March marks the transition from early spring momentum into a more active phase of the San Mateo County real estate market.
The local market continues to move forward, but broader economic uncertainty has become a much bigger part of the conversation. Mortgage rates have remained relatively stable on a weekly basis, though daily movements have become more noticeable. Oil prices have risen sharply in recent days. Stock markets have turned volatile again. And locally, home prices remain elevated, reinforcing the strength of the San Mateo County market even as outside conditions shift.
Here is what the latest data shows and what it may mean moving forward.
Mortgage Rates Have Been Stable Weekly, but Daily Volatility Is Back
Mortgage rates remain one of the most important factors shaping buyer activity.
According to the latest chart, the weekly average 30-year conforming mortgage rate was 6.0% as of March 5, 2026, essentially unchanged from the prior week. However, the daily average rate rose to 6.14% as of March 6, increasing by 15 basis points since the start of the Iran war.
That distinction matters.
Weekly averages suggest mortgage costs have not shifted dramatically yet, but daily changes remind buyers that borrowing conditions can move quickly when global events add uncertainty to financial markets.
For buyers, this means payment sensitivity remains important.
For sellers, it means serious buyers are still active, but many are watching financing conditions closely.
Small rate changes can still influence timing and confidence.
Oil Prices Are Rising and Adding Pressure to the Broader Economy
Oil prices have moved sharply higher in a short period of time.
The latest chart shows crude oil climbing significantly since early February, with especially dramatic movement after the start of the war. These kinds of swings can affect far more than gas prices. They can influence inflation expectations, transportation costs, consumer sentiment, and overall economic confidence.
Housing does not operate in isolation from these trends.
While the United States is less exposed to oil shocks than some other parts of the world, rising energy costs still affect household budgets and can shape how consumers think about major financial decisions, including buying or selling a home.
For now, this is more of a macroeconomic pressure point than a direct local market shift. But it is a variable worth watching.
Broader costs influence buyer psychology.
Stock Market Volatility Is Back in Focus
Financial markets have also become more unsettled.
The chart tracking the S&P 500 & Nasdaq shows noticeable swings, with both indexes pulling back from earlier highs. In higher-cost and more affluent markets like San Mateo County, stock market movement can carry added weight because household wealth, down payment funds, and consumer confidence are often more directly connected to financial market performance.
This does not mean stock volatility immediately changes housing demand. But it can affect how decisively some buyers move, how comfortable they feel stretching on price, and how sellers interpret the strength of the market around them.
In other words, volatility does not necessarily stop activity, but it can change the pace and tone of decision-making.
Confidence matters in a high-value market.
San Mateo County House Prices Remain Elevated
Despite shifting headlines in the broader economy, local home prices remain resilient.
The latest San Mateo County house price chart shows that the 3-month rolling median house sales price in February 2026 was up about 4% year over year. While monthly and seasonal fluctuations are normal, the larger trend remains clear: house values in the county continue to hold at historically elevated levels.
This is an important reminder that local housing markets are shaped by both national conditions and local supply-demand dynamics.
Even with more uncertainty in the financial backdrop, the San Mateo County market continues to reflect long-term demand, constrained inventory, and the desirability of the Peninsula.
Price strength remains intact.
What This Means for Buyers
The market is still active, but the financial backdrop is becoming more complex.
Mortgage rates are relatively steady on a weekly basis, yet daily volatility has returned. Stock market movement and rising oil prices may affect confidence, especially for buyers who are closely watching monthly costs and broader economic conditions.
At the same time, local home prices remain strong, which reinforces the importance of preparation and clarity.
Buyers who understand their financing, know their priorities, and are ready to act decisively will be in the best position as spring activity builds.
Preparation creates flexibility.
What This Means for Sellers
The San Mateo County market continues to benefit from strong underlying demand, but sellers should not ignore the changing mood of the broader economy.
As buyers weigh financing costs and react to economic headlines, thoughtful pricing, strong presentation, and strategic positioning become even more important. In a market like this, homes that feel well-prepared and well-understood will stand out.
Local pricing remains resilient, but confidence still needs to be earned.
The homes that stand out will command attention.
