Karen, I think there are some predators out there who will take advantage of a situation. If you do this business with a good moral compass, you can really do some good. Let me give a recent example. Just last week I received a lead from a very motivated seller. I talked with the lady and she didn't really give me much information other than the address and basics about the house. In researching it, I found she was 10 years behind on paying her property taxes. As it turns out, her house in in tax foreclosure. I made her an offer that I thought was low, and she was SO happy. She will be able to pay off her taxes and what she owes on the house and still walk away with a few thousand dollars. To her I am anything but a predator. It will hopefully be a win win for all involved. The people at the tax office are happy, she is happy and hopefully I will be happy.
Just be sure to always be up front and honest about your intentions and everything will be fine. Remember, they are the ones who have the choice to accept or decline your offer.
