Hillsborough County, New Hampshire Eviction Risk: Moderate

Hillsborough County scores 4/10 (Moderate) on the EvictionRiskMap scale, making it the most landlord-friendly county in New Hampshire eviction laws, ranking 10th of 10 counties statewide, with 9 of the state's 10 counties carrying higher risk. That county-wide average, however, papers over a meaningful intra-county spread: individual city scores run from 3.6 at the low end to 6.1 at the high end, a gap wide enough to move a property from genuinely comfortable operating territory to a market demanding serious diligence. Landlords evaluating Hillsborough County as a whole are looking at a favorable headline but a mixed reality on the ground.

The county's average rent of $1,618 per month and an average rent burden of 29.4% suggest tenants here are spending a material share of income on housing, which can translate to payment stress during economic disruptions. A renter share of 45.6% across the county averages there is a broad rental base to work with, but also more households for whom a financial shock can quickly become an eviction risk. Operating here under New Hampshire law is workable, but landlords should know exactly which city they are entering before committing capital.

The cities inside Hillsborough County

The highest-risk city in the county is Greenville, scoring 6.1/10, followed closely by Peterborough at 6.0/10 (population 2,539). Milford scores 5.9/10 with a population of 8,956, and Hudson comes in at 5.8/10 with 7,469 residents. East Merrimack, Pinardville, and Bennington also score 5.9/10. These smaller communities, while not large markets, represent the pockets of the county where landlord exposure is meaningfully higher than the countywide average suggests.

Contrast those figures with the county's two population anchors. Manchester, the largest city at 115,643 residents, scores just 3.7/10, and Nashua, with 91,294 residents, scores 3.6/10, the lowest in the county. These two cities account for the bulk of the rental stock and pull the county average down considerably. Investors concentrating on the two urban cores are operating in the least risky environments Hillsborough County offers, while those targeting smaller outlying towns are working in a materially different risk environment. Risk here is genuinely hyper-local, and city-level scores matter far more than the county headline.

State-level laws that apply here

Every property in Hillsborough County is subject to New Hampshire state law under RSA § 540 (Actions Against Tenants). For nonpayment of rent, landlords must serve a 7-day notice before filing. Lease violations and end-of-term no-cause terminations each require a 30-day notice. Once a case is filed, uncontested proceedings typically resolve in 30 to 50 days; contested matters can run 60 to 120 days. Court filing fees range from $130 to $195, sheriff lockout fees add $30 to $125, and attorney fees typically run $500 to $2,500 depending on case complexity. Understanding the New Hampshire eviction process in full is worth doing before acquiring here, since the timeline and cost exposure at the contested end can be substantial.

New Hampshire does not require just cause for eviction and has no statewide rent cap, leaving landlords with meaningful flexibility on lease terms and pricing. One notable protection: source of income is protected under state law, meaning landlords may not decline applicants solely on the basis of rental assistance vouchers. For a full breakdown of what landlords owe at move-out, see the guide to New Hampshire security deposit limits. The New Hampshire Commission for Human Rights enforces fair housing obligations, and retaliation protections for tenants are codified under RSA § 540:13-a, so documented records of any adverse action are essential.

With an average poverty rate of 8.7% and renters making up 45.6% of households across the county, the risk picture varies sharply by community, as the city grid above shows for all 18 cities scored in Hillsborough County.
