The listing explicitly highlights a 'planned renovation' and the need to 'modernize the interior,' indicating that while the home is functional, the kitchen, bathrooms, and systems are outdated by current luxury standards and require significant cosmetic updates to reach their full potential.

The sheer scale of the 22,210-square-foot home and 100-acre grounds necessitates significant ongoing maintenance, staffing, and high utility expenditures.
As the property is positioned for a planned renovation, buyers must be prepared for the complexity and additional capital investment required to modernize the 1999-built interior.
