Not only does this estate date to the 18th century, it was also cited in colonial-era maps created by General George Washington’s chief cartographer, Robert Erskine, said the seller, financial analyst Timothy Brackett.

And now, the spread — originally known as Halstead Farm — is listed for $3.9 million, slightly down from the $3.95 million it asked last summer, according to Zillow.

What’s more: There’s even a cryptocurrency discount for anyone who wants to pay in Bitcoin. 

The estate, at 358 and 364 Crescent Ave. in Wyckoff, NJ, has a Federal- and Greek Revival-style main house with four bedrooms.

Despite its age, it’s modernized within — with historical details intact.

There’s also a renovated two-bedroom, two-bathroom carriage house, which currently serves as an income-generating property, and a one-bedroom, one-bathroom stone cottage.

The latter was formerly the gate house to a nearby country club until it was moved to this location — and it can be used as an office, gym, or artist’s studio.

Brackett’s father, Warren, originally purchased this estate in 1946 for $40,000, about $537,000 in today’s figures, with 13 extra acres that the family gifted to the town in 1993 that are now “The Gardens of Wyckoff” — a nature sanctuary.

The total acreage now is roughly 4.

The property is grandfathered for horses and small livestock — and there’s also “deep pure well water, affording a self-sustaining haven,” a pool and a private pond stocked with fish.
