Oregon's real, progressive income tax -- topping out at 9.9%

Oregon's income tax is genuinely NOT zero: it runs progressive with a real, current top marginal rate of 9.9%, applying statewide including in Astoria -- though Oregon does not tax Social Security income.

Oregon's genuine zero sales tax

Oregon is genuinely one of only five US states with NO sales tax whatsoever -- a real, statewide fact applying identically in Astoria.

Clatsop County's disclosed property tax spread

Clatsop County's effective property tax rate is cited at 0.69% by property-tax aggregators, against a separate 0.82% CalcHubb citation -- this record uses 0.69% as its primary figure, reflecting Oregon's Measure 50 assessed-value-growth cap (generally 3%/year) interacting with local levies.

Insurance: a real, substantial tsunami-zone exposure standard policies do not cover

Standard homeowners insurance does NOT cover tsunami, flood, or earthquake damage. Astoria's downtown core, port, and main highway all lie within a mapped Cascadia tsunami inundation zone, with real, additional earthquake and landslide risk layered on top. Confirm any specific address's zone status and current insurance options directly -- elevation matters directly here, and this record's best-areas topic covers Astoria's real hillside-versus-bayfront geography.
