Google Maps now makes it easy to check out real estate listings in a certain area: click on the "Show search options" link next to the Search Maps button, and choose "Real Estate" from the drop down. Your search will map homes for sale, with photos and prices. Search blog Google Operating System reports that the results come from real estate site feeds, not Google Base. You can also refine your search by price, number of bathrooms and bedrooms. Looks like Google Maps is giving Zillow a run for its money, though Zillow offers home valuations for property that's not necessarily for sale.
