Why can't house prices be out of tune with salaries
Your friends are overlooking a couple of problems with house prices and salaries being out of whack: Home 'equity' is a paper gain unless you realize it by selling the house. If you don't, but use the 'home ATM', all you're doing is piling up more debt that's secured on an asset that has downside risk. Ask anybody who's refinanced their house to buy a new boat or SUV in 2006/2007. In other words you're remortgaging the chickens before the eggs hatched. Of course they're also forgetting that all this debt will have to be paid back at some point, and that usually takes income, not equity. In a certain sense the housing market is a pyramid scheme that requires an influx of new buyers to maintain prices. Very simply, if you can't sell your house to buy a bigger one because the first time buyer you're trying to sell it to can't afford the down payment or the payment on the mortgage, then you can't sell your house to buy a bigger/better/nicer one and the next person in the chain can't sell his/hers. Cue the domino effect. House prices are only sustainable if people actually can afford to buy houses and if there's a massive disconnect between house prices and salaries, then house prices will fall eventually. It might just take a little longer depending on the amount of creative financing options that will eventually dry up.
