How much info do you give when you deny an application?

[Kevin S.]

Hey BP,

Looking for recommendations on how I handle this, my first time going through the renter application process. I've received my first application, haven't done a background check yet because I'm already leaning toward denying the applicant. She was nice when I gave her the tour, however there was a very strong smell of smoke. This is a non-smoking property and she marked non-smoker on her application, and I'm not sure if the smell is from her smoking or from her workplace, all I know is I do not want my property to smell like a smoker has been living there. Would you just send an email stating you have chosen not to accept her application or something different? This is so far the only application I've received, and other than the smell of smoke her application meets all the general requirements so far (haven't had her pay for a background check yet as I'd prefer to reject her before she has to pay for it).
