This design was released ~1910[1]. Average income was around $574/year.[2] This house would've cost 4-5 years income just for the parts to be delivered to the plot of land you didn't own yet. (at the 1916 price of $1663)

You can buy a LOT more house these days relative to annual incomes mostly because comparative incomes across the board have risen substantially, and interest rates are so much lower. That said, the cost of the lot and the labor would've been cheaper to finish the house back then so that's something!
