Built in 1900, this property features residential units with significantly outdated finishes, including a dated bathroom with basic tile and fixtures, and old patterned carpets. The 'roughed-out' ADU requires substantial completion, indicating a major rehabilitation project. While a new 400 amp electrical service is a positive system upgrade, the overall aesthetic and functional condition of the living spaces, coupled with the unfinished ADU, suggest the property requires substantial repairs and modernization to meet current standards.
Pros & Cons

Pros

Prime Location: Situated in the highly desirable and vibrant Mission District of San Francisco, ensuring strong tenant demand and potential for appreciation.
Significant Income Upside: Offers approximately 60% upside in the current rent roll by bringing existing units to market rents and completing the ADU, presenting substantial growth potential for an investor.
Immediate Cash Flow & Diversification: The property is 100% occupied, providing immediate and stable income from a diversified mix of three residential units and one ADA-compliant commercial space.
Approved ADU with Value-Add Potential: Includes a shovel-ready, roughed-out ADU with planning department approval, offering a clear path to adding significant future income and increasing property value.
Efficient Operating Expenses: Benefits from a new 400 amp electrical service and separately metered water, contributing to lower and more efficient operating costs for the owner.

Cons

Additional Capital Investment Required: The ADU is partially completed and 'awaits finishing by a future owner,' necessitating additional capital expenditure and project management to realize its income potential.
Below Market Rents: The stated '60% upside in the current rent roll' indicates that existing rents are significantly below market, which may require strategic planning, tenant negotiations, or potential challenges to achieve market rates.
Age of Property: Built in 1900, the property is over a century old, which could imply potential for deferred maintenance, older building systems (beyond the new electrical), or higher ongoing repair costs.
