Best Places to Buy Rental Property in Maine (2026)

Maine recorded 5,762 closings statewide in the last six months at a median sold price of $450,000. That is a small market by national standards, and it shapes everything about investing here: only a handful of Maine cities generate enough transaction volume for an investor to buy and sell without waiting on a very small pool of counterparties. The 15 markets below are the cheapest Maine cities that cleared 100 closings in six months, ranked cheapest first. Worth noting up front: only five of them close below the state median. Maine's remaining liquid markets, Gorham at $640,000, York at $720,500, and Scarborough at $741,500, all price higher still. One honesty note before the list. There are no rent figures, rent-to-price ratios, cap rates, or cash-on-cash returns in this article. We do not have verified rent data at the city level, and Maine's mix of year-round, seasonal, and coastal housing makes a city-average rent especially misleading. Verify rent for the specific property, then run the numbers yourself with the rental property calculator and the deal analyzer. This ranking covers entry price and transaction volume, which is what the data can actually support.

Maine's most affordable markets with real transaction volume

Look at the jump between Sanford at $376,000 and Biddeford at $499,900. There is a $123,900 cliff in the middle of this list with nothing in between. Maine effectively has two investable price tiers and very little connecting them.

1. Augusta, $289,950 median, 109 closings

The cheapest liquid market in Maine, 36% below the state median, with 109 closings, roughly 18 a month. As the state capital it has a stable government employment base, which supports year-round tenant demand rather than seasonal.

2. Bangor, $300,000 median, 246 closings

The best entry-price-to-liquidity combination in the state, full stop. A $300,000 median, 33% below the state figure, with 246 closings, about 41 a month, which is the second highest count on this list. Bangor is the commercial and medical hub for northern and eastern Maine, so its demand base is regional rather than local. If you want cheap Maine with a functioning market attached, this is the clearest answer in the data.

3. Lewiston, $345,000 median, 142 closings

$345,000 across 142 closings, about 24 a month, 23% below the state median. Lewiston is one of Maine's larger cities with a dense stock of older multi-unit housing, which means condition and systems risk deserve close attention and can vary enormously between two buildings on the same block.

4. Auburn, $356,000 median, 101 closings

Directly across the river from Lewiston at $356,000 on 101 closings, roughly 17 a month, among the lowest counts on this list. The two cities function as one trade area, so the practical liquidity is better than Auburn's own count suggests, but the local market itself is small.

5. Sanford, $376,000 median, 128 closings

$376,000 on 128 closings, about 21 a month, 16% below the state median. Sanford is the last market on this list under $400,000 and the cheapest option in York County, which puts it within reach of the southern Maine employment base without southern Maine coastal pricing. It also appears among the state's dozen busiest markets.

6. Biddeford, $499,900 median, 133 closings

The first entry above the state median, at $499,900 on 133 closings, about 22 a month. Biddeford has been the most visibly changing of Maine's smaller cities, with substantial mill redevelopment, and it prices accordingly. Entry cost is $123,900 above Sanford for a location closer to the coast and to Portland.

7. Old Orchard Beach, $500,000 median, 100 closings

$500,000 with exactly 100 closings, about 17 a month, the thinnest volume on this list. A seasonal beach economy, which is the central underwriting question here: year-round tenant demand, seasonal demand, and the associated vacancy pattern are entirely property specific and must be verified rather than assumed.

8. Westbrook, $501,000 median, 160 closings

$501,000 across 160 closings, about 27 a month, immediately adjacent to Portland. Better liquidity than most of this middle tier and a location tied directly to the state's largest employment center. It is one of Maine's 12 busiest markets.

9. Windham, $502,500 median, 117 closings

$502,500 on 117 closings, about 20 a month, inland from Portland near Sebago Lake. Modest volume, priced with the rest of the greater Portland ring, with some lake-area seasonal influence in the housing mix.

10. Brunswick, $507,000 median, 144 closings

144 closings, roughly 24 a month, at $507,000. Brunswick has a college and a healthcare presence that support steadier year-round demand than the seasonal markets on this list, and reasonable volume for a town its size.

11. South Portland, $525,000 median, 195 closings

The third deepest market on this list at 195 closings, about 33 a month, priced at $525,000. Directly across the harbor from Portland with its own employment and retail base. Strong liquidity for Maine, at a $75,000 discount to the Portland median.

12. Saco, $525,000 median, 120 closings

The same $525,000 median as South Portland, on 120 closings, about 20 a month. That is roughly 60% of South Portland's volume at an identical price. When two markets price the same, transaction depth decides it.

13. Wells, $573,250 median, 161 closings

$573,250 across 161 closings, about 27 a month, 27% above the state median. Southern coastal York County, where the seasonal and second home component of demand is significant. Good volume for a coastal town, but the buyer pool at this price point is different from the workforce housing markets at the top of this list.

14. Kennebunk, $574,900 median, 107 closings

$574,900 on 107 closings, about 18 a month. Coastal, premium positioning, thin volume. The entry cost is roughly double Augusta's with comparable transaction depth, which is a straightforward statement of what coastal southern Maine costs.

15. Portland, $600,000 median, 338 closings

The most liquid market in the state by a clear margin, at 338 closings, roughly 56 a month, and the most expensive on this list at $600,000, or 33% above the state median. Portland is where Maine's comparable sales are most plentiful and valuations best supported, and where exit risk is lowest. You pay for all of that in the entry price.

The part the rankings cannot decide

Maine's total closing volume is small enough that any city-level median rests on a limited number of sales, and property level dispersion inside these markets is wide. Seasonal versus year-round use, heating systems, water and septic, and structural condition move Maine values in ways a median cannot capture. So run an actual valuation and inspect the comparable sales behind it. Ours are visible and adjustable, which is especially valuable in thin markets where you need to know whether an estimate rests on three genuinely similar sales or on three loosely related ones. Condition is estimated from listing photos, which matters given Maine's older housing stock. Our estimates are frozen at listing and then graded against the real closing price, and that scoring is published on our accuracy dashboard. Then build the deal with your own assumptions. The ARV calculator covers renovation exits, and the market pages provide local data rather than a statewide median that fits almost no one. It is all on the free tools page, no signup, and live valuations cover 31 states including Maine.
