Harford County, Maryland Eviction Risk: Elevated

Harford County carries a county-wide average eviction-risk score of 5.7/10 (Elevated) across its 16 cities, a reading that tells landlords and investors operating anywhere in this Maryland eviction laws suburb to keep compliance and tenant-screening disciplines tight. The county's 205,141 residents skew heavily toward ownership: just 22.1% of households rent, and average monthly rent runs $1,654, with renters spending an average of 30.9% of income on housing. Statewide, Harford ranks 19 of 24 Maryland eviction laws counties by risk, meaning 18 counties carry higher risk and only 5 are more landlord-friendly, placing Harford in the lower-risk third of the state even though its absolute score remains firmly in High territory.

That High designation is not uniform across the county. Individual city scores span from 5.3 to 6.5, a spread of 1.6 points that has real operational consequences. A portfolio concentrated in the highest-risk pockets faces materially different conditions than one anchored in the county's quieter corridors, so location selection inside Harford matters as much as the county-level headline.

The cities inside Harford County

The highest-risk addresses in Harford are led by Perryman (6.5/10), the only city at the county ceiling. Behind it sit Aberdeen (5.8/10), with a population of 17,298, and Riverside (5.3/10). Edgewood (6.1/10), home to roughly 24,922 residents, and Havre de Grace (5.6/10) round out the upper tier. These five markets carry the most concentrated eviction risk in the county and warrant the closest scrutiny on applicant income stability and lease terms.

Further down the risk ladder, Bel Air North (5.7/10), Bel Air (5.5/10), and Fallston (5.5/10) sit meaningfully below the county average, and the lowest city score in the county reaches 5.9. Risk in Harford is genuinely hyper-local: two properties a few miles apart can differ by nearly a full point, which is why city-level data should drive underwriting decisions rather than the county average alone.
