"I have been successful in Real Estate for many years, working on a highly commissioned basis. Of course, my first few years were difficult but I managed to press through those challenging years. I am a solid salesperson and well sought out because of my positive reputation in the industry. This amounts to many referrals for me as well."
A successful Real Estate professional must be confident in their sales skills since most roles are 100% commission based. Assure the interviewer that you are capable of earning a great living based solely on your sales abilities.
"I have a Bachelors Degree in Marketing which has helped me immensely when it comes to promoting my Real Estate business. Because of this education I have a strong understanding of multiple marketing and advertising techniques including social media and online marketing."
Although a post-secondary education is not always a requirement to work in Real Estate, it can certainly be an asset. If you have obtained a degree, diploma, or other form of post-secondary education discuss this briefly with the interviewer.
