I'll throw in the 180K mortgage interest and the mortgage insurance which I also forgot and wager I still come out ahead. Rent would be somewhere between $750K to $1M over that time and none of it is returned.

Since we control our mortgage, we paid it off early, at around 15-16 year mark (due to my wife making me realize the importance of it). We live rent and mortgage free the rest of our lives thank God. I only wish I'd kept either of our 2 former houses instead of taking better job offers requiring moving ultimately to the bay area where we couldn't afford to buy a home. Texas is nice though!

My Dad always said, buy a house as soon as you can.
