Blog > Los Altos Home Appreciation: What the Same Houses Resold For (2026)
What did Los Altos houses actually gain? Not a city average, but the same house, sold twice. We matched 126 Los Altos houses that sold in the last 24 months to their previous sale since 2012. Of those, 86 were about the same size both times, so the gain is the market, not an addition. The median one sold for 54% more than its owner paid, after about 7.4 years: about 6.1% a year. Here’s the breakdown by purchase year, the houses that grew, and how often owners sold for less. We’re the Property Nerds, so the numbers come from real sales.
The short answer
- The typical same-size house resold for 54% more than its last price, about 6.1% a year over a median 7.4 years.
- Bought in 2012–2013: up 117%. Bought in 2020–2022: up 33%.
- Sold for less than paid: 3 of 86 same-size houses.
- Expanded or rebuilt: 27 houses came back at least 25% bigger and sold for a median 136% more than their earlier price.

By the year the seller bought
Same-size houses resold in the last 24 months (October 28, 2024 to October 27, 2026), by when the seller had bought:
| Bought | Houses | Median price paid | Median resale | Median gain | Per year | Years held | Sold for less |
|---|---|---|---|---|---|---|---|
| 2012–2013 | 8 | $1.83M | $4.25M | +117% | 6.7% | 12.6 | 0 |
| 2014–2016 | 21 | $2.77M | $5.1M | +78% | 6% | 10.1 | 0 |
| 2017–2019 | 28 | $3.4M | $5.35M | +48% | 5.5% | 7.4 | 0 |
| 2020–2022 | 21 | $3.5M | $4.5M | +33% | 6.6% | 4.8 | 3 |
Small groups swing more, so read a row with only a dozen or so houses as a rough guide.
Houses that came back bigger
27 of the resold houses had at least 25% more living area the second time, from a median 1,740 to 3,620 square feet: additions, second stories and rebuilds. They sold for a median 136% more than their earlier price. That gain includes the cost of the work, which these sales don’t show, so it isn’t profit.
Reading it right
- These are prices, not profits. Selling costs, the cost of any updates, and the mortgage interest and taxes paid along the way all come out of the gain.
- Not adjusted for inflation. A dollar in 2012 bought more than a dollar today.
- Same size isn’t same condition. Many owners remodel inside the same footprint, and a dated house resold as-is can trail its neighbors.
- Sellers choose when to sell. Owners who would have sold at a loss often wait, so resales lean toward gains.
What it means for you
- Selling: your gain is likely large if you bought before 2017. Check the home-sale tax exclusion before you list, and if you’re 55 or older, Prop 19 for your next home.
- Buying: recent buyers’ gains were smaller, and 3 of the 86 sold for less than they paid. Plan to stay long enough for the costs of buying and selling to wash out.

The long run and the last year
Repeat sales show what owners gained over years. The year-to-year medians show the short run: the median Los Altos house sold for $4.81M in the 12 months before last and $4.9M in the last 12 months, up 1.8%. A change in the median also reflects which houses happened to sell, so it swings more than any one house does.
Recent buyers are the ones to watch. The 21 same-size houses bought in 2020 to 2022 and resold in the last 24 months gained a median 33% over about 4.8 years, 6.6% a year, and 3 sold for less than the owner paid. Buying and selling costs can take a large share of a gain that size.
Questions we get
How much have Los Altos homes appreciated?
Houses that resold in the last 24 months at about the same size gained a median 54% over their earlier price, about 6.1% a year over 7.4 years.
Do Los Altos homes ever sell for less than the owner paid?
Rarely in this window: 3 of 86 same-size resales.
How long do owners keep a house before selling?
Among these resales, a median of 7.4 years. That counts only houses that sold twice since 2012, so longtime owners aren’t in it.
How we counted
Every Los Altos house sale in the last 24 months (October 28, 2024 to October 27, 2026) matched to its previous sale by address (house number, street and unit), where the earlier sale was in 2012 or later and at least a year before. Both are closed sales reported to the MLS and read through the IDX feeds that power our home search, one record per sale with a usable living area and map position, the same rules as our city price posts. Houses are MLS property type “single family home”; condos include townhomes. “About the same size” means living area within 5% both times; “bigger” means at least 25% more. Gains are the median of each house’s own price change; “per year” is the median annualized rate. Past sales aren’t a forecast or the value of any one home, and nothing here is financial, tax or legal advice.
