This is your opportunity to show your personality. Do not ramble, but rather provide a succinct explanation of who you are as a person, what you like to do, and THEN transition that into real estate. For example you might be a very outgoing person who enjoys staying busy and doing a lot outside of school. Talk about this and how it relates to involvement with the program. Maybe you have done multiple case competitions, traveled, taken the REIT course (shameless plug), or have a position in Real Estate Club.
