Owning a home means that you have paid money to purchase it (typically your down payment and mortgage payments). It therefore has a value that you can get out of your home when you sell it.
Traditional homes have the added value of the land that they are built, which typically increases with time. The land value can become 50% or more of the sale value of the home.
If making the mortgage payments are maintained, eventually the home will be owned outright and the cost of operating the home will reduce by the mortgage payment amount and the full value of the home will be realized when the home is sold.
