Seabrook, NH Real Cost: Home Prices and Taxes

How New Hampshire Pays for Itself: No Income Tax, No Sales Tax

New Hampshire levies no state income tax on wages or salaries and no general state sales tax. Town and county government, the public school system, and local services are funded almost entirely through property tax bills rather than a mix of tax types, the same structural backdrop behind every New Hampshire market this site has priced out.

In most New Hampshire towns, the school portion of that property tax bill runs roughly twice the size of the town-government portion. Seabrook is a genuine, sourced exception: a New Hampshire tax-rate ranking tool (joeshimkus.com, citing 2023 data) found Seabrook's town-rate and school-rate components running roughly equal to each other, a structurally unusual split. The most plausible explanation is that nuclear-plant tax revenue is substituting for what would otherwise be a school-tax-dominated structure, but that underlying cause was not independently confirmed and should be read as a reasonable inference, not a settled fact.

What a Seabrook Home Actually Costs: Below Rye, Close to Hampton

Ask what a home costs in Seabrook and the answer again depends on the source. Zillow's Home Value Index, as of a June 30, 2026 snapshot, puts Seabrook's typical home value at $669,842, up 2.3% year over year, with 14 active listings. The Census Bureau's 2020-2024 American Community Survey estimate puts Seabrook's median home value at $443,500, over $225,000 lower.

That gap is the same methodology-driven pattern this site has documented in Hampton and Rye: Census/ACS figures reflect assessed and reported values across the full housing stock, while Zillow's index tracks current-market asking and sale activity. Present Seabrook home values as roughly $443,500 by Census measures and roughly $669,842 by Zillow's current index, not as one clean number.

Set against its two already-documented neighbors, Seabrook's values run below Hampton's own figures (a Zillow value of $618,203 as of a March 2026 snapshot) and far below Rye's ($1,294,369 by Zillow, more than triple Seabrook's Census figure). The two snapshot dates are not identical, so treat the Hampton comparison as directional rather than a precise same-day figure. That ordering lines up with Seabrook's income profile: a $84,349 median household income and a 12.1% poverty rate, both meaningfully below Rye's roughly $137,969-$140,655 and somewhat below Hampton's own figures, consistent with Seabrook being a genuinely more attainable, middle-market Seacoast price point rather than a discount one.

Neither figure isolates Seabrook Beach's oceanfront housing stock from inland Seabrook, and a specific, separately sourced beachfront price premium was not confirmed in this research. A clean, current Redfin median sale price or days-on-market figure for Seabrook or Seabrook Beach specifically was also not independently pulled; a fetch attempt returned migration data rather than pricing. Anyone budgeting around a specific Seabrook purchase should pull redfin.com's Seabrook and Seabrook Beach city pages directly.

The Tax Rate: Why the Nuclear Plant Does Not Make Seabrook Cheap

Seabrook's 2025 property tax rate runs $12.40 per $1,000 of assessed value, per nhfinehomes.com's property tax rate comparison page, updated December 2025. That is down substantially from a 2023 rate of $15.09 per $1,000 cited by a separate Seabrook-focused analysis (seabrook.substack.com), a decline plausibly tied to a town-wide property revaluation, a common New Hampshire mechanism where a reval raises assessed values and mechanically lowers the nominal rate, rather than necessarily a spending cut. That specific cause was not independently confirmed and should be verified with Seabrook's own Assessing office before being stated as fact.

Here is the part worth naming directly, because it runs against the intuitive assumption: Seabrook's $12.40 rate sits close to Hampton's $12.61 by the same source, not dramatically lower. It is meaningfully lower than Hampton Falls' $14.80 and North Hampton's $13.45, but still notably higher than Rye's roughly $8.37-$8.66. A nuclear plant contributing a quarter to a third of a town's entire tax levy does not automatically translate into the lowest tax rate on the Seacoast, because Seabrook's own school and municipal costs are also comparatively high for a town its size.

The plant's contribution itself is real and substantial. Per New Hampshire Bulletin's March 2026 reporting, quoting Seabrook Town Manager Bill Manzi, NextEra Energy's tax payments represent roughly 25-30% of Seabrook's total tax levy, a very large share of town revenue concentrated in a single taxpayer, genuinely unlike Hampton's or Rye's tax base. Because the plant's assessed value has swung dramatically over the years, once valued above $2 billion, falling below $1 billion at its lowest point, Seabrook has for years negotiated pre-set, multi-year tax agreements with NextEra rather than fighting an annual assessment dispute. The most recent agreement, covering fiscal years 2024-2026, totals $45 million over three years, a 12.5% increase over the prior three-year deal and $9 million higher than the deal from six years earlier.

