PB (and J -sorry, it's Friday):
You know where I stand on this. The conservative view is that house prices will stay flat. If that is the case, then you are simply renting (paying the bank instead of a landlord) and still have to take care of the property yourself. Furthermore, you lose the ability to invest the liquid assets that I presume you currently possess. Instead getting 5% return on your investment, you'll have to pay someone 6 percent for an investment that will not appreciate for at least 2 to 3 years. Of course, it gets worse if housing prices go down.
My bottom line is that whether you should buy depends on why you are buying. If you found a house that you love and would be happy to stay in for a while, go for it. But if you are buying with as a way to investment, I just do not think the economic signs support a purchase.
