Condition Analysis

OVERALL CONDITION SCORE

Fair
TeardownExcellent

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.

    The sheer size of the estate (10,232 sqft home, 38,166 sqft lot) with a resort-style pool, spa, and extensive landscaping will incur substantial ongoing expenses for upkeep and utilities.

  • Monthly Association Fees

    A monthly association fee of $308.0 adds to the recurring ownership costs, which potential buyers must factor into their budget.
