For security we use Showingtime.com to schedule all showings. This is a call center most Realtors use and keeps you from having to field lots of calls 24/7. The service is also used for your security to confirm the showing agent is licensed in TN, also the service solicits feedback from the showing agent. You will receive log in information after your listing goes live. You can confirm showing by email, text of phone call.
If you ever show your home yourself, please take all appropriate security precautions.
