Windermere has just released a new mobile app for iPhones. It has all the search capabilities of www.DaveSuttonHomes.com (and a few more). It will let you search by the usual criteria, select your favorites, and then create an optimized Driving Tour to see them all with the least amount gas!. GPS based "Nearby listings" and "Nearby Open Houses", too, One popular feature is "More like this" so when you find a home you like, you can find similar homes within a one mile radius.
See how it works here which includes a link to download the app.
At the "My Agent" menu (under "More") if you'll select Dave Sutton we'll be able to share notes and other information. Enjoy !
