Find something that makes you seem relatable on a personal level to the person touring. This makes this big decision feel more like a recommendation from a friend, than it does a "sale" from an agent.
Do you also live in the area and can relate to a shared interest in food/beer/fun? I have one community that is mostly down-sizers, so for this one, I tell them- I understand this is a big decision! My parents went through the same process and are so happy to have single-floor living, or "oh yes, my mom doesn't miss going down all of the steps to do laundry every day, etc". In my young professional community that I manage, I connect to their lifestyle and tout the great bars and restaurants near by, etc. My friends and I love this location, so many great happy hour options etc.
Follow up casually, just so they know you're there for any questions. Let them know you aren't rushing them and you want them to be happy and confident in their decision. This works very well for me and my staff!
Be kind, show up early and smile! Best of luck to you
