Choose San Carlos if a walkable downtown and the San Carlos School District top your list; choose Belmont if hillside views, open space, and often more house or lot for the same budget matter more. Most addresses in both towns feed Carlmont High and the two sit five minutes apart. In September 2026, San Carlos single-family homes closed at a $2.8 million median and 107.5% of list price on 19 sales; Belmont at $2.7 million and 102.1% on 21.

Five minutes apart on El Camino, and closer in price than most people expect. Here is where they actually differ.
| September 2026 | San Carlos | Belmont |
|---|---|---|
| The Market · Single-Family Homes | ||
| Median sale price | $2.8M | $2.7M |
| Sale vs. list price | 107.5% | 102.1% |
| Average days on market | 18 | 26 |
| Months of inventory | 1.0 | 0.8 |
| Homes sold | 19 | 21 |
| Daily Life | ||
| Downtown | Laurel Street — a true pedestrian main street with independent restaurants and a Sunday farmers’ market. | No marquee downtown. 19-acre Twin Pines Park is the town square. |
| Terrain | Level flats in Howard Park and Beverly Terrace, rising to White Oaks and Brittan Heights in the western hills. | Winding hill streets, split-levels, and Bay views up top; level streets in Sterling Downs and Hallmark. |
| Outdoors | Tree-lined streets and a low-key, small-town pace close to downtown. | The Waterdog Lake trails, close enough for an after-work hike. |
| Size | 5.5 square miles | 4.6 square miles |
| Schools | ||
| K-8 | San Carlos School District | Belmont-Redwood Shores Elementary School District |
| High school | Carlmont High for most neighborhoods, or Sequoia High · Sequoia Union district | Carlmont High, in town · Sequoia Union district |
| Getting Around | ||
| To San Francisco | About 25 miles; Caltrain station on El Camino | About 24 miles; Caltrain station in town |
| Watch for | U.S. 101 and I-280 are both about five minutes away. | Ralston Avenue is the main east-west route and backs up at peak hours. |
| Before You Buy | ||
| The homework | Much of the housing is older; check lot, parking, and foundation conditions, especially on hill streets. | On slopes, drainage, retaining walls, decks, and foundations matter more than the paint. |
Source: MLSListings Inc., pulled from MLSListings Matrix by Elaine Li — single-family homes closed in September 2026; months of inventory is active listings on the pull date divided by the month’s sales. With about 20 sales a month in each town, the median moves with whichever homes happen to close; sale-to-list and days on market are the steadier signals. Based on information from MLSListings, Inc.; deemed reliable but not guaranteed. School assignment follows the address — confirm it with the district.
Both towns sit in the Sequoia Union High School District, and most addresses in each are assigned to Carlmont High. Both have their own Caltrain station, both reach U.S. 101 and I-280 in minutes, and both sat in a clear seller’s market in September 2026, with single-family homes closing above list price and less than two months of supply.
So the choice is rarely about which market is easier to buy in. It is about the daily texture: a walkable downtown and flatter streets in San Carlos, or the hills, the trails, and the views in Belmont.
I live in San Carlos, my family spends a lot of time in Belmont, and I’m on Ralston constantly. People like to frame Belmont as the cheaper version of its neighbor. I don’t. Belmont’s median is lower, but it still sells over asking — what you are really choosing between is a downtown and a hillside.
If your ideal Saturday starts on foot, with coffee, the farmers’ market, and errands on Laurel, start in San Carlos. If it starts on a trail or on a deck with a view, start in Belmont. Then let the specific address decide.

At the median, yes: Belmont single-family homes sold for a median of $2.72 million in September 2026, vs. $2.75 million in San Carlos. But Belmont still closed at 102.1% of list price, so it is not a bargain market. Buyers who tour both usually find more house or more lot for the money in Belmont rather than the same home for less.
Largely, yes. Both towns are in the Sequoia Union High School District, and most addresses in each are assigned to Carlmont High; some San Carlos addresses go to Sequoia High instead. Attendance areas can shift, so confirm the assignment for the specific address before you buy.
San Carlos. Laurel Street is a true pedestrian main street with independent restaurants, coffee, and a Sunday farmers’ market. Belmont has no marquee downtown; its gathering place is 19-acre Twin Pines Park, and Laurel Street is about five minutes away.
They are close. Belmont is about 24 miles from San Francisco and San Carlos about 25; both have Caltrain stations and reach U.S. 101 and I-280 in minutes. In Belmont, test how a home connects to Ralston Avenue, which backs up at peak hours.
Tell me what matters most — the downtown, the hills, the school, the commute — and I’ll tell you honestly which one I’d look at first.
