Any nationwide system to check actual property tax?

[Sarp Ka]

Hello there,

I'm an out-of-state investor. I found an issue regarding to property taxes. They are never accurate on Zillow etc. I've recently been browsing Miami area, and I found that most likely you'd be paying property tax around 1.9-2.2% depending on the county. According to Zillow it's much less than that. Not knowing those areas well is a problem, asking around or checking individual county's website is often slow too.

I found that out by checking local county's tax calculator + found properties in the same area that's sold for similar pricing back in 2019 and how much they are taxed in 2020.

I had the opposite for Las Vegas, where the numbers were higher than the truth.

When you google, "property taxes in xyz" they only mention what an average property tax is in a given area, often that percentage has nothing to do with booming markets and does not indicate anything near what you'd be paying.

Anyway, just curious if there's any service where I can just put the zip code and get the real property tax amount/percentage that I would be paying if I purchase a house in that area?

Thanks
