About this home

Dream of living on Fir Island? Enjoy a beautiful 1.85± acre property with forest pathways, large garden space, outbuildings and carport. This 1928 home needs love, but has wood floors throughout, walk-in pantry, cool Timberline wood stove and full 1,368± SF basement. Cool outbuilding was an artist studio for years. Walk winding pathways through a forest of native trees and shrubs planted a few years ago to see a full view of Mt. Baker across Skagit Valley. Sit and watch ducks swim in the slough!
