Renting to someone without SSN?

[Beth L.]

So I had someone today call in response to my "For Rent" sign. She said that she is looking for a place for her, her boyfriend and his two brothers. She said that she is having a hard time finding a place. The three men are Spanish and another landlord told her that he will not rent to Spanish people.

I told her that it is illegal to discriminate race, so as long as they qualify after the application/background check they could be considered. She said that they don't have social security numbers.

I am not having a good feeling about this. I haven't had anyone apply without a SSN and don't think that I can run the background/credit/criminal check without one. Does anyone else have experience with this type of scenario?
