Estimated Market Value
Condition Analysis
OVERALL CONDITION SCORE
Property is moderate renovation needed.
Built in 1998, this large estate shows signs of its age, particularly in the interior finishes. While the kitchen features dual islands and custom cabinetry, the white appliances, light fixtures, and overall aesthetic appear dated. Bathrooms also feature older styles with gold-framed showers and vanity lighting. The extensive use of green carpet throughout many living areas and bedrooms, along with some wallpaper choices, indicates that the property has not undergone significant modern renovations within the last 15-20 years. While well-maintained and functional, it requires substantial cosmetic updates to meet current quality and style standards, aligning with the 'fair' category criteria.
