According to the National Association of Realtors 2013 Profile of Home Buyers and Sellers report, 42% of all homebuyers will first look online for properties, and 92% of homebuyers will use the Internet at some point during their home search. Once limited to brief property descriptions, todays real estate websites have evolved to offer a multitude of tools designed to modernize and simplify the home-buying experience. Buyers can now find property listings, street-view maps, virtual tours, market statistics and financial calculators online. Here, four of the best real estate websites for finding a home.

Zillow is an online real estate database of more than 110 million homes in the U.S. – including homes for sale, homes for rent and homes that are not currently on the market (used for comparative pricing and other info). Once you search for a property, the tabbed options become specific to that area. Features of the Zillow.com website include:

• Local info. Home values, demographics, user-submitted photos, schools and market reports.
• Zestimates. The Zestimate home valuation is Zillows estimated market value, calculated using a proprietary formula. (note: Zestimates should not be considered appraisals, and Zillow recommends supplementing the Zestimate with professional advice).

Trulia is an online real estate database that lists homes both for sale and for rent, and recently sold properties. Once you enter a city or zip  code, the tabbed options become specific to that market. Trulia.com website features include:
