Homestead Exemptions to property tax
are usually administered at the
County level -- the specifics of the regulations
can vary however.
This being the case is impossible to give you correct info
regarding your specific situation. However, a quick call to the
County Clerk's Office (in the county in which your home is located)
should provide you with the information you seek.
Also, a phone call to your local
Department Of Motor Vehicles Office
should let you know whether you are even obligated to change the
address on your Driver's License in this situation -- so, perhaps you
should make that call first.
Let me know if you need more input. If not, thanks for the
opportunity to assist you... I would really appreciate your honoring my
efforts by 'pushing the button' and Accepting this answer. Adding
a bonus -- should you wish to do so -- is always warmly welcomed.
