Investment Insights

Based on property information with market context.

Ranch duplex consisting of a main home plus a detached second unit on a single lot. The main house was expanded to approximately 1,466 square feet with 3 bedrooms and 2 full bathrooms, retaining much of its original 1950s character. Improvements include a new roof, new carpet, and fresh interior paint, along with upgrades such as an on-demand hot water heater, dual pane windows, a walk-in tub, and central air-conditioning.

The detached rear unit is approximately 650 square feet with 2 compact bedrooms and a newer mini-split system for heating and cooling. The unit also has a sub-meter for electricity usage. Both dwellings are officially zoned as a Duplex, served by a private well with UV filtration, and connected to City sewer (new owner to verify the possibility of connecting to City water).

The property sits on a 0.4063-acre lot with generous parking areas for an RV or toys/work truck, plus a detached garage and a detached workshop. The listing notes close proximity to schools, parks, shopping, and dining, with mature landscaping and yard space for current enjoyment or future improvements.
