What it costs to own a home in Merrimack, NH
Beyond principal and interest, the biggest ongoing cost of owning a home in Merrimack is property tax: the 2026 rate is $15.08 per $1,000 of assessed value, about $126 a month for each $100,000 of assessed value. Homeowners insurance, heating, water and septic upkeep and, for condos, association dues come next. Your lender counts taxes, insurance and dues when it figures what you can afford.
Property tax
About $1,508 a year, or $126 a month, for each $100,000 of assessed value; on a home assessed at $500,000, about $628 a month (Town of Merrimack press release, November 5, 2026). Merrimack revalued every property for 2026, which is why the rate is lower than 2025's $22.11; a lower rate does not by itself mean a lower bill. See Merrimack property taxes and records for how to look up any home's assessment.
Homeowners insurance
Your lender requires homeowners insurance with the lender named on the policy, and proof of coverage before closing. Premiums depend on the home (age, roof, heating system, distance to a hydrant), so get quotes as soon as you're under contract. See the NH homeowners insurance guide.
Heating
Heating is a real line in a New Hampshire budget. Ask the seller for a year of fuel or electric bills and how old the system is. The NH home heating guide compares oil, propane, natural gas and heat pumps.
Water, sewer and septic
Town sewer is billed by the town: homes on town sewer pay a flat annual fee that's added to the July and December tax bills. Water is not a town service: public water comes from the Merrimack Village District (MVD) Water Works, and other homes have private wells. Ask whether a home is on MVD water or a well, and on town sewer or septic, because each one changes your costs and your inspection plan.
Trash and recycling
Merrimack has no curbside trash pickup. Household trash and recycling go to the town's Transfer Station and Recycling Facility, which needs a free residential decal. Details are on the New to Merrimack checklist.
Condo and association dues
If you buy a condo or a home in an association, the monthly dues count in the payment a lender uses to qualify you.
One-time costs when you buy
Closing costs, plus New Hampshire's real estate transfer tax: $0.75 per $100 of the price, paid by both the buyer and the seller. Your Loan Estimate lists your costs within 3 business days of applying. See NH closing costs.
Moving from Massachusetts?
New Hampshire has no broad-based tax on wages, though Massachusetts can still tax wages you earn there. The MA vs NH cost calculator compares the two for your situation.
