Condition Analysis

OVERALL CONDITION SCORE

Good
TeardownExcellent

Property is move-in ready.

The property is in move-in ready condition with significant recent capital improvements, including a brand-new Presidential roof and a new dual-zone Carrier HVAC system. While the home dates to 1947, it has been well-maintained and recently refreshed with refinished hardwood floors, updated kitchen cabinets, and new interior paint. The kitchen and bathrooms are updated and functional, and the addition of new pavers and landscaping enhances the overall quality. It falls into the 'good' category rather than 'excellent' because the renovations involve refinishing existing components rather than a complete modern gut-rehab of the 1940s structure.

PROSSTRENGTHS & OPPORTUNITIES

  • Versatile Studio & ADU Potential

    The property features a detached 364 SF vaulted-ceiling studio and a downstairs bedroom with a private entrance, providing excellent flexibility for a home business, guest suite, or conversion into a rental ADU.

  • Extensive Recent Capital Improvements

    Significant upgrades including a brand-new Presidential multi-layer roof, new dual-zone Carrier HVAC system, and refinished hardwood floors ensure reduced immediate maintenance costs and enhanced energy efficiency.

  • Prime Country Club Location

    Situated in the prestigious North San Gabriel Country Club neighborhood on a generous 10,400 SF lot, the home offers a high-status address with easy access to San Marino, Arcadia, and luxury amenities.

CONSRISKS & DEFICIENCIES

  • Fragmented Bedroom Layout

    The split configuration of three bedrooms downstairs and two upstairs may be less desirable for families with young children who prefer all sleeping quarters on a single level.

  • 1940s Era Infrastructure

    Despite modern surface updates, the 1947 original construction may still possess older underlying plumbing or electrical components that do not fully meet modern high-efficiency standards.
