Lummi Island, WA Airbnb Market Data, Statistics, and Occupancy Rates

Lummi Island Short-Term Rental Market Overview

Average annual revenue sits at $35,912 against an average home value of $994,167, which means cash-flow margins are tight and investors need to be strategic about acquisition pricing. The market's strong summer seasonality — August peaks near $4,891 per month — offers meaningful upside for well-positioned properties, though occupancy at 23% trails the Washington state average of 36%. With a 186% year-over-year growth in active listings, competition is ramping up quickly on this small island.

Why Investors Consider Lummi Island

Lummi Island draws investor interest as a unique, supply-constrained island getaway with premium nightly rates, though high home prices and seasonal demand require careful underwriting.

Expert Market Assessment

"Lummi Island presents a competitive opportunity where selective deal sourcing matters more than in most markets. The combination of nearly $1 million average home values and sub-$36K annual revenues creates a revenue-to-price ratio that's below average, meaning investors need to find properties priced well below the market mean or with clear upside potential. Seasonality is pronounced — revenue more than doubles from its October–November lows to the August peak — so cash reserves for carrying costs during the quieter months are essential. That said, the island's exclusivity and small listing count give well-run properties a real chance to capture outsized share during peak summer demand."

Key Airbnb Metrics & Trends in Lummi Island

Average revenue by month in Lummi Island

Lummi Island's revenue pattern is sharply seasonal, with August ($4,891) and July ($4,621) generating more than double the revenue of the slowest months like November ($2,200) and October ($2,260). Investors should plan for a roughly $2,600 swing between peak and trough months, with meaningful revenue concentration in the June–September window.

Active Airbnb listings by property size in Lummi Island

Supply on the island is concentrated in just two property sizes: 2-bedroom units (8 listings) and 3-bedroom units (6 listings). The absence of 1-bedroom or 4+ bedroom listings in the data could signal either limited housing stock in those sizes or a potential niche for differentiated offerings.

Average daily rate (ADR) by property size in Lummi Island

ADR nearly doubles from 2-bedroom properties ($205) to 3-bedroom listings ($372), representing an 81% premium for one additional bedroom. This steep jump suggests strong group and family demand willing to pay significantly more for extra space on the island.

Average RevPAN by property size in Lummi Island

Three-bedroom properties deliver a RevPAN of $81 compared to $52 for 2-bedrooms, a 56% advantage that accounts for both rate and occupancy. This makes larger homes the more efficient revenue generators on a per-available-night basis despite their slightly lower occupancy.

Average occupancy rates by property size in Lummi Island

Two-bedroom listings edge out 3-bedrooms in occupancy, 26% versus 22%, suggesting smaller units are slightly easier to fill consistently. However, both sizes fall well below the state average of 36%, underscoring the seasonal nature of island demand.

Average monthly revenue by property size in Lummi Island

Three-bedroom properties earn $3,758 per month on average — roughly 48% more than 2-bedroom units at $2,531 — thanks to their substantially higher nightly rates. For investors weighing acquisition costs, the monthly revenue gap between these two configurations is a key input for cash-flow modeling.

Average annual revenue by property size in Lummi Island

At $45,102 per year, 3-bedroom properties significantly outperform 2-bedroom units ($30,383), generating nearly $15,000 more annually. Given the island's high home values, the 3-bedroom configuration likely offers the stronger path toward covering carrying costs, though investors should verify the price differential between property sizes.

Most common amenities for Airbnb listings in Lummi Island

Parking and kitchens are near-universal at 96%, followed closely by BBQ grills (91%), reflecting guest expectations for self-sufficient, outdoors-oriented stays. Notably, 52% of listings allow pets and 44% offer hot tubs — amenities that can help differentiate a property in this small, competitive market.

Understanding Lummi Island's ROI Score: 46/100

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

Lummi Island's ROI Score of 46 out of 100 places it in the Competitive Opportunity tier, reflecting below-average marks on revenue-to-price ratio, occupancy stability, and market growth trend, with only supply/demand balance rated as average. The high average home value relative to revenue is the primary drag on the score, meaning investors need to find favorable entry points or add meaningful value to make the numbers work. Pairing this data with thorough local regulatory research and a realistic off-season cash-flow plan will be critical before committing capital.

Short-Term Rental Regulations in Lummi Island

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

Permit Requirements

Short-term rental operators on Lummi Island should verify whether Whatcom County or Washington State require STR permits, business licenses, or registration before listing. Investors are encouraged to consult directly with local planning and zoning authorities to confirm current requirements.

Key Restrictions

Common STR restrictions in island and rural Washington communities can include occupancy limits, minimum night-stay requirements, noise ordinances, and parking regulations. HOA or community covenants may impose additional limitations, so reviewing any applicable deed restrictions before purchasing is essential.

Tax Obligations

Washington State imposes lodging taxes on short-term rentals, and Whatcom County may levy additional local excise or tourism taxes. Platforms like Airbnb often collect and remit some of these taxes automatically, but hosts should verify they're meeting all state and local obligations.

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

Future Outlook & Long-Term Forecast

"Over the next 12–18 months, Lummi Island's STR landscape will likely be shaped by the rapid supply increase already underway. With listings nearly tripling year-over-year, occupancy rates could face additional pressure unless demand keeps pace, potentially settling in the 20–25% range. Summer months should continue to drive the bulk of annual revenue, with July and August ADRs holding steady or rising modestly by 1–3% as the island's appeal to nature-seeking travelers remains intact. Investors should budget conservatively and plan for meaningful off-season revenue dips, particularly from October through April."
