We had an attorney draw up an LLC and write up the partnership agreement. 

If you ever need help or a second opinion on anything, even though I know there are people out there much more qualified than me, don't hesitate to write me a message!

@Scott TrenchI not only would like to see an android app, I'd like to help write it.  

Not what I want.What I am considering is making an offer above asking, then writing a separate addendum where the seller provides "assistance" and brings me a check at closing. 

All contracts, unless the seller has specifically forbidden it in writing, are assignable. 

I direct the investments via the LLC bank account - I write and sign the checks directly.  

So it rental sign goes up May 2015 then you write off in 2016!?

I'm actually reading his book second chance as I'm posting, and it's nothing to write home about.

Even with your public management company, just write up a simple management agreement.

Therefore, you will need to go through the entire process without cutting corners or getting impatient (the real enemy of dealing with seniors).Since I presume this is your first package deal, I suggest you plan on showing up with two note pads, one for each of you, and ask your seller to make notes mirroring what you write down in your well-rehearsed meeting.
