A gut feeling about a prospective tenant

[Gerardo Lewis]

Hi Bp, 

So i have a prospective tenant for my rental and she has been really really interested in the place. Only problem is I haven't verified income yet but I feel like she won't be able to afford the place mainly because of stories she's told me already and that she had to borrow the money (first last and security) just to get in. I still am treating her like everyone as to not discriminate but if i cross the bridge of having to deny her. How do I word that in the letter to her? Is there some trick to the trade I haven't learned yet?
