Accurate Property Tax Calculators

[Joe Wang]

Hi BP Austin, 

OOS investor here. Are there any accurate property tax calculators for Northern Austin properties ? (Round Rock, Cedar Park, Leander, Pflugerville, etc). I see that some of the counties have calculators but not sure how reliable they are. I understand of course, that they are poised to change and property tax assessment is a whole ordeal there, but ideally would like to have good estimates before a purchase, given that they are such a major expense. 

Any recommendations would be great. Cheers
