Jeff - what a nice person you are. But, the previous poster is dead on. There's no guilt in buying a short sale. A short sale is a win for the seller and for the bank, and for our overall economy.... and structured and managed carefully, a win for the buyer, as well. When we work with sellers in a short sale situation, and we're successful, they hug us and cry and thank us for helping them to avoid foreclosure. Then, they lick their wounds and plan to get back on their feet financially to buy again in a couple years. It's all good. Just beware of the risks in a short sale and make sure you're covered.
Best of luck!
