As another FReeper posted, some of these nuts drive around taking pictures of your home to send you on a postcard solicitation. Are they SERIOUS?!!!!
I do that, but only on POS (exterior) properties that are owned by out of state owners. These are usually (and obviously) rental properties. The replies I get are either such owners who are tired of dealing with renters OR such out of state owners who are shocked at the pic I send, seeing how run down their properties have become. I bought one for $220k, renovated, then resold for $340k. The seller could hardly wait to liquidate that headache.
