Portsmouth, NH Housing Market 2026: What Homes Actually Sell For

Portsmouth produces a steady stream of closings but little consensus: sales over the last six months span a range wide enough that the median is a midpoint between different markets, not a going rate. The distribution below matters more than the headline.

The snapshot

• •Closings tracked, last 6 months: 343
• •Median sold price, last 6 months: $695,000
• •Median sold $/sqft, last 6 months: $560
• •Middle half of sales closed between: $525,000 and $1,100,000

What the numbers say

Resideline tracked 343 closed sales in Portsmouth over the last six months, with a median closing price of $695,000. That median is the midpoint of what buyers actually paid, not what sellers hoped to get, which is why it moves differently from the asking prices you see on listing sites. The middle half of those sales closed between $525,000 and $1,100,000. That spread matters more than the headline median: where a specific property sits inside it decides whether the citywide number helps you or misleads you. These are the closings Resideline tracks and may differ from complete county or municipal records. Across the 343 closings with usable living area, the middle half sold between $420 and $698 per square foot.

The Portsmouth angle

Portsmouth's interquartile band runs wider than most markets we track, and that single fact governs how much weight $695,000 can bear. A median drawn from a broad distribution locates the city without describing any particular property inside it, and here the distance from $525,000 to $1,100,000 is substantial. The 343 closings make a solid sample, which is the resource you use against that breadth. Filter to the subject's property type, impose a size window you can defend and keep the radius small enough to mean something, then read the surviving sales rather than the headline. Narrowing the population narrows the range you are pricing within. The halves of the band are unequal, with more dollars above $695,000 than below it. A comp set that leans high therefore moves an estimate further than one that leans low by the same margin, so record where your comps sit before you present a number.

From market read to offer price

A spread this wide means the citywide number cannot price a specific address; the step that matters is the property-level read. The decision still comes down to one property and one number: what it is actually worth and what you should pay. Every Resideline report opens with this same market snapshot for the subject's exact ZIP code, then gives you the property's value, the sold comps behind it, and a market rent estimate. Pricing a specific deal? The free ARV calculator and rental property calculator run the numbers in about a minute.

And we show our work. Every estimate is frozen while the home is for sale and graded against the real closing price after it sells. As of August 2026, the public scoreboard showed 3.26% median error across 12,508+ graded closings. See the live accuracy dashboard for the receipts, or read how the Area Market Snapshot works.
