Property is moderate renovation needed.
Built in 1950, the property is significantly dated with kitchens and bathrooms appearing to be 20-40 years old. While the addition of solar panels is a plus and the units are functional, the interior finishes, worn flooring, and aged cabinetry require substantial cosmetic updates and likely system modernizations to meet current market standards.
The property is delivered vacant, providing a rare opportunity for investors to immediately secure market-rate tenants or for owner-occupants to move in without the complications of tenant relocation.
Sitting on a large 6,500 sqft lot with a detached garage and 'room to expand,' there is clear potential for an ADU (Accessory Dwelling Unit) or further development to maximize rental income.
The inclusion of solar panels offers long-term utility savings, while the combination of a detached garage and ample off-street parking addresses a high-demand need in Central Vallejo.
Built in 1950, the property may require updates to major systems or cosmetic renovations to meet modern standards and command premium rental prices.
