Mill Valley, CA Housing Market 2026: Median Home Price, Last 12 Months

If you invest in or around Mill Valley, the number that matters is what homes actually close for, not what sellers are asking. Here is what Mill Valley sale prices look like right now, built from the closings Resideline tracked over the last 12 months, as of September 2026.

The snapshot

• •Closings tracked, last 12 months: 210
• •Median sold price, last 12 months: $2,300,000
• •Median sold $/sqft, last 12 months: $1,013

What the numbers say

Resideline tracked 210 closed sales in Mill Valley over the last 12 months, with a median closing price of $2,300,000. That median is the midpoint of what buyers actually paid, not what sellers hoped to get, which is why it moves differently from the asking prices you see on listing sites. The middle half of those sales closed between $1,400,000 and $3,350,000. That spread matters more than the headline median: where a specific property sits inside it decides whether the citywide number helps you or misleads you. These are the closings Resideline tracks and may differ from complete county or municipal records. Across the 206 closings with usable living area, the middle half sold between $821 and $1,383 per square foot.

The Mill Valley angle

Mill Valley is a market where the median needs heavy qualification. Resideline tracked 210 closings over the last 12 months at a median closed sale price of $2,300,000, but the middle half of sales stretched from $1,400,000 to $3,350,000, wider than most spreads we track. The band also runs dramatically further above the median than below it, so the high end pulls away from the midpoint in very large increments. Read together, the message is that no citywide figure prices a specific property here: two ordinary closings can sit enormously far apart while both being unremarkable sales. Ground any estimate in closed sales matched tightly to the subject, and keep $2,300,000 as context only.

From market read to offer price

A market read is the backdrop. The decision still comes down to one property and one number: what it is actually worth and what you should pay. Every Resideline report opens with this same market snapshot for the subject's exact ZIP code, then gives you the property's value, the sold comps behind it, and a market rent estimate. Pricing a specific deal? The free ARV calculator and rental property calculator run the numbers in about a minute.

And we show our work. Every estimate is frozen while the home is for sale and graded against the real closing price after it sells. See the live accuracy dashboard for the receipts, or read how the Area Market Snapshot works.

Run any Mill Valley address through Resideline and you will see the local market and the property's value together, in one report.

The local market statistics in this report are calculated from closed sales tracked by Resideline. Transaction coverage may differ from complete county or municipal records.

Every local market figure on this page is computed from closed sales Resideline tracked in Mill Valley over the last 12 months, and is refreshed when the data is. The closings we track within the Mill Valley city limits are not limited to listing-service sales: they also include foreclosure deeds, estate and family transfers, and other off-market sales that portal medians exclude, which is why 17% of the 210 closings in this window never appeared on a listing service, and the median of MLS-listed sales alone was $2,200,000.
