Fair
TeardownExcellent
Property is moderate renovation needed.
Built in 1950, this duplex is over 70 years old and shows significant signs of age despite 'in process' updates. While the description mentions new floors and counters, the photos reveal dated wall heaters, older cabinetry, and worn exterior concrete. The property is functional but requires further modernization of systems and finishes to move beyond a dated status.
PROSSTRENGTHS & OPPORTUNITIES
- Dual-Income Potential
As a duplex, this property offers excellent flexibility for 'house hacking' to offset mortgage costs or for investors to maximize ROI by leasing both units in a high-demand rental market.
- Recent Interior Updates
The upstairs unit is undergoing significant improvements, including new flooring, updated kitchen counters, and new appliances, providing immediate value-add and reducing initial maintenance costs.
- Strategic Commuter Location
The property is ideally situated near downtown Antioch with easy freeway access and proximity to BART, making it highly attractive to commuters working across the Bay Area.
CONSRISKS & DEFICIENCIES
- Low School Ratings
The local assigned schools have low performance ratings (ranging from 2 to 3), which may deter long-term family tenants and impact future resale value.
- Vintage Infrastructure
Built in 1950, the property may have aging systems or structural elements that require more frequent maintenance compared to newer residential income properties.
About 709 W 8th St
What you've been waiting for! Live in one unit and rent the other (let the tenant pay a large portion of the mortgage!) Or rent both units for maximum ROI. Upstairs unit has updates in process: new floors, new kitchen counters, refinished cabinets and new appliances. Nice sized units, close to shopping and downtown activities. Easy freeway access and short drive to BART. Both units have indoor laundry rooms and large, open kitchens. Great opportunity. Come See!
