The Real Cost of Living in Hammond / Warrenton, Oregon

The Headline Price -- and a Real, Disclosed Spread

Different sources report meaningfully different numbers for this small a market. For the Hammond ZIP code (97121) specifically, one aggregator (Realtytrac) put the August 2026 median list price at $545,000, with a separate median sold price closer to $474,916 and a price range spanning roughly $176,900 to $669,000; Coldwell Banker's own listing-site estimate put a median home price near $509,750, with 22 total properties sold there in the trailing 12 months -- a genuinely small transaction count that leaves any single median vulnerable to being moved by one or two atypical sales. For Warrenton citywide (which now includes Hammond), Zillow's smoothed home-value estimate was $509,750 as of mid-2026, down about 1.7% year-over-year, while Redfin's closed-sale median was reported at $430,000 in November 2025 (down roughly 9.4% year-over-year) and a July 2026 Movoto listing-price snapshot cited a $589,000 median asking price. None of these numbers is fabricated, and none should be read as a single settled "the market" figure -- they're different measurements (list price, sold price, smoothed valuation) taken at different points across roughly a year in a market too small and thinly traded to produce one stable number.

The practical takeaway: treat any single quoted Hammond or Warrenton median as a rough midpoint of a genuinely wide range, and get a current comparative market analysis from a local agent pulling actual closed comps for the specific style, lot, and proximity to the river mouth or state park you're looking at -- location within Hammond varies a lot, from marina-adjacent lots to homes closer to the state park boundary.

Property Tax: Oregon's Measure 50 System, and What It Means Here

Oregon runs a property tax system that surprises buyers moving from almost anywhere else. Under Measure 50 (1997), a property's Maximum Assessed Value (MAV) can grow no more than 3% per year under state law (ORS 308.156), regardless of how much its actual market value moves -- and the taxable Assessed Value used to calculate the bill is legally the lesser of MAV or the county's Real Market Value (RMV) estimate. Critically, and unlike California's Proposition 13, a sale generally does not reset a property's MAV to the new purchase price; a buyer can inherit a long-held owner's comparatively low assessed value, at least initially, with real exceptions for new construction, additions, and other statutory "exception events." Layered on top, Measure 5 (1990) caps the combined permanent tax rate at $10 per $1,000 of real market value for general government and $5 per $1,000 for schools, with a "compression" mechanism that proportionally reduces bills that would otherwise exceed those constitutional ceilings.

For the specific ZIP-level effective rate here: one property-data aggregator (Ownwell, via search synthesis -- its own page could not be directly refetched this session because the domain was blocked by this session's network egress policy) puts Warrenton's median effective property tax rate around 0.60% of assessed value, with a median annual tax bill near $2,714 against a median home value around $466,612. Applying that rate directly and for illustration only: a $450,000 assessed home would carry a tax bill of roughly $2,700/year; a $550,000 home, roughly $3,300/year. These are rate-times-value estimates, not actual county tax-card figures, and the real combined rate for a specific Hammond parcel depends on which exact taxing code area it falls in (city, county, school district, port district, and any fire or special district) -- Clatsop County's own Assessment and Taxation office, not this page, has the authoritative figure for a specific address.

No State Sales Tax, But a Real Income Tax -- Not a Simple Trade

Oregon is one of a handful of states with no state or local sales tax of any kind, on anything -- a genuine, ongoing saving on every taxable purchase made after closing, from furniture to building materials for a renovation. That's frequently the headline a relocation guide leads with, but it's only half the picture: Oregon also levies a graduated personal income tax running from 4.75% on the first roughly $4,050 of single-filer income up to 9.9% on income above $125,000 (married-filing-jointly brackets are roughly double those thresholds), among the higher top marginal income tax rates in the country. Whether that trade nets out favorably for a specific household depends entirely on that household's income level and spending pattern -- this page isn't going to model a single generic "Oregon is cheaper/more expensive" answer, because the honest answer is that it depends on the buyer.

