Usually term insurance plans can be cheaper, but they are term which is they usually only last 20 to 30 years. They are good because it is more affordable, but they are bad because after the term is up, well, you are without life insurance again and it will be even harder for you to get it at a good price at that point.
I got a life insurance plan about 5 years back and I had already lots of health issues. Nothing that was considered deadly. After speaking to the agent who was helping me, she got me a whole life plan. Mind you, I was only able to get a 25,000 plan, as that is all we could afford and it was not cheap. She said they labeled me a 13. I asked what that meant, and she said it means you are at the highest risk. My husband said what do they know about my health that we don't know??Lol!!!
Anyone who is dealing with a chronic illness is going to have a hard time getting very affordable life insurance unfortunately. It is not fair at all. But you know how the insurance companies are, they don't want any liabilities as horrible as that sounds.
