> Whether I'm paying $2,000 to the bank, or $2,000 to some landlord (Really, I'd be looking at $2,800/month for a house like what I have now), I'm paying $2k/month. So why not just keep paying my mortgage, even if the value is less than what I paid?
I think you're missing the point that in a crash like 2008 the market rents would go from $2,800 to $1,400. Also, a reminder to anyone reading this that you cannot compare mortgage payments to rents. The down payment could have gone into another investment (like a tax-advantaged 401k) and so you need to take into account the opportunity cost of not getting S&P 500 returns. In the US, this is normally offset by the fact that the government tries to make mortgage rates very close to the Fed rate and the fact that the system allows you to lever up 4x (20% down) to 99x (1% down) to minimize the opportunity cost of other investments. In general, if you plan to live a house for at least 5 years, you should probably put it on a mortgage.
