This Quadruplex Investment presents a Prime Investment Opportunity with a List Price of $1,250,000—positioned well below the $1,309,768 Fair Market Value by 4%. This valuation gap offers $59,768 in Instant Equity for strategic buyers. While currently holding a Condition Rating of 4, the asset features Panoramic Carquinez Bay Views, a new roof, and new windows. The absence of local rent control allows for immediate rent stabilization through interior updates. This is a high-yield acquisition for Buy-and-Hold Investors or Value-Add Specialists.
Property is moderate renovation needed.
Built in 1964, the property is described as a 'value-add' opportunity requiring interior updates to achieve market rents. While it features a new roof and windows, the lack of interior photos and the agent's description of 'vintage infrastructure' suggest that the kitchens, bathrooms, and flooring are likely dated and in need of modernization, fitting the criteria for a property that is functional but shows signs of age.
The absence of local rent control combined with a value-add profile allows for rapid rent stabilization and increased ROI through strategic interior updates.
The property offers rare and stunning dual views of the Carquinez Bay and Martinez Valley, significantly enhancing tenant desirability and long-term asset value.
With a newly installed roof and windows, the property reduces immediate capital expenditure requirements and improves energy efficiency for the incoming owner.
To achieve full market rents and realize the property's potential, an investor will need to budget for interior modernizations across all four units.
Built in 1964, the property may require ongoing maintenance or system updates typical of mid-century multi-family buildings despite recent exterior improvements.
