Rock County, Wisconsin Eviction Risk: Low

Rock County, Wisconsin eviction laws carries an average eviction-risk score of 3/10 (Moderate) across its 11 tracked cities, but that headline figure understates how much operating conditions vary within the county. City-level scores run from 3.8 to 5, a range wide enough that two landlords with portfolios just a few miles apart can face meaningfully different tenant-turnover dynamics, court-filing frequencies, and rent-collection risk. At the county level, Wisconsin ranks Rock County 2nd of 72 counties for eviction risk, meaning only 1 county in the state carries a higher risk profile. Investors treating this as a routine mid-risk market should look harder at where, exactly, they are buying.

The county's average rent sits at $1,038 per month against an average rent burden of 27% of income, and 34.7% of residents rent rather than own. Those numbers point to a renter base that is functional but financially thin at the margins, a combination that tends to produce episodic non-payment rather than catastrophic portfolio-wide defaults. Seasoned landlords who screen carefully and respond to delinquency quickly can operate profitably here; those who rely on informal management or slow court filings will feel the friction more acutely.

The cities inside Rock County

The two largest cities anchor the high end of the risk range. Janesville, with a population of 66,030, and Beloit, with 36,534 residents, both score 5/10, placing them at the ceiling for the county and firmly in the elevated-risk category statewide. Together they account for the bulk of the county's rental inventory, so an investor building a Rock County portfolio will almost inevitably be concentrated in these two markets unless they actively seek out smaller communities.

Moving down the risk curve, Evansville scores 4.7/10, Footville 4.6/10, and Milton 4.5/10. Edgerton, at 4.3/10 and a population of 6,014, and Clinton, at 4/10, represent a noticeable step down in risk. The lowest score in the county belongs to Orfordville at 3.8/10, a small community of 1,473 residents where the rental market is thin but conditions are comparatively stable. Risk in Rock County is genuinely hyper-local, and city-level scores should drive underwriting decisions more than the county average alone.

State-level laws that apply here

Wisconsin state law under Wis. Stat. § 704 (Landlord and Tenant) sets the procedural framework every Rock County landlord operates within. For non-payment of rent, Wisconsin requires a 5-day notice before filing. Lease-violation cures require 14 days, and no-cause or end-of-term terminations require 30 days. Once filed, an uncontested case typically resolves in 21 to 45 days; contested matters run 45 to 120 days. Total direct costs, excluding lost rent, run from a low of roughly $645 (court filing $95, sheriff $50, attorney $500) to a high of $3,325 (filing $175, sheriff $150, attorney $3,000). Landlords evaluating total exposure should model the full range rather than assume best-case outcomes. The Wisconsin eviction process is fully covered in the site's statewide guide. Wisconsin does not require just cause for non-renewal, and state law preempts any local attempt to impose rent control, so there are no local rent-cap ordinances to track. For a full breakdown of what each step costs, see the Wisconsin eviction costs guide. Wisconsin security deposit limits and Wisconsin tenant protections are also governed at the state level and do not vary by municipality within Rock County.

With a county poverty rate of 11.1% and renters making up 34.7% of households, the risk spread across Rock County's 11 cities is real, and the city-score grid above is the most reliable starting point for underwriting any specific acquisition here.
