Is Apartments.com and Zillow the best for screening apps

[Cory St. Esprit]

I have a 2BR, 1 Bath apartment listed for rent. I have it listed on Zillow, Apartments, Facebook, and Craigslist. I know Apartments.com and Zillow does tenant screening, but for those on Facebook and Craigslist, what's the best route to get the application filled out and to have the background check done?

Should I route them through Apartments.com? By my understanding, they pay a fee to apartments for the background check and application, right? Would love to hear your tenant screening processes and how that works.
