Is there rent control in Mesa Arizona?

[Robert Vorhies]

I am look to purchase a duplex in the city of Mesa Arizona and the currently tenants are only paying $500 and $600 per month. The going rate for the area is about $1100-$1300 per month.

when I purchase this property can I give a notice of increase of rent after 30 days or does the city of Mesa have a some form of rent control? Or is that just bad form to double the tenants rent?

thank you in advance for your help.
