 My area (Atlanta) is a very hot market. I found my house on Cinco de Mayo, emailed my agent, and we were looking at it that afternoon. By 9 AM the next morning the owners had accepted our offer. The house had not been on the market 24 hours. If I had not jumped on that house the moment it hit The MLS system,  I would not be sitting in the backyard enjoying it right now.  :-)
