You were one of the smart, fortunate ones. Everyone I knew, that was living in a rental, I urged to buy. A few paid attention and are smiling today. Those opportunities don't come around very often. However, it's still possible it will happen again in the not to distant future if we don't see a real improvement in the economy.
As long as the tax laws don't get changed by some exuberant legislatures again, it's also the best way to build a tax free nest egg. In '97 they changed the Cap Gains laws on primary residences. You can make a $250k profit and not owe taxes. I bought a second house during the ugly days at a very reasonable price in a warmer climate (not warm, but better). I can sell my house here with no taxes, move in there and live for two years (required to establish primary residence) and sell that tax free. Then move somewhere with a better climate.
