Condition Analysis
See Full ReportOVERALL CONDITION SCORE
Poor
TeardownExcellent
Property is extensive renovation needed.
Built in 1947, this 77-year-old cottage exceeds the 30-50 year threshold for a major rehab. The interior shows dated wood paneling and older fixtures, and the listing description emphasizes the land value and 'possibilities to update or expand,' suggesting that the primary systems and kitchen/baths require significant modernization.
PROSSTRENGTHS & OPPORTUNITIES
- High Available Lot Utilization
The property has a large lot size, which is more than 4 times of its living area. lot size in square feet = 42253, living area = 1020.
- Expansive Lot & Development Potential
The property sits on nearly an acre of land with generous level grounds, offering a rare opportunity for significant expansion, ADU construction, or a complete custom rebuild in a high-value area.
- Prime Historic Location
Located in the prestigious New Almaden hills, the home offers a unique blend of rural privacy and community charm, with immediate access to top-rated schools and miles of trails at Almaden Quicksilver County Park.
CONSRISKS & DEFICIENCIES
- MLS Listing Discrepancy
Lot size discrepancy between mls listing and other public or private record. mls listing lot size in square feet =42253, other record lot size in square feet = 20400. Living area discrepancy between mls listing and other public or private record. mls listing living area = 1020, other record living area = 988.
- Limited Living Footprint
With only 1,020 square feet of living space and a single bathroom, the current configuration is quite modest for the price point and may require immediate expansion to suit modern family needs.
- Aging Infrastructure
Built in 1947, the cottage likely requires substantial updates to its core systems and interior finishes to meet contemporary standards, adding to the overall investment cost.
