Discover a rare and versatile investment opportunity in the heart of Oregon City. This carefully renovated 1940s bungalow has been expertly converted from a single-family home into a fully permitted duplex. It combines vintage charm with modern engineering. The property features two separate living spaces, each with its own private, keyless entry. This setup is perfect for multi-generational living or a high-end rental portfolio. The upstairs unit (418 Dewey St) offers about 950 square feet of bright living space. This two-bedroom, one-bathroom home has been thoughtfully updated with a modern kitchen that includes newer stainless steel appliances and a dedicated washer and dryer. Comfort is ensured year-round, thanks to a highly efficient mini-split system with three individual units for precise climate control. Below, the newly built downstairs unit (406 Irving St) provides an additional 500 square feet of modern luxury. This one-bedroom, one-bathroom space features a sleek layout with brand-new stainless steel appliances and a handy stacked washer with a ventless dryer. In addition to the aesthetic updates, the foundational aspects of this home are engineered for ultimate peace of mind. The property has new sewer and water lines, along with updated electrical work to support the dual-unit conversion. A strong French drain system with sump pumps protects the foundation, while a backup battery system with an automatic transfer switch keeps the downstairs unit and drainage systems running during power outages. With a roof that was replaced in 2019, potential RV parking, and all work fully permitted, this turnkey property showcases functional design and long-term value.
