What Zillow shows

What it means for buyers and sellers
Redfin gives Cupertino a Compete Score of 90, "most competitive." Most homes get multiple offers, often with waived contingencies, and hot homes sell for about 12% over list in around eight days. The lower median and the higher Zillow index point in different directions, a reminder that a three-month median moves with the mix of homes that happened to sell.
Redfin figures cover the three months through September 2026 and compare with the same period a year earlier. Zillow's Home Value Index is a typical-home estimate, not a sale price, so the two numbers measure different things and won't match exactly.
