South Portland, ME Housing Market 2026: What Homes Actually Sell For

If you invest in or around South Portland, the number that matters is what homes actually close for, not what sellers are asking. Here is what South Portland sale prices look like right now, built from the closings Resideline tracked over the last six months, as of October 2026.

The snapshot

• •Closings tracked, last 6 months: 203
• •Median sold price, last 6 months: $525,000
• •Median sold $/sqft, last 6 months: $358
• •Middle half of sales closed between: $425,000 and $707,000

One thing to know about Maine data: Maine is a non-disclosure state, which means sale prices are not public record. The sold figures above come from closings Resideline tracked directly.

What the numbers say

Resideline tracked 203 closed sales in South Portland over the last six months, with a median closing price of $525,000. 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 $425,000 and $707,000. 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 203 closings with usable living area, the middle half sold between $307 and $427 per square foot.

Where South Portland sale prices land

Medians hide the shape of a market. The distribution above covers the closed sales Resideline tracked in South Portland over the last six months that carry a usable sale date, trimmed to the 5th through 95th percentile, with the middle half of sales closing between $425,000 and $707,000. Among the 8 Maine markets with a published band, South Portland's middle-half spread ($425,000 to $707,000) ranks 3rd from the narrowest. Where your target property sits inside that spread matters more than the citywide median. Measured as the ratio of the upper to the lower quartile, its middle-half spread ranks in the 48th percentile of the 2,291 US markets in Resideline's national Market Watch set, on data as of November 3, 2026.

How long a sale takes here

• •Listed to under contract: a median of 13 days, across 131 South Portland closings Resideline tracked in the last six months
• •Contract to closing: a median of 28 days, across 121 South Portland closings Resideline tracked in the last six months

Both are measured from the closings themselves, not from listing inventory. Each sale is timed using its own listing and contract dates. That is why these counts are smaller than the 203 closings above: a sale is counted here only when we hold both of its dates.

The South Portland angle

Thin sample, ordinary spread: that combination sets the ground rules for South Portland. The band from $425,000 to $707,000 is about as wide as our markets generally run, so the shape of the distribution is not unusual, but 203 closings is fewer than most markets we track carry. Rather than filtering hard and ending up with a set too small to read, assemble the closest matches available, then check them against the band before drawing a conclusion. The upper half, from $525,000 to $707,000, is the wider side of the band. A comp set that under matches on size or finish will therefore sit low relative to the property you are pricing. Treat $525,000 as an orientation figure, hold in mind that it marks the middle of the record and not a level any property must reach, and remember that $425,000 to $707,000 accounts for half of all closings, not all of them.

From market read to offer price

A market read is the backdrop. 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, rehab cost estimator, BRRRR 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, so it cannot be revised once the sale price is known. Grading it is a different matter in Maine: because sale prices are not public record here, a confirmed closing price reaches us for only a small share of Maine homes, and most Maine estimates stay frozen and ungraded. The accuracy scoreboard is therefore a national record rather than a Maine one. See the live accuracy dashboard for the receipts, or read how the Area Market Snapshot works.

Run any South Portland address through Resideline and you will see the local market and the property's value together, in one report.
