Built in 1976 (48 years old) and explicitly marketed for land value only. The listing specifies 'as-is' condition, no repairs, and cash buyers only, while highlighting expired plans for a 15,000 sq ft replacement estate, indicating the current structure is obsolete and intended for demolition.
The property has a large lot size, which is more than 4 times of its living area. lot size in square feet = 79844, living area = 3802.
Elementary School: Quail Summit Elementary School (9/10). High School: Diamond Bar High School (10/10).
The expansive 1.83-acre lot is fully usable and elevated, featuring prior city-approved plans for a 15,000 sq ft luxury estate, making it a premier canvas for developers or custom home builders.
The requirement for cash-only buyers and a strictly 'as-is' sale significantly limits the pool of potential purchasers by excluding those dependent on traditional financing.
As the property is sold primarily for land value, buyers must budget for the substantial costs of either a total redevelopment or extensive renovations to the existing structures.
No exterior & parking available.
