The snapshot
- •Closings tracked, last 6 months: 202
- •Median sold price, last 6 months: $531,500

- •Middle half of sales closed between: $435,000 and $707,000
What the numbers say
Resideline tracked 202 closed sales in South Portland over the last six months, with a median closing price of $531,500. 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 $435,000 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 202 closings with usable living area, the middle half sold between $307 and $433 per square foot.

The South Portland angle
Thin sample, ordinary spread: that combination sets the ground rules for South Portland. The band from $435,000 to $707,000 is about as wide as our markets generally run, so the shape of the distribution is not unusual, but 202 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 $531,500 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 $531,500 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 $435,000 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 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.
