The rally broadened this quarter
In the second quarter, the top of the Marin market pulled away from everything beneath it. This summer, the rest of the market began to follow. Between July and September, 553 single-family homes sold across Marin County, up 18% from the same quarter last year. The average sale price reached $2,380,667, up 9%. The county median rose 7%, to $1,760,000.
That median figure is the one I would watch. In the spring, the median rose just 3% while the average rose 11%, a sign that the most expensive homes were doing the lifting. This quarter the gap narrowed. Gains reached deeper into the market, and the towns that sell the most homes were the ones that moved the most.

Inside the Marin luxury market report Q3 2026: where the gains came from
San Rafael was the quarter’s engine. The town sold 145 single-family homes, up 42% year over year, and its median rose 18% to $1,651,000 while the average rose 14% to $1,855,130. When the county’s largest market moves on both price and volume at once, it lifts the whole county with it. Novato told a similar story on volume, with 119 sales, up 38%, and modest price gains.
At the top, Belvedere averaged $7,617,846, up 28%, with a median of $6,300,000 and unit sales up 86%. Kentfield rose 21% on both average and median, to $4,511,579 and $3,500,000. Ross averaged $6,206,429, up 14%, with its median up 18% to $3,895,000. Tiburon’s average rose 9% to $4,343,000 on 35% more sales.
Greenbrae posted the most dramatic figures on the table: a median of $3,350,000, up 94%, and an average up 66%. I would read that carefully. Nine homes sold in Greenbrae this quarter, so a small number of larger homes can move the percentages a long way.

Two reading notes. First, small towns produce volatile percentages. Greenbrae moved 94% on nine sales and Ross 18% on seven, so a few closings carry real weight. Second, days on market varied widely. Greenbrae homes sold in 20 days and Tiburon in 24, while Fairfax averaged 49 and Belvedere 45.
Where the market paused
Not every town rose, and the softer results are worth reading closely. Corte Madera’s average fell 8%, although its median still rose 3%. Larkspur’s median slipped 11% even as its sales rose 43%. Tiburon’s median eased 7% while its average climbed 9%. Sausalito was flat on average and down 3% on median, and Mill Valley held essentially level.
I would read most of this as mix rather than weakness. When a town sells 43% more homes, as Larkspur did, the median reflects which homes traded as much as what they were worth. Fairfax is the exception worth noting: sales fell 38% and homes took 49 days on average, the slowest pace in the county.
What Q3 means for sellers
If you own in San Rafael or Novato, buyers were active in numbers this quarter, and in San Rafael they paid meaningfully more than a year ago. If you have been waiting for the right moment, the data suggests your buyer pool is deep.
In the luxury corridor, from Belvedere and Tiburon through Ross and Kentfield, prices held or rose, but homes took between 24 and 45 days to sell. Preparation and pricing still separate a quick sale from a long one. At this level, buyers expect a finished home and a price that reflects the town’s actual third-quarter data.
What Q3 means for buyers
For buyers under $2 million, activity rose this quarter. San Rafael and Novato closed far more sales than a year ago, so being prepared to act quickly matters more than it did in the spring.
For buyers in Larkspur, Tiburon, Sausalito, and Mill Valley, flat or softer medians offer room to negotiate on the right home. In Fairfax, slower sales mean more time to decide and more leverage once you do.
