    What's special

    Cozy by the fireplaceUninterrupted east-to-west water viewsUpdated walk-in showerTankless water heaterNew electrical panelLarge attic spaceStriking white spiral staircase
    This home hasn't been on the market in 40 years — a rare, floating home on North Portland Harbor with uninterrupted east-to-west water views, sunrises and sunsets right from your own dock, and a view of Mt. Hood to top it off. Original wood paneling runs throughout, and the living room has a gas fireplace along with a striking white spiral staircase — with a lit water feature at its base — leading up to the second level. The upstairs bedroom is oversized and works equally well as a second bedroom or a family room. There's also a large attic space, previously used as an office, that could easily become a third bedroom, playroom, office, or extra storage. A 3/4 bath rounds out the 2nd level.The kitchen has been updated with a glass tile backsplash, gas cooktop, and Bosch built-in microwave & oven.The primary bdrm is on the main w/ a ensuite bath that has an updated walk-in shower. Other recent updates include a tankless water heater and a new electrical panel (spring 2026). The home carries a 4-float rating with log and steel stringers (report upon request). Beyond that, it's ready for a new owner's cosmetic touch — solid bones, original details, and room to make it your own.This is life on the water, in every season. Warm days are made for paddleboarding or kayaking straight from your home down to the Island Cafe for lunch, and a short boat ride puts you in the main channel of the Columbia for some of the best fishing around — or just fish right off your own front deck. Come winter, watch the rain and fog roll over the river while you stay cozy by the fireplace, and every December this home has a front-row seat to the iconic Portland Christmas Ship Parade — the perfect excuse to host your holiday party. Located in the Tomahawk floating home community: a gated, self-run HOA that keeps dues low, and an active Yacht Club with reciprocal privileges at yacht clubs worldwide. About 15 minutes to PDX, 10 minutes to downtown Portland, and 5 minutes to downtown Vancouver, WA.
