Condition Analysis
OVERALL CONDITION SCORE
Property is moderate renovation needed.
Built in 1905, this historic farmhouse is characterized by its original charm and antique features, such as reclaimed windows and a screened-in porch. While the property is functional and includes well-maintained amenities like a pool and guest studio, the main residence is aged and likely features outdated systems and a low bathroom-to-bedroom ratio. It meets the 'fair' criteria as a century-old home maintained through regular upkeep but lacking a comprehensive modern renovation.
PROSSTRENGTHS & OPPORTUNITIES

The property has a large lot size, which is more than 4 times of its living area. lot size in square feet = 3517034, living area = 5323.
- Expansive 80-Acre Estate

- Historic Architectural Character
The 1905 farmhouse is rich with original charm, featuring reclaimed antique windows from early 1900s San Francisco and a classic screened-in porch that enhances its legacy appeal.

- MLS Listing Discrepancy
Living area discrepancy between mls listing and other public or private record. mls listing living area = 5323, other record living area = 1808.
- Historic Maintenance Requirements
Built in 1905, the 5,323-square-foot main residence and expansive grounds likely require significant ongoing maintenance and potential infrastructure modernization typical of century-old estates.

About 3200 Castle Road
A Rare 80-Acre Sonoma Estate with Historic Farmhouse and Vineyard Behind the Gates of Bartholomew Park. Just minutes above the Sonoma Plaza, this one-of-a-kind 80-acre property offers the space, privacy, and character Bay Area buyers look for in a weekend retreat or long-term legacy home. At its center is a 5-bedroom, 2-bath farmhouse rich with original charm. Antique windows reclaimed from early 1900s San Francisco bring in natural light and nod to the home's history, while a screened-in front porch sets the tone for relaxed indoor/outdoor living. The land blends vineyard blocks with wide-open acreage, creating both beauty and potential. A large pool and pool house offer a resort-style escape, and a classic car barn with a guest studio above provides space for visitors, hobbies, or a private office. The views are incredible, hills, vines, and open sky in every direction. Properties with this kind of scale, warmth, and proximity to town rarely hit the market.
