Spring leasing is hot. Portsmouth averages settled at $2,317 this week, with Somersworth at $1,949, Dover at $1,849, and Rochester at $1,296. The biggest week-over-week move came in Dover, where the citywide average ticked up about 1.6% as the first occupied units at the Cochecho Waterfront Development (Cathartes) start to backfill earlier vacancy. Portsmouth softened slightly as more 2BR product hit the market and pushed the mid-tier average down. The headline number to watch for the rest of Q2: HB 631, the new state law forcing urban municipalities to allow multifamily on commercially zoned land by right, takes effect July 1.
Below is the full city-by-city breakdown by unit type, plus active supply. Rochester remains the cheapest entry point on the Seacoast, with studios at $992 and 1-bedrooms at $1,296. At the 3BR level, Dover ($3,223) and Rochester ($2,997) are now both pricing above Portsmouth ($2,815), driven by larger single-family conversions and townhouse inventory in those markets.

- HB 631 will reshape commercial-to-residential underwriting in Portsmouth. Effective July 1, the state mandates that any urban-classified municipality (Portsmouth qualifies under the U.S. Census definition) must permit multifamily and mixed-use development on commercially zoned parcels by right, provided the parcel has municipal water and sewer. That means strip retail, office, and parking lots along Lafayette Road, Woodbury Ave, and the Pease perimeter become viable acquisition targets without going through a special exception. Look for cap rate compression on B-grade commercial as developers reprice based on residential exit value rather than retail NOI.
- Portsmouth's FY26 tax rate landed at $11.51 per $1,000, six cents below the city's adopted budget estimate. Roughly $200M in new property development this fiscal year offset the projected increase by about 41%, which is unusually favorable. For investors running pro formas on Portsmouth multifamily, that's a real swing on PITI: on a $1.2M four-unit, the difference between the projected and actual rate works out to about $72/year, but more importantly signals that the new construction pipeline is doing real work on the tax base. Worth modeling continued growth into your hold-period assumptions.
- Opportunity Zones 2.0 brings fresh census tract nominations and a new rural designation. Under the One Big Beautiful Bill Act, the Governor's office is currently evaluating new OZ tract nominations for 2026. Existing tracts in downtown Rochester and parts of Dover continue to qualify, and the new Qualified Rural Opportunity Zone designation includes a 30% basis boost plus lower substantial-improvement thresholds. If you've got appreciated stock or a 1031-incompatible asset and want to defer capital gains into Strafford County multifamily, this is the window to start lining up Qualified Opportunity Funds.
