This tool allows users to select the homes that best compare to their own, which Redfin said is important because a home's actual value is often affected by factors that are difficult for computers to capture, such as a certain view, traffic noise or unique architectural features. It also generates two comp properties automatically.
"Redfin engineers and designers focused on building a tool that gives homeowners the ability to choose the best comparables from a list based on things machines can't calculate," said Bridget Frey, vice president of engineering.
"Price is a key factor in selling a home faster and for more money, so having a more accurate starting point can be of real value for homeowners."
