The New Hampshire Seacoast housing market is experiencing a transformation as we move through September 2025. Based on the latest August data, buyers are finding themselves in a notably different landscape than they faced just a year ago. There are still plenty of challenges in the housing market, but there are also evolving opportunities,
Here’s everything you need to know about the New Hampshire Seacoast housing market as we move into the fall.
Inventory is Finally Rising After Years of Scarcity
The most encouraging news for buyers is the significant increase in available homes. According to federal data, active listings in New Hampshire jumped 19.6% from August 2024 to August 2025, rising from 2,705 to 3,235 homes. This marks a meaningful shift from the extreme inventory shortages that defined the post-pandemic years.
To put this in perspective, New Hampshire hit its modern inventory low point in February 2022 with just 873 active listings statewide.
We’re still well below the pre-pandemic norm of 5,000 to 9,000 listings that buyers enjoyed from 2016 to 2019. However, the steady climb over the past three years signals a return toward market balance.
For single-family homes specifically, inventory increased by 22.8% year-over-year, with 2,569 homes available in August 2025 compared to 2,092 the previous year. This translates to 2.5 months of supply. That’s up from 2.1 months in 2024—giving buyers more choices and time to make decisions.
Seacoast Prices Continue Their Premium Trajectory
The Seacoast region, encompassing Rockingham County, continues to command the state’s highest prices. Based on the most recent New Hampshire housing market data (from August 2025), the median single-family home price reached $689,000. That’s a substantial 7.7% increase from the $640,000 median in August 2024.
This premium pricing is now common in the area, which has a lot of appeal for homebuyers. A combination of coastal access, proximity to both Boston and Portland, and a high quality of life draws buyers from across New England.
September 2025 NH Seacoast Housing Market: Days on the Market
Interestingly, while Seacoast prices rose faster than the state average, homes actually sold more quickly.
Days on market in Rockingham County dropped from 23 days in August 2024 to just 19 days in August 2025. a 17.4% decrease that suggests strong underlying demand despite higher prices.
Statewide, the picture is more moderate. Single-family home prices increased 2.8% to a median of $550,000, while condominiums saw a modest 1.7% rise to $415,000. These gentler price increases indicate the market is finding more sustainable growth patterns after the dramatic surges of 2020-2022.

More Homes Are Coming to the Seacoast Housing Market
New listings provide another positive indicator for buyers.
In New Hampshire, 11.1% more single-family homes came to market in August 2025 compared to the previous year. The Seacoast led this trend with new listings jumping 19.8%, as 333 homes entered the market compared to 278 in August 2024.
This increased listing activity suggests sellers are gaining confidence in the market’s stability and their ability to secure their next home. For buyers, it means fresh options appearing regularly rather than competing for the same limited inventory month after month.
Buyer Competition is Moderating Somewhat
While the market has become more buyer-friendly, competition hasn’t disappeared entirely. Pending sales—homes under contract but not yet closed—increased 20.9% statewide for single-family homes, indicating continued strong buyer interest.
However, the nature of competition is evolving. Buyers are no longer routinely paying above asking price. Across New Hampshire, homes sold for 99.9% of their list price in August 2025, down from 100.8% the previous year. In the Seacoast, this figure was 99.7%, up slightly from 99.0% but still below the asking price wars of recent years.
Days on market have increased modestly statewide—from 23 to 25 days for single-family homes—giving buyers more time to conduct inspections, secure financing, and make thoughtful decisions.
Affordability Remains a Challenge in the NH Seacoast Housing Market
Affordability is still a big challenge for New Hampshire homebuyers. According to a recent report by Business NH Magazine, the state’s housing affordability index was 59 in February 2025. That means “a buyer earning the median household income has only 59% of the money needed to qualify for a mortgage on a median-priced single-family home.”
The numbers in the NH Monthly Indicators report released by New Hampshire Realtors indicate that the index dropped to just 53 in June of 2025. It has risen to 55 as of August, but has stayed low for the past three years.
The market continues to favor sellers as affordability stays historically low. The good news is that conditions are gradually becoming more balanced as inventory slowly increases and homes spend slightly more time on the market compared to pandemic-era lows.

As we progress through September 2025, buyers are operating in a market that’s more balanced than at any time since before the pandemic. You’ll find more choices, have more time to decide, and face fewer intense bidding wars.
However, you’ll also encounter higher prices and affordability challenges that require careful financial planning.
Our Advice for Buyers and Sellers
Our advice for Seacoast buyers right now: Take advantage of the increased inventory to be selective about location, condition, and features.
You should have a few more options than in previous years, so don’t rush into the first property you see. Work with your lender to understand exactly what you can afford, including the long-term implications of current interest rates.
Our advice for Seacoast sellers considering a move: The combination of rising inventory, continued buyer demand, and current prices creates a favorable environment for home sales. You’re likely to receive fair market value for your home while having more options for your next purchase.
