Can a life insurance license help you get an appraiser license?

The licenses are regulated by the state where you live and any states where you desire to work under the license. A life insurance sales license will have nothing to do with a license to be an appraiser. They are probably controlled by to difference agencies if you are talking about a property appraiser. If you are talking about an insurance adjuster rather than appraiser then they would both be handled by the Insurance Department.
