Gregg Costin and The Costin Team

Gregg Costin · Realtor, licensed in Florida and Alabama

It started with a vow

Gregg's path into real estate did not start with a passion for houses. It started with a promise made in frustration.

Buying his very first home early in his Air Force career, he was burned by a horrible agent. The experience left a mark deep enough that he vowed to self-educate to the absolute highest level so he would never have to rely on another agent again. Over the next two decades, moving 11 times with the military, he bought and sold homes across the United States and mastered the process from the ground up.

He knows firsthand what a terrible agent feels like. Which means he knows exactly what an exceptional one takes.

From the Air Force to your closing table

Gregg served a full United States Air Force career, starting as a prior-enlisted Staff Sergeant and retiring as a Captain. He flew as a Combat Systems Officer aboard the E-3 AWACS through multiple combat deployments, and finished his career architecting theater-wide air and missile defense plans at CENTCOM.

What that means for you as a client: plans get built before pressure hits, timelines are managed to the day, checklists actually get checked, and nobody panics on the way to closing. Mission planning and transaction management are more alike than you would think.

Rachel Ley is a licensed Realtor and transaction coordinator serving Pensacola and Gulf Breeze buyers, sellers, and investors. In her own words:

"I'm a local mom, entrepreneur, and proud coastal resident who fell head over heels for the emerald waters and sugar-white sand of Pensacola and Gulf Breeze. This stretch of the Florida Panhandle isn't just where I work. It's where I live, raise my family, and call home every single day, and that changes how I show up for the people I serve. Whether you're dreaming of a family home where your kids grow up chasing waves, or you're building lasting wealth through smart property investment, my job is to make that dream feel as real as the salty breeze coming off the Gulf. And I bring a perspective you won't find in just anyone: more than a decade as a technology and AI consultant and business manager, plus years serving families through the deeply personal journey of childbirth education and doula support. That rare combination is why I go above and beyond for every client: genuine empathy for what this moment means to your family, sharp analytical thinking when the numbers and negotiations matter, and meticulous organization so no detail ever slips. Buying or selling a home is one of the biggest moments of your life. You deserve someone who truly understands that and guides you through every step with confidence and care. My goal is simple: to help you find your own little slice of paradise here on the Emerald Coast."
