What This Means

San Marino's luxury market is showing some fascinating mixed signals this March. Sales activity has absolutely surged—we're up 175 percent year-over-year and sold 11 homes compared to just 6 last March—suggesting strong appetite among high-net-worth buyers. That said, the month-over-month median price dip of nearly 10 percent and the jump in days on market from 69 to 78 days tells us the market is cooling slightly after what was likely a hot early spring push. This is pretty typical seasonal behavior, but worth noting as we move into the slower spring months.

What's particularly interesting is that homes are still selling above asking price at a 106.5 percent ratio, which indicates genuine demand despite longer marketing times. The gap between median and average prices—$3.2 million versus $3.6 million—suggests some premium estates are pulling up the averages. With 27 active listings sitting on the market for an average of 48 days at a $4.5 million median asking price, sellers are clearly being ambitious. For buyers, this could mean more negotiating room than we've seen in recent years, especially if properties don't move quickly. The spring market is unfolding predictably for San Marino's ultra-luxury segment.
