Potential Tenant Rejection

[Cindi Freeman]

By law do I need to let each tenant know I am not moving forward with them? I am in Idaho and new to being a landlord again.  I am using Cozy as my application process but they do not have a reject button. Any other systems you would recommend or do you reach out to them directly saying "We're sorry but we've rejected your application".  Or is that even necessary?

Thanks in advance for your help!
