About Seth Lester

Real estate is about more than buying and selling homes, it's about helping people confidently move into the next chapter of their lives. That's the philosophy behind the Diaz & Lester Team.

As husband-and-wife partners, we understand that every move represents a new beginning. Whether you're purchasing your first home, upgrading for a growing family, downsizing, relocating to Northeast Tennessee, investing in real estate, or selling a property you've loved for years, we're committed to making the experience as smooth, informed, and enjoyable as possible.

Together, we lead NextHome Magnolia Realty, proudly serving buyers and sellers throughout Northeast Tennessee and the Tri-Cities, including Johnson City, Kingsport, Bristol, Jonesborough, Piney Flats, Elizabethton, Gray, Bluff City, and the surrounding communities. Our experience spans residential homes, luxury properties, lakefront homes, historic homes, new construction, land, farms, investment properties, commercial real estate, and relocation services.

O'Mayra Diaz is the CEO and Licensed Broker with NextHome Magnolia Realty and is also a licensed Mortgage Loan Originator with Cardinal Financial. Her background in both real estate and mortgage lending allows clients to better understand financing options, including Conventional, FHA, VA, and USDA loans, while making informed decisions throughout the home buying process. She is passionate about educating clients, solving complex challenges, and creating marketing strategies that help sellers maximize their home's exposure.

Seth Lester brings a calm, dependable approach to every transaction. His background in manufacturing quality control has strengthened his attention to detail, integrity, communication, and commitment to serving others. Clients appreciate his patience, steady guidance, and willingness to go the extra mile, whether helping first-time homebuyers navigate the process or negotiating on behalf of experienced investors.

Together, our strengths complement one another. We believe every client deserves honest advice, responsive communication, skilled negotiation, and a team that genuinely cares about their success. Our business has been built on relationships, referrals, and treating every client like family.

Today's real estate market requires more than placing a sign in the yard. We combine professional photography, strategic pricing, digital advertising, social media marketing, AI-powered marketing strategies, targeted online campaigns, and local market expertise to ensure our listings receive maximum exposure while helping buyers discover the right home at the right time.

Whether you're buying your first home, selling your forever home, searching for acreage, relocating to the Tri-Cities, investing in rental properties, or exploring commercial opportunities, we're here to guide you every step of the way.

At the Diaz & Lester Team, our goal isn't simply to help you close on a property, it's to build a lasting relationship based on trust, integrity, and results. We'd be honored to help you make your next move with confidence.
