Avg Assessed Value is the mean assessed value of single-family homes only (MA property class 101 — excludes condos, multi-family, and apartments). MA law requires assessment at 100% of fair market value. Income Per Capita is total town income divided by population, derived from MA state income tax returns (not Census surveys). It includes wages, investment income, and capital gains, so wealthy towns can have very high figures. The MA median is about $48K. Tax bill rank orders towns by average single-family tax bill, highest to lowest.
Tax & Bond Details
Residential Tax Rate1.73%
Tax as % of Income15.75%(typical)
Tax rate is the effective residential rate (tax bill ÷ assessed value). Tax as % of income measures how much of residents’ income goes to property taxes. The MA median is about 14%; below 10% is low (wealthier towns with high incomes relative to home values), above 16% is above average.
New Growth
$5.7M+0.87% levy growth(typical)
Residential$4.3M
Commercial/Industrial$1.5M
Residential Share74.15%(typical)
New growth measures new taxable value from construction and development (not rising home prices). In Massachusetts, Proposition 2\u00BD limits annual property tax increases to 2.5% of the prior year\u2019s levy. New growth revenue is automatically added on top of this 2.5% base increase \u2014 it does not require a vote. This town’s total levy growth is about 3.4% (2.5% base + 0.87% from new growth). The MA median is about 1.2%; above 1.5% is strong, below 0.8% signals limited development. The residential share (74.15%) shows how much comes from homes vs. commercial/industrial. When most growth is residential, homeowners carry more of the tax burden. More commercial/industrial growth is generally better for homeowners because businesses share the cost.
Municipal Free Cash
$1.4M10.9% of operating budget
