PadMapper is a location-based apartment rental search engine with real-time filtering.
PadMapper's entire browsing interface is taken up by a full-screen map, and listings are loaded as the user moves around the map. Zooming into the map loads more listings in that area, zooming out broadens the search. Listings are filtered out or allowed back into the results as filter sliders are moved.
Apartment listings from hundreds of sites are included, including Craigslist, Apartments.com, ForRent.com, and Oodle.