Community sentiment about that arrangement is genuinely mixed, not uniformly positive. The same New Hampshire Bulletin reporting quotes Town Manager Manzi describing the plant as woven into the fabric of the community, while other residents quoted in the same piece wanted clearer proof of direct benefits, such as lower energy costs, or more health and safety testing before treating the relationship as an unambiguous win. Present the plant's tax role as a real, economically significant, and genuinely debated part of town life, not as a settled bargain.

This research relied on secondary aggregators (nhfinehomes.com and seabrook.substack.com) rather than the New Hampshire Department of Revenue Administration's own official municipal tax rate report. Anyone budgeting around a Seabrook purchase should re-verify the current rate directly against revenue.nh.gov or Seabrook's own Assessing office at seabrooknh.info before treating $12.40 per $1,000 as a locked-in current figure.

Flood Exposure and the Plant Sits in the Same Floodplain

A Rockingham Planning Commission hazard-mitigation assessment modeled Seabrook under three sea-level-rise scenarios, 1.7 feet, 4.0 feet, and 6.3 feet by 2100. At the low-end 1.7-foot scenario, roughly 85% of Seabrook's current 100-year floodplain would be affected, rising to roughly 94% at the high-end 6.3-foot scenario. At that high-end scenario, approximately 882 parcels valued at $336 million face flood risk, a genuinely strong, citable exposure figure.

The infrastructure the same report names as at risk includes sewage pump stations, Seabrook's Elementary-Middle School, the wastewater treatment plant, and, notably, the NextEra Seabrook Station facility itself. That is a planning-level infrastructure-vulnerability data point, not a safety finding about the plant, but it is a real, sourced fact that even the plant's own site sits in an area assessed for sea-level-rise and flood exposure planning. Tidal wetlands are the most significant natural resource at risk, with 235.3 to 268.6 acres of salt marsh affected across the modeled scenarios, and Route 1A and Route 286 are both named as highly susceptible to inundation.

A Seabrook-specific historical storm-damage account, dollar figures or dated events comparable to Hampton's documented nor'easter history or Rye's January 2024 seawall damage, was not found in this research. Given Seabrook's shared coastline and shared Hampton-Seabrook Estuary with Hampton, similar nor'easter and high-tide flooding exposure is a reasonable assumption, but do not assert Seabrook-specific damage totals or insurance-claim figures without further primary-source verification through NH DES's high-tide-flooding report or FEMA's Flood Map Service Center.

Schools and the Regional Trade-Off

Seabrook operates its own Seabrook Elementary School and Seabrook Middle School, both part of SAU 21, the same school administrative unit shared with Hampton, Hampton Falls, North Hampton, and South Hampton. Seabrook does not operate its own public high school; Seabrook students attend Winnacunnet High School in Hampton, the same regional high school this site's Hampton Beach coverage already profiles in depth (a Niche.com grade of B+, 993 students, and a 91% graduation rate). The exact tuition or attendance arrangement between Seabrook and SAU 21 for that high school relationship was not independently pulled in this research and should be confirmed directly with sau21.nh.gov before citing a specific dollar figure.

A Practical Checklist Before You Rely on Any Number Here

First, do not anchor to a single home-value figure. The Census Bureau's $443,500 and Zillow's $669,842 are two different kinds of numbers from two different sources, and both still land below Hampton's comparable figures and far below Rye's. Pull a current Redfin or MLS figure for Seabrook and Seabrook Beach specifically for a third, more current data point; that was not independently fetched in this research.

Second, verify the $12.40-per-$1,000 tax rate directly, and do not assume the nuclear plant's roughly 25-30% share of the tax levy means Seabrook is the cheapest option on the Seacoast. It is not: the rate sits close to Hampton's and well above Rye's. Confirm the current figure with revenue.nh.gov or Seabrook's own Assessing office before budgeting around it, and ask directly about the town's multi-year NextEra tax agreement, which currently runs through fiscal year 2026.

Third, treat several related figures as open gaps rather than settled facts: a comprehensive FEMA flood-zone parcel breakdown specific to Seabrook, a Seabrook-specific historical storm-damage chronology, a specific Seabrook Beach oceanfront price premium, and the exact tuition arrangement between Seabrook and Winnacunnet High School were all flagged in this research as unconfirmed.

Confirm every figure on this page directly with the Town of Seabrook, the U.S. Census Bureau, FEMA's Flood Map Service Center, the New Hampshire Department of Revenue Administration, and a New Hampshire-licensed real estate agent or tax professional before relying on it financially. Nothing here is tax, legal, or financial advice.
