Rental property investing in New Hampshire: cash flow, taxes, and what to expect

The New Hampshire setup, at a glance

New Hampshire sits at roughly 2.18% effective property tax, which matters more than most new investors realize. On a $380k-$510k Manchester property, that's about $8,284/year in taxes alone - call it $690/month before you've paid anything else. Run the rental cash flow calculator with that line item baked in or your projection will look better than reality.

Eviction stance here is balanced. Balanced. 7-day pay-or-quit, FED action 10-21 days. That timeline directly affects your vacancy assumption: in balanced-friendly states like New Hampshire, you can underwrite 5-7% vacancy on B-class properties; in slower states you'd want 8-10%.

Where the math actually pencils

Manchester - $380k-$510k for typical SFR, $1,750-$2,250/mo for 2-3BR rents. MA-spillover, no income tax draws.

Nashua - $440k-$580k for typical SFR, $1,900-$2,400/mo for 2-3BR rents. Boston commuter market.

The 1% rule (monthly rent >= 1% of purchase) is a smoke test only, but it filters fast: a $440k-$580k property in Nashua renting at the high end (2,400/mo) clears 0.8-0.9% in most cases, so you're already in the "needs the rest of the math to be tight" zone before vacancy + capex + management.

New Hampshire-specific things that bite

No state income tax, no sales tax - that's the draw. Property tax is high to compensate. Inbound MA migration is strong.

A few cash-flow-killer line items that catch out-of-state buyers in New Hampshire:

• Property tax escrow. At nearly 2% effective, this is the single biggest expense after debt service in many New Hampshire deals.
• Insurance. Standard hazard policies are still reasonable here, but ask about wind/hail riders depending on the specific zip.
• PM costs. 8-10% of collected rent is typical. On a $1900/mo property that's $171-190/mo - works out to about a month of vacancy each year.

What "good enough" looks like in New Hampshire

For a stabilized buy-and-hold in New Hampshire, the rule-of-thumb deal targets most investors I see are:

• Cap rate: 6%+ on the actual NOI (not the broker's pro forma). Below 5% and you're paying for appreciation, which is fine if that's your thesis.
• Cash-on-cash: 8-10% minimum at year 1 with 20-25% down. 12%+ is solid for the work.
• DSCR: 1.25+ if you're using a DSCR loan. Lenders increasingly want 1.2 as a floor, 1.25 to clear comfortably.
• Reserves: 6 months of PITI. New Hampshire's slower eviction process means you may need 8-9 months of reserves in a worst-case turn.

The play that works here

New Hampshire has tilted toward appreciation rather than cash flow in most major metros. Cash-flow seekers usually need to look at secondary cities or accept lower CoC for the appreciation thesis.

Run your specific deal through the rental calculator with the state's effective tax rate (2.18%), realistic New Hampshire insurance quotes, and 8-10% PM. If it still pencils after that, you've got a deal.
