When buying life insurance you want to consider your goal for your policy, what do you want your life insurance to accomplish?
Then consider what you can afford, how much you need, how long you need life insurance, and what type of life insurance is right for you.
First consider the type of life insurance - Term or Permanent. Term life insurance costs a lot less and provides more life insurance for your money. It lasts a specific period of time, up to 30 years, or until you reach age 65 or 70. Whereas, permanent life insurance is lifetime coverage and may build up some cash value inside the policy over time.
