The finance side of things has also enabled a kind of house size inflation. Anecdotally, I've seen new tract housing go up in areas that need housing, which were all 3000 sq/ft each. They could have developed for higher density and sell more units, but I guess the margins are better on houses that sell for 700k and up. Especially if folks are willing to go into deep debt to pull it off. Plus that does little to ease demand, so the cycle can continue.
