This property with captivating views of Gifford Lake has a four-lot subdivision fully approved, so you could turn your back 40 (well, back 11-plus acres) into a nice little neighborhood, with multiple lakefront properties and sites for swimming pools. Included in the price is this six-bedroom, six-plus-bath 8,000-square-foot farmhouse built in 1817, which maintains the character of an era gone by, but is forward-thinking, too, with every modern amenity for the 21st century. Want to buy the house separately? It’s just $2.95 million and set on just under 3 acres. Agent: Brian Milton, Houlihan Lawrence, 914-273-9505, ext. 302
