Mercer County, Ohio Eviction Risk: Very Low

Mercer County's average eviction-risk score of 2.1/10 (Very Low) places it among the more landlord-friendly markets in Ohio eviction laws, ranking 83rd of 88 counties statewide, meaning 82 Ohio counties carry higher risk. Across all 11 cities, landlords generally encounter a stable rental base: average rent sits at $802, rent burden averages 24% of income, and the poverty rate holds at a modest 6.9%. By the numbers, this is a low-friction operating environment for buy-and-hold investors and smaller residential portfolios alike.

That county average, however, spans a meaningful intra-county range of 1.7 to 2.4. Celina, the county seat and by far the largest city at roughly 10,900 residents, sits at the top of that band. Investors treating the entire county as uniform miss the real risk gradient at the city level, which the grid below makes visible.

The cities inside Mercer County

Rockford leads the risk table at 2.4/10, followed by Montezuma at 2.2/10 and Rockford (population roughly 1,000) at 2.4/10. Coldwater, the county's second-largest city at about 4,200 residents, comes in at 2.1/10, essentially matching the county average. These four cities account for the bulk of rental activity in the county and show the range a landlord might encounter moving from one community to the next.

On the lower end, St. Henry scores 2.2/10, Fort Recovery and Maria Stein both score 1.9/10, and Mendon and Chickasaw sit at 1.7/10 to 2.4/10. The spread confirms that risk in Mercer County is genuinely hyper-local: a landlord operating in St. Henry faces materially different conditions than one operating in Celina, even though both sit within the same county boundaries.

State-level laws that apply here

Ohio state law governs every tenancy in Mercer County. Under the Ohio eviction process, the required notice period depends on the termination reason: nonpayment of rent or a material lease violation triggers a 3-day notice (ORC § 1923.04), a month-to-month holdover requires 30 days (ORC § 5321.17), and the end of a fixed-term lease requires no advance notice at all (ORC § 1923.02). Uncontested cases typically resolve in 21 to 45 days; contested cases can stretch to 45 to 120 days. Ohio does not require just cause for termination and state law preempts any local rent-control ordinance, so no city within Mercer County can impose rent caps.

Ohio eviction costs break down into three components: court filing fees of $160 to $250, sheriff lockout fees of $50 to $175, and attorney fees that typically run $500 to $3,000 depending on complexity. Landlords should also note that Ohio requires 24-hour entry notice under ORC § 5321.04, and fair housing complaints route through the Ohio Civil Rights Commission. For more background on statewide rules, the Ohio security deposit limits and Ohio tenant protections guides cover the remaining statutory obligations that apply to every Mercer County lease.

With a renter share of 26.3% and a poverty rate of 6.9%, Mercer County's rental pool is relatively small and financially stable by Ohio eviction laws standards; the city-by-city grid above shows where within the county that baseline shifts.
