And that excludes the cost of the land on both.
During the 1950's my clients used to build two or three small houses each year for $7,500 each including profit and the cost of land.
Today my former clients (I am retired) build up to 20,000 houses each year for slightly less on a Sq. Ft. basis. As I stated in my last post to you, the increase in the price of the house is due to the fact that local and state governments extort fees from the developer and the fact that your money is no good.
I can still build you the same house I build in the 50's for the same price, but you will have to pay for it in the same money.
