The current owner is US Bank Trust in Oklahoma.

I wanted to address Tom concerning " why not sell" .

I told her this single sentence thing doesn't address the possible existence of a lease, and to cancel the inspection, I'm not moving forward at all until this is nailed down in writing.

Yeah if it's a timing issue then Private Money can be tricky because it takes time to build that relationship and trust.

If I have addresses already in mind, can I purchase now?

And has any other LLC used that address? 

Also when you say you negotiated for all 3 of us to take over the mortgage that worries me because the "thing" taking over the mortgage should be a trust, LLC, etc. and never ever an individual person.

Its more like you type in an address and it mails in the vicinity. 

Don't trust what they give you.You can even ask to see Schedule E, not that they will comply. 

Please Break down in simple steps and how does the seller trust you enough to sign a contract?
