But give one of them $2,000,000 in mortgage debt at 3.0% interest on 3 properties that are rented out, and don't have the other have anything.
In 15 years, those properties will be worth 2-3x as much, and the debt will still be 2,000,000. This is what happened to boomers even though they don't realize it. Its not that houses are some amazing investment, its that no one will give you 7figure loans at 3% interest to buy stocks with money you don't have, but they will do it for a property.
