    Overview

    This duplex income property includes two residences at 21419 & 21503 Sir Walter Lane, each built out on three levels. Each unit features 3 bedrooms and 3.5 bathrooms, along with a 2-car garage, providing a practical layout for tenants seeking more space and privacy across multiple levels.
