Why are New Hampshire cap rates so tight?
Demand for the buildings is as strong as demand for the units inside them. Boston-area affordability pressure keeps pushing renters north along I-93 and the Everett Turnpike, holding vacancy down and rents up. Every investor can see the same thing, which bids acquisition prices up in parallel.
The vacancy picture is the clearest evidence. New Hampshire's rental vacancy rate was 3.9% in January 2025, according to Census Bureau data tracked by the St. Louis Fed, against the roughly 5% New Hampshire Housing treats as a balanced market. At the tightest point in recent years, the vacancy rate for two-bedroom apartments statewide was measured at 0.6% in early 2023, as documented by the New Hampshire Fiscal Policy Institute.
The practical consequence: if you model a purchase at asking price with market rents and no improvement plan, the math usually comes out thin. Deals that work here tend to have something specific going on: below-market rents on long-tenured tenants, deferred maintenance you can price and fix, an unfinished unit, or a bad management situation.
What has happened to New Hampshire rents?
They have climbed steadily for a decade, and faster than incomes. Statewide median gross rent for a two-bedroom rose 36% in the five years to 2024, with a 3.9% increase from 2023 to 2024 alone, according to New Hampshire Housing's Residential Rental Cost Survey, the authoritative annual dataset for the state's rental market.
HUD's FY2026 Fair Market Rents put the statewide median two-bedroom at $1,855, with Rockingham County highest at $2,194 and Coös lowest at $1,287. That $900 county spread is the single widest variable in NH rental math, and it tracks almost exactly with how far a property sits from the Massachusetts line.
Which NH markets work, and what's the tradeoff?
| Market | What it offers | The tradeoff |
|---|---|---|
| Manchester | Largest city, deepest housing stock, historic triple-deckers, widest range of entry points | Most competition for deals; older stock carries higher operating costs |
| Nashua | Strong cross-border demand from MA commuters; rents trend higher than Manchester for comparable buildings | Low inventory, properties move quickly |
| Concord | Slower-moving market, more transparent pricing, established local property management | Smaller rental pool, less appreciation pressure than the I-93 corridor |
| Commuter towns (Salem, Windham, Londonderry, Derry, Hudson, Pelham, Litchfield, Hooksett) | Steady demand from continued MA-to-NH migration | Entry prices already reflect that demand |
| Rochester, Somersworth, Franklin, Claremont | Lowest entry prices in the developed part of the state | Thinner tenant pools and slower appreciation than the I-93 corridor |
| Coös and the North Country | Cheapest entry in the state, with a 2BR FMR of $1,287 | Thin tenant pool, slower appreciation, harder management coverage |

What does the math actually look like?
Cap rate is net operating income divided by purchase price. The trap is NOI, because first-time underwriting is almost always too optimistic on expenses.
Standard starting assumptions for small New England multifamily:
- Vacancy allowance: 5%, even though actual NH vacancy runs tighter. Underwriting to the tight number leaves no margin.
- Operating expenses: 35%–45% of effective gross income, adjusted upward for older buildings or self-management.
- Property taxes: the line item that decides NH deals. Bedford's 2025 total rate was $16.49 per $1,000 of assessed value. Rates are set annually by the NH Department of Revenue Administration and vary meaningfully town to town, so always pull the current year for the specific parcel.
A worked illustration. A three-unit building at $600,000, units renting at $1,800 each:
- Gross scheduled rent: $64,800/year
- Less 5% vacancy: $61,560 effective gross income
- Less 40% operating expenses: $36,936 NOI
- Cap rate: $36,936 ÷ $600,000 = 6.2%
That is arithmetic on invented inputs. It isn't a projection for any real property. Change the tax rate, the age of the roof, or whether one tenant sits $400 under market, and the answer moves substantially. The method is the point, and the expense ratio matters more than the rent number people tend to lead with.
Run the real numbers before you write the offer
How much does no state income tax actually matter?
More than most out-of-state investors account for. New Hampshire doesn't tax wages or salaries, and the interest and dividends tax was fully repealed as of 2025. Rental income isn't taxed at the state level.
For an investor with a Massachusetts day job, that's a real difference in after-tax return on identical gross rent. It's part of why NH cap rates compress. The after-tax yield is better than the headline number suggests, and buyers price that in.
The offset is property tax. New Hampshire funds services primarily through property taxes, which rank among the highest in the country, and that lands on your NOI every year. A building in a town with an $18 rate and one in a town with a $14 rate are not the same investment at identical rents and purchase price.
That trade is the most underestimated variable I see in out-of-state underwriting.
Is New Hampshire a cash flow market or an appreciation market?
Mostly appreciation, at current pricing. The median cost of a single-family house rose to $535,000 in 2025, an increase of 78.3% from 2019, and stood at $525,000 as of February 2026, per the New Hampshire Fiscal Policy Institute. Between 2024 and 2025, half the state's ten counties recorded median price increases above 5%.
That growth is what compresses cap rates. You're buying into a market where the asset has appreciated faster than rents, which mathematically drives yield down as prices rise.
None of that makes NH a bad market. It means the honest expectation is modest current yield, meaningful equity growth, and a tight rental market that keeps units occupied. If someone tells you a market with sub-4% vacancy and 5.5% cap rates will throw off large monthly cash flow at asking price, ask to see the spreadsheet.
Where does cash flow actually come from here?
Four places, roughly in order of how often they work:
- Below-market rents. Long-tenured tenants at rents set years ago. The gap is visible in the rent roll before you buy.
- Deferred maintenance you can price. A roof, a heating system, unit turns a seller didn't want to handle. Priced correctly, that's a discount rather than a risk.
- Unit count you can add legally. Unfinished basement or attic space, or an ADU where zoning allows. Check the ordinance first.
- Operational fixes. Utilities billed back where the lease allows, better management, reduced turnover.
What generally doesn't work: buying a fully stabilized, fully renovated building at market price and waiting for the numbers to improve.