Insurance: A River-Mouth Flood and Tsunami Profile, Plus Earthquake as a Separate Choice

Hammond's location matters directly for insurance. It sits on Clatsop Spit at the literal mouth of the Columbia River, closer to open water on multiple sides than almost any other community on the Oregon coast -- and it's specifically named in Oregon's own hazard planning: the state geological survey (DOGAMI)'s Open-File Report O-16-08, a local tsunami evacuation analysis, is titled for "Warrenton and Clatsop Spit" by name. That report models evacuation for a worst-case Cascadia Subduction Zone earthquake scenario (a projected magnitude-9.1 event, termed XXL1 in the county's own hazard planning documents), and Clatsop County's land use code separately prohibits new critical facilities inside the mapped tsunami inundation zone. None of that means every Hammond property is in the inundation zone -- exact boundaries vary block by block on the spit -- but it does mean a specific parcel's tsunami-zone status and FEMA flood-zone designation are worth confirming before budgeting a purchase here, more so than in many other coastal towns this site covers.

On ordinary flood insurance: Oregon's typical NFIP premiums are commonly cited in the roughly $450-$980/year range depending on flood zone, elevation, and distance to water, with one nearby same-county reference point (Seaside, also in Clatsop County) cited around $777/year -- again, a directional range, not a Hammond-specific quote. On homeowners insurance generally, Oregon's statewide average runs meaningfully below the national average -- one source puts it around $1,124/year (about two-thirds below the roughly $3,467 national average cited by the same source), while another source-set traces Oregon's average from about $583/year in 2018 up past $886/year by 2023, a genuine and disclosed spread across sources rather than one settled figure; coastal-adjacent areas like Hammond typically price above the pure statewide average. Separately and importantly: a standard Oregon homeowners policy generally does include windstorm coverage (unlike hurricane-belt states with separate wind pools) but excludes earthquake damage entirely -- earthquake coverage is a distinct, optional policy that only about one in five Oregon homeowners carries, typically with a high deductible in the 10%-15% range of the coverage amount. Given Hammond's direct exposure to the offshore Cascadia Subduction Zone, that's a real, deliberate decision to make with a licensed Oregon broker, not a box to skip.

Short-Term Rentals: A Split System, Not a Simple Cap

The City of Warrenton -- which governs Hammond -- draws a sharp legal line that matters directly to any buyer weighing rental income. "Homestay Lodging" covers an owner-occupied single-family home renting up to five bedrooms (including bedrooms in an accessory dwelling); it's permitted, upon approval, in certain residential zones, requires a non-refundable $150 permit application fee, and the rented space may not include a kitchen. A "vacation rental" -- a non-owner-occupied home rented for stays under 30 days -- is a legally distinct category that Warrenton's code prohibits in residential zones outright; it's only permitted, upon approval, in commercial zones that already allow hotels and motels. In practical terms: a buyer planning to own a Hammond house and rent it out short-term without living there should assume that's not permitted on a typical residential-zoned lot, and should confirm the specific parcel's zoning designation before counting on that income stream at all. This is a meaningfully more restrictive framework than some Oregon coast towns (Astoria, for comparison, permits a capped number of commercial-zone vacation rental licenses citywide, covered on that market's own pages) -- Warrenton's residential-zone door is effectively closed to non-owner-occupied short-term rental.

Putting the Real Number Together

For a representative $450,000-$550,000 Hammond-area purchase, a realistic annual recurring-cost floor looks roughly like: $2,700-$3,300 in property tax at the reported ~0.60% Warrenton effective rate (subject to the specific parcel's actual code-area rate); a homeowners policy likely in the low-to-mid four figures depending on the property's exact flood-zone and tsunami-inundation-zone status, plus a separate flood policy and, if chosen, a separate earthquake policy given the Cascadia exposure; no state sales tax on anything purchased after closing, offset by Oregon's graduated income tax if relocating from a no-income-tax state; and a hard legal wall against non-owner-occupied short-term rental income on a typical residential lot. None of these figures substitutes for an actual Clatsop County tax-card pull, actual insurance quotes with an address-specific flood-zone and tsunami-zone determination, and an actual comparative market analysis for a specific property -- but together they give a far more honest starting budget than a bare purchase-price headline alone.
