Housing costs above the national figure, below the state figure

Somerville's home values (Zillow's $435,069 typical value; Redfin's $496,000 median sale price) run genuinely above the national median, while running below New Jersey's own $584,681 statewide average.

A real, below-state-average household income

Somerville's median household income ($99,435, 2024) runs a real 4.9% below New Jersey's own statewide figure ($104,294) -- worth weighing directly against the borough's still-above-national housing costs.

A genuinely elevated property-tax burden

Somerville's effective property tax rate (2.581%) runs above both Somerset County's own 2.05% average and New Jersey's nation-leading 1.88% statewide average, producing an estimated $11,046 median annual tax bill on a median-assessed home.

New Jersey's uniform sales tax and graduated income tax

New Jersey's simple, uniform 6.625% sales tax and graduated statewide income tax (1.4%-10.75%) apply in Somerville with no local add-on -- see new-jersey.js for the full statewide structure.
