Pull up San Carlos home prices on three different sites this week and you will get three different answers, and they will not even agree on direction. One source shows the median climbing by double digits. Another shows it falling. A third falls too, just by less. Same city. Overlapping months. Numbers moving in opposite directions at the same time.
That is not a glitch. It is a byproduct of method, and untangling it tells a San Carlos buyer more about where to shop than the headline number ever will.
Over the three months ending May 2026, San Carlos home prices were up 10.8 percent compared to the same period a year earlier, with a median sold price of $2.7 million, according to Redfin. That figure comes from actual closed transactions in a rolling three month window, so it moves with whatever mix of homes happened to sell.
Zillow's home value index told a different story for the same stretch. As of May 31, 2026, the typical home value across San Carlos sat at $2,161,366, down 7.2 percent over the past year. That index is not built from a season's worth of closings. It estimates value across the entire housing stock, including homes that have not changed hands in years, which pulls the number toward the city's older, smaller inventory rather than whatever happens to be trading right now.
MLSListings, drawing on closed single family transactions for June 2026 alone, put the median sold price at $2,625,000, down 5.4 percent year over year, with a median price per square foot of $1,591 and homes selling at 104 percent of list price on average.
| Source | Reporting window | Headline figure | Year over year | What it actually measures |
|---|---|---|---|---|
| Redfin | 3 months ending May 2026 | $2.7M median sold price | +10.8% | Recent closed transactions, all property mix |
| Zillow (ZHVI) | As of May 31, 2026 | $2,161,366 typical value | -7.2% | Modeled value across the full housing stock |
| MLSListings | June 2026 | $2,625,000 median sold price | -5.4% | One month of closed single family MLS sales |
Three legitimate methods, three legitimate numbers, and none of them wrong. The gap between them is not noise to average away. It is a signal that the mix of homes closing right now looks different from the city's housing stock as a whole, and that difference has a specific address.
Ask most people which San Carlos neighborhood carries the city's top address and White Oaks comes up first. Tree lined streets, a walk to downtown, a run of restored prewar homes. That reputation is real and it still drives sales volume. But price per square foot has told a different story since the early 2010s, and it has not flipped back.
Howard Park, a flatter grid of postwar ranch houses a few blocks from Burton Park, passed White Oaks on price per square foot more than a decade ago and has held that lead since. In March 2026, Howard Park's median sale price per square foot ran roughly $1,400, up 21.1 percent year over year, with homes averaging 8 days on the market, down from 11 days the prior March.
The neighborhood everyone names first when asked about San Carlos's best address is not the one setting the city's price ceiling.
That matters for anyone comparing two San Carlos neighborhoods off a portal search, because a search that sorts by reputation and a search that sorts by dollar per square foot will point in different directions.
Howard Park's housing stock is largely postwar ranch style on lots around 5,000 square feet, often with attached garages, sitting close enough to Burton Park and the Laurel Street corridor to walk both. That proximity is doing real work in the pricing.
White Oaks and the adjoining Oak Park sit just north and south of Belmont Avenue and are frequently reported together in MLS data as a single area. The stock here skews toward smaller prewar bungalows on tighter lots, which is part of why price per square foot in this area can run high even when total sale price does not always lead the city. That single detail, that two named neighborhoods sometimes get folded into one reporting bucket, is itself a small example of why a citywide number needs unpacking before you compare it to a specific street.
Cordilleras Heights and the western foothills sit at the other end of the spectrum: larger hillside lots, more separation between homes, and a different set of transaction friction. Hillside lots here face additional geotechnical review under California building code, and parcels with slope conditions may require soils reports during the inspection period, a detail worth knowing before you fall for the extra acreage.
Proximity to downtown is not a static advantage. It is compounding, because downtown San Carlos is in the middle of a multi year build out that is adding reasons to walk there.
The city's Downtown Specific Plan cleared its second reading on January 26, 2026 and took effect February 25, 2026, laying out two decades of goals for growth around Laurel Street. Construction on the Harrington Park Refresh began April 6, 2026, with completion expected in early 2027, and includes a new plaza, public seating, and a rain garden woven into the park's redesign.
The storefronts have turned over alongside the construction. Christian Conte, who already owned Drakes on Laurel Street, took the former Sneakers American Grill space and opened Highlands Sports Bar & Grill. Elia Restaurant, run by Fatih Ulas, moved into the former Taurus space, one of several Bay Area locations Ulas operates beyond San Carlos. The street's calendar has not slowed either. The Sunday farmers market runs year round, Hometown Days has filled Burton Park every May since 1979, and the Art and Wine Faire returns each October drawing more than 40,000 visitors over a single weekend.
None of that foot traffic is evenly distributed across San Carlos. It concentrates around Laurel Street, and Howard Park sits closer to that concentration than most of the neighborhoods competing with it on price.
Each of the three numbers above is useful for a different decision. Redfin's rolling sold median is the closest thing to what a buyer's agent will pull for comps on an active offer, since it reflects what actually closed recently. Zillow's broader index works better as a sanity check against overpaying for a hot pocket, since it accounts for the full stock rather than this month's mix. MLSListings' single month figures, including that 0.5 months of inventory reading in June 2026, tell you how tight supply is right now rather than over a season, which matters most when you are deciding how aggressively to move on a specific listing.
None of this means every San Carlos listing is winning a bidding war. Earlier in 2026 the pace of new listings outran the pace of homes going under contract for a stretch, and some overpriced homes sat long enough to come off the market and relist later. A tight neighborhood average does not guarantee a fast sale on every address inside it. Pricing discipline still separates the homes that move in eight days from the ones that sit.
Why do Zillow and Redfin show different numbers for the same city? They are built from different inputs. Redfin's figures come from a rolling window of actual closed sales, so they shift with whatever homes happened to trade. Zillow's index estimates value across the entire housing stock, including homes that have not sold recently, which tends to smooth out short term swings toward the market's older, broader base.
Is Howard Park still considered San Carlos's more affordable alternative to White Oaks? Not on a price per square foot basis. That was the relationship for decades, but the lead switched in Howard Park's favor in the early 2010s and has held since, even though White Oaks still draws a higher volume of overall sales.
Does hillside lot size in Cordilleras Heights offset the extra review requirements? That depends on the buyer's priorities more than the market data. The larger lots come with real trade offs, including geotechnical review and possible soils reports for sloped parcels during inspection, so the acreage is not free of friction even when it is priced attractively per square foot.
