What Is the Most Expensive Town to Live in Southern Maine?

Southern Maine holds the state's priciest housing. Cumberland County posted a June 2026 median sale price of $620,000 and York County $583,725, against a statewide median of $436,000.

Inside those counties, a handful of towns run well above the county median. Here is what they are and what is actually driving the numbers.

The high-price towns in York County

Kennebunkport reaches the top of York County on a small transaction base. Frontage on the Kennebunk River and the Atlantic, a heavy second-home ownership share, and tight zoning combine to produce very high per-square-foot pricing. Goose Rocks Beach and Cape Porpoise carry their own premiums.

Ogunquit shows some of the highest per-square-foot figures in Maine on very limited inventory, driven by beachfront, the walkability of the village, and short-term rental demand.

York Harbor prices above the rest of the town, with substantial shorefront properties and limited turnover.

Wells varies more than any of these. Beachfront at Drakes Island and Moody prices at the top of the county, while inland Wells along Route 109 sits well below it.

Kennebunk's Beach Avenue corridor prices with the coastal top tier, while West Kennebunk sits considerably lower.

The high-price towns in Cumberland County

Cape Elizabeth consistently prices at or near the top of the region. The town covers a peninsula south of Portland with roughly ten miles of coastline, and a significant share of its land is conservation or park. Limited developable land plus limited turnover keeps inventory thin.

Falmouth sits directly north of Portland along Casco Bay. Large lot zoning across much of the town, waterfront on the eastern side, and a short drive to Portland keep pricing high.

Yarmouth is smaller, built around a village center on the Royal River, with island and bay frontage. Inventory is limited by size alone.

The Casco Bay islands show high medians on very few annual transactions, which makes their statistics volatile year to year.

What actually drives the pricing

Four factors do most of the work.

Water. Direct frontage, deeded access, or a view carries a measurable premium across Southern Maine. Ocean frontage prices differently than tidal river frontage, which prices differently than a pond. Access without frontage still adds value.

Land supply. Cape Elizabeth, Falmouth, Yarmouth, and Kennebunkport all carry large minimum lot sizes across substantial portions of their zoning maps. Less subdividable land means fewer new houses, which concentrates competition on existing stock.

Proximity to a city. Drive time to Portland or Portsmouth is a straightforward price input. Falmouth and Cape Elizabeth sit ten to fifteen minutes from Portland. Kittery and Eliot sit minutes from Portsmouth. That is worth real money.

Second-home demand. In Kennebunkport, Ogunquit, and parts of Cape Elizabeth, a meaningful share of buyers are not competing on local wages. That decouples price from local income and pushes medians higher than employment data alone would predict.

What a high median does not tell you

A high median does not mean every house in town is expensive. Cape Elizabeth has condominiums and smaller homes well below the town median. Wells spans an enormous range. Kennebunk, next to Kennebunkport, prices considerably lower with much of the same coastal access.

It also does not tell you your carrying cost. A town with a low mill rate and high assessed values can produce a larger tax bill than a town with a high mill rate and low values. Always calculate the actual number rather than comparing mill rates.

If you are shopping the high end

Three practical notes.

Inventory is thin, so timing matters more than in broader markets. In towns with twenty or thirty single-family sales a year, the right house may appear twice a year. Being ready to move matters more than waiting for a better market.

Get the water rights in writing. Deeded access, shared docks, right of way language, and shoreland zoning restrictions vary enormously and are frequently misdescribed in marketing. Read the deed.

Understand shoreland zoning before you plan changes. Maine's Mandatory Shoreland Zoning Act restricts what you can build, clear, or expand within 250 feet of most water bodies. Confirm what is permissible before closing, not after.
