For years, people hoping to buy a single-family home in Portsmouth have faced one of New Hampshire’s most expensive and supply-constrained housing markets.
The latest 2026 housing data suggests that market is beginning to look different. Through August 2026, Portsmouth recorded 91 single-family closed sales, compared with 118 during the same period in 2025. That represents a 22.9% decline in home sales.
At the same time, the city's year-to-date median single-family sales price declined 8.4%, from $955,000 during the first eight months of 2025 to $875,000 in 2026.
For people considering relocating to Portsmouth or the New Hampshire Seacoast, however, another number may be even more significant: inventory increased 36.7% from a year earlier.
The combination of fewer sales, lower year-to-date median prices and more homes for sale suggests Portsmouth is moving differently from New Hampshire's broader housing market.
Portsmouth Home Sales Are Down Nearly 23%
Through August, Portsmouth recorded 91 single-family home sales, down from 118 during the same period last year.
That 22.9% decline is notable because New Hampshire has generally continued to experience strong housing demand despite elevated home prices and borrowing costs.
Portsmouth's pending sales also declined.
There were 94 pending single-family sales through August, compared with 124 during the first eight months of 2025—a decrease of 24.2%. Pending sales represent homes that have gone under contract but have not yet closed, making them another useful measure of current buyer activity.
Together, the decline in closed and pending transactions indicates considerably less sales activity in Portsmouth during the first eight months of 2026.
Portsmouth Median Home Price Falls 8.4%
Portsmouth's year-to-date median sales price also moved lower.
The median price for single-family homes sold through August was $875,000, compared with $955,000 during the same period last year. That's an 8.4% decline. The median list price declined as well, falling 4.1% year to date from $995,000 to $954,500.
For relocators, those numbers may make Portsmouth worth another look—particularly for buyers who previously considered the city too competitive.
However, a declining median sales price does not mean that every Portsmouth home has lost 8.4% of its value.
The median reflects the midpoint of the homes that actually sold. Changes in the size, location, condition and price range of properties sold can substantially affect the number, especially in a relatively small market such as Portsmouth.
Inventory Jumps Nearly 37%
Perhaps the most important development for buyers is the increase in available homes.
Portsmouth had 41 single-family homes for sale at the end of August 2026, compared with 30 a year earlier.
That's a 36.7% increase in inventory. Months of housing supply increased even more dramatically, rising
from 1.9 months to 3.5 months.Months of supply estimates how long the existing inventory would take to sell
at the current sales pace if no additional properties entered the market.
Portsmouth still does not have enough inventory to clearly characterize it as a buyer's market. But 3.5 months of supply represents a meaningful improvement from the exceptionally tight conditions buyers experienced when fewer homes were available.
For someone relocating from Massachusetts, Connecticut, New York or elsewhere, that can mean something very practical: more choices.
Homes Are Taking Slightly Longer to Sell Year to Date
Another indicator points toward a gradual shift. Portsmouth single-family homes that sold during the first eight months of 2026 spent an average of 34 days on the market, compared with 30 days during the same period last year.
That's a 13.3% increase. Four additional days may not sound significant, but when combined with rising inventory and declining transaction activity, it provides another indication that some of the urgency that characterized Portsmouth's recent housing market may be easing.
For buyers, additional market time can provide more opportunity to evaluate a property rather than feeling compelled to make an immediate decision.
August Shows Why Buyers Should Look Beyond One Month
Portsmouth's August results also demonstrate why housing trends should be evaluated over longer periods.
During August alone, 15 single-family homes closed, up from 13 in August 2025.
The monthly median sales price actually jumped to $963,000, compared with $790,000 a year earlier.
Meanwhile, pending sales fell from 18 to 10. Those seemingly contradictory numbers are possible because Portsmouth
has a relatively limited number of monthly single-family transactions. A handful of higher-priced or lower-priced properties can substantially affect the median in any individual month.
That's why the year-to-date numbers provide useful additional context. Through eight months, Portsmouth has experienced fewer closed sales, fewer pending sales, a lower median sales price and longer average market times, while August inventory was substantially higher than a year earlier.
