Rockingham County

Rockingham County sits at the expensive end of New Hampshire's housing market, with a median home price of $619,521 and median rent of $2,538. That produces a gross rent-to-price ratio of 0.049, or roughly 4.9%, which is low enough to make conventional leveraged acquisition math punishing. The model underwrite confirms it: at 6.85% on an 80% LTV loan, the monthly mortgage alone is $3,248, estimated expenses add another $888, and gross rent of $2,538 covers neither. Estimated monthly cash flow is negative $1,597, cash-on-cash return is negative 13.45%, and the cap rate lands at 3.2%. That 3.2% cap is well below most investors' cost of capital, which means this market is not pricing in any yield premium, it's pricing in appreciation. Year-over-year home price growth of 2.93% is real but modest; the appreciation score of 79 out of 100 reflects the county's trajectory more than any single year's number. This is a market where the return thesis lives in the asset, not in the income stream.

That distinction matters for investor fit. A cash-flow buyer has very little to work with here: the cash-flow score is 44 out of 100, the county ranks 459th out of 1,000 nationally (39th percentile overall), and the negative carry is structural, not a quirk of one bad deal. An appreciation buyer or long-term wealth-accumulation investor is a better fit, particularly one with significant equity capital who can reduce or eliminate leverage and tolerate near-breakeven operations while the asset gains value. A value-add operator faces the same entry-price problem; at a $619,521 median, there is limited room for forced equity unless the purchase is meaningfully below market. The affordability index of 46 and median household income of $110,225 are worth holding together: residents here earn well, but at 46 on the affordability index, ownership is still stretched, which supports rental demand from high-income tenants who have not yet crossed into ownership, a demand profile that keeps rents from collapsing even as prices are elevated.

The tax picture is the single most important underwriting variable in this county beyond purchase price. New Hampshire's state-average effective property tax rate is 2.18%, which is very high by national standards, and that rate deserves its own line on every underwrite. On a $619,521 acquisition, annual property tax alone is approximately $13,506, and combined with estimated insurance of $1,425, the monthly tax-and-insurance load is $1,244. That figure eats roughly half of gross rent before a single dollar of mortgage, maintenance, or management is counted. The 2.18% rate is a state-average estimate per Tax Foundation 2024 data, and county or township rates in Rockingham may differ, but directionally this is not a state where investors get a tax-cost tailwind. Any underwrite that uses a national average tax assumption will be materially understated here.

Rockingham's exposure risks are worth naming plainly. The county's overall stability score is 50, middle of the pack, which is not alarming but is not a buffer either. The affordability index of 46 means that if interest rates stay elevated, both owner demand and renter-upgrade paths are constrained, which can cap rent growth. Concentration risk is real in the sense that southern New Hampshire's rental market is heavily tied to its proximity to the Massachusetts border and greater Boston labor market; if that commuter dynamic weakens through remote-work normalization or employer pullback across the state line, demand for high-cost Rockingham rentals is the most exposed tier in the state. No economic anchor data was provided for this county, so that dimension of demand analysis is outside the scope of this summary.

Comparing Rockingham to its neighbors sharpens the investment decision. Hillsborough and Strafford counties both score 55 and 56 overall, essentially tied with Rockingham's 55, but at median prices of $503,490 and $485,977 respectively, they offer materially lower entry costs. Strafford's rent-to-price ratio of 0.0513 is the best of the three, meaning it extracts more income per dollar of asset than Rockingham's 0.0491. Merrimack County at $470,918 and a 0.0495 ratio is similarly more yield-accessible. Grafton County stands out: it scores 60 overall, carries a rent-to-price ratio of 0.0594, and has a median price of $413,099, making it the clearest alternative for an investor who needs better cash-flow proximity. Coos County at $251,611 is the lowest-price option in the comparison set, though no rent data was provided, and a 52 overall score suggests limited upside.

Choose Rockingham over its neighbors when the investment thesis is explicitly appreciation-driven, when the buyer can deploy substantial equity to reduce leverage-induced cash drag, and when the target tenant base is a high-income renter priced out of Boston-area ownership. If the goal is yield, any of the neighboring counties, particularly Grafton or Strafford, will deliver a better rent-to-price ratio at a lower entry point and with a lower absolute tax burden.
