How we work it is if an applicant is accepted, they have to pay a "holding fee".

Successful application in real life requires in depth education. 

Then you need to contact your lender (if applicable) and see if/how you can make that happen.

Traditional and Section 8 applicants can all apply for any rental.I recommend asking market rent for unit #3, then vet your applicants properly. 

I have a well qualified applicant (2 friends whom lived together before), but one of them let me know they smoke.
