Open three tabs and search the same address in Westwood. One site tells you the typical home here is worth just over $1.09 million. Another says the median sale last reported came in at $1.3 million. A third lists the current median asking price near $1.87 million. Nobody moved. Nobody lied. You are looking at three different measurements of the same small town, and the gap between them is the actual story worth understanding before you use any of these numbers to compare Westwood against Needham, Wellesley, or Weston.
The confusing part isn't that the numbers disagree. It's that Westwood's own most recent data proves prices can rise on paper while the cost of actual square footage falls in the same month.
Three Sites, Three Different Westwoods
Each portal is answering a different question, and none of them is wrong.
| Source | What it measures | Latest figure | Period |
|---|---|---|---|
| Zillow Home Value Index | A smoothed estimate of the typical home's value across the entire housing stock, adjusted monthly for property mix | $1,096,482, up 4.4 percent year over year | Currently published, recalculated monthly |
| Redfin median sale price | The middle price among homes that actually closed | $1.3 million, up 5.7 percent year over year | November 2025, the most recent month Redfin had fully reported |
| Movoto median list price | What sellers are currently asking, not what's closing | $1.87 million | July 2026 |
Zillow's index is built specifically to smooth out the effect of which homes happen to sell in a given stretch. Redfin and Movoto report on whatever activity actually occurred that month, which in a town the size of Westwood can mean a handful of transactions driving the whole figure. That difference in method, not a disagreement about the market, is why the three numbers never quite line up.
The Number Redfin Publishes Right Next To The One That Contradicts It
Here is the detail that matters more than any single median. In the same November 2025 report where Redfin listed the median sale price up 5.7 percent, it also listed the median price per square foot down 15.1 percent over that same year. Only seven homes sold in Westwood that month, up from six the year before.
Read those two numbers together and the story changes. A rising median dollar figure paired with a falling price-per-square-foot figure cannot mean the town got more expensive to build or buy into. It means the homes that happened to close were larger. Square footage went up faster than price did, which pulls the median sale price higher even as the cost of any given square foot actually eased.
That is not appreciation. That is a change in which homes sold.
The Same Signature Shows Up Again in July 2026
If November 2025 were an isolated blip, it would be easy to dismiss. It isn't. Movoto's own listing data from this summer shows the identical pattern. In June 2026, the median list price in Westwood was $1.83 million with a median value of $521 per square foot. By July 2026, the median list price had climbed to $1.87 million while price per square foot dropped to $508. Days on market lengthened too, from 43 days in June to 53 in July.
Bigger asking prices, smaller per-square-foot values, slower sales. That combination points to the same mechanism at work eight months later: larger homes entering the pool of what's for sale, not a townwide markup on every property already sitting on the market.
Why the Mix Keeps Shifting: Islington and the Pine Hill Corridor
Westwood is not one housing market wearing one price tag. It's two distinct pockets that happen to share a town line.
Islington is the older half. Homes here cluster around a stock built mostly between the 1940s and 1960s, walkable to the Islington stop on the Franklin/Foxborough commuter rail line, and within a short walk of Muffin House and Neroli Ristorante, the kind of local businesses that give the village its own identity separate from the rest of town.
The other half sits closer to the Pine Hill School District and the University Station corridor, served by the Route 128 stop on the Providence/Stoughton Line and anchored by the University Station retail complex. This is where the newer, larger construction lives, the five-plus-bedroom colonials on acre lots that reporting on the broader Westwood market has described running from around a million dollars for a dated two- or three-bedroom home up toward figures approaching ten million for modern builds with pools and tennis courts.
The Pine Hill School District carries a specific, dated reason to matter right now. The Pine Hill Elementary School building project was completed in 2024, a full rebuild that has kept that attendance zone squarely on the radar of family buyers looking for new-construction schools paired with new-construction homes. When a disproportionate share of a thin monthly sales sample comes from that side of town, the townwide median moves accordingly, even though nothing changed for a seller sitting on a smaller home in Islington.
That is the mechanism behind both the Redfin and the Movoto numbers. Westwood's median isn't measuring appreciation across a uniform town. It's measuring which of two very different housing stocks happened to trade hands that month.
What to Ask For Instead of the Townwide Median
If you're using Westwood's numbers to size up a move here, or to compare it against Needham, Wellesley, or Weston, the townwide median is the least useful number available to you. Ask for the comparison that actually matches your search instead.
- Request price per square foot trends filtered to the specific school attendance zone or village you're targeting, not the town as a whole.
- Ask how many homes actually closed in the comparison period. A median built on seven sales moves very differently than one built on seventy.
- Separate list price from sold price. Movoto's list-price figures show what sellers are asking this summer. They don't show what buyers are actually paying.
- If a home's size and lot are unusual for its neighborhood, treat any townwide comparison as a starting point for conversation, not a number to negotiate from.
A Few Direct Questions
Does this mean Westwood home values are actually falling? No. It means the townwide median is a poor tool for tracking value change in a market this small and this split between two distinct housing types. Zillow's mix-adjusted index, which smooths for exactly this effect, still shows a steady 4.4 percent annual gain. The volatility shows up in the raw monthly medians, not in the underlying trend.
How should I compare Westwood to a town like Needham or Wellesley using this data? Match the metric type before you match the town. Compare Zillow's index to Zillow's index, or Redfin's median-sold to another town's median-sold from the same month. Mixing a list price from one town with a sold price from another will produce a comparison that looks meaningful and isn't.
Numbers like these are exactly why a townwide median deserves a second look before it drives a decision.
