I do not know of any Real Estate Agents in Knoxville that specialize in finding rental homes except for dedicated Property Managers (Property Managers in Tennessee must be licensed real estate agents.). You can ask any rental agent to do a search of the MLS for rental properties, but very few properties in Knoxville are listed in this manner. The majority of rental homes (this excludes rental apartments) in Knoxville are handled by one of three dedicated property management companies Gables & Gates Property Management, LLC, Wallace & Wallace Property Management and Realty Management or through owners directly. I know there are few more small property management companies in Knoxville, but I do not know there names, or have websites. Additionally, you can use Knownews.com, Trulia.com, Zillow.com and Craigslist.org I can only speak for my company, but we will assist you in finding a rental even if we don't manage it. Please call the office at (865) 777-9191 and ask to speak with Caroline.
