Two homes list the same weekend in Saratoga. Similar square footage, similar age, similar block feel. One closes near $4.1 million. The other trades closer to $3.5 million. The portals will average them and hand you a citywide number that describes neither.
The number they publish is real. It is also a mix-shift artifact. In a 14-transaction month, the composition of what sold explains more of the movement than any change in underlying demand. If you are comparing Saratoga to Cupertino or Los Gatos from the median row on a search page, you are looking at the least useful number in the file.
The friction that surfaces at the offer table
The most common surprise for buyers writing their first Saratoga offer is not price. It is the discovery that an address in the 95070 ZIP does not automatically feed into the Saratoga Union School District. The city sits across four different TK–8 elementary districts, and the assignment is made by parcel, not by street name or subdivision.
SUSD is explicit about this: residences located in the City of Saratoga feed into four different transitional kindergarten through eighth grade elementary school districts: Campbell, Cupertino, Moreland and Saratoga Union School District. The district also notes that there is no SUSD boundary map published for distribution and district assignments are based on the data via the Santa Clara County Assessor's office.
That last sentence is the transaction-relevant one. There is no map you can pull off a city page and hand to a buyer. Assignment runs off the APN, which means the boundary can cut through what looks on satellite view like a single continuous neighborhood. Two homes on the same street can pull different feeds. Contract contingencies, appraisal comps, and buyer pool all shift accordingly.
Why one ZIP produces four feeds
Saratoga Union School District encompasses approximately 8 square miles of territory, including about 2/3 of the city of Saratoga and small portions of the cities of Monte Sereno and Los Gatos, as well as a portion of unincorporated Santa Clara County. That leaves roughly a third of the city assigned elsewhere. The four TK–8 feeds sit above a single grade 9–12 feed for SUSD residents, the Los Gatos–Saratoga Joint Union High School District, which shapes buyer overlap with Los Gatos and Monte Sereno.
Inside SUSD, the elementary layer works differently than most buyers expect. SUSD is an open enrollment district which means no property addresses have been assigned to a specific school, and parents may request the TK-5 school within the district they wish their student to attend provided the student resides within the boundaries of our district and space permits. Choice among Argonaut, Foothill, and Saratoga Elementary is granted by availability, not by street. All SUSD sixth through eighth graders then attend Redwood Middle School.
For a buyer, the practical order of operations is:
- Confirm the district assignment through SUSD's District Finder, and cross-check with the Santa Clara County Assessor at (408) 299-5500 if the address does not resolve.
- Ask the listing agent for the APN and verify feed independently. Do not rely on the marketing sheet.
- If SUSD-assigned, understand that elementary placement is space-based, not address-based.
- Confirm the high school feed. LGSUHSD coverage is not automatic across every Saratoga parcel.
That four-step check answers the question that actually moves price, and it answers it before an offer date.
Reading the current numbers without getting fooled
Here is where two respected data sources appear to disagree, and where knowing the mechanism matters.
| Source | Window | Reading | What it measures |
|---|---|---|---|
| Redfin | April 2026 | Median $3.6M, down 14.9% YoY, 9 days on market | Sold prices, MLS-fed |
| Zillow ZHVI | May 2026 | $3,468,553, down 6.2% YoY | Modeled value across all homes |
| Altos Research | June 3, 2026 | Median list $4,849,000, Market Action Index 49 (up from 47), inventory ~37 | Active list prices |
| Brasil Group snapshot | May 15, 2026 | 39 active listings, 33 avg DOM, $1,517/sf, $4.5M median list | Active list prices, MLSListings feed |
Redfin's April figure captures the median home price in Saratoga at $3.6M as of April 2026, representing a 14.9% decline from April 2025. In February 2026, the same source showed the opposite direction: Saratoga home prices were up 4.8% compared to last year, selling for a median price of $3.5M, and on average, homes in Saratoga sell after 13 days on the market compared to 9 days last year.
