Amazing opportunity for a home plus income! The attached ADU brought in $29k in net income in 2025 and features a strong forward booking calendar, creating immediate revenue opportunity for the next owner. Tucked into 3 secluded acres with unobstructed views of Sauk Mountain, this private Skagit Valley retreat offers a rare combination of North Cascades beauty, usable acreage, and proven income production. Originally rooted circa 1900, the main residence was thoughtfully built in 1995, blending character with the comfort and functionality. Beamed ceilings, warm wood floors, and walls of windows create an inviting atmosphere that captures the surrounding mountain views, mature evergreens, seasonal creek, and wide-open skies. The open concept main level is ideal for gathering, while the upper-level primary suite serves as a true retreat, featuring a private balcony overlooking Sauk Mountain, a clawfoot soaking tub, and an oversized shower. The attached ADU offers flexibility to continue operating as a turnkey vacation rental, accommodate multi-generational living, or provide private guest quarters. Outside, the property is equally impressive with expansive garden space, fruit trees, pasture potential, and multiple outbuildings, including a garage and detached studio ideal for hobbies, guests, workspace, or future rental conversion. Properties offering this combination of privacy, acreage, iconic North Cascades views, and established income potential rarely come to market.
