Is there a good resource/service for collecting property tax rates and related info of specifc municipalities?
Basically the title, but to expand, I'm looking for some bulk data service or API that can be used to collect this information efficiently.

An example would be the Seattle metro area and collecting property tax rates from all of the cities presiding within that range; and really, for the amount I'm trying to collect it'd be more than one metro area - so speeding it up would be greatly valuable (and to know of something like this could also be useful for future applications).

Anyway, I appreciate all recommendations! Thank you.
