To clarify, the amounts shown in the article only apply to that year - and they are estimates. They are not cumulative. So, if I now pay $2,000 in property tax (and I have a home that has a median value for South Whidbey), in 2018 I'd be paying $2,280, in 2019 I'd pay $2,320, etc. Also, this only applies to the education tax collected by the state, not to an amounts the local school districts might get through levies, etc.
