good response to this statement: What standards guide the work of an appraiser? Do they belong to organizations similar to the National Board of Realtors that govern their practice, ethics, etc.? (Be sure to answer this question with respect to rules and regulations in the state you live or plan to live.) : To answer this question as a whole, the appraisals in all states including TX fall under the Uniform Standards of Professional Appraisal Practice (USPAP). This is what ensures all appraisals follow legal and ethical morals when conducting business. As far as specifics of the state of TX, the state of TX regulates the appraisals through what is known as the Texas Appraiser Licensing and Certification Board (TALCB)
