It is hard not to put a little trust in a "professional" that is supposed to help you. Just when you think you found "the" good one.......
Must be the nature of the beast. I think they are salivating over the thought of another hot market and how to pump it up again.
Don't beat your self up, I actually dug up a retired Realtor I knew (from the 80's when I did flooring in his investment properties) to help with my purchase. It's amazing how He turned into a full bore money grubbing realtor prick before closing.
Tuned out the owner of the place had two loans the house, and in order to sell it for the offer I made, the second mortgage holder had to take a cut. But he expected the realtors to take a cut as well. So the deal only had 3% in it, for the listing and the buyers agent to split. Can you believe my friend calls me up, telling me I had to pay the difference or the deal was off. Just like that, no talking to me, and laying a hardship story on me, about how he was really counting on that full 3% commission to pay bills. I would have understood and been inclined to make sure he was taken care of. I did dig him up out of retirement after all. I would have felt obligated to make sure he was happy with the outcome. With the way he went about it he was talking about sandbagging the whole deal.
