Rent vs Own in Rock County, Wisconsin

What This Data Tells Us About Renting vs Owning in Rock County

The median home value in Rock County, Wisconsin is $231,600 with a median annual property tax of $3,703 — an effective rate of 1.60% on the underlying value. At 20% down and a 6.5% 30-year mortgage, the estimated monthly ownership cost (mortgage plus property tax plus insurance) comes to $1,547, versus $1,246/mo for a HUD Fair Market Rent 2-bedroom unit in the same county. On those assumptions, renting is about $301/mo cheaper than owning before accounting for equity build-up or long-term appreciation.

The median household income in Rock County is $75,673, which puts the home-price-to-income ratio at roughly 3.1x — a common affordability yardstick flags ratios above 5x as stretched. Property taxes alone consume 4.9% of median income, versus a 2%–4% national benchmark. These are median-household snapshots, not personalized numbers — your own rent-versus-own math depends on down payment, credit, mortgage rate, how long you plan to stay, and whether you itemize the property tax deduction on your federal return.

This calculator is for informational purposes only and is not tax, legal, or financial advice. Property tax figures come from the U.S. Census Bureau ACS 5-Year Estimates and rent figures come from HUD Fair Market Rents; both describe area medians, not individual transactions. Insurance is estimated at 0.35% of home value annually and closing costs, maintenance, HOA, and PMI are not included. Consult a licensed mortgage, tax, or real-estate professional before making a buy-or-rent decision based on these numbers.
