Truzip.com. There are several online real estate portals like Zillow, Trulia, etc. on the market today. How Truzip differentiates is that we provide the home buyer with the best deals in their search area, not just the home listings. To do this, we use patented valuation algorithms to determine the "best deal". Internal testing has shown that homes we determine to be "good deals" sell 30% faster than others. Take a look at truzip.com for details.
