I didn't use a real estate agent to sell my parents home (after they passed). I guess I was lucky it was in the "right" area. There were people leaving notes on my door and in my mailbox begging me to sell it to them.
I have a contract on my non-flooded home in an area hard hit by Katrina. I listed by owner, and I have a waiting list of people who want the house should the contract fall through.
I've even had real estate agents contact me, hoping to work a deal whereby they get some sort of commission.
