Merrimack County, New Hampshire Eviction Risk: Low

Merrimack County scores 3.8/10 (Low) on average across its 14 cities, placing it among the more landlord-friendly corners of New Hampshire eviction laws. With 8 of the state's 10 counties carrying higher risk scores, Merrimack ranks 9th of 10 statewide, meaning the operating environment here is notably calmer than most of the state. That said, the countywide average masks a wide internal spread: individual city scores run from 3.6 to 4.4, a gap wide enough that two properties 20 miles apart can feel like entirely different markets.

The rental market supports a meaningful investor base. Roughly 39.5% of households rent, the average rent runs $1,366 per month, and the average rent burden sits at 28.9% of income, a figure that leaves most tenants within a workable range but still signals that a job loss or income shock can quickly turn into a delinquency problem. A county poverty rate of 8.5% keeps default risk moderate rather than severe for most sub-markets.
