Hillsborough County sits firmly in appreciation territory, and the numbers make that plain. At a median home price of $517,338 against median rent of $2,092, the gross rent-to-price ratio comes in at 4.85%, which is thin by any cash-flow standard. The cap rate at current pricing is 3.15%, and when you run a fully leveraged scenario at 6.85% interest with 20% down, the math produces negative $1,352 per month in cash flow and a cash-on-cash return of -13.63%. This is not a market where you buy and collect a check. What the market does offer is 2.49% year-over-year home price appreciation and an appreciation score of 75 out of 100, placing it clearly on the equity-build end of the spectrum. The overall score of 54 and a national percentile rank of 36 out of 1,000 counties suggest a market that is solidly mid-tier nationally, not a standout by any composite measure, but one with a specific use case for the right buyer.
The investor this market suits is either an appreciation buyer who can tolerate negative carry in exchange for price growth, or someone acquiring with a larger down payment to reduce the monthly debt service drag. A cash-flow buyer looking at the raw numbers here will find no path to positive returns without either a well-below-ask purchase or a value-add play that materially lifts rents above the current $2,092 median. The affordability index of 48 and the median household income of $95,112 indicate a market where renters are reasonably qualified but housing costs are stretching them, which puts a ceiling on how aggressively you can push rents. A value-add operator who can acquire below median, force appreciation through renovation, and refinance or sell into a market with demonstrated price growth has the clearest angle here, but the entry price makes that a precise execution game, not a wide-margin one.
New Hampshire's property tax structure deserves serious attention before you build your proforma. The state-average effective rate is 2.18%, which the Tax Foundation flags as very high, and that translates to an estimated $11,278 in annual property taxes on a median-priced asset here. Combined with insurance of roughly $1,190 per year, you are carrying $1,039 per month in tax and insurance alone before you account for mortgage, maintenance, vacancy, or management. That single line item is the primary reason the cash-flow score sits at 43. At 2.18%, the rate is high enough to deserve its own line on your underwrite and to stress-test at a range of values, particularly because the note attached to this data is explicit that actual county and township rates in New Hampshire may differ meaningfully from the state average. Hillsborough County includes municipalities with historically aggressive local tax rates, so pulling the actual mil rate for each target town before committing to a price is not optional due diligence here.
Looking at Hillsborough against its neighbors clarifies where it fits. Grafton County has a rent-to-price ratio of 5.94% and an overall score of 60, making it the most cash-flow-oriented option in the region by a meaningful margin, and at a median price of $413,099 it is $104,000 cheaper per door. Both Strafford County (5.13% rent-to-price, $485,977 median, score of 56) and Merrimack County (4.95% rent-to-price, $470,918 median, score of 56) also score above Hillsborough overall and carry better rent-to-price ratios at lower acquisition costs. Rockingham County is pricier at $599,250 median with a 4.73% ratio and scores the same 54 as Hillsborough, so it offers no real advantage unless proximity to the Massachusetts border justifies a premium for tenant demand reasons. The case for choosing Hillsborough over these alternatives comes down to population scale, at 422,733 it is the largest county in the state, which supports liquidity on the exit and a deeper tenant pool, and to the appreciation score of 75, which is the highest in this group if price growth is the primary objective. If cash flow is the goal, Grafton or Strafford deserves the first look. If you are building equity over a seven-to-ten year horizon and can absorb the carry cost, Hillsborough's population depth and price trajectory make it the more defensible long-term hold.

Hillsborough County in New Hampshire scores 54/100, ranking #482 of 1,000 US counties (top 64%). At 20% down and current rates, a median-priced rental loses about $1352/month; the 4.85% gross rent-to-price ratio doesn't survive debt service. The thesis here is appreciation, value-add, house hacking, or all-cash.
