Showing prospective tenants the property remotely

[Neil Hunter]

My current tenant is about to move out, and I'm thinking about ways to make the transition to find the next tenant smoother. Some questions:

1. One thought I had was to install a keypad lock. I'm a little confused on which one I would get. Since my tenant will be responsible for their own internet service, I can't rely on a WiFi-enabled one, like August. Is there such a keypad where I can generate temporary passcodes *without* internet access? (see my use case below). 

2. Anyone ever schedule a "remote viewing"? My idea is to have them book a time when we're both free, and I would give him a temporary code to a keypad lock. Then we would FaceTime or some other means, and I could remotely meet him and answer his questions while he is free to wander about the house by himself. Is this a bad idea?

Any tips much appreciated.
