Local insights from Redfin agents
The Cupertino housing market remains competitive. Over the past three months, homes have received an average of four offers and sold in about 10 days. The median home sale price reached $3.2 million, representing a 15.3% increase year over year.
The Cupertino real estate market continues to be a high-demand, competitive seller’s market. While demand is high, buyers are informed and selective; overpriced or poorly prepared properties experience longer market times and price drops.
