Okay, let’s tackle this. So John Tsern has experience as a real estate owner and has skills like negotiation, business development, and strategic planning. These are valuable in the real estate industry. Considering his experience as a business owner and his skills, he might charge a premium rate. However, without specific data on real estate professionals in Newport Beach, CA, it’s difficult to estimate an exact rate. Real estate agents and brokers in the area might charge around $100-$250 per hour, depending on their experience and skills. Since John has more experience in business development and strategic planning, he might be able to charge a higher rate. Let’s assume an average rate for a real estate professional in the area, which is around $125 per hour. However, considering his expertise, I would estimate his rate to be around $150 per hour.
