Built in 2011, this 13-year-old property fits the 10-20 year 'Good' criteria. The kitchen is well-maintained with solid granite countertops and stainless steel appliances. The home features functional dual-zone HVAC systems and modern interior finishes like updated flooring, appearing move-in ready with no immediate major repairs needed.
With over 4,200 square feet of living space, five bedrooms, and a bonus loft, this property provides exceptional scale and flexibility for multi-generational families or home-based businesses.
The large 10,021 sq. ft. lot includes a low-maintenance stamped concrete backyard with mature fruit trees and essential side-gated access for RV or boat storage.
Built in 2011, the home features contemporary dual-zone heating and cooling systems and a grand primary suite with a private retreat, offering modern comfort and efficiency.
The conversion of the third-car tandem garage into a studio or storage room reduces the available covered parking for vehicles, which may be a drawback for some buyers.
The backyard is primarily finished with stamped concrete; while low-maintenance, the lack of a traditional lawn may be less desirable for buyers seeking a soft-scape garden area.
