Rehabbed my building, ready to rent, will taxes skyrocket?

[Mirzet Mehovic]

Hi, first time poster but skimmed through some of the biggerpockets books, watched the youtube and hopeful for some good learning and sharing here. 

Anyway I have a building that has 4 apartments and a commercial area downstairs and is rehabbed nicely and almost ready to rent. The taxes are currently about $6,000 a year total. I looked at a close by property which is already rented and taxes are $37,000 per year.  They have much more units so I'm not expecting my taxes to go that high but is there a rule for this on how much it would increase? Is this in a town by town basis that I should ask my town hall where my building is? 

Thanks for any info you guys and gals can provide on this.
