> Does this mean we should have borrowed as much as possible to buy a house when rates were low ?
Sort of. You should have borrowed as much as possible up to the level that, under nearly any circumstances, you could have still serviced that debt(i.e. made the payments). Historically, those were really cheap rates to borrow money and we might not see them again for a few years(or a few decades).
Next time we see them again, we will likely be in a hyperinflationary period, I would think. At some point in the future (not brave enough to say when), the Fed will run out of runway, credibility and backbone, and the easy money will never cease until the currency itself dies.
We will see them again after the recession. They will stay low until at least 2030 then we will print ourselves out of low interest rates. Look at an long term interest rate cycle chart.
