I've gotten a few letters from realtors asking if my house was for sale because they had a client that really wanted to move into the area. Out of curiosity, I contacted one of these realtors, and they asked me questions about my house -- how many bedrooms, bathrooms, detached garage, etc. When I said it was 2 bedroom, she said "oh, well, my client wanted a 3 bedroom. but since you are thinking of selling anyway..." -- it felt like a scam, like they were just trying to see who was willing to sell their house so they could be my realtor.
