All expenses must be paid from retirement funds. ( You can't use any personal funds or credit cards to pay bills on the rental). 

I have personally seen this come to 30-50% of the value of the home.

It almost seems to good to be true to be able to get the same returns as a Certificate of Deposit.https://finance.yahoo.com/personal-finance/best-high-yield-s...

FWIW there's locations here in CA where you can (in person) get fake DL, SS card, I9 cert, smog cert etc.

So instead of driving around you can use pin to find the property and the person.  

But, personally I wouldn't start the renovation until I'd had done a background check on the person who lost the property, to see if they have other assets they could sell to redeem the property or relatives who might help them out. 

Please also feel free to bring an investment, personal financial dilemma, or strategy question, and I am happy to discuss it with you... for entertainment purposes only.

i showed this home to another person first and thought it was a nice solid house and decided to buy this. price was good at the time How did you finance this deal?

But I'm always open to using different methods and trying new approaches.  

So you may be looking at a failure to communicate, that's where I would start, schedule an in-person meeting.
