Investment thesis

This Sinclair Island property stands out as a distinctive STR investment due to its direct waterfront location, private beach access, and off-grid infrastructure, all of which appeal to guests seeking a secluded Pacific Northwest experience. The underwriting model, based on a $548,500 purchase price, projects robust income and cash flow, making it attractive for investors prioritizing yield. The property is offered turnkey, reducing initial setup time and costs. However, the island setting and off-grid systems introduce operational complexities that require experienced management or a willingness to engage with non-traditional logistics. The most important caveat is the need to confirm ongoing STR regulatory compliance and the sustainability of off-grid utilities for guest turnover.

Risks

STR permitting: verify local ordinance and zoning allow short-term rental at this address before offering. Not verified.
STR regulations and island-specific restrictions should be verified
Operational complexity due to off-grid systems and remote access
Returns are sensitive to occupancy and ADR assumptions given the niche location
Potential for higher maintenance costs due to waterfront exposure and off-grid infrastructure
Seasonal demand swings may impact occupancy and pricing
Limited buyer pool for resale due to unique location and property type

Market

Anacortes and the surrounding San Juan Islands are known for their scenic waterfront properties and appeal to vacationers seeking natural beauty and seclusion. The STR model is supported by strong regional tourism, but the island's remote nature and off-grid requirements mean the guest pool is more specialized. The underwriting model is high-confidence, but investors should be aware of the unique operational and regulatory environment of island STRs.

Neighborhood

Sinclair Island offers a secluded, natural setting with direct water and mountain views, appealing to guests seeking privacy and outdoor recreation. The area is characterized by low-density development and limited access, with transportation via private boat, airstrip, or foot ferry. While this enhances the property's appeal for certain guest segments, it also means lower confidence in broad-based demand signals compared to more accessible markets.

Underwriting notes

At a $548,500 purchase price, the underwriting model projects a monthly expected income of $5,929 and cash flow of $1,702, with an 18.6% cash-on-cash return, assuming a 57% occupancy rate and $342 ADR. Operating expenses are estimated at 25% of income, with no management fee assumed. These figures are high-confidence, but are sensitive to occupancy and nightly rate assumptions, which may fluctuate due to the property's remote, seasonal, and off-grid nature. Investors should confirm the sustainability of these assumptions and the operational feasibility of STR management on Sinclair Island.
