New Hampshire Mortgage Calculator
Model your budget in the Granite State. Factor in the "Live Free or Die" tax tradeoff: zero income tax, but punishing 1.89% property taxes and massive winter heating bills.
The "Live Free or Die" Tradeoff
New Hampshire operates on a highly unique financial model compared to the rest of New England. The state proudly levies no general sales tax and no state income tax (on wages). This makes it a haven for high-income earners.
The Catch: Crushing Property Taxes
Because the state does not collect income or sales tax, almost the entire burden of funding public schools, police, and local infrastructure falls squarely on homeowners via local property taxes.
The statewide effective property tax rate averages 1.89%, regularly ranking it in the top 5 highest in the nation. If you buy a $450,000 house, expect to pay $8,500 to $10,000+ per year just in taxes. When you use this calculator, you will see that the tax escrow completely dwarfs the home insurance cost.
The Boston Border Squeeze
The housing market is sharply divided. The median home price sits around $450,000, but Southern New Hampshire (Rockingham and Hillsborough counties, including Nashua and Salem) operates essentially as a Boston suburb.
Thousands of Massachusetts workers commute down I-93 every day. They earn high Boston salaries but live in NH to avoid MA state income tax. This extreme cross-border demand has decimated entry-level inventory in Southern NH, pushing local buyers further north toward Concord or the Lakes Region in search of affordability.
State Assistance: NH Housing
To assist locals competing in this aggressive market, New Hampshire Housing provides excellent mortgage programs for low-to-moderate-income buyers.
- Home First: Provides up to $10,000 in down payment assistance as a forgivable grant. You do not have to pay it back as long as you meet the residency requirements.
- Home Flex Plus: Provides DPA up to 3% of the loan amount as a cash advance, making FHA or Conventional loans much more accessible.
- Homebuyer Tax Credit: Allows eligible buyers to claim an annual federal tax credit of up to $2,000 every year for the life of the mortgage.
Calculating Your NH Budget
Let's calculate a realistic payment for a $450,000 home purchase in Southern NH, utilizing a 10% down payment and a 6.5% interest rate:
- Mortgage Amount: $405,000
- Principal & Interest: ~$2,560/mo
- Property Taxes (1.89%): ~$709/mo
- Home Insurance: ~$92/mo
- Total Payment: ~$3,361/mo
If this home is older and heated by Fuel Oil, you must budget an additional $200-$350/mo annualized just for winter heating costs.
Critical Granite State Inspections
- Arsenic and Radon in Wells: New Hampshire is the "Granite State." Granite bedrock naturally leaches arsenic and radon into groundwater. If buying a home with a private well, a comprehensive water quality test is absolutely mandatory.
- Winterization and Ice Dams: Check the depth of the attic insulation. Poor insulation causes heat to escape and melt roof snow, which refreezes at the gutters forming "ice dams" that tear off shingles and cause interior leaking.
- Septic System Age: Because much of the state is rural or suburban without city sewer, septic systems are standard. Replacing a failed leach field in rocky NH soil can cost $15,000 to $25,000. Always get an independent septic inspection.
Frequently Asked Questions
Are property taxes high in New Hampshire?
Yes, incredibly high. Because New Hampshire has no state income tax and no general sales tax, local municipalities rely heavily on property taxes to fund schools and services. The effective rate averages 1.89%, making it one of the top five highest in the nation.
Why are houses in Southern NH so expensive?
Southern New Hampshire (towns like Nashua, Salem, and Portsmouth) acts as a tax-haven bedroom community for Boston. Thousands of commuters live in NH to avoid Massachusetts income taxes, driving up demand and home prices near the border.
What is NH Housing down payment assistance?
New Hampshire Housing offers the Home First program, which provides a forgivable grant of up to $10,000 for down payment and closing costs for eligible first-time homebuyers.
How much does it cost to heat a house in New Hampshire?
Much like Maine, a large percentage of NH homes rely on Fuel Oil or propane for winter heating. During a severe winter, it is common to spend $2,500 to $4,000+ filling the oil tank to keep an older home warm.
Do I need a private well inspection?
Yes. Outside of the major cities, most NH properties use private wells. The state's granite bedrock naturally leaches arsenic and radon into groundwater, making specialized water quality testing absolutely mandatory before closing.
