Mercer County, Pennsylvania Eviction Risk: Moderate

Mercer County, Pennsylvania scores 4/10 (Moderate) on the eviction-risk index, an average drawn from 22 tracked cities across the county. That middle-of-the-road figure places it 25th of 67 Pennsylvania eviction laws counties, meaning 24 counties carry higher risk and 42 are more landlord-friendly. For investors sizing up western Pennsylvania eviction laws, the county is workable but not frictionless: an average rent of $826, a rent-burden rate of 28.3%, and a poverty rate of 14.3% create a tenant pool under real financial pressure, and that stress surfaces in elevated eviction exposure in certain pockets.

The intra-county spread tells the more important story. Scores range from 3 to 6.2, a gap wide enough that two properties a few miles apart can represent fundamentally different operating environments. A landlord buying in the lowest-risk corner of Mercer County faces conditions far closer to a stable suburb than to the higher-risk urban cores in the county's northeast. Location discipline matters here more than the county average suggests.

The cities inside Mercer County

The highest-risk address in the county is Farrell, scoring 6.2/10 with a population of 4,199. Sharon, the county's second-largest city at 12,936 residents, is close behind at 6.1/10. Sandy Lake, Reynolds Heights, and Stoneboro each score 5.7 to 5.8, rounding out the upper-risk tier. These cities share characteristics common to higher-risk markets: smaller renter pools under above-average financial strain, which translates to longer vacancy gaps and a higher probability of nonpayment situations reaching the courthouse.

On the lower end, Grove City scores just 3/10, the most landlord-favorable result in the county, with a population of 7,830. Hermitage, the county's largest city at 16,041 residents, comes in at a moderate 5.1/10. Greenville sits at the county average of 4/10. The spread makes clear that risk in Mercer County is hyper-local: sub-market selection, not county-level screening, drives outcomes for landlords here.
