Straight numbers on what homes in Alta Sierra are actually selling for, how fast they are moving, and how much is on the market, pulled from the MetroList MLS and refreshed every month.
The median sold price for a single-family home in Alta Sierra was $483,000 in September 2026, down 18.7% from $594,000 in August but up 7.3% from $450,000 in September 2025. On a per-square-foot basis, homes averaged $263 per square foot, down from $309 in August and $275 in September 2025.
Twelve homes closed in September. At that sample size the median describes which twelve houses sold far more than it describes what Alta Sierra is worth, and a swing of this size between two consecutive months is ordinary here rather than alarming. August skewed high, September skewed low. The year-over-year comparison is the steadier one, and it is up.
Homes that closed in September 2026 averaged 68 days on market, up from 43 days in August and above the 52 days recorded in September 2025.
That is a real slowdown rather than a rounding artifact, though with twelve closings a couple of long-sitting listings can move the average on their own. The three-month average, 61 days across July, August and September, is the steadier figure. The swing from 72 days in July to 43 in August and back to 68 in September is a good illustration of why one month on its own says very little here.
Alta Sierra sits at 3.0 months of supply, down from 3.4 in August and 3.2 a year ago. Months of supply measures how long it would take to sell every home currently listed at the current pace of sales.
The conventional dividing line puts anything under roughly six months in seller’s-market territory, so by that measure Alta Sierra still leans toward sellers, and supply is slightly tighter than it was in August. What softened in September was everything else: homes took longer to sell and closed a little further below their original asking prices. A seller-leaning market with patient buyers in it is the fairest way to describe it.
Sales in September closed at an average of 99% of final list price and 95% of original list price. In August those figures were 101% and 97%.
Both eased slightly, which fits the longer days on market. Sellers are still landing within a few percent of where they started, so this is a market asking for realistic pricing rather than one punishing it. The five-point gap to original list suggests a reduction somewhere along the way on a fair share of sales.
There were 36 active listings in Alta Sierra at the end of September 2026, down from 37 in August and down about 5% from the 38 on the market in September 2025.
Inventory has barely moved: 36 now, 37 in August and 38 at the same point last year. Seventeen new listings came on in September against twelve closings, so supply held roughly level. For a neighborhood this size that steadiness matters more than any single month’s median.
The numbers above tell you what the market is doing. These go into what it means for a specific house, and what living here is actually like.

Figures cover single-family homes in the Alta Sierra area (MLS area 13101) and are drawn from the MetroList MLS, based on 12 closed sales in September 2026. Information is deemed reliable but not guaranteed. Alta Sierra is a small enough market that a single month’s median moves sharply on which homes happened to close, so these figures describe the market in aggregate and are not an appraisal or a valuation of any individual home.
