Ilwaco, WA: An Honest Investment Outlook

What the Price Data Actually Shows -- and Its Limits

Town-level price data for Ilwaco exists across several aggregators, but it disagrees with itself enough that no single figure here should be read as a precise benchmark. Zillow's own home-value index (a smoothed valuation estimate, not a transaction median) put the average Ilwaco home value at $407,333 as of mid-2026, up 3.3% over the prior year. Separately, one aggregator reported a $635,000 median sold price for November 2025, and another put the median at $546,105, up a much more modest 1.1% year-over-year in its own reporting window -- a roughly $230,000 spread between the lowest and highest of these figures within the same general period. A fourth figure, a $799,000 median list price from a Redfin subpage explicitly filtered to a 'cheap homes' category, should not be read as a market-wide figure at all given that filter, and is noted here only to flag it as a data-quality trap rather than a real number to rely on.

The honest read: Ilwaco is a genuinely small, low-transaction-volume market, and Zillow's ZHVI, a median-sale-price figure, and a median-list-price figure are three structurally different metrics measuring different things -- a smoothed model estimate, actual closed transactions, and current asking prices, respectively -- that will not agree with each other even in a well-documented market, let alone a small one. Treat every Ilwaco-specific price figure on this page as directionally useful context, not as a precise, audited index the way a national Case-Shiller or FHFA figure would be for a major metro. This research also flags one demographic figure worth real skepticism rather than face-value acceptance: Ilwaco's reported 2024 median household income (roughly $98,000-$99,500 across two aggregator sources) looks unusually high given the town's fishing-and-tourism economic base, and more plausibly reflects the wide margin of error typical of American Community Survey estimates for a town this small than an accurate current figure -- a buyer should not use it as a reliable underwriting input.

State and Regional Context

This research did not compile a specific multi-year Washington statewide home-price-appreciation percentage this session -- a genuine, disclosed gap, unlike the state-level appreciation data this site has sourced for some other Pacific Northwest markets. What can be stated with more confidence is Washington's tax and levy structure, which shapes appreciation math indirectly: the state's 1% annual property-tax levy-growth cap (described in full on the real-cost page) means a taxing district's total collections grow slowly by law even as individual home values rise, which is a real, structural difference from states without such a cap. Pacific County itself is a rural, lower-density coastal county relative to the Seattle metro and Puget Sound markets that dominate most statewide Washington housing coverage -- meaning statewide Washington figures, even where available, may not translate cleanly to a small Pacific County fishing town, and this page does not assume they do.

Washington's Real Estate Excise Tax (REET) is a real, sourced cost worth factoring into any resale math: the state levies a graduated rate on the seller's side of 1.10% on the portion of a sale price up to $525,000, 1.28% from $525,001 to $1,525,000, 2.75% from $1,525,001 to $3,025,000, and 3.00% above $3,025,000, per the Washington Department of Revenue, plus additional local REET that many cities and counties layer on top. For a representative $500,000-$650,000 Ilwaco sale, that puts state-level REET alone in the roughly $5,500-$7,600 range before any local add-on -- a real, budgetable cost of exit that should factor into any multi-year hold-period math, separate from any capital-gains tax question, which this research did not examine in enough depth to state a reliable figure for real estate specifically and so leaves undiscussed rather than guessing.

Rental Income: A Working Port Town, Not a Resort

Ilwaco's rental-income case is genuinely different from the ocean-facing towns just up the peninsula. This is not primarily a walk-to-the-beach vacation-rental market the way Long Beach or Seaview are -- Ilwaco fronts Baker Bay and the harbor, not open Pacific surf, and its year-round economic identity runs through the working port, Cape Disappointment State Park visitation, and history/heritage tourism (the Columbia Pacific Heritage Museum, the Lewis and Clark Interpretive Center) rather than a resort-condo product. On the short-term-rental side specifically, Ilwaco's own Municipal Code Chapter 15.41 sets real, zone-specific rules: vacation rentals are a permitted primary use in the R-3, R-4, R-5, C-1, C-2, and M-1 zones (with C-1/C-2 units required to sit behind or above a ground-floor commercial storefront), and are prohibited outright in the R-1 and R-2 residential zones -- meaning the zoning of a specific parcel, not just its location or charm, determines whether short-term rental income is even legally available there. This research could not directly refetch the city's own hosted copy of that ordinance this session (the hosting domain was blocked by this session's network egress policy), so this zoning detail should be reconfirmed directly with Ilwaco's planning department before underwriting any purchase on assumed rental income.

