We got a letter too from this Susan person about buying our house

Susan wishes to buy my house - maybe when she's put me under!

We got a letter in the mail from this Susan Ferreira stating she would also like to buy our house. I'm guessing this is her business.

We too got a shifty looking note saying a Susan Ferreira would like to buy our house with this number. It was on yellow foolscap and on first glance looked handwritten. On second glance was computer generated. Has anyone responded to this person?