Portsmouth Sellers Are Still Getting Close to Asking Price
There is another important piece of the story. Portsmouth's changing market has not translated into widespread evidence of distressed selling. Year to date, sellers received approximately 98.1% of their original list price.
During August, sellers received approximately 97.1%. That means correctly priced properties can still command prices relatively close to their original asking price.
For relocators, the takeaway is not that Portsmouth has suddenly become a bargain market.
Instead, buyers may have more opportunities to evaluate individual listings and potentially negotiate where a property has been overpriced, needs improvements or has remained on the market.
Portsmouth Remains One of New Hampshire's More Expensive Markets
Even after the decline in its year-to-date median sales price, Portsmouth remains an expensive place to purchase a single-family home.
A median of $875,000 places the city well above New Hampshire's statewide median.
But Portsmouth also offers a combination of characteristics that is difficult to duplicate elsewhere in the state.
Its walkable downtown, restaurants, shops, historic architecture, arts and cultural amenities, waterfront setting and proximity to New Hampshire's beaches have long attracted residents to the Seacoast.
Portsmouth also provides access to Interstate 95, connecting residents with southern Maine and Massachusetts.
Those qualities help explain why demand for housing in the city has historically remained strong even at comparatively high price points.
Is Portsmouth Becoming a Buyer's Market?
The current numbers suggest greater balance, but they do not establish that Portsmouth has become a buyer's market.
The city had 3.5 months of single-family housing supply in August, up substantially from 1.9 months a year earlier.
That's meaningful progress for buyers, but it remains below the roughly five-to-six-month range commonly associated with a balanced housing market.
The more important development is the direction Portsmouth is moving. Inventory is up 36.7%. Year-to-date closed sales
are down 22.9%. Pending sales are down 24.2%.The year-to-date median sales price is down 8.4%.
Average days on market are up 13.3%. Taken together, those indicators show a Portsmouth market with more supply and less transaction activity than buyers encountered during the same period last year.
What Portsmouth's Changing Market Means for Relocators
For someone planning to move to New Hampshire, Portsmouth's housing shift could be particularly important.
During periods of extremely limited inventory, buyers may have had very few properties to choose from within the city. That could make it difficult to compare neighborhoods, home conditions and prices before submitting an offer.
Increasing inventory changes that equation.
Relocators may have more opportunities to compare properties and potentially expand their searches beyond whatever home happens to be available at a particular moment.
Buyers should still evaluate each property individually. Desirable homes that are appropriately priced can attract strong interest regardless of broader market statistics.
But buyers may discover that not every Portsmouth listing requires the same strategy that was necessary during the most competitive years of New Hampshire's post-pandemic housing market.
Portsmouth Is Moving Differently From New Hampshire Overall
Portsmouth's shift is particularly noteworthy because New Hampshire continues to face a statewide housing shortage.
Earlier this summer, the New Hampshire Association of REALTORS specifically identified Portsmouth as an example of how local markets can diverge significantly.
Through June, Portsmouth's year-to-date single-family median price was already down 12.5%, while Nashua's was up 8.3%.
NHAR noted that local markets were evolving differently depending in part on available inventory. The August numbers reinforce that point.
A statewide seller-favored housing market can exist at the same time that individual cities experience increasing inventory, fewer sales and more negotiating room.
The Bottom Line for People Moving to Portsmouth
For prospective Portsmouth homebuyers, the 2026 housing data tells a different story than the assumption that every desirable New Hampshire community is becoming more expensive and more competitive.
Portsmouth remains an expensive and highly desirable Seacoast community. But its housing market is showing measurable signs of rebalancing.
With closed sales down nearly 23%, pending sales down 24%, the year-to-date median price down 8.4% and inventory up nearly 37%, buyers have reasons to watch Portsmouth closely.
For relocators who previously ruled out Portsmouth because of limited inventory or intense competition, 2026 may be an appropriate time to take another look at what is available.
The larger lesson for anyone moving to New Hampshire is straightforward: statewide housing headlines only tell part of the story.
In 2026, some of the most important opportunities for relocating buyers may be found by looking at New Hampshire's housing market one community at a time.
