Good
TeardownExcellent
Property is move-in ready.
Built in 1991 (33 years old), the property is well-maintained and marketed as move-in ready. While the kitchen and bathrooms retain some dated elements like white tile countertops and oak cabinetry, the home has undergone a significant cosmetic refresh with newer laminate flooring, modern lighting, fresh paint, and plantation shutters. The inclusion of a fully paid solar system and the functional, clean state of the systems elevate it from 'Fair' to 'Good'.
PROSSTRENGTHS & OPPORTUNITIES
- High Available Lot Utilization
The property has a large lot size, which is more than 4 times of its living area. lot size in square feet = 17976, living area = 2643.
- Expansive Lot & Development Potential
The massive 17,976 sq. ft. lot provides rare flexibility for RV parking, a resort-style backyard, or the addition of an ADU, offering significant long-term value and utility.
- Modern Turnkey Upgrades

- Lack of Scenic Views
Despite the premium price and large lot size, the property lacks any significant views, which is often a sought-after feature for homes in this price bracket.
