Deny Applicant after Sending Lease Agreement

[Chris Gilliam]

Hey All,

   I have a tenant that is out of state, approved thier application. Sent them the Lease agreement and requested they send the signed lease and security deposit within a week (actual date).  Prior to getting the lease they were "oh we will send the security deposit as soon as they get approved", Once i sent them the lease they are like well i need to wait 3 more weeks before getting that to you. Now i have not received either one of those, how can I move on and deny them without getting sued... Anyone ever had this type of scenario before or any recommendations?

Thanks,

Chris
