Maine is a state of small markets with large personalities: Portland's working waterfront and restaurant scene, the healthcare-and-college economies of the inland cities, and two coastal destinations, Old Orchard Beach and Mount Desert Island, where a short summer season does most of the earning. Home prices run from about $287,000 in Augusta to about $663,000 in Bar Harbor (Zillow, 2026), and the markets in between reward very different strategies, which is exactly why investors comparing them typically start with “rent-to-price ratios.” Investors buying here typically finance with Maine DSCR loans, which are qualified primarily based on the property rather than the borrower's personal income.
This breakdown uses market data collected as of October 2026, the most current snapshot available heading into next year's buying season. If you're evaluating a purchase in the final months of 2026, keep in mind that your first full year of rental income, appreciation, or short-term rental revenue lands in 2027 regardless of when you close. A deal you underwrite today is already a 2027 investing decision, just one made with the freshest data available right now.
Maine has no statewide short-term rental license and charges a 9% lodging tax on stays of fewer than 28 consecutive days, so the real rules are written town by town: Portland runs a registration program with tiered permits, and Bar Harbor limits non-owner-occupied rentals under a cap that voters approved in 2021. For a full rundown, see BNBCalc's guide to Maine STR rules.
One pattern shows up in Redfin's “Compete Scores”: Portland scores 75 out of 100 and Augusta 74 (both “very competitive”), with Old Orchard Beach at 64 and Bangor at 60, which suggests that falling median sale prices in Portland and Bangor do not mean buyers have the upper hand.
Below, we break down six Maine markets worth watching, using current data from Zillow, Redfin, BiggerPockets, and AirDNA.
Note: Home price appreciation and rent-growth figures below come from Zillow's Home Value Index (ZHVI), Redfin's median sale price data, and BiggerPockets' Market Finder, which use different methodologies and can vary from one another. BiggerPockets figures describe each metro, while Zillow and Redfin figures describe the city itself, and BiggerPockets' Maine pages show home prices well below, and appreciation well above, what Zillow and Redfin report, which suggests they reflect an earlier period, so treat them as directional. Augusta and Old Orchard Beach have no BiggerPockets figures here and rely on Zillow and Redfin, while Lewiston and Bar Harbor rely on Zillow because current Redfin city data wasn't available for them.
Boston-bound buyers and big-city prices
Portland is Maine's largest city and the rare market where the median sale price can fall 5.9% – and buyers still lose the “bidding war” – because its tourism and healthcare economy keeps demand running well ahead of supply.
Maine Medical Center and a college-and-tourism economy give Portland the deepest tenant pool in the state, and Redfin's search data, which tracks home searches rather than actual moves, shows Boston buyers looking at Portland far more than any other metro, with a net inflow of 925 against 104 for the next-largest, Washington. However, the entry price is the “catch”: at roughly 0.43% a month, the rent does not come close to the 1% many investors use as a rule of thumb, so the case rests on appreciation and on the STR side. Portland requires short-term rentals to register with the city under a “tiered permit system,” according to Awning's Maine guide, so confirm the tier available for the specific address.
Portland posts an AirDNA market score of 57/100, with Rental Demand (79) and Revenue Growth (74) leading, Investability (70) and Regulation (61) in the middle, and Seasonality (47) the weak spot. Annual revenue per listing averages $56,046 (up 4.0% year-over-year), with an average daily rate of $333.54 (up 4.5%) and occupancy of 61% (down 0.7%). Total active listings sit at 1,373, down 1.6% over the past year, so supply is easing as income edges up. Downtown Portland leads the submarkets with a score of 68 and $55K in revenue per listing.

Investor Takeaway: Portland offers the deepest demand and the best rent growth in the state at the price of the thinnest rent-to-price ratio. Investors should generally underwrite the long-term rent on its own merits and treat the STR income as a bonus that depends on the registration tier.
Best-in-class ratios and a college-town base
Bangor is the commercial hub of eastern and northern Maine, and it pairs the highest rent-to-price ratio among the core markets with a healthcare-and-university economy – one that does not depend on tourists.
Eastern Maine Medical Center and the University of Maine give Bangor a healthcare-and-education base that usually holds up better than a one-industry town, and the 0.74% population growth is a positive in a state of small markets. However, BiggerPockets' $214,100 median home price and 10.47% appreciation sit far from Zillow's $295,453 and 1.2% and Redfin's 2.4% decline, so the honest read is a stable market with modest price movement, not a “double-digit boom.”
Bangor's AirDNA submarket posts a score of 57/100, with Investability (77) leading, Rental Demand (67) and Revenue Growth (63) in the middle, and Regulation (59) the softest subscore. Annual revenue per listing averages $31,329 (up 0.9% year-over-year), with an average daily rate of $178.42 (up 2.2%) and occupancy of 59% (down 3.3%). Total active listings sit at 375, down 3.9% over the past year, and the top listings are waterfront retreats, which is where the premium sits.

