Trulia combines social networking with mapping and search technology. Trulia gives you a high-tech way to find homes for sale and recently sold. Use the different sliders and checkboxes to focus your search (price, square footage, and the all-important number of bathrooms). Trulia will display qualifying homes that are for sale in the specified area, overlaid on a map. The site includes useful, city-specific real estate guides containing additional data on average home sale prices, most popular neighborhoods, and crime statistics.
The Trulia Voices section hooks you up with other people to discuss neighborhoods, housing issues, or real estate in general. Trulia is relatively new, so that section may be a bit sparse, but if the site gains recognition, Trulia Voices may prove to be the most useful tool of all. Check it out!
