Your credential will expire at the end of your two-year cycle. You are not required to submit anything to the Commission office if you wish to just let your credential expire.
However, you may choose to submit a letter to the Commission office notifying TREAC that you have made a business decision to no longer practice as a real estate appraiser. This could be useful in the prevention of identity theft.
If your license or certification has been expired for more than six months (180 days), you won’t be able to renew that credential. To become a real estate appraiser again, you would have to register as a trainee and meet the current licensure or certification requirements to become a real estate appraiser.
