According to a recent report from comScore, online real estate site Trulia has the highest concentration of first-time homebuyers among top real estate search engines.

According to the National Association of Realtors, nearly 50 percent of homes were purchased by first-time homebuyers in 2010. First-time homebuyers are new to the home search process and typically need more guidance than repeat buyers. comScore’s report says that 43 percent of Trulia’s audience consists of first-time homebuyers. Realtor.com’s audience has 31 percent first-time buyers and Zillow’s has 28 percent.

“Out of all of the people who’ve contacted me through Trulia, about 90 percent have been first-time homebuyers,” says Deborah Bremner, an agent in Brentwood, CA. “What makes Trulia so appealing to homebuyers is that it allows a consumer who’s looking online for an agent to choose who they want to work with. On other sites, you don’t necessarily know the caliber of the agent you’re reaching out to, but with Trulia, you can determine who sounds like someone you’d like to work with. My client was extremely happy with the experience of being able to pick her agent on Trulia.”

Another valuable resource of Trulia is its Trulia Voices community, which offers insight on homeownership. Since being introduced in early 2007, more than 1.5 million contributions have been made in the Trulia Voices community. It is the largest and most active real estate community on the web.

Trulia isn’t the only site to engage insight from its users, though. In January, Zillow.com rolled out its ‘Agent Reviews and Ratings,’ which allows users to provide feedback on their experiences with agents.
