Why We Love St. Augustine

People are drawn to St. Augustine for its rich tapestry of history, culture, and natural beauty. As the oldest continuously inhabited European-established settlement in the United States, St. Augustine exudes a captivating historic charm that resonates throughout its cobblestone streets, centuries-old architecture, and well-preserved landmarks. Visitors are enchanted by sites such as the imposing Castillo de San Marcos, a 17th-century fortress overlooking the Matanzas Bay, and the historic district’s quaint shops and cafes housed in colonial-era buildings. Beyond its historical allure, St. Augustine offers breathtaking beaches, inviting visitors to relax and enjoy the Atlantic Ocean’s scenic beauty. The city’s vibrant arts scene, lively festivals, and events throughout the year celebrate its diverse cultural heritage, further enriching the visitor experience. Whether exploring its storied past, enjoying its coastal splendor, or immersing oneself in its vibrant community life, St. Augustine captivates visitors with its blend of history, culture, and natural charm.

I'm sarah, and I love working with families who love the A1A as much as i do!

A Florida transplant from Atlanta, I’m the licensed Realtor behind Costiero.  With a degree in Interior Design from the University of Georgia and over a decade in marketing and project management, I have a passion for real estate along A1A from Fernandina Beach to Palm Coast.  With education and experience in real estate investment and flipping, my sweet spot is helping families list their piece of paradise for the best market price.  I also love helping new buyers find the perfect vacation property to enjoy along our beautiful stretch of coast.

A Georgia peach at heart, I love an evening at Turner field and have attended the Masters over 25 times (yes, you read that right). My husband and I are bulldogs, but I grew up in a house divided, so I have a soft spot for that yellow jacket.
