It seems that where some people might become confused is that they compare the cost of paying CASH for a house (i.e., your $300k example) vs. renting. As you point out in this article, mortgage rates have been historically low, and even now (April 2022) are still on the low side. If someone can have the benefits of a house by only placing 20% down -- say, $60k on your hypothetical house -- then they can still invest the other $240k in vehicles that are likely to grow over time.

I agree! When rates are low as they seem still to be. best, Larry
