What This Means
Castro Valley's housing market is showing some interesting mixed signals heading into summer. While sales volume ticked up slightly month-over-month, the year-over-year decline of 20.4% suggests we're in a slower market overall compared to May 2025. However, the real story is in pricing: homes jumped 13.6% in median price from April, and sellers are holding their ground with a sale-to-list ratio of 107.2%, meaning homes are selling for above asking on average. This seller strength is a bit surprising given the slower year-over-year sales pace, and it likely reflects the limited inventory available—just 70 active listings for a market of this size.
What's particularly encouraging for sellers is that homes are moving faster. Days on market dropped from 56 to 44, a significant acceleration that suggests motivated buyers and competitive bidding when properties hit the market. The median asking price of $1.1 million for active listings sits well below what homes actually sold for at $1.27 million, indicating a potential disconnect that could push prices higher if that inventory gap tightens. Overall, Castro Valley remains a tight market favoring sellers, though the year-over-year sales slowdown hints that higher interest rates are still keeping some potential buyers on the sidelines.
