To buy a house in San Mateo in 2026, plan on about $1.4 million for a typical home and more for detached houses west of El Camino Real. Arrive with full loan approval, read the disclosures before offer day, and expect well-priced homes in popular areas to sell above their asking price.
Step 1: Match your budget to the right part of town
San Mateo has more variety than almost any city on the Peninsula, from studios under $500,000 to houses over $10 million. In late October 2026, Highnote360’s data showed 99 active listings, a median list price of about $1.39 million, and 43 homes pending sale.
The pending sales show what is actually moving right now:
| Price band | Pending sales (Oct 2026) | What it usually buys |
| Under $1M | 13 of 43 | Studios and one- and two-bedroom condos downtown, along El Camino Real and near the Bay |
| $1M to $2M | 17 of 43 | Larger condos, townhomes and smaller houses, mostly in the 94401 and 94403 ZIP codes east and south of downtown |
| $2M to $3M | 7 of 43 | Three- to five-bedroom houses, spread across the city’s family neighborhoods |
| $3M and up | 6 of 43 | Larger homes, almost all in the 94402 ZIP code around Baywood, Aragon and San Mateo Park |
If your budget sits on the edge of two bands, look at both. A remodeled townhome near a Caltrain station can be a better long-term fit than a dated house in a quieter area, and the reverse is just as often true.
Step 2: Check the flood map before you fall in love
Flood insurance is the cost that surprises San Mateo buyers most, and most buying guides skip it. Parts of the city east of Highway 101 sit close to the Bay, and the city’s flood maps have changed several times.
The good news is recent. After the North Shoreview levee and pump station upgrades were finished in 2023, FEMA revised its map on October 11, 2024. About 1,600 addresses in North Shoreview and North Central moved out of the high-risk flood zone, so lenders no longer require flood insurance there.
Other areas still need a check. Before you write an offer on any east-side home:
- Look up the address on FEMA’s flood map or the City of San Mateo’s flood zone page.
- Read the Natural Hazard Disclosure in the seller’s package.
- Ask your insurance agent for a flood and homeowners quote, and add it to your monthly budget.
- Ask whether the home is inside a local assessment district that pays for levee work, since that adds a line to the property tax bill.
Step 3: Understand how offers really work in San Mateo
Many listing agents in San Mateo set the asking price low to attract more buyers, then set an offer date. As a result, the asking price is often a starting point, not the price.
Highnote360 reviewed the 50 highest-priced San Mateo sales from late 2025 to October 2026, mostly houses in the 94402 ZIP code west of El Camino. Of those 50 homes:
- 31 sold above the asking price, 10 sold at it and only 9 sold below.
- The typical home sold about 4% over asking.
- The biggest jumps came from homes listed noticeably low. Five homes sold for 24% to 39% above their list prices. A house listed at $2.6 million, for example, closed at $3.625 million.
What to do with this:
- Price your search by recent sales, not asking prices. If similar homes on the same street sold 10% over asking, a home listed at $3 million is really a $3.3 million home.
- Get ready before offer day. Read the disclosures, get your loan fully approved and, if the seller hasn’t provided one, consider your own inspection before you offer.
- Make the offer easy to accept. Short or no contingencies, a quick close and flexibility on the seller’s move-out often matter as much as an extra $25,000.
Homes that sit on the market for 30 days or more are a different story. Those are where you can negotiate, so watch for price cuts.
Step 4: Add up the costs most buyers miss
| Cost | Typical amount | Notes |
| Down payment | 10% to 20%+ | Most San Mateo houses need a jumbo loan |
| Property tax | About 1.1% to 1.25% of price a year | 1% base plus local bonds and assessments; varies by area |
| Homeowners insurance | Varies widely | Get quotes before you offer, since some insurers limit new policies in California |
| Flood insurance | $0 to several thousand a year | Only where FEMA or your lender requires it, but worth pricing on the east side |
| HOA dues | Often $400 to $900+ a month | For condos and townhomes; check the reserve fund and any special assessments |
| Buyer closing costs | About 1% to 2% | Lender fees, title insurance, escrow fees and prepaid items |
Step 5: Choose your commute and your school
San Mateo has three Caltrain stations: downtown San Mateo, Hayward Park and Hillsdale. Since Caltrain’s electric service began in September 2024, express trains reach San Francisco in roughly 25 to 30 minutes, and local trains take longer. Hayward Park is served by local trains only, so check the schedule if you plan to commute from there.
Public schools are run by two districts. The San Mateo-Foster City School District covers elementary and middle school, and the San Mateo Union High School District runs Aragon, Hillsdale and San Mateo high schools. School assignments do not always follow neighborhood names, so confirm the school for the specific address with the district.
Step 6: Close in about a month
In California, escrow usually takes three to five weeks. During that time you remove your contingencies, finish your loan, sign the documents and do a final walk-through. Sellers must give you a Transfer Disclosure Statement and a Natural Hazard Disclosure, and you should read both before your contingencies end.
Questions buyers ask
Is San Mateo cheaper than Burlingame or Hillsborough?
Yes, on average. San Mateo has many condos, townhomes and smaller houses, so its typical price is well below its northern neighbours. Its best streets, such as those in Baywood and San Mateo Park, are priced closer to Burlingame.
Should I offer over asking in San Mateo?
For well-priced houses in popular areas, usually yes. Check recent sales of similar homes first, and don’t assume every listing will go over. Condos and homes that have been on the market for weeks often sell at or below asking.
Which part of San Mateo is best for commuters?
The areas near the downtown and Hillsdale stations, including Bay Meadows, are the easiest for Caltrain riders. Homes near Highway 92 and Highway 101 suit drivers heading to the East Bay or Silicon Valley.
Start your search
The best preparation is to watch the market for a few weeks, so you learn what homes in each area really sell for. You can follow live listings, pending sales and recently sold homes, plus guides to more than 30 neighborhoods, to find the right place to buy a house in San Mateo.
