@Gbudd The problem with that reasoning is that a house 20 or 40 years ago is not comparable to a house today. To put it into perspective just a modern day next thermostat 40 years ago would have cost you more than the entire cost of a modern home.
If you were willing to accept a 100 year old or 40 year old home in terms of safety standards, lack of tech, lead paint, and all of the other aspects you can get a dirt cheap home.
The truth of the matter is simply that you cant compare an education or a home from the past to one in modern day, they are not the equivalent
