5 Silicon Valley Housing Market Numbers That Actually Matter in 2026
Real estate headlines love one number: Home prices are up.
Or: Home prices are down.
That can be interesting.
It is rarely enough to make a good real estate decision.
If you are buying or selling a home in Silicon Valley, I would rather know five things:
What are comparable homes actually selling for?
How much inventory is available?
How quickly are homes selling?
How close are sale prices to asking prices?
How often are sellers reducing their prices?
Together, those numbers tell us much more about buyer competition, seller leverage, pricing, and negotiation than one headline about home values.
As of September 2026, the latest complete monthly data is for August. For Santa Clara County single-family homes, MLSListings reported a median sale price of $1.85 million, 1.5 months of inventory, a 12-day median market time, and a 103% sale-to-list ratio.
Those four numbers already tell a more useful story than “prices are down 1.7% from last year.”
Here are the five market numbers I would actually watch.
1. Median Sale Price: What Are Buyers Actually Paying?
For Santa Clara County single-family homes, the August 2026 median sale price was $1.85 million, down 1.7% from August 2025.
The key word is median.
Half of the homes sold above that price and half sold below it.
It does not mean a particular Willow Glen home is worth $1.85 million.
It also does not mean every Santa Clara County homeowner's property value fell 1.7%.
The mix of homes sold changes every month.
If more $4 million Palo Alto and Los Gatos homes close one month, the county median may rise. If more lower-priced homes or condos close the next month, the median may fall even if individual neighborhoods have barely changed.
How buyers should use median sale price
Use it to understand the broad price environment and direction of the market.
Then narrow quickly.
If you are buying in Willow Glen, compare Willow Glen sales.
If you are looking at a 1,700-square-foot ranch on a 7,000-square-foot lot, compare it with similar homes rather than the entire county.
How sellers should use it
Do not price your home by applying a countywide percentage change to last year's value.
Your home's value depends much more on:
Exact location
Lot
Square footage
Condition
Floor plan
Renovation quality
Recent comparable sales
Current competition
Market trends tell us about the environment. Comparable sales tell us much more about the property.
2. Months of Inventory: How Much Choice Do Buyers Have?
This may be one of the most useful numbers that gets the least attention.
Months of inventory measures the relationship between available homes and the current pace of sales.
In August 2026, Santa Clara County had 1.5 months of inventory for single-family homes. MLSListings also reported 1,002 active single-family listings and 638 closed sales during the month.
That is still a relatively limited supply.
But here is where the statistic gets particularly interesting.
For condos and townhomes, Santa Clara County had 3.1 months of inventory in the same month.
Same county.
Different market.
Why inventory matters to buyers
Lower inventory can mean:
Fewer alternatives
More competition for well-positioned homes
Less time to decide on attractive new listings
Greater possibility of multiple offers
Higher inventory can give buyers:
More properties to compare
More time
More negotiating opportunities
Greater ability to walk away and consider another home
Why inventory matters to sellers
Inventory tells you how much competition your home will face.
If there are very few similar properties for sale, buyers may have limited alternatives.
If several comparable homes are available, your pricing and presentation become even more important.
This is why I would rather know the inventory for your property type and neighborhood than hear someone say broadly that Silicon Valley is a seller's market or buyer's market.
3. Days on Market: How Quickly Is the Market Responding?
Santa Clara County single-family homes sold in a median of 12 days in August 2026.
Condos and townhomes took a median of 26 days.
Again, two very different markets inside the same county.
Days on market helps answer a practical question:
How quickly are buyers making decisions?
For buyers
If desirable comparable homes are consistently selling within one or two weeks, you probably need your financing, disclosures review, and decision-making process ready before the right property appears.
That does not mean rushing into a home you do not understand.
It means doing your preparation early.
For sellers
Market time provides feedback.
If comparable homes are selling in 10 to 15 days and yours has been available for 40 days, I want to understand why.
Possibilities include:
Price
Condition
Location
Lot
Floor plan
Presentation
New competition
Longer days on market do not automatically mean something is wrong with a home.
But they are information.
Median versus average matters here too
Santa Clara County single-family homes had a 12-day median market time but a 26-day average in August.
That gap tells us some properties remained available much longer than the typical sale.
So when someone says, “Homes are selling in 12 days,” remember:
Some are. Some are not.
4. Sale-to-List Ratio: How Does the Final Price Compare With Asking?
This is another number buyers and sellers frequently misunderstand.
Santa Clara County single-family homes had a 103% sale-to-list ratio in August 2026. Condos and townhomes were at 100%.
At first glance, that sounds like single-family homes were “worth 3% more than asking.”
Not necessarily.
