Fair
TeardownExcellent
Property is moderate renovation needed.
Built in 1960 and held by the same owner for over 35 years, the property is functional but dated. Kitchens show various stages of age with older tile countertops and cabinetry; popcorn ceilings are present throughout. The presence of window AC units indicates a lack of modern central HVAC systems, and the overall interior condition requires cosmetic and system updates to meet current market standards.
PROSSTRENGTHS & OPPORTUNITIES
- Great Schools
Elementary School: Hyer Elementary School (10/10). High School: Highland Park High School (9/10).
- Significant Rental Upside
With all four units currently on month-to-month leases, investors have a rare opportunity to immediately transition rents to market rates or renovate units to maximize cash flow.
- Prime Coastal Investment Location
Located in the high-demand Westside Costa Mesa market, the property benefits from close proximity to beaches, dining, and shopping, ensuring consistently low vacancy rates.
CONSRISKS & DEFICIENCIES
- Vintage Infrastructure
Built in 1960, the property may require significant capital expenditures for modernizing major systems like plumbing, electrical, or roofing to meet current standards.
- Compact Living Spaces
The total building size of 2,512 square feet results in relatively small average unit sizes, which may limit the ability to attract tenants looking for more spacious floor plans.
