Screening / Pre-Qualification Questions

[Troy D.]

Just wanted to get some feedback on some questions regarding screening.  I appreciate any thoughts you may have. 

When a prospective new tenant calls about a property I'm assuming you do a screening interview over the phone.  If the interview goes well do you send a pre-qualification form that has to be filled out before showing a unit after the phone screen?

Do you send the minimum criteria required to rent from you along with the pre-qualification form or do you wait to give that to the prospect at an open house once they fill out an application?

What do you use as a gross monthly income requirement 3x or 4x the rental amount?  Do you allow married couples combined income for this criteria?

What do you use as a minimum credit score that's required to rent from you?
