Get deposit with application?

[Jimmy S.]

When a potential tenant turns in a application how much of a deposit should I get? If accepted it will be applied to first month rent or how does everyone else do it?  I also don't charge a fee which I tend to believe I should.

I never use to get a deposit but I am finding that I am only hurting myself by allowing that tenant to continue to shop for homes while there application is under review.

Thanks
