You do have to take into account the time value of money with the mortgage payments still, because $1 today is worth much more than $1 30 years from now. It's the difference between nominal dollars and real dollars.
Conversely, even though rent goes up in nominal dollars, it stays the same in real dollars (or even goes down as a house becomes less marketable over time).