Investor Takeaway: Bangor is the best cash flow ratio among the core markets in the article, with a stable, non-tourist demand base. Investors should generally lean on the long-term rent and treat the STR side as a waterfront-only play.
State-capital steadiness at the state's lowest price
Augusta is Maine's capital, and it carries the lowest typical home value in this article alongside a very competitive buyer market, a pairing that tends to reward investors who buy carefully rather than quickly.
State government and hospital employers give Augusta a steadier job base than most markets of its size, and its 0.53% rent-to-price ratio on Zillow is second only to Bangor on this list. However, a Compete Score of 74 alongside 37.8% of homes with “price drops” points to a market where well-priced homes move quickly and overpriced ones sit, so the discipline is in the entry price. Redfin shows no migration data for Augusta, and BiggerPockets figures aren't included here.
Augusta's AirDNA submarket posts a score of 53/100, with Investability (73) leading, Rental Demand (66) and Seasonality (64) in the middle, and Regulation (53) the softest subscore. Annual revenue per listing averages $31,667 (down 1.9% year-over-year), with an average daily rate of $187.04 (up 7.2%) and occupancy of 59% (down 10.2%). Total active listings sit at 194, up 3.7% over the past year, so rates are rising on falling occupancy, a pattern that rarely lasts.

Investor Takeaway: Augusta offers the lowest entry price and a respectable rent-to-price ratio in a market that rewards disciplined buyers. Investors should generally buy for the long-term rent and treat the STR side with caution while occupancy is falling.

College-and-hospital demand with a flood-map footnote
Lewiston is the larger half of the Lewiston-Auburn metro on the Androscoggin River, and its hospital, college and manufacturing base gives it steady rental demand along with one of the starker flood ratings in this article.
Central Maine Medical Center and Bates College give Lewiston a diversified rental audience, i.e. hospital staff and students, and the 0.98% population growth is the fastest in the core group. However, Redfin's First Street data rates the city's flood risk as “extreme,” with 16% of properties at risk of severe flooding over the next 30 years, so insurance quotes belong in the underwriting before the offer.
Lewiston's AirDNA submarket posts a score of 50/100, with Seasonality (79) leading, Rental Demand (62) and Regulation (60) in the middle, and Investability (59) and Revenue Growth (51) softer. Annual revenue per listing averages $24,788 (up 5.0% year-over-year), with an average daily rate of $135.63 (up 10.9%) and occupancy of 58% (down 2.8%). Total active listings sit at just 89, up 1.1%, so this is a thin market where a lakefront listing such as Taylor Pond (81% occupancy, $68K) is the exception.

