Assessing tax rates in PA

[Shahadat Reza]

I am trying to analyze deals using bigger pockets calculator. Looking into properties in Delaware county. What is a good way to get an approximately accurate property tax and insurance rates in PA? I have heard that Zillow or MLS are not very reliable sources. I have tried searching the county websites but each township/borrough/school district seems to have their own rates and most of them are not even accessible online. So is the easiest way to just call each and every township asking about their millage rates? That seems very time consuming for just an initial analysis. Or are there any other ways?

Thanks,
