Dover's single-family market is giving off two signals that look like they contradict each other. In September 2026, the homes that sold spent a median of 17 days on the market, down from 37 days in September 2025. Over the same stretch, the number of homes for sale rose from 35 to 54, and months of supply climbed from 1.8 to 3.2, according to the New Hampshire REALTORS® Local Market Update for Dover.
Both numbers are accurate, and they don't actually conflict. They describe two different groups of houses. Days on market until sale is calculated from homes that closed. Inventory counts the homes still waiting. In fall 2026, Dover has a well-priced group that sells about as quickly as it ever has, plus a growing group that doesn't sell. For anyone house hunting this fall, that second group is where the room to negotiate is.
The Inflow Stayed Flat. The Outflow Slowed.
A rise in inventory usually brings to mind a wave of new listings. That's not what happened in Dover. Through September 2026, the city had 231 new single-family listings, nearly the same as the 235 it had through September 2025. Closed sales over the same nine months fell from 175 to 151, and pending sales fell from 191 to 165.
So about as many homes came to market, and fewer of them went under contract. The difference stayed on the market. The September snapshot shows the same thing. That month had 29 new listings against 28 a year earlier and exactly 25 pending sales in both years, yet the stock of homes for sale was 19 homes deeper.
Because those leftover homes never close, they never show up in the days-on-market figure. The 17-day median describes only the homes buyers agreed to pay for.
Four Months of the Same Pattern
A single month of data in a city with a couple dozen closings can mislead. Dover had 24 single-family closings in September 2026, and NH REALTORS® itself warns that percentage changes "can sometimes look extreme due to small sample size." The monthly reports from June through September show this isn't a blip:
| Month (2026) | Homes for sale | Months of supply | Median days to sale | Pending sales | Median sale price | % of original list received |
|---|---|---|---|---|---|---|
| June | 38 | 2.1 | 13 | 28 | $604,750 | 101.5% |
| July | 46 | 2.7 | 22 | 19 | $667,500 | 94.9% |
| August | 51 | 2.9 | 17 | 29 | $660,000 | 99.4% |
| September | 54 | 3.2 | 17 | 25 | $647,500 | 99.1% |
Inventory went up every single month. Days to sale moved around in a narrow band, between 13 and 22. Pending sales went up and down with no trend. A rising stock of homes alongside a steady pace for the ones that sell is what two markets look like.
July stands out. Days to sale rose to 22, pending sales dropped to 19, and sellers who closed got 94.9% of their original list price, the only month of the four under 99%. In June, by comparison, sellers got 101.5%. July is the clearest picture of what happens to a Dover listing that misses. It takes longer, and the price drops before a buyer commits.
What the Price Figures Say About the Leftover Homes
The September report includes one more gap. Dover's median list price was $645,000, down 13.4% from $744,450 in September 2025. The median sale price hardly moved, at $647,500 compared with $652,000.
The report tracks these as separate measures, so it would be a stretch to treat them as one story. Still, together with the inventory trend they show that buyers in fall 2026 are paying about what they paid last fall, for the homes they choose to buy. The year-to-date median through September was $620,000, up 10.7% from $560,000. That's a reminder that the homes that sell this year are still selling for more than they did a year ago.
For a buyer, this means the price of the homes that sell quickly hasn't softened. What's grown is the number of homes that have been sitting, and those listings carry a different negotiating position than one that went live on Thursday.
Dover Is the Roomiest Market in Its Own County
The pattern sets Dover apart from the towns around it. Here's how the September 2026 single-family figures from the same NH REALTORS® reports compare:
- Dover: 3.2 months of supply, 17 days to sale, $647,500 median sale price
- Strafford County overall: 2.7 months of supply, 24 days to sale, $525,000 median
- Somersworth: 2.3 months of supply, 17 days to sale, $490,000 median
- Rochester: 1.3 months of supply, 12 days to sale, $415,750 median
Dover has the highest price and the deepest supply of the four. A buyer comparing Dover with Rochester is weighing a market where the choices are thinner and homes move faster against one where the median costs about $230,000 more and listings are piling up. In September, Rochester sellers got 100.2% of their original list price. Dover sellers got 99.1%.
None of this makes Dover a buyer's market. In August 2026, the New Hampshire Bulletin reported that statewide supply in July was 2.7 months, below the 4 to 6 months it cited as balanced, and that demand still outweighed supply. In the same piece, a former NH REALTORS® president said multiple buyers still compete for individual homes, even though the pandemic-era frenzy has eased. At 3.2 months, Dover is closer to balance than the state, but it's still short of it.
Downtown Is Adding a Different Kind of Home
The single-family numbers leave out the biggest physical change in Dover this year, which is happening at the river. The City of Dover now describes the Cochecho Waterfront Development as complete, after more than 30 years of planning, with Nebi Park opening in July 2026. The approved plan from developer Cathartes calls for 418 residential units in mixed-use buildings, multifamily buildings, and townhouse clusters.
In January 2026, Seacoastonline reported that Cathartes expected all 220 first-phase units open by late February. The second phase is Building F, with 42 condominiums ranging from one to three bedrooms and from just under 1,000 to 1,600 square feet. Cathartes said it hoped to open that building by March 2027.
More is coming on Central Avenue. Seacoastonline reported this month that the former Harvey's at 376–378 Central Ave. is being redeveloped by owners Matt and Ben Airey. The plan puts 15 apartments above Aubrey's on Central, with completion expected around Christmas 2026 and studios quoted from $1,750. Back in June, the same outlet counted more than 1,760 homes approved or under construction citywide. That count included a 58-unit mixed-use project at 42–44 Third St. The January Seacoastonline roundup also described the Railroad Apartments at 2 Grove St., a building previously planned with 88 below-market-rate units, which developer Bill Goldstein of KAB Realty said should be ready to lease in spring 2026.
Nearly all of this is rental housing or condominiums. None of it appears in the single-family figures above, and the data doesn't show that it's driving the single-family inventory rise. What it does change is the set of choices for someone looking at Dover. A buyer pricing a single-family home near downtown can now also look at a new waterfront condo building on the calendar or a lease near Nebi Park while waiting for the right house.
A Short FAQ
Does a 17-day median mean I have to make an offer the first weekend? For a well-priced home that just listed, often yes. Through September 2026, the homes that sold went in a median of 17 days. That figure says nothing about the homes still on the market, and in September there were more of those than at any point in the prior year's reports.
Is October data available yet? Not as of this post's publication. NH REALTORS® publishes each local update early in the following month, and the September Dover report was current as of October 5, 2026.
Are condo prices following the same pattern? The NH REALTORS® local update for Dover covers single-family homes only, so the figures in this post don't apply to condos or townhouses.
How does Dover compare to Portsmouth or the beach towns? This post sticks to Strafford County comparisons drawn from the same September 2026 reports, so the numbers line up with each other.
Spotting which Dover listings are moving in two weeks and which have been sitting since summer is a house-by-house call, and it determines how hard you can negotiate. If you're weighing a Dover home this fall, The Good Life Real Estate Group can go through the current listings with you, separate the fresh ones from the ones that have been waiting, and help you set an offer to match.
