Combine Realtor‘s MLS-based national (i.e. US) search with HousingMaps UI (because who cares for Craigslist housing listings?), including smart ideas such as a history of past sales as featured by Redfin (who is not alone in overlaying local MLS data on maps). Mix with itinerary (by foot or car) and transportation applications
Is this a dare?
Olivier, great post! I’ve been toying with similar ideas mostly along the location-aware mobile device line, definitely an area with a lot of potential.
Absolutely food for thought. I think I saw recently where almost 75% of all buyers reference the web for real estate transactions.