The list price is chosen as part of the seller's marketing strategy.
Imagine two homes that ultimately sell for $2 million.
One is listed at $1.8 million and receives several offers.
The other is listed at $2.1 million and negotiates down.
The first sells substantially over asking.
The second sells below asking.
They still produced the same sale price.
Why this number matters anyway
Over many transactions, the sale-to-list ratio can help show how buyers are responding to asking prices.
A high ratio may indicate:
Competitive bidding
Strategic pricing below expected market value
Strong demand for certain property types
Limited inventory
A lower ratio may indicate:
Greater negotiation
More ambitious list pricing
Increasing inventory
Softer demand
But never use “percentage over asking” by itself to decide whether a buyer overpaid or a seller achieved an exceptional result.
Compare the final sale price with the property's market value, not just its list price.
5. Price Reductions: Are Sellers Having To Adjust?
Price reductions can tell us something that median prices do not:
Are initial seller expectations matching what buyers are willing to pay?
Redfin reported that 16.5% of Santa Clara County listings had a price drop in August 2026. At the same time, the countywide sale-to-list ratio for all home types was about 102%.
Those two statistics can coexist.
Some homes generate immediate competition.
Others need a pricing adjustment.
That is a good description of many Silicon Valley submarkets right now.
What buyers should watch
A price reduction can create an opportunity.
But do not assume:
Price reduced = bargain.
Ask whether the new price makes sense relative to comparable sales and competing listings.
A house reduced from $2.3 million to $2.1 million could still be overpriced if the market supports $2 million.
Another property reduced by only $50,000 might suddenly become very compelling.
What sellers should watch
If your property is receiving showings but no offers, or similar homes are going pending while yours remains available, the market may be telling you something.
A thoughtful adjustment can reposition a home.
That is different from automatically reducing the price because a certain number of days have passed.
Look at:
Showing activity
Buyer feedback
Disclosure interest
New competition
Recent pending sales
Comparable closings
Then make the decision based on evidence.
One More Number To Watch Carefully: Price Per Square Foot
Price per square foot is useful.
It just does not make my top five.
Why?
Because buyers do not purchase square footage in isolation.
A 1,500-square-foot remodeled Willow Glen home on a beautiful lot may sell at a much higher price per square foot than a 2,500-square-foot property needing substantial work.
Santa Clara County's August median was $1,066 per square foot for single-family homes and $683 for condos and townhomes.
Those countywide figures are useful context.
They are not a formula for pricing an individual house.
Use price per square foot when the properties are truly comparable.
Why Hyper-Local Numbers Matter More Than Silicon Valley Headlines
“Silicon Valley housing market” is useful shorthand.
It is not one market.
Consider just the distinction between detached and attached homes in Santa Clara County in August:
Single-family homes
$1.85M median sale price
12 median days on market
103% sale-to-list ratio
1.5 months of inventory
Condos and townhomes
$846,944 median sale price
26 median days on market
100% sale-to-list ratio
3.1 months of inventory
Same county. Very different conditions.
Then narrow further to:
Willow Glen
Cambrian
Campbell
Los Gatos
Almaden
Palo Alto
Sunnyvale
Santa Clara
And the numbers change again.
Narrow to one ZIP code or neighborhood.
They change again.
Narrow to renovated 3-bedroom homes on quiet streets within a particular price range.
Now you are getting much closer to the market that actually matters.
The 5 Numbers I Would Ask for Before Buying or Selling
If someone hands you a market report with 25 statistics, start here:
1. Median Sale Price
What have buyers actually been paying, and how has that changed?
2. Months of Inventory
How much choice do buyers currently have?
3. Median Days on Market
How quickly are comparable homes moving?
4. Sale-to-List Ratio
How are final sale prices comparing with sellers' asking prices?
5. Price Reductions
How often is the market forcing sellers to reposition?
Then ask for those numbers at the smallest useful geographic and property-type level.
That is where market statistics become actionable.
The Bottom Line
No single number tells you whether it is a good time to buy or sell a home in Silicon Valley.
A median price tells you one thing.
Inventory tells you another.
Days on market tells you something else.
Put them together, and you begin to see the real market.
For sellers, those numbers help shape pricing, preparation, and expectations.
For buyers, they help you understand competition, timing, and where negotiation may exist.
And in a market as varied as Silicon Valley, the most useful statistics are rarely countywide averages.
They are the numbers describing the homes you are actually competing with.
If you are buying or selling in Willow Glen or elsewhere in Silicon Valley and want to understand what the numbers mean for your particular property or home search, reach out direct.
Market statistics change over time and vary by geography, property type, price range, and individual property. Broad market data should be used as context rather than a valuation or prediction for a specific home.
