Do you think it was surplus?
I ran across this house in the real estate, in a depressed area, and a sibling nearby. The sibling is sealed and bank owned, and either can be had for less than the price of a typical car. They are tiny at about 650 sq ft.
Anyway, to my knowledge these are post war development houses about 65 years old or so. (One of the postings says 85 but I don't think this area was developed in the 20s and these don't look quite right for that.)
But look at what is in the bathroom of the sealed house. Do you think that since these houses were built fast and cheap that they used new old stock?
Related to bathroom things, I was in the teenage home of a friend of mine, bought new in 1977 when she was almost done with HS. I was really surprised because the bathrooms were pure 60s as far as I was concerned, one blue and one yellow (not harvest gold). Fixtures and text tile floors. Again these houses were not well built (although the area is pricey) and the developer had certain...connections apparently and I was wondering if he too bought up a lot of old stock.
