Despite being built in 1980, this property has undergone extensive and high-quality renovations, aligning with the 'extensively renovated within 5 years' criteria for an excellent score. The main house features new hardwood flooring throughout, a 'state-of-the-art gourmet kitchen' with stainless steel appliances, sleek new cabinetry, and modern fixtures, all confirmed by the images. The bathrooms are also fully updated with contemporary vanities, tiling, and glass showers. Additionally, the two ADUs boast updated kitchens and bathrooms. While the listing notes a potential weakness regarding the age of core systems (plumbing, electrical, HVAC) and the absence of central AC, the visible and described components are virtually new and meet current quality standards, indicating minimal physical depreciation in the renovated areas.
