Off of the purchase contract, I would verify proof of funds, ask for prequalification letter from a lender if buyer is receiving a loan, with a good faith deposit.

Not certain I am doing this part correctly -- @Bob PThe 1st letter we get is a letter stating it appears something may be wrong with a conveyance that occurs and they ask for contact from borrower to explain the conveyance that occurred. 

If they refuse, then send a demand letter.

From there, I hand wrote letters to distressed owners of properties, and did some fix and flips. 

Ignorance of lead paint presence doesn’t exempt you—you must have a compliance letter to avoid strict liability.If you rent to a couple or a single woman and she becomes pregnant, the law requires you to delead the unit.

This amount is fully refundable for any reason if you do not execute a loan commitment with us and you request in writing within thirty(30) days of the date of this letter the return of the $10,000.signing of the loan commitment, a commitment fee equal to five percent (5%) of the Financing Request is due; three percent (3%) would be payable at the signing, and the remainder would be payable from the loan proceeds at closing.

Off market deal --> send a letter to the landlord who owns the house outside their state. 

I only know it was going to be a DSCR loan with them putting about 20% downCan they get a letter from the city saying they're grandfathered in and allowed to rebuild a duplex if it's every destroyed? 

Then got a letter to return the deed and they would refund since the original sale was invalid.
