I don't think for a minute that owning a home costs less month-to-month over renting - with maintenance and upkeep, repairs and new appliances periodically, it's probably a break-even at best. But, at the end of it in 20 or 30 years I can sell the house and have that money (to buy a smaller house, or move into something senior-citizen appropriate, or a condo or whatever). With renting, that's not the case.
It also helps that I live in the Midwest, where property prices are not insane. I just sold my first house (made almost $30k over what I paid 18 years ago), and now I'm buying a 5-bedroom, 3k sq ft house in a nice neighborhood... for $230k.
Is it for everyone? No. But there's no way I'd rent, at least not at this stage of life.
