Moving From San Francisco to Marin: Why the Math Reversed in 2026

Key Takeaways

• San Francisco is now more expensive than Marin. The city’s median sale price reached $2.1 million in mid-2026, up 25% year over year. Marin’s median sits at roughly $1.8 million.
• The city’s bidding wars have become extraordinary. Homes selling more than $1 million over asking rose roughly 1,700% year over year, with 44 such sales in June alone against eight in the entire first half of 2025.
• Southern Marin is absorbing the first wave. Two Sausalito homes this spring drew five and seven offers, closing $800,000 and more than $1 million above asking.
• The Ross Valley is where the second wave lands. San Anselmo, Fairfax, and San Rafael all posted higher unit sales this spring on flat or softer medians. That combination is what a value window looks like before it closes.
• The effect arrives on a delay. Brokers watching both markets put the lag at roughly six months, placing the strongest wave of buyers moving from San Francisco to Marin in the fourth quarter of 2026.

The number that changed everything

For as long as I have worked in this market, and that is now twenty-five years, the calculation for a San Francisco family considering Marin ran one direction. You gained space, schools, and air. You paid for it in price, or at minimum in commute.

That calculation inverted this year.

San Francisco’s median sale price reached $2.1 million in mid-2026, a 25% increase year over year, against roughly 590 active listings countywide and about one month of supply. Marin’s median sits near $1.8 million. In other words, the county with the open space, the ferry, and the top-ranked schools is now the less expensive of the two. Consequently, moving from San Francisco to Marin has stopped being a lifestyle trade and started being a financial one.

I want to walk through what is actually happening, because the headline understates it, and because the most interesting part is not where buyers are landing first. It is where they are landing second.

What buying in San Francisco looks like right now

The city’s inventory fell roughly 30% year over year. As a result, competition has reached levels that surprise even people who lived through 2021.

According to reporting in The Real Deal this July, 144 San Francisco homes sold for more than $1 million over asking in the first half of 2026. Forty-four of those closed in June alone. The comparable figure for the entire first half of 2025 was eight. That is not a hot market. That is a market where the asking price has stopped carrying information.

One Cow Hollow property listed at $8 million and closed near double that figure in two weeks.

The driver is well understood by now. This cycle’s wealth is concentrated in San Francisco proper rather than the Peninsula, and it is arriving in liquid form. I wrote about that shift when the AI wealth wave first became visible in our numbers. What has changed since is scale. Santa Clara County prices actually declined about 5% over the same period. The money is not spreading across the Bay Area. It is concentrating in the city, and then it is spilling north.

Why buyers are moving from San Francisco to Marin

A San Francisco buyer who has lost three bidding wars arrives here with a specific profile. They are pre-approved or paying cash. They have a number in mind that has already been tested and exceeded twice. Above all, they are tired.

Marin offers that buyer something the city cannot: a market where a strong offer still wins.

The county median rose about 11% year over year to $1.8 million, with price per square foot near $958, up roughly 28% since December. Those are meaningful gains. However, set against the city’s 25% median increase, Marin reads as the disciplined choice. As one San Francisco broker put it in that same reporting: “There’s only one San Francisco, but plenty of second choices.”

Southern Marin is absorbing the first wave, which is unsurprising given the ferry. Two Sausalito results tell the story plainly. 18 Laurel Lane attracted five offers and closed at $4.6 million, roughly $800,000 above asking. 22 Filbert Avenue attracted seven offers and closed at $3.5 million, more than $1 million above asking. Both sold this spring.

Mill Valley, Tiburon, and Belvedere are named in the same reporting as the next destinations. That matches what I see in showings.

Where the second wave lands: the Ross Valley

This is the part of the story no one is writing about yet, and it is the part I would pay attention to.

Every migration of this kind moves in two stages. The first wave buys the obvious address. The second wave, arriving six to twelve months later, has watched the first wave bid $800,000 over asking in Sausalito and decides to look one valley inland. In Marin, that means San Anselmo, Fairfax, Ross, and the better pockets of San Rafael.

The second quarter numbers show that door is still open. San Anselmo’s median fell 13% to $1,720,000 even as unit sales rose 20%. Fairfax averages eased 3% while sales climbed 30%. San Rafael’s average price rose 14% on 15% more sales. Read those together and the picture is unmistakable: buyers are absorbing more homes in the Ross Valley than they did last year, and they are not yet paying a premium to do it.

That is what a value window looks like from the inside. It does not announce itself. It shows up as rising volume on flat prices, and it closes quietly.

I have spent the majority of my career in these towns. I have represented homes on Floribel, Carolina, Sunnyside, and Alder in San Anselmo, on Laurel Drive and Marinda in Fairfax, in Sleepy Hollow, and across the Civic Center and Terra Linda neighborhoods of San Rafael. Several of those houses I have now sold more than once, which is the part of this work I value most. So when I say the Ross Valley is where the next wave lands, it is not a forecast borrowed from a headline. It is a read on streets I know house by house.

What the top of the market is doing

The luxury tier tells a parallel story, and it is worth understanding even if you are not shopping at that level, because it sets the tone for everything beneath it.

Marin closed the second quarter with an average sale price of $2,582,207 across 706 single-family sales, up 11% and 16% respectively. Ross average prices rose 65%. Kentfield rose 45%. Belvedere’s median climbed 37%. Sellers countywide received an average of roughly 105% of asking, and more than half of single-family homes sold above list. Inventory ended June near 501 listings, down about 22% year over year. You can read the full breakdown in the Q2 report.

