Is your DSCR ratio greater than 1-meaning are you cash flowing (according to the lender's criteria of mortgage, property taxes and insurance (and HOA) if applicable).

What is on the insurance application that you signed? 

However, it's important to note that this is only applicable within the city limits.

I feel like it would be great to trust a property management company on all of this, but it would be hard not to step in if you could do a better job at screening bad tenants (eg screening HUGE future problems).I initially managed properties myself, but now I delegate that responsibility to my business partner, personal assistant, or a property manager at my brokerage.Most PMs I know will send you an applicant for final approval and you can get on the phone with them and ask them questions

If you receive a loan application that reads: How many flips have you completed in the last xyz years?

Maybe the landlord isn't responding because they don't see the applicant as meeting their criteria. 

Most lenders will use the middle of your three credit scores and if there's more than one applicant, the lender will go with the lower of the two credit scores.

Your accountant will do it for you at tax time if applicable. 

Right now I use an VA from the Philippines to respond to all my leasing questions (from Facebook, email, text, and phone) and help with application screening and it's been working great for over 5 years!

The only issue is with a bit lower rent there's a higher number of applicants that won't qualify but I don't mind the volume to get it filled.
