Listing description

This proposed 20-acre property is a once-in-a-generation opportunity to own a private estate in West Marlborough Township. "Hamilton Farm" is a proposed twenty-acre subdivision that is surrounded by several hundred acres of similarly eased farmland. This ultra-private estate home is currently part of a three-hundred-acre parcel and a Brandywine Conservancy Easement protects the entire acreage. The house is currently the only existing residence on the property. The conservation easement has been thoughtfully planned to afford the ultimate in privacy, with the entire three hundred acres having already been limited to one additional primary residence, two secondary residences, and three attached apartments. Located in the countryside of southern Chester County, this hidden 4 bedroom, 2.1 bath retreat lies within the boundaries of the Unionville Chadds-Ford School District yet you are still convenient to Wilmington, Philadelphia & the I-95 corridor. The Kitchen, Dining Room, and Living Room are perfect for hosting the most formal of events or intimate family gatherings. On the 2nd floor, the Primary Bedroom Suite with a primary bath offers ample closet space. All four bedrooms on this level offer amazing views of the preserved farmland. The Third Level offers a large Bonus Area that could make a great art studio, playroom, or office space. Outside the home, you are surrounded by hundreds of acres of protected land, and your nearest neighbor is likely to be of the four-legged variety. The property is serviced by a propane-powered generator if there is a loss of power. A two-car detached garage with electricity and water sits adjacent to the house as well as the remnants of an old bank barn and silo. Do not miss this rare opportunity to own a piece of heaven. There is the possibility that additional acreage could be acquired. Please inquire with the listing agent for subdivision and conservation details. Please schedule an appointment before entering the property.

Assessment note: this home is assessed at $247,330, well below the ~$917,400 its asking price implies at Chester County's common level ratio (30.6%). A sale near asking can invite a school-district assessment appeal that could raise the bill by roughly $26,182/year. Worth pricing in.

Recomputed from the county assessment ($247,330, 1998 base year) × current millage. Portals typically reprint the recorded 2024 bill. Pennsylvania does not reassess on sale. Estimate only. Verify with Chester County before relying on it. Learn more: PA property tax calculator · Common Level Ratio by county.

Taxes use NookLocal's estimate at current millage rates, not the stale figure on the MLS. The default rate is the average 30-year rate as of July 2026; insurance is estimated at 0.35% of the price per year. Below 20% down, lenders usually add mortgage insurance, which this estimate doesn't include. Estimate only; verify before relying on it.
