You buy a house. It grows in value. You then use that value as a down payment on a bigger better house that you now pay as much as rent for monthly. And you multiplied your wealth and have a wonderful place to live.
When you retire you sell that house, buy your kids a down payment, and yourself a place in a low cost of living area. And now you enjoy the fruits of your life's labor till you die.
But this all relies on population growth and a lack of better housing options. A. K. A. House prices generally always go up.
