Condition Rating
Poor

Built in 1963, this triplex is over 60 years old with no mention of significant interior renovations. The MLS analysis explicitly highlights 'Unknown Interior Condition' and the potential need for 'significant capital expenditures on major systems' (plumbing, electrical, roofing). Images reveal older windows and visible window AC units, indicating outdated cooling systems. While the exterior has been recently painted, the interior and major systems likely require substantial repairs and rehabilitation to meet modern standards and tenant expectations.
Pros & Cons

Pros

Income Potential & Flexibility: The triplex offers significant upside potential with all units currently on month-to-month leases and rents below market value, allowing for immediate rent adjustments and tenant management flexibility.
Desirable Location: Located in a desirable Altadena area, the property provides convenient access to hiking trails, shopping, dining, parks, schools, and major freeways, with easy commutes to Pasadena and Los Angeles.
C2 Zoning Versatility: The C2 zoning offers exceptional versatility for investors, owner-occupants, or developers, allowing for potential future commercial uses or redevelopment, enhancing long-term value.
Separate Utilities: Each unit features separate gas and electric meters, simplifying utility management for the owner and promoting tenant accountability for their usage.
Tenant Amenities & Recent Updates: The property includes practical amenities such as four covered carport spaces with overhead storage, a shared laundry room, a large separate storage room, and a recently painted exterior, adding value and convenience.

Cons

Age of Property: Built in 1963, the property is over 60 years old, which may indicate a need for significant capital expenditures on major systems (e.g., plumbing, electrical, roofing) that are not explicitly mentioned as updated.
Unknown Interior Condition: While the exterior was recently painted, the description lacks details on the interior condition or updates of the units, suggesting potential for substantial renovation costs to modernize and maximize rental income.
Lack of Cooling System Mention: There is no mention of air conditioning or any cooling system for the units, which could be a significant drawback for tenant comfort and marketability, especially during warmer months in Southern California.
