Is your primary home a liability or an asset?

According to Rich Dad, Poor Dad author Robert Kiyosaki, a primary home is categorized as a liability because of the debt obligation that you have to pay down. However, after the home is fully paid off or has built enough equity, it becomes an asset due to the appreciation. For some people, their primary home is the biggest asset that they’ve accumulated in their lifetime, other than stock options or their business. For me, primary homes are an asset, not a liability.
