Four out of ten deals fall through because the seller changes there mind due to sellers remorse.  This even applies during a soft market. If you offer full asking price then they can be forced to sell or pay a full commission to the listing Broker. I have learned my lesson the hard way. If a seller is out of line on there price that's one thing however, if they are close to what is believed to be the right price and you really like the property you must offer full price.

Trust what I'm saying. Call me if you want to hear some crazy stories
