There isn't a real difference between life annuity and an insurance annuity. Both are a form of life insurance and deal with the same issues. I would go with either one.

A period certain annuity guarantees payments for a specific period, such as 10 or 20 years, regardless of the annuitant's lifespan. A life annuity provides payments for the lifetime of the annuitant, ensuring income for as long as they live but ceasing upon their death.

Annuity Life is a contract of insurance between you the buyer and the seller. Variable Annuity Life is a company that covers retirement groups for schools, colleges and Health care.

Yes an annuity is a life insurance product. Its kind of like the opposite of life insurance.

If you are living alone, a single life annuity would be the best. However, if you have a family or a wife/husband, you may want to consider multiple life annuity.
