If you don't own a home, you pay rent, and rent increases over time. Even if you never made a dime on selling the home years later, the difference between years of rent vs. the total of your mortgage may still come out ahead. Or, keep the house, and live the rest of your live only having to pay property taxes and utilities. Either way, inflation goes up, rents go up, mortgages go down.
I'm not sure that invalidates the larger points within the article. I just worry about the perspective of treating a home purely as an investment when their primary benefit is to be a roof over your head.
