Montville's mill rate jumped 8.9% this year, and unlike most of the increases you'll read about in Connecticut, this one's for real. There's no revaluation behind it. Montville doesn't revalue until the October 1, 2026 Grand List, this fall. And the market moved right along with it: 209 homes sold at a median of $356,000 in 21 days at 103.0% of asking, with volume up 20% in a year.
I sell all over New London County, so let me tell you what I'd want to know if I were buying here.

The number I'd look at is 209 closed sales, up from 174 — a 20% jump in volume, and only Norwich and Groton close more houses in this county. Price only moved 3.5% & the percent of list sat at exactly 103.0% both years. That combination tells me something specific. Montville is absorbing demand, not repricing it. More houses traded, at about the same premium, in about the same time. Buyers who can find inventory are getting deals done here, and the market isn't running away from them.
This is the thing that catches people, and it works backwards from what almost every buyer assumes.
Mohegan Sun sits in Montville, on the Mohegan Tribe's reservation. So buyers figure a resort that size has to be carrying the town's tax base. It isn't. Reservation land is held in federal trust and is not on Montville's property tax rolls at all. The town can't assess it and can't bill it.
What Montville gets instead is a state grant out of the Mashantucket Pequot and Mohegan Fund:
Town | FY2027 grant | Per resident |
Norwich | $2,360,229 | ~$59 |
Montville (hosts Mohegan Sun) | $1,446,162 | ~$79 |
Ledyard (hosts Foxwoods) | $1,391,000 | ~$90 |
$1,165,290 | ~$243 | |
$880,690 | ~$171 | |
$55,478 | ~$4.87 |
Montville hosts the larger of Connecticut's two casinos and gets less per resident than Preston, North Stonington or Ledyard. The formula pays on proximity and historical impact, not on who does the hosting. So if you're buying here on the theory that casino money keeps your taxes low, drop the theory. The mill rate below is the actual answer.
Montville's rate for FY2026-27 is 31.43 mills, up roughly 8.9% over last year.
All over Eastern Connecticut right now I'm explaining the opposite situation — towns whose mill rates dropped hard because they revalued, where the drop is just arithmetic and nobody's actually saving money. Montville's the clean case going the other way. The town's next revaluation is the October 1, 2026 Grand List, happening this fall, hitting bills in July 2027. So the FY2026-27 increase has nothing to do with assessments. It's a budget increase landing on a grand list that hasn't been reset yet.
What that means for you, practically:
On a $356,000 house — the town median — assessed at Connecticut's standard 70% of market value, you're at about $249,200. At 31.43 mills, that's roughly $7,832 a year. Run that against your actual mortgage math before you write an offer, because it's real money & it just moved.
And then it changes again. The October 2026 revaluation resets every assessment in town to current market value. Montville's median has climbed from $344,000 to $356,000 and the town last revalued five years ago, so assessments are very likely going up a lot — and the mill rate will come down to compensate. What your bill does after that reval depends entirely on whether your assessment moves more or less than the town average. Houses that appreciated faster than the town pay more. Houses that lagged pay less. The rate number by itself won't tell you a thing.
If you're buying in Montville in late 2026, you're buying a property whose assessment is about to be redetermined. Ask the Assessor about it, and ask me too. I've walked plenty of clients through exactly this.
You'll see Montville houses listed with an Uncasville address, and you'll see people searching "Uncasville real estate" like it's a separate municipality. It isn't.
Uncasville is a village within the Town of Montville — a postal designation and a place name. No government of its own, no separate tax rate, no separate school district. Montville's own Town Hall carries an Uncasville mailing address, which tells you how tangled this gets.
Montville's villages are Uncasville, Oakdale, Chesterfield and Mohegan. All four are Montville. Same mill rate, same schools, same assessor, same building department. What changes is character and location — Uncasville runs along the Thames toward the casino and Norwich, while Oakdale and Chesterfield sit inland and more rural, out toward Salem and the lakes.
So here's the practical version: don't narrow a home search to one village name and figure you've seen the town. A lot of Montville inventory gets listed under village names, and a buyer searching only "Uncasville" is missing most of what's out there.
Montville runs its own PK–12 district, Montville High School included. That puts it in the minority among the smaller towns in this part of the county — Bozrah, Franklin, Lisbon, Preston, Sprague and Voluntown all send their high schoolers out of town, usually to Norwich Free Academy.
If having one district start to finish matters to your family — kindergarten through graduation in one system, no tuition arrangement, no choice application — that's a real point in Montville's favor. Buyers comparing it to the neighboring towns miss it all the time.
Gardner Lake covers 529 acres and straddles three towns — Montville, Salem and Bozrah. One lake, three mill rates, three assessors, three school districts.
