Question on Lease Renewal vs Listing

[Tim Cook]

I received indication from current tenants that the they wish to renew the lease but they haven’t signed the renewal document yet. I do not want to miss on new applicants should they not sign it. How should I navigate this? They have been great so it would be great to renew vs going through process of taking new applicants.

Should I still send a notice of non renewal if they do not actually sign an updated lease? Also, do I need to send this notice before putting the home for listing?
