The "client first" philosophy has always been my approach and it requires me to continually improve my skills and ways of doing business. In addition, I've found that the latest technologies are enabling me to do everything I've always done, only quicker and more efficiently. They've also helped me to extend the range of services I provide to my clients.
That said, in my experience as a real estate professional, I've also found that providing the very best service is essentially. This means keeping myself accessible, being a good listener as well as a good communicator, and responding quickly to your needs.
