1) Redfin.com: In addition to listings, this site offers information such as how long a home has been for sale, its last sales price, and its current value. It also provides virtual tours to listed homes.

2) Trulia.com: Like Zillow.com, which offers satellite views and the estimated values of each home, Trulia's "heat maps" show how hot or cold an area is based on prices, sales, and popularity among its users. Trulia.com also has free tools real estate agents can easily add to their own websites to increase functionality and traffic.

3) Maps.Google.com and Maps.Live.com: For a bird's-eye view, even 360 degrees in some cases, these amazing map sites offer a virtual perspective of available homes that's truly hard to beat.

4) Walkscore.com: Is an interesting site that rates any address based on the walking distance of its nearby stores, restaurants, schools, parks, coffee shops etc.

5) SchoolMatters.com: A Standard & Poor's company, this site offers parents (and potential home buyers) an objective rating of public schools and public school districts by region, including test scores and demographics.

GreatSchools.net offers similar info and ratings on private schools based on region.

Government Websites Government loan programs offer great opportunities for many consumers in many regions across the country, especially first-time buyers and veterans. The following websites are likely one of the first of many sites potential home buyers visit during this process:

2) Homeloans.va.gov: This site houses information about government home loan programs specifically for veterans.
