I think I've had 8-10 short-term rental and long-term rental deals close with this other program in the past two months alone.If you are in need of a new prequalification letter and a different look at the deal from another program, I would be happy to help before we hit the weekend.

I would mail them a letter or put them on notice.

That would be his issue with his lender.You would have the option of forcing him to complete the deal, he then has to work out the problems between himself and his lender, that is none of your problem or business.Have your attorney or the real estate agent's broker send a strongly worded letter as a warning about the consequences ( a lawsuit he is unlikely to win).

I've done some research and see some suggesting randomly showing up at the house (don't want to do that) or sending a letter/mailer (those things are usually thrown out).

If no one answers the door, you can put that in a letter / notice and post it on their door.  

If you have no lates in the last 12 months and re-established credit meaning you have atleast 3 tradelines you have made ontime payments on for the last 12-24 months you may be eligible for VA financing with 580 min or lower scores depending on the scenario.Most of the time these type of files with be a total cluster and require 30-40 conditions ranging from letters of explanation, additional documentation, and or other to close.

You're going to be call or mailing land owners....just saw a guy mailing out 34,000 mailers...probably 60cents or more a letter....so just that one mailing is a $15,000 up front investment....plus you need to have systems set up to respond to that amount of mail and response, and the money either to buy those deals that come thru or if you're going to try to wholesale them, then the money to find your end buyers.   

A lot of those letters are fake however and we double check their authenticity with Pet Screening.

Now I have talked to my tenant on the phone, and she said she got the letter.

Also, if you didn't receive a pre-approval letter from a VA approved lender with the buyers offer ask for one.
