Investor takeaways for Portsmouth
With only 3.3% gross yield, Portsmouth buyers often rely on appreciation as part of the plan, and a lender will want the ratio to clear without it. With homes this old, a pre-offer inspection is not optional in Portsmouth. A 48% renter share is large enough to keep units leased, so location relative to jobs and schools drives rent more than the market as a whole.
What costs can do to a Portsmouth ratio
Homeowners in Portsmouth paid a median $8,018 in real estate taxes, about 20% above the New Hampshire median of $6,667, an effective rate near 1.16% of home value against 1.66% statewide. Measured against a year of median rent, taxes eat about 36% before any other cost shows up.
