There are more consumers buying individual health insurance than ever before and with the individual mandate starting in 2014, those without coverage will have to apply for the first time. So, where do consumers begin?

"For a lot of people, this is a really scary thought," says Brandon Cruz, founder of GoHealthInsurance.com. "For their entire lives they've never had to think about the right health insurance for them, they simply had what their employer provided or went without coverage completely.

Many common mistakes are made that can result in additional costs. Here are five to avoid.
