There's quite a few untouched Mid Century ranchers
in Upstate NY... much of which has been in slow economic decline since the '70s. That led to many '50/60s houses that were never modified or "upgraded" due to economic concerns. Our area was very prosperous and ranchers and capes of all sizes proliferated up until the late '60s when IBM, which started here, began leaving and Endicott-Johnson shoes, once the world's largest shoemaker, imploded, both shedding over 20,000 decent jobs ,just in this county. We own 2 little ranchers, one 900 sq ft, one we live in 1100 ft, not counting basements, with most, or all, of the original details, the smaller one being completely untouched with some cool features like glass blocks, knotty pine kitchen, original wood swing out horizontal windows, all wood floors etc. etc.
But they didn't leave any old appliances, except a '70s Westy FL I stupidly got rid of (I was very unenlightened back then!)
