Yes, good to do the calculation properly before making the decision if its motivated primarily by finances; sometimes the outcome can be surprising. Ironically speaking specifically about Portland, you'll pay _less_ in taxes moving to e.g. Washington schools in addition to getting better schools. But I think this is likely a special case.

Yes, I definitely agree, YMMV, tax situations and school district quality vary greatly depending on specifics.
