# Low Rate, High Bill: Why Lexington's Cheaper Tax Rate Buys No Advantage
Key Takeaways
•The short answer: Lexington's FY2026 residential rate of $12.31 per $1,000 is lower than Westwood's $12.80 per $1,000 — and it buys no advantage, because bills track assessments, not rates.
•The reason: The rate is only the multiplier. Assessed value — what the town says your home is worth — is the number being multiplied.
•The bottom line: Compare bills, not rates. Pull the parcel's assessed value from the town assessor, multiply, and budget for a bump after you close.
Why Does the Cheaper Tax Rate Not Make Lexington Cheaper?
Say you're touring Lexington, Belmont, and Westwood this fall. Lexington's rate page looks cheaper. That tells you almost nothing.
The math itself is simple: take the assessed value, divide by 1,000, multiply by the tax rate.
The Steinmetz Real Estate team's FY2026 rate guide puts Lexington at $12.31 per $1,000. Steve Novak Real Estate's Westwood guide lists $12.80 per $1,000.
On every $100,000 of assessed value, Westwood charges $1,280 and Lexington charges $1,231. Per dollar of house, Westwood is actually the more expensive town. So any gap between the bills has nothing to do with the rate — it comes down to what each town says the house is worth.
Statewide, 230 Massachusetts towns cut their rates this year, against 109 increases and 4 unchanged. A falling rate still tells you nothing about your bill, since your assessment can climb faster than the rate falls.

How Does Lexington Turn a Lower Rate Into a Higher Bill?
Lexington's average single-family tax bill hits $20,394 in 2026, according to MassLive's town-by-town tally — roughly $1,700 a month, before mortgage, insurance, heat, or repairs. Belmont averages $19,579, within about 4% of Lexington. Two towns, two different rate pages, nearly the same bill.
Buyers accept this for the schools, the long-term demand, the resale depth. But a high assessed value makes every future re-valuation more expensive, so don't budget off the seller's current bill.
Why Does Westwood Read Cheaper Only at the Entry Level?
On typical homes, the two towns land close together: Lexington's $20,394 average against the Novak guide's $21.3K typical Westwood bill on a roughly $1.66M median. By those figures, the typical Westwood owner actually pays more than the typical Lexington owner.
Westwood only reads cheaper if you're buying at the entry level. The same $900,000 assessment costs $11,520 a year in Westwood versus $11,079 in Lexington — Westwood remains the costlier town per dollar of value. What moves the bill isn't the rate. It's what the town says the house is worth.
Statewide, the average single-family bill reached $8,111 in 2026, up from $7,059 in 2023, per MassLive. Between FY2016 and FY2025, statewide assessed value rose from $1.030 trillion to $1.911 trillion — which explains why bills climb even when rates hold steady.

What Are the Strongest Arguments Against This?
"That's house price, not tax policy. On rate alone, Lexington really is cheaper."
Correct — and that's exactly the point. When rates sit this close, rate shopping barely moves your monthly cost. Valuation does.
"Those averages come from a MassLive town-by-town tally that circulates widely on agent blogs and social feeds — useful journalism, not parcel records."
Fair, and worth conceding. These aren't parcel records, so don't price an offer off them. They're good for building a shortlist, nothing more. The only number that governs your bill is the assessed value on that specific parcel's assessor record.
"Buyers already price taxes into what they offer, and high assessments signal a stronger, more liquid market — the bill is just the cost of owning an appreciating asset."
Partly true. Taxes do get priced in at purchase. But that adjustment happens once, while the bill arrives every quarter. Appreciation is future money; a $20,394 bill against an $11,520 bill on an entry-level house changes what you can actually carry each month.
What Should Massachusetts Buyers Do This Fall?
•Compare bills, not rates. Pull the parcel's assessed value, multiply by the current rate, then budget for the town to re-value the property after you close.
•Model the full monthly cost: mortgage, taxes, insurance, heat, repairs, commute.
•Ask about an abatement — a formal request asking the town to lower its valuation of your home. Confirm eligibility and deadlines with your agent or assessor; the Steinmetz team reports recoveries of $2,000–$8,000 a year.
•Ask which exemptions exist for seniors, veterans, and disabled owners, and confirm current rules with your agent.
•Verify before you bid. Figures circulating this September carry different fiscal-year labels. Call the assessor for the current one.
The real question isn't which town has the lower rate. It's which town's valuations you want to own for the next decade.
Get the parcel's assessed value and the current rate before you write an offer — that's the only bill that will actually show up.
