The $8.3 million house on State Street, and what September looked like for everyone else

Portsmouth just set a record, and it happened in a building most of us have walked past a hundred times.

On September 28, 58 State Street closed for $8.3 million, the highest price ever paid for a home in the city. If you’re picturing a waterfront estate with a lawn running down to the river, picture something more Portsmouth than that: a four-level brick building on a lot smaller than a tenth of an acre, built in 2008 to look like it had always been there. Inside is a penthouse with a private elevator, a second full residence below it, two storefronts at street level, decks looking out at the Piscataqua, and a heated four-car garage, which downtown residents will recognize as the real luxury. All told it’s 8,583 square feet, which works out to roughly $1,065 per square foot.

A few details worth knowing. It was listed in late April at $8.5 million and closed five months later at $200,000 under that number, so even at the very top of the market, the first price wasn’t the final price. The city assesses the property at about $6.56 million, with a 2025 tax bill just under $75,500. And it was listed with the option to convert to condominiums, which tells you something about where buyers at this level see the value: downtown Portsmouth real estate is as much about what a building can become as what it is.

The rest of September was quieter

One record sale doesn’t tell you what’s happening on your street, so here’s the broader picture from the Seacoast Board of Realtors, which tracks thirteen towns from Seabrook up through Portsmouth and New Castle and inland to Exeter, Stratham and Newmarket.

• More to choose from. Single-family inventory across those towns is the highest it has been since June 2020. That’s the first time in over six years buyers have had this much selection.
• Fewer sales. Single-family closings were down 18.1% from both August and from last September, the slowest September in two years.
• Prices holding, not climbing. September’s median single-family price was $799,000, the second-lowest monthly figure this year. For the year so far the median is $882,000, up 3.8% over 2025, and the number of sales is almost identical to last year (two more, to be exact).
• Condos are busier. Condo inventory is also at a multi-year high, but sales held steady at 54 for the month, and the median condo price hit $645,000, the highest of the year. Portsmouth claimed two of the top three condo sales, including a two-bedroom water-view unit at One Harbour Place that went for $2,875,000.
• Rates are still the weight on everything. Mortgage rates stayed above 7% through the month, and that more than anything explains the mismatch between lots of listings and fewer closings.

The board’s president called the single-family market “a bit of a holding pattern,” and that matches what I’m seeing in showings.

What it means if you’re buying or selling

If you’re buying, this is the most breathing room you’ve had in years. You can see more than one house in a weekend, you can ask for an inspection without losing the deal, and well-priced homes are still moving while overpriced ones sit. Sellers aren’t desperate, but they’re negotiating. Both of the top sales this month closed under asking.

If you’re selling, the lesson of 58 State Street applies to a $600,000 cape in Stratham just as much as to a penthouse downtown: the market is rewarding realistic pricing and punishing wishful pricing. With this much inventory, a home that’s priced right in the first two weeks gets the attention; one that’s priced for 2022 becomes the listing everyone watches get reduced.

See you next week, when I’ll share a home that’s for sale right now that I think is worth a look.
