Hannah Powell TN/VA Broker Associate
Realtor. Negotiator. Chaos coordinator. At Platinum Properties, I help clients unlock more than just doors—I help them find homes that fit real life, not just real estate listings. With over a decade of experience, I’ve learned that honesty (and a little humor) go a long way in this business.
I’ll tell you when it’s a great deal, and I’ll definitely tell you when it’s not. My approach is straightforward, laid-back, and real—because buying or selling a home shouldn’t feel like a high-pressure sales pitch. Whether you’re upsizing, downsizing, or just tired of scrolling Zillow at 2 a.m., I’m here to make the process smoother, smarter, and maybe even a little fun.
Platinum Properties is built on local roots, genuine relationships, and a touch of sarcasm to keep it interesting. Because finding your next home shouldn’t just be successful—it should be a good story to tell later.
