According to the National Association of Home Builders, the average price for a new home in 1980 was $76,400. In 2005, the average was $295,100.

That's incredible! $218,700 in caaash ...
Before you get too excited thinking about investing in real estate and flipping houses, ponder this: Over a 25-year period, that $218,700 gain comes out to a 5.6% annualized return.

Think about that. If your stock investments had grown at just 5.6% annually over the past 25 years, you'd be kicking yourself. And with good reason -- during that time, the S&P 500 earned 10.3% annually -- almost double the average gains in housing. Hershey (NYSE:HSY) would have doubled the average house's return (13%). Johnson & Johnson (NYSE:JNJ) (18%) and General Electric (NYSE:GE) (19%) would have more than tripled it. Even Eastman Kodak (NYSE:EK), the very picture of long-haul underperformance, churned out a nearly 7% annualized gain from 1980 to 2005.

Treat investing like you treat homeownership
During the past eight years, home prices have grown at a much faster clip, so some of you are probably accusing us of cheating. We aren't.

Instead, we're taking a long-term view -- because that's the only view that can make you super-rich.

What's a mere million
Consider that cocktail-party story about Sal from Asbury Park who made a million a few years ago flipping condos in Miami. It's a great story, and we'll go ahead and bet that bits and pieces of it are true. In fact, it might all be true.

But for every Sal from Asbury Park, there was a Jimmy from Hackensack who got in over his head and lost everything. Yeah, that happened too. That's why the subprime lending market is collapsing around HSBC (NYSE:HBC), Washington Mutual (NYSE:WM), and New Century Financial (NYSE:NEW), among others.

And even if Sal did make a million in 2003, is he set for life? Certainly not. In order to make that nest egg last, Sal can only withdraw about $40,000 per year. Our guess is that Sal wants to live better than that. So he probably kept flipping houses. Flipping and flipping until the Miami condo market came down around him. Or, if he's still holding properties, the real estate boom cycle has ended, and Sal will be lucky to eke out 5% returns over the next decade or more -- all the while servicing the debt he needed to buy those condos in the first place.

A cautionary tale
Of course, Sal's a figment of our imagination, but we invented him to make a point. One great year will not set you up for life. Even a short-lived real estate boom won't make that happen. To set yourself up for life, you need decades of good years. And the stock market is the wealth-building enterprise that has demonstrated the ability to return 10% per year for decades. In other words, buy a house for the comfort, but buy stocks for the profits.

Don't get us wrong. That absolutely does not mean there won't be down years in the stock market. But history shows that the good outweighs the bad, and you can do better investing in stocks than in any other asset class.

Make your fortune in the market
Pick up any newspaper, and you'll be faced with pundits who think now is an uncertain time to start trying to make your fortune in the market. But they're taking the short-term view. You can do better by taking the long-term view.
