The traditional 30-year fixed rate e-loan will give you the peace of mind of knowing that you're not at the whim of the finance markets. However, if interest rates drop it will cost you thousands in charges to refinance to a lower rate. Also, if your financial or credit situation has changed you may no longer qualify at the best rates.

You should ask yourself if you truly need the product. Can you manage without? While companies might make it easy for you, they're not your friends. They're in business to make cash. They also make it on things like fees and insurance. You need to focus on the total cost, and watch your personal finances. Too many people are skating on thin ice for too long.
