The Texas Real Estate Commission (TREC) does not specify an exact response time for communications between realtors and their clients. However, it is generally expected that realtors maintain timely and effective communication. A reasonable response time is typically within 24 hours, though many realtors strive to respond much sooner, especially in competitive markets. The expectation for timely communication can also depend on the urgency of the situation and the norms agreed upon between the realtor and the client.For specific guidance, realtors should refer to TREC's rules and the Code of Ethics provided by the National Association of Realtors (NAR), which emphasize professionalism and prompt communication.
