Google Real Estate

Google has added real estate listings to it's local mapping service.

Visitors to google.com who search for the terms ''apartment rental" or ''homes for sale" are asked to type in a location. Results are then displayed with red push pins on a Google map.

Tony Longo, the founder of Condodomain.com, which carries listings of Boston's most luxurious condominium projects, said his firm submits listings on behalf of clients to Google, which he said quietly rolled out the service weeks ago. Google, like Trulio.com, Propsmart.com, and his site, is a ''vertical search" provider that compiles listings from various sources.
