About Jill Mangum, Broker/Owner – 

St. Augustine Real Estate Broker | Guiding you through the buying and selling of island and inland homes, condos, and commercial properties with trusted local expertise.

As a proud North Florida native and longtime St. Augustine Beach resident, I bring local insight and years of experience to every transaction. I help clients buy and sell homes, condos, and commercial properties throughout St. Augustine and the surrounding areas.

I earned a Bachelor of Arts degree in Business Administration from Flagler College. Before entering real estate, I gained experience in new home construction and out-of-home media sales, helping corporate clients across the United States secure premium billboard and advertising locations. These roles strengthened my skills in marketing, negotiation, and identifying prime locations — all of which have seamlessly transitioned into my real estate career. Today, I combine that expertise with my passion for helping clients navigate the buying and selling of homes, condos, and commercial properties throughout St. Augustine.

I live on beautiful Anastasia Island with my husband, and we truly enjoy the coastal lifestyle that makes St. Augustine so special. My goal is to provide each client with superior service, strong ethics, and personalized attention — because honesty and integrity are at the heart of every great real estate relationship.

Whether you’re dreaming of a vacation getaway, your forever home, or an investment opportunity, I’m here to help you navigate the St. Augustine real estate market with confidence and care.
