restrictions, i.e. setbacks or utility easements.

I'm a bit hesitant because sports have destroyed my body haha.

Female is not responding back with a front picture of any ID.

Unfortunately, if you don't have the resources, its not very possible.here is my sort of "truth vs. reality:"  I think we'd agree that its true if you were a professional athletes you make lots of money (male more so than females, but that's not the point). 

Again, you have no body else to pursue because you bought via quit claim.

I rented out 4 Bedrooms to female professionals at $500-700 each plus utilities and paid all my mortgage ($1500).

I don't want to answer questions at 11:30 p.m. on a Friday, or deal with upset neighbors or regulatory bodies or cleaners or handymen or keypads gone awry, etc, etc.I had a property manager tell me that I have a few big faucets, and he has a bunch of tiny faucets.

Banks/financial institutions/servicers have regulatory bodies that hold them accountable for the proper and appropriate servicing characteristics of their portfolio.

Is there a certification body that checks your financials ie income and net worth and you get certified?
