In September we bought an 1890 farm house with a nice barn and a few acres. It was quite overgrown and hadn't been lived in (by humans) in many years.
There really is a house in there but over a few decades the bushes had become trees and you couldn't even use the front steps anymore.
So I started by clearing away the overgrowth so the house could be seen. Then I replaced the furnace, water heater, windows and plumbing. We got lucky because the wiring was upgraded in the late 70's (though it still only had a 100amp service)
But the real reason why I bought it was for the barn.
