New Hampshire has a cost of living index of 115 (national average = 100). New Hampshire sits close to the national cost of living average, making the rent vs buy decision fairly balanced and highly sensitive to your specific situation, timeline, and local neighborhood.
At a 3-year horizon, renting in New Hampshire is typically the lower-risk option because the buy premium of $1,687/month has not yet been offset by equity accumulation and appreciation. By year 12, cumulative equity growth and home appreciation generally surpass the total rent premium paid. Beyond 12 years, buying in New Hampshire historically delivers stronger financial outcomes for most households.
New Hampshire has no state income tax, which simplifies the tax picture. The federal mortgage interest deduction and property tax deduction (subject to the $10,000 SALT cap) remain available and can meaningfully reduce the net cost of homeownership.