The trophy sales confirm it. 4 Blanding Lane in Belvedere listed at $13,750,000 and closed at $15,277,000 on May 11, about 11% above asking in twelve days, at $5,205 per square foot. That is the highest confirmed on-market sale in Marin this year. In Ross, 16 Sylvan Lane listed at $6,995,000 and closed at $9,000,000 on July 13, roughly 29% above asking, after seven days.

I have worked at this end of the market as well, including on Golden Gate Avenue in Belvedere, on Laurel Grove Avenue in Ross, on Centro West in Tiburon, and on Altamira in Kentfield. What I would tell you from that vantage point is that these results are not the whole picture.

The discipline the averages hide

Ten weeks before 16 Sylvan Lane sold 29% over asking, 80 Laurel Grove Avenue in the same town listed at $11,995,000 and closed at $10,500,000, about 12.5% below asking, after thirty days on market. Same town. Same quarter. Same buyer pool.

The pattern repeats across the county. 185 Gilmartin Drive in Tiburon, a 13,836-square-foot estate, finally closed on July 15 at $13,850,000 after nearly three years on the market and roughly 22% below its original asking price.

Countywide, homes that go under contract within thirty days achieve close to 105% of their original asking price. Homes that sit past 120 days achieve roughly 84%. On a Marin home, that spread is worth several hundred thousand dollars.

Therefore, the wave of buyers moving from San Francisco to Marin is not a reason to list casually. It is a reason to list correctly.

The timing detail most sellers are missing

Here is the most useful thing in this post, and it is a matter of calendar rather than sentiment.

David Cohen, a cofounder of a San Francisco brokerage watching both sides of the bridge, described the lag directly: “It usually takes about six months after the booms in San Francisco for the peripherals to really feel it.” He was more specific about what comes next. “People are about to start flocking to these peripheral markets, especially Marin.”

Six months from the city’s spring acceleration lands in the fourth quarter of this year.

There is a second calendar worth watching alongside it. A major technology listing in June created an estimated 4,400 new millionaires on standard 180-day lockups, which release around December, and another significant listing is anticipated this autumn. Newly liquid buyers do not shop the week their shares unlock. They begin looking well before.

Rates, meanwhile, have held steadier than most expected. The 30-year fixed averaged 6.58% in the Freddie Mac survey on July 23, modestly below where it stood a year ago. For the Marin luxury tier this matters less than it sounds, since most transactions above $1.25 million move to jumbo financing or cash regardless. Coldwell Banker Global Luxury research this year found all-cash purchases among luxury clients rose to 63%, up from 51%, and that international searches for United States property doubled in the first five months of 2026, with California leading every state.

What I would do now

If you are selling in southern or central Marin, the window ahead of you is genuinely favorable, and the fourth quarter looks stronger still. Use the intervening weeks. Buyers arriving from a city where they have already lost properties are decisive, but they are also comparing your home against very recent, very expensive alternatives. They will not renovate. Finished, staged, correctly priced homes are the ones drawing five and seven offers.

If you are selling in the Ross Valley, you are earlier in the cycle than Sausalito and Mill Valley, and that is an advantage rather than a disadvantage. Volume is already rising in your town. Price against this spring’s actual closings rather than last year’s expectations, and you will meet the second wave as it arrives rather than after it has settled.

If you are buying from San Francisco, you are not late, and you are not yet paying a premium for patience. What you should be doing is establishing your criteria and your relationships before autumn rather than after. The best properties in Belvedere, Tiburon, and Ross frequently trade privately, and a meaningful share never appears on the MLS at all. Access to those matters more than search alerts do.

If you own in Marin with no plans to move, the useful takeaway is that your position has strengthened for reasons that have nothing to do with Marin. That is worth understanding before you make decisions about renovating, refinancing, or holding.

Frequently Asked Questions

Is it cheaper to buy in Marin County than in San Francisco in 2026?

By median sale price, yes. San Francisco’s median reached approximately $2.1 million in mid-2026, up 25% year over year, while Marin County’s median was approximately $1.8 million. This reverses the historical relationship between the two markets.

Why are San Francisco buyers moving to Marin in 2026?

San Francisco inventory fell roughly 30% year over year to about 590 active listings, producing extreme competition. Homes selling more than $1 million over asking rose approximately 1,700% year over year. Many buyers who have repeatedly lost properties in the city are now looking north, where a strong offer is still competitive.

Which Marin towns are San Francisco buyers choosing?

Southern Marin is absorbing the first wave, led by Sausalito given its ferry access, followed by Mill Valley, Tiburon, and Belvedere. The second wave typically moves inland to the Ross Valley, meaning San Anselmo, Fairfax, Ross, and San Rafael, where prices remain flatter even as sales volume rises.

Where is the best value in Marin County right now?

The Ross Valley. In the second quarter of 2026, San Anselmo’s median fell 13% while unit sales rose 20%, and Fairfax averages eased 3% while sales rose 30%. Rising volume on flat pricing is the signature of a value window.

How competitive is the Marin market right now?

Marin sellers received an average of roughly 105% of asking price in the second quarter of 2026, and more than half of single-family homes sold above list. Inventory stood near 501 listings in June, down about 22% year over year.

When is the best time to sell a Marin home in 2026?

Brokers who track both markets place the lag between a San Francisco surge and its Marin effect at roughly six months, which points to the fourth quarter of 2026. Homes prepared and priced correctly ahead of that window are best positioned.

Do Marin luxury homes still sell above asking price?

Frequently, though not universally. In 2026, one Ross home sold 29% above asking in seven days while another in the same town closed 12.5% below asking. Preparation, condition, and pricing strategy determine the outcome more than market conditions do.
