What Should I ask for prior to showing a rental property

[Justin Kline]

I've been getting stood up left and right from prospective tenants even after confirming the appointment. Should I require a filled out application, credit report, references, or all 3 prior to showing the property to weed out all of these seemingly un motivated uninterested leads? Are there any other recommendations so I stop wasting so much time waiting for no one to show up?
