Washington County

Washington County, Maine carries a median home price of $200,966 with year-over-year appreciation of just 0.42%, which tells you most of the story immediately. This is not a market you underwrite for price growth. The affordability index of 87 is one of the stronger readings you'll find in the Northeast, reflecting genuine entry-point accessibility relative to income, and the county ranks 2nd out of 16 Maine counties overall. What the data does not give you here are completed cap rate and cash-on-cash figures, the investable estimates show zeroes across rent, cash flow, and return calculations, which means any underwrite you build will need to be driven by your own rental comps pulled from the ground. That gap itself is a signal worth taking seriously: thinner data coverage often tracks with thinner liquidity.

The scores make the positioning explicit. Cash flow scores a flat zero, appreciation scores 54 out of 100, and stability sits at 50. That spread tells you this county is neither a reliable cash-flow engine nor a high-conviction appreciation play. What it offers is a low entry price, $200,966 at the median, and an affordability score of 87 that suggests the buyer pool for your eventual exit isn't priced out of the market. For a value-add operator willing to buy below median in a low-price-point market, force equity through renovation, and hold for five-plus years, the math can work on the front end. A pure cash-flow buyer relying on the numbers as presented has nothing to build from yet, and an appreciation buyer expecting meaningful price acceleration from a 0.42% trailing YoY figure will need a thesis beyond what this data supports.

On carry costs, the combined monthly property tax and insurance figure comes to $266, derived from Maine's state-average effective property tax rate of 1.36% and an insurance rate of 0.23% applied to the $200,966 purchase price. The 1.36% rate is flagged as normal, which it is relative to national benchmarks, though you should treat it as a floor estimate rather than a ceiling. The note accompanying this data is explicit: it represents a state-average effective rate from Tax Foundation 2024, and actual county or township rates in Washington County may differ. At $2,733 in annual taxes and $462 in annual insurance on a ~$201,000 asset, these are manageable line items, but on a low-rent rural property where gross revenue is limited, $266 per month in fixed carry is a meaningful slice of any margin. Model it conservatively and verify the actual millage rate with the county assessor before closing.

The neighbor comparison is where Washington County's positioning sharpens. Aroostook County to the north carries a lower median at $158,894 and a rent-to-price ratio of 0.0717, the highest of any neighbor with available rent data, which translates to meaningfully better gross yield potential on paper. Penobscot County, home to Bangor, sits at a $270,057 median with a rent-to-price ratio of 0.0670 and the same overall score of 63 as Washington. Androscoggin County reaches a $319,791 median with a rent-to-price ratio of 0.0582, the weakest yield profile among the neighbors with rent data. Washington County's position, no rent-to-price ratio calculable from the provided data, is the real limitation here. If your goal is the highest gross yield in Maine, Aroostook is the number to beat. If you want Bangor-market infrastructure, population base, and liquidity, Penobscot at the same overall score is a more legible bet. Washington makes sense over its neighbors specifically when you are targeting a low absolute purchase price with Maine residency demand, buying well below the median, or pursuing a niche strategy tied to the county's geography, but the data does not hand you a yield advantage to justify it on fundamentals alone.

The primary risk in Washington County is concentration and scale. A population of 31,096 spread across the largest county by area in Maine east of the Mississippi means thin tenant pools, longer vacancy exposure, and fewer comparable sales to support your exit valuation. Stability scoring at 50 out of 100 confirms this is not a market with deep demand cushions. No vacancy or demographic trend data is provided here, so quantifying that risk further would require primary research, but the population figure alone should inform how much of your portfolio you concentrate in a single Washington County asset versus using it as a selective, opportunistic allocation within a broader Maine strategy.
