Why It Made the Cut: Zillow’s robust database with many listings and evolving algorithms makes it one of the most accurate site estimators available.
Zillow boasts that it is one of the most frequented real estate websites in the United States. So it should come as no surprise that its highly accurate home value estimator is a tool that adds to its popularity. It has a very low median error rate for on-market homes of 1.9 percent and off-market homes of 6.9 percent. Zillow also has the most extensive database and an evolving proprietary algorithm, making its estimates, known as Zestimates, more reliable than those of most other sites. Additionally, Zillow has handy tools for homeowners to sell their homes. The only drawback is the user interface for homeowners can be dense with information, making it hard to explore. But it does deliver many helpful tools for homeowners, including home equity estimates and adjustable sales proceeds. A home value comparison tool also allows users to select specific homes in the area and directly compare specs and valuations. Users can feel confident that this platform will provide accurate home values.
