Fair
TeardownExcellent
Property is moderate renovation needed.
Built in 2006, this 20-year-old property is a bank foreclosure showing clear signs of deferred maintenance, such as the dead lawn and unkempt exterior. While the interior features custom elements like coffered ceilings and marble, the kitchen and bathrooms are dated to the original construction and likely require minor repairs and cosmetic updates to reach modern standards.
PROSSTRENGTHS & OPPORTUNITIES
- All-Suite Bedroom Configuration
The property features five bedrooms that are all master suites, offering exceptional privacy and luxury for large families or multi-generational living.
- Custom Architectural Details
A grand foyer with a marble medallion, a spiral wood and iron staircase, and a gourmet kitchen with dual dishwashers provide a high-end 'mini mansion' aesthetic.
- Prestigious Location
Situated in the highly desirable Northeast Downey area, this 5,053-square-foot custom home is located in a top-tier neighborhood within the Downey Unified School District.
CONSRISKS & DEFICIENCIES
- Foreclosure Status
As a bank foreclosure, the property may have deferred maintenance or require significant cosmetic updates, and is likely sold without standard seller warranties.
- Unfinished Outdoor Space
Despite the large 10,284-square-foot lot, the property lacks a pool and established landscaping, requiring additional capital investment to maximize outdoor utility.
