Portland, Maine Housing Market 2026: What Sellers Should Know

The Portland, Maine housing market 2026 story is simple to state: prices are high and have stopped climbing. Zillow's typical Portland value was $559,175 in August 2026, the same as a year earlier (Zillow ZHVI, August 2026). Meanwhile, statewide listings hit a six-year high.

This guide is for owners of houses in Portland, Maine, not Portland, Oregon. Each data source stays in its own lane: the Maine Association of Realtors counts closed county sales, Zillow models values, and Realtor.com tracks listings. Dollar examples are labeled illustrative.

What is the Portland, Maine housing market doing in 2026?

The Portland, Maine housing market is holding its prices but no longer gaining. In Cumberland County, which includes Portland, the median sale price of existing single-family houses was $621,500 for June through August 2026. That is up just 0.89% from $616,000 a year earlier (Maine Association of Realtors, August 2026).

Cumberland County sales rose 3.04% over that rolling quarter, to 1,085 from 1,053. The report covers the whole county, so it is not a Portland city median. The association does not publish a city figure.

Cumberland County is expensive and flat

Cumberland remains the priciest county in the report, but its median rose far less than York County's 7.18%. The association's president noted that as more inventory arrives, "buyers have more opportunities and leverage to negotiate" (Maine Association of Realtors, September 10, 2026).

Portland Maine Home Prices by ZIP Code in Zillow's Data

Zillow's data shows Portland, Maine home prices flat citywide and slipping in one ZIP code. The Zillow Home Value Index (ZHVI) for the city was $559,175 in August 2026, against $559,148 a year earlier (Zillow ZHVI, August 2026).

The ZHVI models the typical value of all houses, including those that did not sell. It is not a sale price and is never averaged with the Realtors' medians.

Each row describes a ZIP code, and some neighborhoods cross ZIP lines. The island ZIP codes rest on small, seasonal samples.

The towns around Portland are still rising

Portland's neighbors are separate municipalities, and most of them gained value while the city stood still. South Portland rose 3.3% to $522,512, and Windham rose 3.4% to $497,149 (Zillow ZHVI, August 2026).

Falmouth reached $897,260 (+2.8%) and Cape Elizabeth $891,700 (+2.9%). Westbrook rose 1.4% to $458,320, and Gorham rose 1.5% to $545,646. Scarborough was the exception, down 0.6% to $690,403.

More Listings, Slower Sales, and 6.95% Mortgage Rates

More houses are for sale in Maine than at any point since late 2019. Maine had 6,258 active listings in August 2026, up 20.0% from a year earlier and the most since December 2019 (Realtor.com, August 2026). The Portland Press Herald noted that sales fell "despite the most for-sale inventory since December 2019" (September 10, 2026).

In the Portland-South Portland metro, active listings rose 11.7% to 1,886. The median listing price was $649,000, and 24.2% of listings had a price cut. The median listing had been on the market 45 days, down from 52 a year earlier (Realtor.com, August 2026).

What Redfin's Portland data shows

Redfin's most recent Portland city file shows a higher sale price on thinner volume. Redfin reported a median sale price of $625,000 in May 2026, up 8.4%, on 67 sales, down 23.9% (Redfin Data Center, May 2026). Redfin uses its own method, so its figures stay apart from the others.

Rates squeeze financed buyers

The 30-year fixed mortgage rate averaged 6.95% for the week of September 17, 2026. A year earlier it was 6.26% (Freddie Mac PMMS, September 2026). At Portland price levels, that gap can push a buyer out of range.

How does rent control affect selling a Portland rental?

Portland rent control limits what the next owner can charge, so it shapes what a buyer will pay for a rental building. The rules are in Portland City Code chapter 6, Articles XII and XIII. They apply only inside the city of Portland.

The 2026 and 2027 caps

The yearly allowable increase equals 70% of the change in the Consumer Price Index (CPI-U) for the Greater Boston Metro Area (City Code §6-232). For 2026, landlords may raise rents by at most 2.2% (Mainebiz, September 4, 2025). The city set 2.6% for 2027 (City of Portland, September 2026).

Other limits in §6-234 matter to a buyer's math:

• No increase within 12 months of the last one.
• A landlord must send a signed notice at least 90 days before an increase, or the notice is void.
• A new tenancy allows an extra 5% of the base rent, but only if the prior tenant left voluntarily.
• Banked increases can be used later, but no single increase may exceed 10% (§6-235).

Base rent generally traces back to the rent charged in June 2020 (§6-233). Buildings with two, three, or four units are exempt only while the owner lives in one of them as a principal residence (§6-231(d)). A buyer who does not move in loses that exemption.

What a landlord must hand a buyer

A few duties come from statute or code, and others are what buyers ask for in practice:

• Security deposits: an accounting of each tenant's deposit and the funds, "no later than at the real estate closing," with written proof (14 M.R.S. §6035).
• Open city orders: a true copy of any housing code order, plus written notice to the city before the transfer (City Code §6-125).
• Lead orders: notice to the buyer of an open lead hazard order, which the new owner must then carry out (22 M.R.S. §1321(4)).
• Rent records, in practice: base rents, increase dates, banked rent, and notices. The code lists no formal package, but buyers will ask.