The more plausible steady-state rental case for much of Ilwaco's housing stock is long-term/annual rental to the town's own working population -- port employees, charter-fleet crew, and the broader Pacific County labor market -- rather than short-term vacation income, though any specific property's zoning should still be checked before ruling short-term use in or out.

Risk Factors Worth Weighing Before Timing a Purchase

Three real, sourced risk factors are worth naming plainly. First, and most significant: Cascadia Subduction Zone earthquake and tsunami risk. The Cascadia Subduction Zone, offshore of the entire Pacific Northwest coast, produces megathrust earthquakes of magnitude 9.0 or greater roughly every 300 to 600 years, and a resulting tsunami could reach the Long Beach Peninsula/Ilwaco area in as little as 15 to 20 minutes, with a wave as high as 30 feet possible within 30 minutes of the quake, per Washington DNR and Washington Military Department tsunami-hazard research. That risk is real and should not be minimized -- but Ilwaco has a genuine, documented advantage relative to the flatter parts of the peninsula: the town sits on real hillside terrain with natural high ground, and people near Cape Disappointment can reach safety on foot in as little as 15 minutes, versus a walk to safety from flatter Long Beach that can take as long as 75 minutes because natural high ground isn't reachable in time there. That distinction is concrete enough that Ocean Beach School District's plan to consolidate Hilltop Middle School and Ilwaco High School into a single new 6-12 facility, currently underway using state seismic-safety funding, is specifically sited on the existing Ilwaco High School site because it already sits on high ground -- while the district's separate elementary schools in flatter Long Beach and Ocean Park remain an unresolved seismic-safety problem the district is still actively studying, after voters rejected a $96.2 million bond that would have funded a new tsunami-safe elementary school in 2022.

Second, flood risk is real but genuinely limited in scope rather than town-wide: the City of Ilwaco's own FEMA information states that most of the city was removed from the mapped 100-year floodplain in the most recent preliminary maps (2013), with one specific area remaining mapped -- south of SR 101/Vandalia and around Mary Ann/Adelia south of Lake Street -- meaning flood-insurance requirements and cost genuinely depend on which specific parcel is being considered, not a blanket town-wide fact. Third, economic-base risk: Ilwaco's historic core industry, commercial and charter fishing, has contracted materially over decades -- the charter-boat count alone fell from roughly 130 operators in 1978 to roughly 9 by 2010 -- meaning a buyer should not assume the fishing economy alone will drive future demand or rental income the way it might have decades ago; tourism tied to Cape Disappointment State Park, the Lewis and Clark National Historical Park, and the broader Long Beach Peninsula draw is now a larger share of the area's real economic activity, and this page did not find a comprehensive, sourced current breakdown of Ilwaco's employment base by sector to state with more precision than that.

Bottom Line

Ilwaco is a small, genuinely working port town rather than a resort market, and the sourced data available on it -- home prices, income figures, appreciation trends -- carries real small-sample noise that this page has stated plainly rather than smoothed over. What's solidly documented: a genuinely low effective property tax rate, no state income tax offset by an 8.2% sales tax, a below-national-average homeowners insurance market, real but parcel-specific flood exposure, zone-specific (not town-wide) vacation-rental rules under Municipal Code Chapter 15.41, and a real Cascadia tsunami risk that Ilwaco is comparatively better positioned for than its flatter peninsula neighbors thanks to genuine natural high ground. This page is informational only. It is not financial, investment, tax, or legal advice, and nothing here should be used as the sole basis for a purchase or investment decision -- talk to a local Pacific County real estate agent, a financial advisor, and a licensed Washington insurance professional, and pull your own current comps, before making that call.
