It actually is. You just can't be over-leveraged. The bank will give you waaayy more money than should ever responsibly be taken. Combined with emergency savings, you are quite safe as a homeowner.
Yes if you stay within your limits. But if you start loading up on debt because of low interest then things can go bad very quickly. So the advice go stop saving is bad.
No. They learned that buying a house with ridiculous terms and unlimited downside is not as safe as they were deluded to believe. Even in 2008, most people paid their mortgages, and were fine, housing wise.
I agree that lotteries are close to one side of the risk scale but real estate is closer to the middle than to the other extreme. The other extreme is U.S. treasuries. The last recession was a great illustration of the risk inherent in real estate.
And the US treasuries won't even keep up with inflation. If you invested yesterday you'd need to lock in for at least 20 years before you got even 1% return.
