How to Issue 30 day Eviction Notice After Taking Possession

[Kelsey Vander Meulen]

I just purchased my second investment property- a triplex located in Tucson, Arizona. However, this is the first property I plan to manage myself. 

With that being said, has anyone issued a 30 day eviction notice to their tenant once they take possession of their newly purchased property? We plan to update a couple of the units, and two of the current tenants' leases expire at the end of the month. I've read you must of course give the tenant a notice 30 days prior. I know that you also have to either deliver the notice in person or via certified mail. I'd prefer delivering the notice in person. Has anyone had any issues with this? 

Any recommendations on how to go about doing this would be much appreciated.
