    What's special

    Exceptional daylight basement home
    Seller will pay for a Interest Rate Buydown, reducing your interest rate in the first year and the second years — saving you up to in mortgage payments and making homeownership significantly more affordable during your first two years. Welcome to your private Northwest retreat. This exceptional daylight basement home on 1.22 acres features a legal ADU of record with its own separate address and private entrance, offering outstanding flexibility for multi-generational living, guests, rental income, or a private home office. The thoughtful design provides separate living areas that balance connection and privacy. Two complete heating systems—one oil-fired and one wood-burning—offer year-round comfort, efficiency, and flexibility. Properties with a legal ADU, separate address, and private entrance are increasingly rare and highly sought after. Located on a quiet dead-end road with no HOA restrictions, you'll enjoy the freedom and privacy of country living while remaining just 15 minutes from Oregon City and Molalla shopping, dining, schools, and services. The 1.22-acre property includes a fenced pasture ideal for animals, gardening, or hobby farming. Towering second-growth fir and cedar trees provide exceptional privacy, filtered sunlight, and the timeless beauty of the Pacific Northwest. Take advantage of the seller-paid 2-1 Buydown—lower payments, thousands in savings, and more buying power from day one. This is a rare opportunity to own a versatile acreage property that combines financial savings, flexible living options, privacy, and Northwest character. PDF of 2-1 Buydown Example attached.
