New landlord in DC and learning the renal application process

[David Shafa]

Hello all. I'm an amateur landlord in DC. I listed my property on MLS and craigs list just yesterday and so far there has been over 25 people wanting to see it. I wanted to ask how to establish an application process or system for all the interested parties.

Do I take hard paper copies of a rental application at the time of showings?  Where do I get the paper applications from?

Do I request a check for the application fee? or do I use an online system like smartmove.com? If so how much do I ask for this check?  I know bundle packages cost about 40 dollars minimum?

If I have multiple applications, do I process the checks one at a time for those who appear to qualify and go from there (eliminating one by one) or do I process them all and then make a final decision? 

This is overwhelming and any suggestions would be greatly helpful.
