NO! This grace period is misunderstood by almost everyone. You have a grace period on the payment only. In other words, if you pay your renewal fee 15 days late, there is no late fee. However, once your license expires, you are out of business. So if you don't pay and/or finish your CE when your license expires, do not sell any real estate or engage in any activities for which you need a license until you pay your license renewal fee and complete your CE.
