I was half expecting/hoping this would talk about the opportunity cost of owning a home. More precisely, owning a primary residence.

There are quite a few studies about this, but it is something which is not discussed broadly enough. But there is a inverse relationship between home ownership and income.

Because for most regions across the globe, once someone buys a home, they start looking for work that's in geographic proximity to their primary residence. And in most parts of the world, incomes generally tend to stagnate since higher paying jobs are almost always away from where people live.

Now a lot of people believe that they will pick the higher income, but the amount of logistics which goes into thinking about selling your home or renting it even often dissuades people from trying to look for a job which pays significantly more.

Interestingly, some multinational companies that I know of facilitate the entire transaction for their executives and senior managers when they need to move cities or countries because of this effect.

Owning a home for the purpose of investment and not living is a different matter, and the same effect isn't seen there.