A market cannot swing from up 4.8% to down 14.9% in two months on real demand. It can look like that when there were 14 homes sold in February this year. At that transaction count, one extra estate closing at $8 million or one fewer closing at $2.5 million rewrites the median.
Altos, which reads list prices from active inventory, tells a different story for the same city in the same season. This week the median list price for Saratoga is $4,849,000 with the market action index hovering around 49, an increase over last month's market action index of 47, and inventory has held steady at or around 37. Small inventory, thin transaction counts, and a wide price band across sub-areas do not produce a clean citywide trendline. They produce noise that looks like a trend.
The citywide median in a low-volume, high-dispersion market is not a signal about direction. It is a signal about which sub-areas cleared escrow that month.
What your money buys once you cross a line
The sub-area dispersion is where the boundary map shows up in dollars. Pulling from Redfin sub-market data cited in an April 2026 analysis of Saratoga:
- Central Saratoga (the core of 95070) carried a median around $4.0M, down 4.2% year over year.
- Northwestern Saratoga sat near $4.1M, down only 0.84%.
- Southeastern Saratoga sat near $3.5M, down 26.1%.
- Saratoga Oaks was the only sub-area with positive momentum at +5.8%.
Those spreads are wider than most buyers assume a single city can produce. A buyer working from a $3.6M citywide anchor will underbid one section and overbid another. The dispersion also explains why price per square foot is a more stable comparison tool here than the median. As of May 15, 2026, 39 homes were listed with an average 33 days on market at $1,517.38 per square foot and a $4,500,000 median list price. Price per square foot smooths the composition problem the median cannot.
Interpreting that spread through the boundary lens: the sub-areas holding value best correlate closely with the SUSD footprint and its overlap with LGSUHSD. The sub-areas showing steeper declines include more parcels assigned to Campbell, Moreland, and portions of Cupertino Union. This is not a statement about school quality. It is a statement about buyer pools. Different districts attract different move-up buyers with different budget ceilings, and those ceilings set clearing prices at the margin.
Diligence questions before you write the offer
- What is the parcel's TK–8 district assignment, confirmed against the County Assessor record, not the listing sheet?
- What is the high school feed, and does it match the assumption baked into the comparable sales the listing agent presented?
- Which sub-area do the appraiser's likely comps come from, and does the appraiser typically split at the boundary line or blend across it?
- If the district is SUSD, has the seller inquired about current-grade space availability at Argonaut, Foothill, or Saratoga Elementary for the buyer's timeline?
- On price per square foot, does the offer sit within the sub-area's recent range, or the citywide range? The two are not the same number.
A short FAQ
Is the citywide median useful at all? As a directional check across years, and as a comparison against Cupertino or Los Gatos at the metro level, it holds. As a pricing anchor for a specific home in a specific sub-area, it is too coarse to be actionable.
Why does Altos show a rising market while Redfin shows a decline? They measure different things on different timelines. This answers "How's the Market?" by comparing rate of sales versus inventory. Altos reads active list prices and absorption. Redfin reads closed sales. In a market with 14 to 40 monthly transactions and wide sub-area dispersion, the two can point opposite directions for months at a time without contradicting each other.
How do I verify a school district assignment before offer date? Run the address through the SUSD District Finder page. If the address does not resolve, the SUSD guidance is direct: check the spelling or street number or search using the property APN number, and contact the Santa Clara Tax Assessor's Office at (408) 299-5500.
Does the boundary map explain everything about price? No. Lot size, condition, view, and street orientation all still matter. The boundary explains a piece the portals leave out. On close comparisons between similar homes at similar price points, it is often the piece that resolves the gap.
Working the boundary map into a strategy
The reader who wins in this market is the one who stops treating 95070 as a single field and starts treating it as a mosaic. That reframes the search, the comp set, the offer strategy, and the diligence checklist. It is also the piece a portal cannot do for you, because the underlying data is a parcel-by-parcel lookup that lives with the County Assessor.
