Quote from CaptainObvious:
We had it in the 90's. Great while it's working. Not so much when the tab comes due, as evidenced by the 30's and 2000's. The vig will be collected sooner or later.
If you think about it even a relatively prudent 20% down on a house is a leveraged short on the currency, since the house price over the long term only goes up by inflation, which looked at another way is the value of the currency going down against the value of the house.
Any time you borrow something and invest the proceeds somewhere else, then collect it later, you're shorting something; in this case it's the - take your pick - USD, GBP, EUR. Leveraging the short (20% is five times leverage; can't do that with a stock but can in a house, which is probably one good explanation for why so much money went into houses) increases the profit when it works, of course.
So, lucrative when it works, hell when it doesn't.
