So, you're buying term life insurance and you're going with the company that gave you the "best" quote. Just keep in mind that you may not qualify for that rate due to cholesterol, pre-existing conditions, family health history, or your build (that's a nice way of saying that you're overweight....or just undertall.)
First of all deal with a broker (like me) who has access to different companies and can give you guidance depending on any of the problems/conditions listed above. Obviously any pre-existing conditions and medications will affect the final cost and may require a little shopping that you really can't do without the aid of an insurance broker. And, for goodness sake use the service because it doesn't cost you a dime since insurance is a regulated product and going direct to a company when available provides ABSOLUTELY NO BENEFIT to you. In fact, it lessens the quality of the recommended product and lowers the quality of service.
But, don't assume that you'll qualify for the "best" rate just because you have no adverse health history, are of average height and weight, and take no maintenance medications. Items that commonly knock an applicant from a top rate class (which could add 10-40% cost to the policy) are cholesterol (both your total cholesterol which usually needs to be under 220 AND your "ratio" which usually needs to be under 5.0) and family health history -- having a parent that deceased prior to age 60/65 due to cancer or heart disease will in most cases immediately knock you out of the top class. But, each carrier is a little different and by letting me do the homework for you, I might be able to find you a carrier that you'd otherwise not find on your own -- because this carrier's "best" class you might qualify for where the competitor's "best" class, which is a lower premium, is unattainable. Use your broker and save on the rate.
You'll also gain yourself a resource to ask many questions about different financial services products in the future. This is something you will not gain using the Matrix Directs and the SmartQuote companies. Besides, even though they are bigger companies, their rates for the same products are identical to mine and they carry anywhere from 8-15 companies where we have in excess of 150. So, I beat them every time!