That matters more than it sounds like it should. Two houses on the same water, a quarter mile apart, can sit in different towns with wildly different tax bills and different schools. When you're looking at a Gardner Lake listing, confirm the town of record first. It drives just about everything about what owning there is like.
There's a public boat launch and beach on the southern shore at Gardner Lake State Park, so this is publicly accessible water, not private-association lakefront. That cuts both ways. No association dues and nobody gatekeeping the water, but also summer traffic you don't control.
State surveys have found a healthy native plant community with two invasive species present at low abundance — fanwort and variable-leaf watermilfoil — roughly stable between 2006 and 2015. If you're buying to boat, that's something to check on, and the lake association is who I'd call for a current read.
Montville is well outside the 20-mile crumbling-concrete foundation radius centered on the former J.J. Mottes Concrete Company in Stafford Springs. That issue shapes how I write inspections in Tolland and Windham County. It's not a Montville problem.
Septic and well permits go through the Uncas Health District, which covers Montville along with Bozrah, Franklin, Griswold, Lebanon, Lisbon, Norwich, Preston, Salem, Sprague and Voluntown. If you're buying a house on well and septic — and much of Montville outside the Thames corridor is — Uncas is who inspects it and who holds the records on the existing system. Pull those records during diligence, not after you close.
One scheduling note that'll save you a trip: Montville's Assessor's office keeps Friday hours, which isn't a given around here. Several neighboring towns run four-day weeks and simply can't help you on a Friday. Confirm current hours before you drive over, but Montville's generally the easier stop late in the week.
You're selling into the county's third-busiest market — 209 sales, up 20% — at a steady 103% of asking. That's a healthy, liquid market. Twenty-one days is fast.
Two things I'd get ahead of.
The tax question is coming, so answer it first. A buyer who stumbles onto an 8.9% mill rate increase in their own research, after they've already fallen for the house, treats it like something you hid from them. A seller who lays it out upfront — the rate went up, here's what the bill actually runs, and the October revaluation resets assessments town-wide — just comes off as credible. The number is the same either way. All that changes is whether they trust you.
If your listing carries an Uncasville, Oakdale or Chesterfield address, market it as Montville too. Buyers typing the town name should land on your house. It's a small thing, and it quietly costs sellers showings.
If you want a real number for your home, call me. I'll walk the property, pull the actual comps for your village and your price band, and tell you honestly what I think it brings.
And if part of what you're weighing is whether you need me at all — some people genuinely don't, and I'll tell you so — I wrote a straight piece on selling your house without an agent in Connecticut. It covers where doing it yourself actually works, what AI is genuinely good at now, and what an automated price still misses even somewhere that trades as often as Montville.
Single-family homes in Montville sold at a median of $356,000 in 2025, up from $344,000 in 2024, across 209 sales — up 20% from 174 the year before, the third-highest sales count in New London County. They went at 103.0% of list price in a median of 21 days. Source: SmartMLS Local Market Update, December 2025.
31.43 mills for FY2026-27, up about 8.9%. Most of the Connecticut mill rate changes being reported right now trace back to revaluations. This one is a straight budget increase — Montville doesn't revalue until the October 1, 2026 Grand List. On a $356,000 house assessed at 70% of value, that works out to roughly $7,832 a year. Confirm your own figure with the Montville Tax Collector.
No. Mohegan Sun sits on the Mohegan Tribe's reservation, which is held in federal trust and stays off Montville's property tax rolls entirely. What Montville gets instead is a state grant from the Mashantucket Pequot and Mohegan Fund — $1,446,162 for FY2027, about $79 per resident. That's less per resident than Preston (~$243), North Stonington (~$171) or Ledyard (~$90) get, and none of them host Mohegan Sun.
No. Uncasville is a village and a postal address inside the Town of Montville — same mill rate, same schools, same town government. Montville's own Town Hall has an Uncasville mailing address. Montville's other villages are Oakdale, Chesterfield and Mohegan. If you search only "Uncasville," you'll hide most of Montville's inventory from yourself.
Yes. Montville High School serves grades 9–12 within Montville's own PK–12 district. Neighboring Bozrah, Franklin, Lisbon, Preston, Sprague and Voluntown all send their high schoolers out of town instead, usually to Norwich Free Academy.
Every assessment in town resets to current market value on the October 1, 2026 Grand List, which hits bills in July 2027. Assessments will likely rise and the mill rate will fall to compensate. Whether your own bill goes up or down comes down to whether your assessment moves more or less than the town average — the new mill rate number by itself tells you nothing.
No. Montville sits far outside the 20-mile radius around the former J.J. Mottes Concrete Company in Stafford Springs that defines Connecticut's crumbling foundation program area.
