Would you be suspicious?

[Bienes Raices]

I had someone come two days ago who was on SSI and child support (did not have enough gross income to qualify). Yesterday, I received another phone call, from a different phone number but same area code as the first call. It's from another area of the state from which I rarely get calls. Same type of person, asking to come see the house. Could it be relatives or friends of the first individual trying to get the place for her under a different name, or am I being paranoid?