Investor Takeaway: Lewiston pairs steady rent growth and population gains with a thin STR market and an extreme flood rating. Investors should generally underwrite it as a long-term rental and price the flood insurance before they price the deal.
Beach-town revenue, borrowed from Boston
Old Orchard Beach is a southern Maine beach town whose short-term rental income depends on a few warm months and on buyers from farther south, and it carries a flood rating that matches its address!
The town's beach and summer crowds make it one of southern Maine's best-known visitor destinations, and Redfin's search data, which tracks home searches rather than actual moves, shows Boston buyers looking at the area more than any other metro, with a net inflow of 925. The physical risks are real, however: Redfin's First Street data rates the flood risk as “major,” with 23% of properties at risk of severe flooding over the next 30 years and the risk rising faster than the national average, and the wind risk as major as well, so insurance deserves a line in every underwriting model.
Old Orchard Beach's AirDNA submarket posts a score of 48/100, with Rental Demand (68) and Revenue Growth (65) leading, Investability (63) and Regulation (60) in the middle, and Seasonality (47) the weak spot, i.e. income is concentrated in summer. Annual revenue per listing averages $48,112 (up 2.1% year-over-year), with an average daily rate of $367.61 (up 2.4%) and occupancy of 62% (down 0.2%). Total active listings sit at 827, down 1.8% over the past year, and the top beachfront listings earn $276K to $312K a year at roughly 56% occupancy.
Financing note: Old Orchard Beach deals often qualify on TTM actuals or STR revenue projections given the seasonal revenue base, and Harpoon Capital offers industry leading DSCR Loans for properties throughout the market area. Check out our full DSCR Loans Program here, or if you want a quote on what terms look like today, fill out this two-minute form!
Sources: Zillow Home Value Index↗ · Redfin Housing Market↗ · AirDNA↗
Investor Takeaway: Old Orchard Beach offers beach-town revenue and strong buyer competition with a major flood rating and a short season. Investors should underwrite the off-season honestly and get insurance quotes early.
Acadia-gateway revenue under owner-occupancy rules
Bar Harbor is the gateway to Acadia National Park on Mount Desert Island, a market where the tourist season is the business plan – and it posts the best short-term rental numbers in this article!
Acadia National Park and a cruise-and-hiking season that fills the town from summer into fall give Bar Harbor some of the strongest visitor demand in New England, and AirDNA's Rental Demand score of 93 is the highest subscore in the article. The rules are the gate: BNBCalc reports that voters approved restrictions in 2021 that separate “owner-occupied” from “non-owner-occupied” rentals and cap the latter, and that owners need an annual “registration card” from the town, so confirm what is available for the specific property before you buy. Redfin's current city data wasn't available for Bar Harbor, and BiggerPockets figures aren't included here.
Bar Harbor's AirDNA submarket posts a score of 74/100, with Rental Demand (93) leading, Investability (78) and Revenue Growth (76) in good shape, Regulation (62) in the middle, and Seasonality (43) the weak spot, i.e. income is heavily concentrated in the warm months. Annual revenue per listing averages $71,183 (up 11.3% year-over-year), with an average daily rate of $442.71 (up 12.0%) and occupancy of 74% (up 1.1%). Total active listings sit at 632, down 4.4% over the past year, so revenue and rates are climbing on a shrinking supply base. A downtown house listed at 100% occupancy and $306K in revenue shows where the ceiling sits.
Financing note: Bar Harbor deals often qualify on TTM actuals or STR revenue projections given the seasonal revenue base, and Harpoon Capital offers industry leading DSCR Loans for properties throughout the market area.

Sources: Zillow Home Value Index↗ · BNBCalc Maine STR Guide↗ · AirDNA↗
Investor Takeaway: Bar Harbor offers the highest STR revenue, occupancy and rate growth in the article behind the tightest permitting and the highest entry price. Investors should confirm the owner-occupancy status first, and underwrite the shoulder seasons rather than the peak summer weeks.

A few patterns stand out. Bar Harbor is the only market where revenue and occupancy are both rising ($71,183, up 11.3%), and it does so on a supply base that fell 4.4%, which is what a “capped market” looks like in the data. Supply is shrinking in four of the six markets, with Augusta the exception, where rates rose 7.2% while occupancy fell 10.2%, and the inland markets earn $24,788 to $31,667 per listing against $48,112 to $71,183 on the coast. Seasonality scores of 43 to 47 in the coastal markets are the reminder that the coastal income is earned in a few months.
Maine's real estate landscape offers a strategy for nearly every type of investor:
Market-level data is a starting point, not a substitute for underwriting the specific property, neighborhood, and rental strategy in front of you. Maine leaves short-term rental regulation to its towns, and Portland and Bar Harbor both restrict who can operate, so confirm what's legal at your specific address before you close, and price flood and wind insurance into every coastal and riverside deal.
If you are ready to invest in one of these markets, start with our Maine DSCR loans page.

Maine charges a 9% lodging tax on short-term rentals of fewer than 28 consecutive days, according to Awning's 2026 guide, and some towns add their own registration or licensing requirements. Rates and rules change, so confirm current figures with the state and your town before you close.
No. Out-of-state and first-time investors can buy investment property in Maine without any license. A DSCR loan qualifies you primarily based on the property itself rather than your personal income or professional credentials, which is part of why it's such a common financing tool for out-of-state buyers.
A DSCR (Debt Service Coverage Ratio) loan qualifies a property primarily based on the property (its value, value and location) relative to its mortgage payment, rather than the borrower's personal income or tax returns. If the property's projected or actual rent covers the mortgage payment (a DSCR of 1.00x or higher), it's generally easier to qualify, and Harpoon Capital also offers options for deals below 1.00x.
Possibly, but with limits. BNBCalc reports that Bar Harbor voters approved restrictions in 2021 that separate owner-occupied from non-owner-occupied rentals and cap the non-owner-occupied ones, and that owners need an annual registration card from the town. Confirm what is available for the specific property before you buy with an STR strategy in mind.
Harpoon Capital's DSCR loan program allows as little as 15% down on qualifying purchases, up to 85% LTV, with cash-out refinances available up to 80% LTV. Exact terms depend on the property, credit profile, and DSCR ratio. Fill out our DSCR Loan Application to see specific numbers for your deal.
