When the seller only has a hand written Income (rent) and Expenses, 1 page, 1 month, what is the best way to confirm all income/expenses?

A well written management contract should clearly spell out what is expected of both the PMC and the owner, to PROTECT both and avoid misunderstandings.

., if 20% down payment in purchase agreement, have him place all those funds in escrow at the settlement company with clearly written signed addendum that should buyer not close by x date for any reason, those funds are nonrefundable and to be released to you, but all credited to buyer at settlement if they close.

@Adolphus Fletcher Like others have mentioned, gaining a non-recourse loan is a challenge unless in some cases where the loan is a commercial style loan of $5MM+ and the borrowing entity has strong income & assets to satisfy the lender's concern tied to the guarantee of the loan.

I can tell you this:  If you do a nice job on the rehabbing, you will never be short on customers. 

The appraisal costs on something like that would be pretty high as well.If you go the single asset route, you might get a nice little discount on fees by doing multiple at once.

The spreadsheets look pretty nice.

Quote from @Jay Hinrichs: We live two blocks from McDonalds, my son worked at McDonalds, he had a car, the weather was nice, but he would still order from DoorDash.

Would it make a nice mid term rental if I need a revenue boost?

There were several issues  but here are the big ones that ultimately led to us backing out of the deal. (1) The right of first refusal provision which mean't the seller had to convey the sale info to the cell tower company and then receive written permission for the sale to go through.
