How do you choose between condos and single-family homes?

Using appreciation as a measure, condominiums in some areas have been as profitable an investment as single-family homes in the past five years. And in some markets, condos appreciated even more, according to some experts.
While single-family homes have been the preferred investment by home buyers, changing demographics are helping make condos more popular, especially among single home buyers, empty nesters and first-time buyers in high-priced markets.
Also, the condominium community has worked hard in the last few years to overcome image problems brought on by homeowners association and developer disputes as well as all too frequent construction-defect litigation.
