"This house would have had vinyl floors"
This house had hard wood floors. The original floors were, in fact, restored, as were the knotty pine walls.
The picture of the kitchen appears to have a vinyl floor.
I was originally unaware that the $1.8 million included the additional outbuildings, etc. The article did not mention this, my guess is that if it had been the Stainmiester's childhood house, there would have been extensive explanations of why the cost of refurbishing a house that probably was once on wheels cost so much.
