What This Means
San Mateo's May market is showing mixed signals as we head into the summer season. The median price ticked up 1.3% month-over-month to $1.795 million, suggesting prices remain resilient despite a slight seasonal slowdown. However, the year-over-year comparison tells a different story—prices are actually down 0.6% from May 2025, indicating we're in a plateau rather than an appreciation phase. Days on market crept up to 44 days, the longest stretch in recent months, suggesting buyers are taking their time and sellers don't have the urgency they once did.
What's particularly interesting is that homes are still selling above asking, with that 107.1% sale-to-list ratio showing San Mateo remains a seller-favorable market. Yet the gap between what's listed and what's actually selling—the median asking price sits at $1.348 million while median sales price is nearly $1.8 million—points to a disconnect in the active listings. Many homes on the market appear overpriced relative to recent sales comps. With 159 active listings accumulating an average of 64 days on market, inventory is building slightly, giving buyers more breathing room than they've had in years.
