Key Takeaways
•The short answer: Somerville's condo median sale price fell 4% this year, per MLS Pinergy. That does not mean a typical home lost value. It mostly reflects which homes happened to sell.
•The proof: MLS Pinergy figures through August 31 show average sale prices for condos, single-families and multi-families all at or near record highs. Falling markets don't set records.
•The same-home test: The Zillow Home Value Index, which tracks the same homes over time, puts Somerville at $920,007, up 0.1% year over year. That is flat, not falling.
•The bottom line: Price your home from its closest comparable sales and its price per square foot, not from a citywide headline.
Medians Are Down. Is Your Condo Really Worth Less?
Picture a Somerville condo owner reading a fall market update. One line jumps out: "condo median down 4%." The natural fear is that the home just lost value.
In most cases, the answer is probably not.
MLS Pinergy figures through August 31 put the condo median at $865,000, down 4% from year-end 2025. The average condo sale, though, reached $945,989 — up 0.05% and the second-highest average on record.
How can a median fall while the average sits near a record? The median reflects which homes sold. It doesn't show what happened to the value of your specific home.
The median moved because the mix of homes that sold changed. Individual homes did not broadly lose value.
The real question isn't "Did prices fall?" It's which homes sold, where, how large, and in what condition.
How Can a Median Fall Without Homes Losing Value?
The median is simply the middle sale. Line up every closed transaction from lowest to highest, and the one sitting in the center is your median.
In a city like Somerville, that math can mislead. If more small condos close in one stretch, or fewer large renovated homes sell, the median drops — not because values fell, but because the "middle" home was a different home entirely.
Economists call this a mix shift. In plain English: the basket changed.
Price per square foot cuts through that noise. It shows what buyers actually paid for space. If your home is larger, updated, or better located, with parking or outdoor space to boot, a citywide median may seriously understate what buyers would pay for it.
What Do the Average Prices Tell Us?
Somerville's major property types tell the same story this year, per MLS Pinergy:
•Single-family: average $1,493,894, the highest on record; median $1,350,000, down 2%.
•Multi-family: average $1,505,261, up 2% and the highest on record.
•Condo: average $945,989, near a record; median $865,000, down 4%.
A broad selloff doesn't look like this. If the whole market were falling, averages would weaken too. Instead, they're sitting at or near records — buyers are still paying strong prices for the right homes.
For you, that means one thing: don't price your home off a single citywide median.
Isn't a Falling Median an Early Warning Sign?
It can be, so don't wave it off entirely.
Somerville values aren't climbing fast right now. Zillow's 0.1% year-over-year figure means growth has basically stalled. But stalled isn't falling. The Zillow index tracks the same homes over time, so it doesn't depend on which homes happened to sell in a given month.
Buyers do have more choice than a year ago. Realtor.com shows active listings up 30.81% from last year, with the median listing price down 4.08%.

That extra supply gives buyers breathing room, and it can pressure asking prices when sellers start too high. But it hasn't dragged sold values down across the board.
What Are the Fair Objections to This Reading?
You might be thinking: isn't "mix shift" just real estate spin?
Fair concern. The median resists extreme outliers, but it doesn't adjust for size, condition, bedrooms, parking, outdoor space or neighborhood. That's exactly why the same-home Zillow index matters — it shows Somerville basically flat, not broadly lower. Citywide figures also don't separate sales by size or neighborhood, so some softening among lower-priced homes can't be ruled out. Your own comps still matter more than any headline.
A second objection: could record averages just be a few expensive homes skewing things?
Partly, sure. High-end sales always pull averages upward. But look at how close the averages sit to the medians here. The single-family median of $1,350,000 isn't far below its record average. The condo median is close to its average too. If a handful of trophy sales were driving these records, the gap between average and median would be far wider — and the condo average only rose 0.05%, hardly a spike.
Averages can still skew high, so lean on comparable sales rather than any citywide figure.
Why Do Somerville's Numbers Swing So Much?
Somerville is dense, varied and condo-heavy. A unit in a converted triple-decker can sell near a renovated single-family. A smaller condo near Magoun Square isn't the same product as a larger one near Davis, Porter or Union.
Property type matters too. In a recent MLS PIN snapshot, single-family homes posted the highest median sold price, $1,355,000, and sold faster than condos — a median of 21 days on market versus 28.

Condos in that same snapshot sold for a median of $752,500, below their year-to-date figure. Don't read that as a sudden drop — a short window captures only a small, noisy sample. The year-to-date number is the steadier guide to where condo values actually stand.
Shift a few sales between property types, and the citywide number moves even while demand stays steady.
Local rules matter too. Per the City of Somerville, new regulations took effect October 1, 2025. Owners converting a vacant, formerly tenanted unit must now give the Condominium Review Board two years' notice, up from one. Relocation payments also rose to $14K, or $18K for seniors, disabled tenants and low-to-moderate-income tenants. Slower conversions may affect which condos come to market over time.
How Should You Read Your Home's Value This Fall?
Skip the citywide headline. Start with your closest comparable sales — homes of the same property type, similar size and condition, in a nearby location. Find the three to five best matches if you can.
Then compare your home's price per square foot against those comps. Where you land depends on condition, layout and location.
And remember: your assessed value, the figure the city uses to calculate property tax, isn't your market value. It won't tell you what a buyer will actually pay today.
What Should Sellers Do Now?
Don't cut your price just because you saw a negative headline. Averages near records show that well-prepared homes still sell.
But pricing needs to be sharper. Well-priced homes go pending in about 18 days, per Zillow. Listings that miss on price sit a median 53 days on realtor.com, up 19.56%. Buyers have more choices now and will compare your home against the best recent alternatives — condition, presentation, layout, outdoor space, parking and location all factor in.
The right strategy isn't "price high and wait." It's price from the best comps, present the home well, and adjust quickly when the market gives feedback.
What Should Buyers Do Now?
A lower median doesn't mean bargains are everywhere. It does mean you may have more leverage on homes that are overpriced, dated, or sitting longer than similar listings.
Focus on the monthly payment, not just the sale price. Weigh what matters most to you — walkability, transit, school access, outdoor space, parking or rental flexibility. In Somerville, two homes at the same price can feel completely different to live in.
What Is the Bottom Line for Somerville Home Prices This Year?
Yes, the median fell. At the same time, averages sit at or near records. Both are true because the median tracks which homes sold, not what any single home is worth. The same-home Zillow index, flat at 0.1%, confirms values are holding rather than falling.
This isn't a simple "prices are falling" story. The market has grown more selective. The mix of sales is shifting, buyers have more options, and the best-positioned homes still command strong prices.
To find your real number, skip the citywide median. Use your closest comps, your home's condition, its square footage and its exact location.
If you want to see the specific numbers for your Somerville condo, single-family or multi-family, ask for a property-level pricing review before your next move.
