Pull up Larkspur's numbers on a home search site in December and you'd have seen a median sale price near $1.4 million. Pull the same search in March and the median had jumped to just over $2 million. Nothing about Larkspur changed in those three months. The bridge to the freeway didn't move. The schools didn't improve. What changed was which dozen or so houses happened to close escrow.
That is the thing nobody tells you when you start comparing Marin towns by their headline price: some of these markets are so small that the "median" is barely a statistic at all. It's closer to a list of recent sales with a middle one circled.
Why a Handful of Closings Swings the Whole Number
In November 2025, Redfin recorded a Larkspur median sale price of $1.4 million, down 31.5 percent from the year before, with homes taking an average of 47 days to sell compared with 27 days the prior year. Eleven homes sold that month, up from six a year earlier.
By February 2026, the picture had flipped. Redfin's data for that month showed a Larkspur median sale price of $2.074 million, well above both the Marin County median of $1.357 million and San Rafael's $1.34 million for the same period. Homes were selling in an average of 13 days, at 104.8 percent of list price, with half of all sales closing above asking.
A median swinging by roughly 48 percent in a single quarter is not a story about value. It's a story about sample size. When only eleven or so homes close in a given month, one large estate sale or one modest fixer can move the reported median by hundreds of thousands of dollars without a single existing homeowner in town gaining or losing a dollar of equity. Larkspur isn't lying to you when it reports these numbers. It's just too small a dataset to behave like the statistics you're used to reading about bigger markets.
What San Rafael's Numbers Reveal by Contrast
Put Larkspur next to its larger neighbor and the difference in market depth becomes obvious. In the same February 2026 window, Realtor.com counted just 14 homes for sale in Larkspur, with a median of 24 days on market. San Rafael, the next town over, had 154 homes for sale and a median of 32 days on market.
That gap matters more than either median price. San Rafael has enough transactions flowing through it in a given month that its median behaves the way a median is supposed to behave, smoothing out the outliers. Larkspur's entire active inventory in that snapshot could fit in a single open house weekend. There is no smoothing effect on a pool that small. Every closing is a headline.
The List Price vs. Sold Price Trap
There's a second trap layered on top of the small-sample problem, and it catches people who think they're comparing apples to apples. By June 2026, Movoto reported a Larkspur median list price of $1.53 million at $859 per square foot, with homes spending a median of 41 days on the market, unchanged from a year earlier.
Read quickly, that $1.53 million looks like it contradicts the $2.074 million figure from February. It doesn't, because the two numbers aren't measuring the same thing. One is a median of homes that closed. The other is a median of homes currently asking. A seller can list at $1.53 million and still receive $1.8 million once the offers come in, and that outcome would show up as a sold price nowhere near the asking figure that a portal displayed the week before.
When you're stacking one town's numbers against another's, the first question isn't "which town is more expensive." It's "am I even comparing the same kind of number, from the same kind of window."
Why Buyers Still Move Fast Despite the Noise
If the headline price is this unstable, why does anything in Larkspur sell in 13 to 24 days at or above asking? Because a meaningful share of Larkspur's buyer pool isn't shopping Marin broadly. They're shopping for a specific kind of commute, and Larkspur is the only town in Marin that offers it.
Larkspur is the only Marin community served by both a Golden Gate Ferry terminal and a SMART rail station. The two aren't even in the same spot: the SMART Larkspur station sits a 12-minute walk from the ferry terminal, and for anyone who doesn't want to make that walk, a bright orange shuttle meets every southbound train within about 10 minutes to close the gap. On game days, the Golden Gate Ferry runs a dedicated Giants Ferry straight from the Larkspur terminal to Oracle Park, departing roughly an hour and forty-five minutes before first pitch, with fares at $16.50 each way and children four and under riding free.
That combination narrows the buyer pool to something more specific than "wants to live in Marin." It's "wants rail and ferry access from the same neighborhood," and there is exactly one place in the county that offers it. A narrow, motivated pool competing over a genuinely small number of listings explains the fast sales and strong sale-to-list ratios far better than any single median price does.
The Fixed Points Underneath the Volatility
The other reason Larkspur holds buyer interest through a wobbly price chart is that the parts of the town people are actually buying into haven't changed. Downtown Larkspur, centered on Magnolia Avenue, is listed on the National Register of Historic Places, and the character that comes with that designation isn't something a rough quarter of sales data can erode. The Art Deco Lark Theater received the 2025 Spirit of Marin award under director Ellie Mednick for its contributions to the local community, and Chef Roland Passot's Left Bank Brasserie has been serving the same neighborhood since 1994.
None of that shows up in a median sale price. All of it shows up in why a buyer who loses one bidding war in Larkspur tends to come back for the next listing instead of widening their search to a cheaper town with a similar price tag.
What This Means If You're Comparing Towns by Price
If Larkspur is on your shortlist alongside other Marin towns, the median alone will mislead you more often than it helps. A few adjustments make the comparison useful instead of misleading.
- Check what window the number covers. A single month's median in a low-volume town can swing on one or two sales, so a trailing three or six month figure tells you more than a single snapshot.
- Confirm whether you're looking at a sold price or a list price. They answer different questions, and portals don't always make the distinction obvious.
- Look at the total count of active listings before you trust any median built from that pool. Realtor.com's February 2026 count of 14 active Larkspur listings is a reminder that a "market" this size doesn't behave like a market with hundreds of active listings.
- Weight days on market and sale-to-list ratio more heavily than the median price itself. Those figures move less erratically and tell you more about current competition.
- If dual transit access matters to your daily life, treat that as a standing feature of the town rather than something priced into any single quarter's numbers.
A Few Questions Worth Asking Before You Compare
Why did Larkspur's median price jump so much between late 2025 and early 2026? Because so few homes close in Larkspur in a given month that the mix of properties sold, not a shift in underlying value, drives most of the swing. Redfin's data went from a $1.4 million median in November 2025 to $2.074 million in February 2026 largely because different kinds of homes happened to close in each window.
How many homes are usually for sale in Larkspur at once? Realtor.com's February 2026 snapshot counted 14 active listings, compared with 154 in neighboring San Rafael during the same period. That is a thin pool even by Marin standards, and it means any median drawn from it should be treated cautiously.
Does the ferry and rail combination actually affect price, or is it just a nice amenity? It shapes who is bidding. A buyer pool narrowed to people who specifically want both Golden Gate Ferry and SMART rail access from one address helps explain why homes sold in an average of 13 days at 104.8 percent of list in February 2026, even while the headline median bounced around underneath them.
