I did a guest post today on Seattle Bubble which gives a rundown of the real estate search apps available for the iPhone in Seattle. We’ve got a plethora of iPhone apps in the Seattle, including Zillow, John L Scott, Coldwell Banker and Redfin. We don’t yet have our own iPhone app, so I thought I would do an in-depth comparison of the four that are out there. Check it out to see who won the smackdown!
