You want a good anecdotal reason? Here...
I bought me first home in 1994 at age 22. It was a modest 3-bedroom house with a basement and a decent-sized fenced yard in a nice neighborhood. My monthly mortgage payment was barely more than what monthly rent on a 1-2 bedroom apartment would be... yet I was in a house, and it was mine.
While owning the home it appreciated in value, and I was also able to get Tax deductions (itemized write-offs) on the interest and property taxes, which is always nice. You can't do that when you rent an apartment.
And here's the kicker... less than 10 years later I sold the house for $30,000 more than I paid for it (and my mortgage balance was about $30,000 less as well). So I walked away with $60,000 in my pocket, which I decided to use to put down on the huge home I own today. I then realized that's how it works for a lot of people. That's how you end up in nice, huge palatial houses. You simply "trade up" every 10-15 years (if you choose). Or I could have chosen to buy a similar house and kept a nice $60k windfall. Or stayed there another 10-20 years and watch my equity continue to rise.
In any case, were I renting those 10 years I would have had no write-offs during the time and when I decided to leave I'd have NOTHING to show for it $$ wise.
So, I think the question SHOULD be, if you had the choice... "Why would you ever rent??"
