Why does a two-bedroom cape on the outskirts of Bangor carry a property tax rate nearly four dollars higher, per thousand dollars of value, than an equivalent house a few minutes away in Brewer? The reflex answer is that Bangor is simply the pricier place to own. Bangor has not completed a full citywide revaluation since 1987, so its assessment base is an important part of the comparison.
If you're weighing Bangor against Brewer or Hampden right now, the mill rate you see quoted is real, but it's telling you less than you think. Here's how Bangor's assessment history relates to the gap, and what the delayed revaluation may mean for tax comparisons.
The Numbers on Paper
Line up the current rates for the three towns most buyers cross-shop in this part of Penobscot County, and Bangor looks like the outlier:
| Town | Most Recently Set Rate (per $1,000 of assessed value) | Tax on a $200,000 Assessment |
|---|---|---|
| Bangor | $19.15 | $3,830 |
| Hampden | $17.65 | $3,530 |
| Brewer | $15.40 | $3,080 |
Brewer's rate and Hampden's rate are both set for the 2025-26 fiscal year, straight from each town's assessing office. Bangor's $19.15 figure is the rate the Bangor Daily News reported as current in 2024, where a $200,000 home produced a $3,830 bill and a $400,000 home a $7,660 one. That's still the base the city says it's carrying forward, because the planned replacement with updated values has been delayed again.
Why Bangor's Assessment Base Matters
Bangor hasn't done a full citywide revaluation since 1987. Home values have moved substantially since then, but the assessed values the city uses to calculate tax bills haven't kept pace, which is exactly why the Bangor Daily News noted that homes in the city have been selling for well over their assessed value for years.
That gap matters because of simple math. A town's mill rate and its total assessed value work together to produce enough revenue to cover the municipal, school, and county budget. If the assessed values are stuck decades in the past, undercounting what the properties are actually worth, the rate has to climb higher to raise the same dollars from that smaller, outdated base. Bangor's $19.15 rate should be considered alongside its assessed-value base; the rate alone does not show what a specific property owner will pay.
Bangor's Revaluation Timeline
Bangor's revaluation process has unfolded over several years. Here's the timeline:
- December 2023: The city's Finance Committee authorizes a contract with KRT Appraisal, a Massachusetts-based firm, to conduct Bangor's first full revaluation in nearly 40 years.
- December 2024: KRT begins the two-year revaluation in earnest, starting with roughly 500 properties on Tax Maps 3, 7, 8, 14, and 15.
- June 2025: Data collectors expand to street after street across the city, including Broadway, Stillwater, and Union.
- August 2025: A progress report shows that while three-quarters of properties have been visited, only 17 percent, or 1,459 homes, have actually received an interior inspection. Another 145 owners refused entry, and 204 properties are posted no trespassing.
- June 11, 2026: City Assessor Phil Drew tells the city council the firm has missed its deadline, so the new values won't be ready in time for this year's tax bills after all.
- The workaround: rather than wait on incomplete data, the city will estimate this cycle's values by adjusting last year's numbers, and City Manager Carollynn Lear says the city will use $2.8 million of its $18.8 million unassigned fund balance to soften the impact while everyone waits another year.
Bangor's eventual rate-and-assessment reset remains ahead, making Portland's completed revaluation a useful point of comparison.
What Portland Just Showed Everyone
Portland finished its own revaluation in 2025, and the before-and-after is worth knowing if you're trying to picture what happens once Bangor's eventually lands. Assessed values on Portland's median home jumped 43 percent, and the mill rate fell from $15.01 to $11.98 per $1,000 to offset it. The city didn't get more expensive to own. The rate simply compressed once the assessed base caught up to reality.
A similar pattern is possible in Bangor once its revaluation is completed. A higher assessed value paired with a lower rate can leave a given homeowner's actual bill close to flat, which is consistent with what Assessor Phil Drew told NewsCenter Maine back when the process began: roughly a third of property owners should expect an increase, a third should see little change, and a third could see their bill go down, largely depending on whether their home has been renovated since the last time anyone from the city walked through it.
What This Means If You're Comparing Towns Right Now
If you're cross-shopping Bangor against Brewer or Hampden this year, treat the posted mill rate as half the story. The other half is the assessment ratio, meaning how close a town's assessed values sit to what homes are actually selling for. Bangor's ratio has been drifting for decades. Brewer's and Hampden's rates reflect their own separate assessment cycles, which is precisely why a raw rate comparison across town lines can mislead you. Ask what the assessed value is relative to a realistic sale price before you assume one town's number is the more expensive one.
Two practical points if you're closing on a Bangor property soon. First, the bill you'll actually pay this cycle is still calculated on the holdover base the city carried forward, not the finished revaluation, so budget closer to the $19.15-era math than to whatever number the eventual reset produces. Second, if you're looking at a multi-unit or an investment property, know that KRT's inspection work has included commercial, industrial, and large apartment buildings alongside single-family homes, which means income-producing properties are part of the same reset. If a property has been renovated recently, expect its assessed value, and its eventual tax line in your pro forma, to move more than the citywide average once the new numbers land.
A Few Questions Worth Asking Before You Compare Towns
Will my Bangor property taxes definitely go up once the revaluation lands? Not automatically. City Assessor Phil Drew has said the impact should split roughly into thirds: an increase for some, no real change for others, and a decrease for the rest, largely tied to whether a property has seen recent upgrades that the 1987-era assessment never accounted for.
When will Bangor's new mill rate actually be set? Not until the assessed values are finalized and folded into a tax commitment, and as of the June 2026 delay announcement, that timeline has slipped again. Until then, the city is carrying forward adjusted prior-year values rather than the finished revaluation.
Does this affect duplexes and small multi-family properties, or just single-family homes? It touches all of it. The same revaluation project covers commercial, industrial, and apartment properties, so investors holding rental property in Bangor should expect their assessed values, and potentially their tax lines, to shift once the process finally concludes.
Property tax mechanics rarely make for exciting reading, but they move real numbers on a closing statement and a rental pro forma alike.