The new owner must register the rental units within 30 days of purchase (City Code §6-151). Propcash buys houses with tenants in place, so no eviction is needed before you sell. If you are ready to step back from managing units, our options for tired landlords page explains how that can work.

Short-Term Rental Caps: 293 Mainland Units and 40 on Peaks

Portland caps non-owner-occupied short-term rentals, and a buyer cannot inherit the seller's registration. For 2026, mainland non-owner-occupied short-term rentals are limited to 293 units. That is 1.5% of the 19,516 registered long-term rental units counted on September 1, 2025 (Mainebiz, September 4, 2025; City Code §6-153(b)).

Peaks Island is capped at 40 non-owner-occupied short-term rentals (§6-153(c)). The code states that "No registration under this Article shall be transferrable or assignable" (§6-154(d)). New owners registering an existing unit "are considered new applicants," subject to the limits in effect then (§6-151).

If your price assumes short-term rental income, a buyer may not be able to get that income back.

Why Portland's Older Houses Take Longer to Sell

Much of Portland's housing is more than 85 years old, and old systems can slow a financed sale. About 45.8% of the city's housing units were built in 1939 or earlier, and 76.4% before 1980 (U.S. Census Bureau, ACS 2020-2024, table B25034).

Older houses often carry original wiring, oil heat, and lead paint, and a lender may want repairs before closing. Registered rentals must also allow city inspections (City Code §6-151), and any open lead order passes to the buyer.

If your house needs work you do not plan to do, our guide to selling an old Maine house as-is covers disclosure and the repairs buyers ask for.

The Revaluation and the $12.58 Mill Rate

Portland's tax rate for fiscal 2026-27 is $12.58 per $1,000 of assessed value, up 4.9% from $11.98 (Mainebiz, September 4, 2026). The city completed a revaluation in 2025, which updated assessments toward market value.

The first half of the bill is due in October and the second half in March (Mainebiz, September 2026). Confirm exact dates with the city's Treasury office. Illustrative only: a house assessed at $500,000 would owe about $6,290 a year at $12.58.

The city of Portland is the taxing unit; South Portland, Westbrook, and Falmouth set their own rates. At closing, the year's taxes are typically prorated between seller and buyer.

What does it cost to sell a house in Portland, Maine?

A Portland seller typically pays half of Maine's real estate transfer tax, prorated taxes, any payoffs, and any agent commission. The transfer tax is $2.20 for each $500 of value, split "1/2 on the grantor and 1/2 on the grantee" (36 M.R.S. §4641-A). Above $1,000,000, an extra $3.80 per $500 applies to the amount over $1 million.

Illustrative only: on a $560,000 sale, the total transfer tax is $2,464. The seller's half is $1,232.

Income tax and out-of-state sellers

Maine has no separate capital gains rate. A resident's Maine taxable income starts from federal adjusted gross income (36 M.R.S. §5121), and the regular income tax rates apply (36 M.R.S. §5111). Ask a tax professional how any gain applies to you.

If you live outside Maine, the buyer generally must withhold 2.5% of the price on sales of $100,000 or more (36 M.R.S. §5250-A). A seller who certifies Maine residency is exempt. Heirs selling through probate can read our guide to selling an inherited house in Maine, which covers the personal representative (the Maine term for an executor).

A seller's cost checklist

• Half the transfer tax: $2.20 per $500, plus the $3.80 tier above $1 million
• Prorated city taxes at $12.58 per $1,000 of assessed value
• Mortgage payoff and any liens
• Closing attorney or title company fees, which vary by provider
• Agent commission on a listed sale (an illustrative 5% of $560,000 is $28,000)

No Maine statute requires an attorney to run a closing. In practice, a closing attorney or title company prepares the deed, orders payoffs, and records the sale.

Cash Sale vs. Listed Sale in the Portland Maine Housing Market 2026

A cash sale can close in as few as 7 days. By contrast, the median Portland-metro listing had been on the market 45 days in August 2026 (Realtor.com, August 2026). A listed sale also runs through showings, inspection, appraisal, and underwriting. The table lays out the steps with no dates promised on either side.

Where a Propcash offer fits

Propcash is a direct cash homebuyer, founded in 2026 and based in Nashville, that buys houses as a principal. You get one transparent, data-backed cash offer with the reasoning shown. There is no obligation, and the offer stands while you decide.

Sellers pay no fees or commissions to Propcash, and you sell as-is. Title work and payoffs still have to clear, so "as few as 7 days" is not a promise.

How much can a Portland landlord raise rent in 2026?

Does Portland rent control still apply after a building is sold?

Yes. The city's rent control FAQ says transferring ownership does not affect rent control, so base rents and the 12-month clock carry over to the buyer. A two-to-four-unit building is exempt only while the owner lives in one unit, so a buyer who does not move in is covered.
