Why Investors Consider Union

Investors are drawn to Union for its favorable revenue-to-price dynamics, limited existing supply, and strong seasonal demand driven by Maine's midcoast appeal.

Expert Market Assessment

"Union earns a Standout Opportunity designation thanks to its above-average revenue-to-price ratio and occupancy stability, supported by a favorable supply/demand balance. The market's seasonality is pronounced — August revenue of $11,667 dwarfs the January figure of $1,036, so investors need to plan cash flow around a roughly five-month high season from June through October. With average home values at $558,690 and annual revenue averaging $48,683, the gross yield looks attractive for a coastal Maine town. The small listing pool and rapid year-over-year growth signal an emerging market where early movers can establish strong positioning."

Key Airbnb Metrics & Trends in Union

Average revenue by month in Union

Union's revenue profile is sharply seasonal, with August ($11,667) and July ($10,231) delivering roughly ten times the income of January ($1,036). The five-month stretch from June through October accounts for the vast majority of annual earnings, making cash-flow planning essential for the quieter winter months.

Active Airbnb listings by property size in Union

The entire reportable supply in Union consists of 1-bedroom properties, with 10 active listings in that category. This concentration suggests that larger properties are either absent or too few to report, potentially signaling an opportunity for investors willing to offer multi-bedroom accommodations.

Average daily rate (ADR) by property size in Union

One-bedroom listings in Union command an average daily rate of $177, which sits below the market-wide ADR of $208. The gap hints that larger or unique properties in the market (not broken out separately) may be pulling the overall average higher, offering a potential premium for differentiated listings.

Average RevPAN by property size in Union

One-bedroom properties deliver a RevPAN of $79, which actually exceeds the market-wide average of $67. This suggests that smaller units are converting their available nights into revenue more efficiently than the broader market, likely benefiting from stronger occupancy.

Average occupancy rates by property size in Union

One-bedroom listings achieve a 45% occupancy rate — well above the market-wide average of 32%. This higher fill rate translates into more predictable cash flow and indicates consistent demand for smaller, well-priced accommodations in Union.

Average annual revenue by property size in Union

At $64,833 in average annual revenue, 1-bedroom listings outperform the overall market average of $48,683 by a significant margin. Against average home values of $558,690, this revenue figure provides a starting point for investors evaluating gross yield potential.

Understanding Union's ROI Score: 83/100

Rabbu's ROI Score is a proprietary metric that evaluates short-term rental investment potential based on multiple factors.

How the ROI Score is Calculated

What This Means for Investors

Union's ROI score of 83 out of 100 places it in the Standout Opportunity band, driven primarily by an above-average revenue-to-price ratio and strong occupancy stability. The supply/demand balance also scores above average, reflecting a market where 17 listings face healthy demand without overcrowding. Investors should pair these favorable metrics with thorough local regulatory research and factor in the pronounced seasonality when modeling returns.

Short-Term Rental Regulations in Union

Understanding local STR regulations is essential before investing in Union. Here's the current regulatory landscape:

Permit Requirements

Short-term rental operators in Union, Maine may be required to register their property or obtain a local permit before listing. Investors should verify current requirements with the Town of Union and the State of Maine, as regulations can evolve.

Key Restrictions

Common STR restrictions in Maine communities can include occupancy limits, minimum stay requirements, noise ordinances, and parking provisions. HOA rules may also apply depending on the property, and some municipalities impose caps on the number of permits issued — checking with local authorities before purchasing is strongly recommended.

Tax Obligations

Maine imposes a lodging tax on short-term rentals, and operators should also be aware of potential local assessment obligations. Many booking platforms collect and remit state taxes automatically, but hosts should confirm their specific obligations with the Maine Revenue Service.

Regulations subject to change. Always verify with local authorities before purchasing. A Rabbu partner agent specializing in Union can provide current regulatory guidance.

Future Outlook & Long-Term Forecast

"Over the next 12–18 months, Union's STR market is expected to maintain its strong summer-driven revenue cycle, with August and July likely continuing as the top-earning months. Given the 113% year-over-year growth in active listings, ADR may face mild pressure as supply expands, though the market's small base of 17 listings means even modest demand increases could absorb new inventory. Occupancy rates during peak months should remain robust, while winter months will likely stay soft — investors should budget for revenues around $1,000–$1,500 per month from November through March. Overall, we estimate steady performance with potential ADR adjustments in the 1–3% range as the market matures."

How is Airbnb revenue calculated in Union?

The annual and monthly revenue figures for Union are derived from the trailing 12 months of historical booking performance for active comparable Airbnb listings in the market — they are not forward-looking projections.
