Do you provide applications to everyone that looks at rental?

[Mary Munoz]

I'm a new landlord and have some renters coming to look at the property. I scheduled a showing for the weekend but just scheduled another for tonight. If the group tonight is interested, do I give them an application and honor the showing I already scheduled for the weekend? I guess I'm just a little confused on (1) when to give an application, and (2) how to decide who gets to rent it when there are multiple interested parties. Any advice is appreciated!
