wrong opinion:
The house price is 4-8 times of individual annual income. If house price increase at the same rate as income, the owner takes a lot of advatage of using bank's money (loan) which is much more than your existing asset to generate profit. This is why a few years a go, people whover can get a loan bought a house because the market created free money. It is like a game either you are priced out or catch up this last train if you can .....
But opposite is true (where we are right now), if the house market is down, you are losing your real equity money (down payment) much faster.
