I'm a tenant my landlord used to sit outside the house late at night watching the person who lived in the unit next to me to make sure her boyfriend wasn't coming over at night.

As that will at least help folks that you reach out to know that you are a real person, with a picture and professional bio.

Unrelated persons/noise. 

But for some reason I’m still not fully clear on how to personally own or have more the 8-10 mortgages for rentals.

We may get one to Philly again, in person, in the Fall.

On entering the bathroom, I discovered the powder, and the odor, were INCHES of talcum powder on the floor where this person apparently "bathed" with the talcum powder, then carried/spread it throughout the apartment.

Any suggestions or personal experiences for the FHA 203k loan?

You should be able to pull a HELOC on your personal residence and not even use that much of it with all that equity you have.

A good person to link up with would be @Ryan Blackstone. 

I understand I have should have put the deed in my personal name instead so I could pull the permits myself even though I’m the President of the corporation.
