About Castillo Realty

Your trusted guides in Knoxville real estate

Castillo Realty is a boutique, one-stop shop for all things real estate in Knoxville and the surrounding East Tennessee communities. Founded in 2023, our agency was born out of a desire to offer a more personalized, people-first experience in one of life’s most important and emotional decisions: buying or selling a home.

We believe real estate is about more than contracts and closings: it’s about relationships, trust, and building a future. That’s why we’ve intentionally stayed small, nimble, and rooted in community. With a highly dedicated team, we guide you through every step of the real estate process with expert care, local insight, and complete transparency.
