Maine has emerged as a top physician lifestyle and investment market, driven by remote-worker in-migration from Boston, New York, and beyond, with home values up ~4.8% YoY. Portland is one of the most dynamic small cities in New England — a nationally recognized culinary and culture scene creates year-round STR demand beyond summer tourism. The coastal STR corridor (Bar Harbor, Kennebunkport, Ogunquit) commands premium ADRs among the highest in New England. Two discipline items: coastal seasonality is steep — strong June–September, significantly lower November–March — and winters add $4,000–8,000 per year in maintenance versus southern comparables. Property tax at 1.36% belongs in every pro forma. And treat Maine like residency: learning a market takes reps, so pace yourself and start with one door.

Long-term rental markets

Augusta is the efficiency leader — homes near $195,000 renting around $1,100/mo (14.8× GRM) on state-government stability. Lewiston ($188,000, 14.9×) is anchored by Central Maine Medical, and Bangor ($248,000, 16.5×) is the regional hospital hub built around Northern Light Health. South Portland ($445,000, 21.2×) is the accessible route into the Portland metro.

Short-term rental markets

Portland offers the most balanced year-round STR demand of any Maine market — $495,000 entry, ~$235/night at 62% occupancy. Boothbay Harbor ($495,000, ~$325/night) trades on lobster-and-maritime tourism; Bar Harbor is the state's top STR destination at the Acadia gateway — $635,000 entry, ~$395/night at 70% occupancy in peak season; and Ogunquit ($695,000, ~$385/night at 72%) adds a strong shoulder season. When summer guests weigh coastal listings side by side, a themed cottage or standout amenity frequently tips the choice. All four carry moderate STR regulation — verify local rules, and model the winter trough honestly.

Up-and-coming markets

Biddeford ($298,000) is the revitalized mill city with UNE and an emerging arts scene; Brunswick ($368,000) draws on Bowdoin College and Brunswick Naval Air Station demand; Ellsworth ($325,000) is the fast-growing Acadia gateway hub; and Scarborough ($448,000) offers strong family rental demand south of Portland.

The bottom line for physician investors

Maine pairs lifestyle-grade coastal STR economics with steady inland LTR anchors in Augusta, Lewiston, and Bangor. Underwrite the seasonality curve and the winter maintenance budget first — the premium summer ADRs reward the investors who model November through March honestly. Seasonal markets are also unforgiving of a weak local team, and building the right one will make or break your results.
