A real, disclosed home-value spread

Zillow's own typical home value ran $382,969, with a separately cited seasonally adjusted figure at $351,669, and Ownwell's own median value (tied to its tax research) running $344,700 -- a real, disclosed spread this record does not resolve to one figure.

An above-county-average property tax rate

Cottage Grove's own median effective property tax rate ran a real, disclosed 1.27% this pass -- above Washington County's own 1.17% average and well above the 1.02% national median.

3M's own long-tenured presence supports the local economy

3M's own 1,700-plus-acre Cottage Grove campus, operating since 1947, alongside Renewal by Andersen as a real, named major private employer, anchors the city's genuinely strong manufacturing-and-retail economic base.

Minnesota's 4-bracket income tax applies regardless

Minnesota's real, progressive 4-bracket state income tax (5.35%-9.85%) applies statewide, including in Cottage Grove -- with no local piggyback layer, but a genuine Social Security taxation outlier above an income threshold.
