Property is moderate renovation needed.
The property is well-maintained and move-in ready but features significantly dated interior aesthetics consistent with its 1979 build year. The kitchen retains older oak cabinetry and tile countertops, and the lower level includes dated drop ceilings and a spiral staircase. While major systems like the AC and decks have been updated or maintained, the overall style of the bathrooms, kitchen, and fixtures lacks the modern renovation required for a 'good' or 'excellent' rating.
The property has a large lot size, which is more than 4 times of its living area. lot size in square feet = 38698, living area = 2954.
Situated on nearly an acre across two parcels, this property offers exceptional privacy, serene hillside views, and a tranquil retreat-like atmosphere rarely found so close to town.
With two primary suites and a lower level featuring a separate entrance, office, and family room, the home is perfectly configured for multi-generational living or a professional home office.
Lot size discrepancy between mls listing and other public or private record. mls listing lot size in square feet =38698, other record lot size in square feet = 18225.
The kitchen and outdoor areas are plumbed for propane, which may require ongoing tank management and could be a drawback for buyers accustomed to standard natural gas connections.
The use of a spiral staircase to connect living levels and the 1979 construction may present mobility challenges or require updates to meet modern aesthetic preferences.
