We belong to the local landlord association, that helps! 

A background report/Consumer Reporting Agency (CRA) cannot verify specifically whether that SSN belongs to that name/individual.  

STLREIA.com is one I still belong to and a great place to learn a lot.  

I spoke to the agent and learned that the property was one of several that belonged to a trust.

Just a few examples from different forums I belong to.

I would definitely have an attorney read the original lease and see what their interpretation is of which outside space belongs to which unit.I would continue to serve him the three day notices and if he does not comply then you have a chance to go to court and try to evict him.

Then you REALLY have one-million in cash that belongs to you--to risk on investing, without the risk of losing the cash cow.I assume you live well, and 10 million a year won't make that much difference in your life than 1 million a year...You can only spend so much and still live a splendid lifestyle.But if something happens and you lose that cash cow to bank foreclosure, sleeping on a park bench could be a reality.Just my 2 cents.https://www.youtube.com/watch?

Second, if you are calculating an IRR that typically indicates a projected sale of the property, are these not going to be long term-holds? 

Are you managing three rentals for yourself or are you managing 400 with most of them belonging to others?

My friend advised me to get a property manager immediately and have a new lease stating that they're renting out 1 bedroom, move their belongings out of the other 2 bedrooms and immediately have the utilities switched in the tenant's name, which she would need to call to start but with this rift, I'm not sure this would happen.
