What This Means
Castro Valley's real estate market is showing mixed signals this March. While sales activity surged 81 percent month-over-month—jumping from 16 to 29 homes sold—this uptick appears to be seasonal spring momentum rather than a sign of fundamental strength. The year-over-year picture tells a different story: sales are down nearly 30 percent compared to March 2025, suggesting underlying softness in buyer demand. Median prices have fallen 15.3 percent annually and 4 percent just this month, landing at $1.08 million. This cooling is likely driven by persistent higher interest rates keeping some buyers on the sidelines.
The market is adjusting accordingly. Homes are staying on the market about a week and a half longer than last month, and active inventory has climbed to 57 listings—a healthy supply level that favors buyers. What's encouraging is that sellers are still getting nearly full asking price at a 101.4 percent sale-to-list ratio, indicating homes that are priced right still attract attention. At $596 per square foot, values remain reasonable for the East Bay. For now, Castro Valley is a buyer's market, but not dramatically so. The real story is normalization after years of explosive growth.
