Rental Applicant Follow Up

[Marcus House]

I am trying to improve on my process of renting properties.  I have already picked up a few pointers on this site that I had not thought of previously.

As a landlord or property manager, after someone view your property, they say their are interested and you give them an application do you ever follow up?  I say this in the context of the fact that when someone comes to look at your property most people never walks around with proof of income in their possession (as an example) so they don't have everything needed to submit a complete application.  This typically translates into people submitting a partial application to get the process started or nothing at all until they have everything.  Either way, as part of your process do you ever do a follow up call (or email/text) to people that fall into one of these groups or do never follow up and focus on setting up showings and processing complete application packages?
