Why can't house prices be out of tune with salaries
There's a few things going on here. If we fixed rates (and terms) over time we'd expect a pretty tight chart of home prices to income, almost lockstep. Add a layer of growth above that in boom times due to the wealth effect (when stocks are way up, we have extra money to blow on bigger houses) and the opposite when markets are down. Next, the effect of rates. With long term rates dropping from 14% in 1985 to 5% in 2003, the amount that can be bought for the same monthly payment rises dramatically as rates fall. Easy to lose site of that and the fact that the average size house has increased about 1.5% per year over the last 40 years, surely that can't continue.  When you normalize all these factors, houses cost fewer hours-worked almost at the peak of the market than 25 years ago. Mike's logical example of extrapolating out is very clever, I like it. In the short term, we'll see periods that are booms and busts, but actual prices will straddle the line representing the borrowing power of a week's pay.
