[Landlord-AZ-US] Question: Procedure for Lease Nonrenewal

I have a question about my current tenant. They are inherited tenants from the previous owner. There is quite a bit of damage on the unit before I bought the property. We plan not to renew their lease because we would like to renovate their unit after the lease expires. I found this page https://www.azleg.gov/ars/33/02143.htm which states that I have to give them a reason for nonrenewal and there are different requirements on the notice for different reasons. My question is

· For the reason part, how much detail do I have to put in. Can I say: Renovation of the unit

· How many days of notice do I have to give them?

· If it is 30 days, I understand that it is hard to find a rental right now, can I offer them 60 instead of 30 days?

Any help is appreciated. Thank you very much!
