Answered this on your original thread...
Personal property tax is most often associated with a car tax that's paid every year in addition to the registration fee. The personal property tax is based on the value of the car.
For instance: In SC you pay a registration fee of about $24 PLUS a personla property (car) tax of 10.5% of the current market value of your car. These both must be paid before you get your license plate renewal and new registration. (Just one example...my mom is constantly upset over the amount of her car tax!)
FL does not have car tax. We pay a registration fee only, based on the size (weight) of the car. DH pays about $45 on his Honda Civic and I pay about $65 on my minivan, and both of those include some money for special plates. (In SC I'd pay about $1700 tax!! Quite a savings!)
Since you're not familiar with it, I'm going to assume your state doesn't have personal property tax, so this probably won't be a PRO or CON for your whether to move list.
I know VA (where we currently live) is phasing theirs out, although it is bankrupting the state (along with other things that aren't helping...)
