Okay, let’s tackle this. So Carmen Romero has 21 years of experience as a real estate broker. This is a long-term career in a competitive industry. In the US, the average hourly rate for a real estate agent can range from $30 to $100 per hour, depending on location, experience, and performance. Visalia, California is a mid-sized city in the Central Valley, which tends to have lower real estate rates compared to major cities like Los Angeles or San Francisco. Given Carmen's extensive experience and local presence, I estimate her hourly rate to be around $75, which is on the higher end of the average range for a real estate broker in her location.
