Has anyone received any updates on their investment recently?

If that all checks out, they will receive a reply from me. 

I have also seen the Zillow URL put on a yard sign and some property management companies have a "text to receive information" number on the sign.

And it's easy to source and document the cash. 

Recently, I've received an onslaught of BP solicitations. 

A buyer normally is willing to pay a higher interest rate since they may be looking for owner financing due to difficulty qualifying with a institutional lender.I have obtained a much higher interest rate than what I would receive in any bank.I have also used the same process with a buyer by giving him multiple notes with each secured by its own mortgage.

He has also performed maintenance on the property without requesting or receiving  compensation.

If so do you ask them to document what they are doing?

I never met him but we spoke often throughout the project, I received a fair price for the job and the job was done on time.

In Utah there is documentation that should be signed either way just to define the relationship.
