The average home price in West Roxbury was up 26.5 percent year over year as of August 2026, according to Redfin. Over roughly the same window, the median sale price was down 4.9 percent. Both numbers come from the same neighborhood, the same data provider, and overlapping time periods. Neither one is wrong.

That gap is not a data error and it is not evidence of a market losing its footing. It is what happens when a small number of very expensive new-construction sales land on top of a housing stock that is still, for the most part, the same colonials and bungalows that have been selling in West Roxbury for decades. If you are pricing a purchase against the neighborhood's "average" or "median," it matters which one you are looking at, and it matters more this year than most.

What a Mean Actually Measures

An average adds up every sale price and divides by the number of sales. A single home that sells for well above the pack pulls that number up, even if nothing else in the neighborhood changed. A median just finds the middle sale and ignores how far above or below it the outliers sit. Most years, in most neighborhoods, these two numbers move together closely enough that nobody has to think about the difference.

This is not most years for West Roxbury. A new subdivision of single-family homes started closing sales in 2026, and it takes only a few sales at more than double the typical price to bend a mean without moving a median at all.

A $1.65 million closing sits next to a run of $780,000 colonials in the same reporting period. The average climbs. The middle sale price barely notices.

The Subdivision Behind the Swing

The clearest evidence of this is a property the Boston Globe featured as its Home of the Week in March 2026: 16 Starling St., a 2,700-square-foot single-family home listed at $1.65 million inside a brand-new development called The Preserve at Cardinal Hill. The Globe called an entirely new subdivision of single-family homes inside Boston city limits "a Boston rarity," and it is. Most new residential construction in Boston neighborhoods arrives as condo conversions or infill lots, not a platted subdivision with its own street, in this case Starling Street, built out against roughly 90 acres of conservation land. The home came with a farmer's porch, a formal dining room, and a walk-up attic, features that read more like a suburban new-build than a typical West Roxbury resale.

The Preserve at Cardinal Hill is not the only new supply pulling West Roxbury's price data upward. Laurel Residences, a boutique new condo building, has been reported as roughly 75 percent sold or under contract, and 1789 Centre, a newer-construction townhome-style condo development in the heart of the neighborhood, has been offering garage parking and updated finishes at a premium over older condo stock nearby. None of these represent a large share of total transactions. That is exactly the point. It does not take many sales like these to move an average once you understand how averages work.

What the Older Housing Stock Still Looks Like

Set the new construction aside and West Roxbury's underlying housing stock has not changed much. Local market data compiled earlier this year shows most sales clustering in the $700,000 to $900,000 band, with per-square-foot pricing running roughly $500 to $545 depending on the home and its exact location. The neighborhood's housing mix leans more toward detached single-family homes than most Boston neighborhoods, with a meaningful number of two-families and small multis mixed in, and much of that stock was built before 1940 through the mid-20th century: classic colonials and bungalows on established lots, not the triple-deckers that define the housing stock in several neighboring Boston neighborhoods. West Roxbury also includes close to 1,200 acres of open space, which is part of why detached homes with real yards remain the norm here rather than the exception.

Here is what that split looks like side by side:

A buyer touring the older stock is shopping in one price world. A buyer touring the new subdivision or the new condo buildings is shopping in another. The neighborhood-wide average blends both worlds into one number that describes neither.

Why the Median Slipped Even as Competition Stayed Tight

The median dropping almost 5 percent might read as softening demand, but the rest of the data does not support that story. Homes in West Roxbury received 3 offers on average over the same three-month window and sold in around 21 days, giving the neighborhood a Redfin Compete Score of 82 out of 100, still solidly in competitive territory. Per-square-foot pricing was actually up 0.9 percent over the same year-over-year window, which is a meaningful distinction: if buyers were paying less per square foot, that would point to softening values. Instead, per-square-foot pricing held essentially flat to slightly up, while the median dollar figure fell. That combination points to a mix shift rather than a value decline. Fewer of the year's transactions were large single-family homes, more were smaller resales, and 109 homes sold in July 2026 compared with 121 the year before, a modest pullback in overall volume rather than a demand collapse.

Zillow's home value index, which is model-based rather than built directly from a rolling set of closed sales, showed West Roxbury essentially flat over the past year. That is another way of seeing the same effect: a methodology built to smooth out unusual individual sales barely moved, while a straight average of actual closing prices jumped by more than a quarter. Three legitimate ways of measuring the same neighborhood, three different headlines, and only one of them is telling you what a typical West Roxbury home actually sold for this year.

What This Means If You're Comparing West Roxbury to Other Neighborhoods

Buyers comparing West Roxbury against Jamaica Plain, Roslindale, or Dorchester are often comparing single median or average figures across neighborhoods with very different housing compositions. West Roxbury's stock is genuinely different in kind, not just in price. Homes within walking distance of the West Roxbury station on the Needham Line offer a one-seat commuter rail ride to Back Bay and South Station, a different commute profile than neighborhoods served primarily by subway or bus. Larger lots and off-street parking are common, which usually means fewer shops within a short walk, while condos closer to Washington Street trade some of that private outdoor space for better walkable access to daily errands.

None of that shows up in a single median price. Before comparing a West Roxbury listing to "the neighborhood median" you see on a portal, it is worth asking your agent whether that median reflects a typical resale or whether it is being shaped by this year's new-construction closings. Right now in West Roxbury, that answer changes which number you should actually be comparing your offer against.

FAQ

Is West Roxbury currently a buyer's market or a seller's market? The competition data still points to sellers. A Redfin Compete Score of 82 out of 100, homes averaging 3 offers, and a typical 21-day time on market over the three months ending July 2026 all describe a tight market, even with the median price dip.

Are there new construction options in West Roxbury beyond The Preserve at Cardinal Hill? Yes. Laurel Residences and 1789 Centre are both newer-construction condo developments that have added to the neighborhood's small but growing supply of new-build inventory, alongside the single-family homes coming out of The Preserve at Cardinal Hill subdivision.

Does West Roxbury have the same triple-decker housing stock as nearby Boston neighborhoods? Not to the same degree. West Roxbury's housing mix leans more heavily toward detached single-family homes and two-families, with much of the stock dating to before 1940 through the mid-20th century, rather than the triple-decker-dominant stock found in several neighboring Boston neighborhoods.
