Note buyers for owner finance buyers without socials

[Joe S.]

In Texas there are quite a number of people with work permits that do not have socials. In the event that a seller was to owner finance a property to a buyer without a SSN, is there a market for the Note to be sold to a note buyer?  I have heard from a number of Note buyers that they would want the buyer to have at least 580 credit score. This does not seem realistic to have a credit score of 580 if a person doesn’t even have a SSN. 
Has anybody found a workaround for this or would the seller simply have to hold the note long-term without the option of selling it?

when I was buying notes I did not even run credit.. but I only paid 10 to 20 cents on the dollar.
