The Real Cost of Living in Waimea (Kamuela), Hawaii

The Headline Price -- Two Sources, a Real Gap

Two of the market's most-cited data sources disagree meaningfully on where Waimea prices currently stand, and this page states that gap honestly rather than picking a favorite. Redfin's reported figures put Waimea's median sale price over the trailing 3 months at roughly $1.1 million, down about 3.6% from the same period a year earlier, with median price per square foot at $655, up a striking 25.2% year-over-year -- a combination that suggests smaller, higher-price-per-square-foot homes are driving recent sales even as the overall median softened slightly. Zillow's separate typical-home-value estimate (a smoothed valuation index, not a median of actual closed sales) runs meaningfully lower, around $841,000, down about 5.8% over the past year. Homes are also taking longer to sell than a year ago -- roughly 138 days on market on average, up from 120 -- with 20 homes reportedly sold in April of the year checked, down slightly from 22 a year earlier.

The practical takeaway: Redfin's closed-sale median and Zillow's valuation index are measuring different things (actual transaction prices for the homes that sold vs. a broader, smoothed estimate across the whole housing stock), and both show a market that has cooled somewhat from its recent peak rather than one still accelerating. Current active listings on Zillow have ranged from roughly $485,000 for condos up to $1.5 million-plus for larger single-family homes, giving a better sense of the real spread than either single median.

Property Tax: Hawaii County's Real, Sourced FY2026-27 Rates

Hawaii County's Council adopted its FY2026-27 property tax rates via Resolution 574-26 on May 21, 2026, effective July 1, 2026. The owner-occupied residential rate is $5.75 per $1,000 of net assessed value; non-owner-occupied residential (a second home or a straight rental) is taxed at $8.10 per $1,000; and agricultural land or native forest is taxed at $9.35 per $1,000 -- relevant in Waimea specifically, since many parcels here carry agricultural or ranch-adjacent zoning and use classifications tied to the town's Parker Ranch heritage. Applying the owner-occupied rate directly: an $841,000 home (Zillow's typical-value figure) carries a tax bill of roughly $4,836/year; a $1.1 million home (Redfin's median), roughly $6,325/year. These are straightforward rate-times-assessed-value calculations, not actual county bills -- a specific parcel's assessed value is set by the county's own periodic assessment and can run above or below current market price, and Hawaii County's homeowner exemption further reduces the taxable value for a qualifying owner-occupant. Confirm a specific parcel's current assessment, use classification, and any exemption directly with the Hawaii County Real Property Tax Office.

The General Excise Tax -- Hawaii's Stand-In for a Sales Tax

Hawaii levies no separate state sales tax. Instead, a General Excise Tax (GET) is charged on businesses' gross receipts -- 4% statewide plus a 0.5% Hawaii County surcharge, for a combined 4.5% on most Big Island retail transactions and services, with businesses legally permitted to pass on up to about 4.712% to also cover the GET owed on the passed-through amount itself. For a household relocating from a mainland state with a conventional sales tax, this is a real structural difference that touches nearly every everyday purchase, not just the real estate closing.

Water Supply: A Real, Current Drought Story, Not a Hypothetical

This is the fact that distinguishes Waimea's real-cost picture from a typical mainland upcountry town, and it should not be glossed over: as of early 2026, the Hawaii County Department of Water Supply had a Water Restriction Notice in effect for a defined swath of South Kohala customers -- including Waimea Town itself, Lalamilo Farm Lots, portions of Mana Road and Mamalahoa Highway, and several named subdivisions -- requiring affected households to cut water use by at least 25% and irrigation customers by at least 50%. That notice replaced a less-severe Water Conservation Notice that had already been running since spring 2025, and the U.S. Drought Monitor classified the area as experiencing Moderate to Severe drought, with local officials describing conditions in Waimea, Kohala, and Hamakua as a genuine crisis. This is a real, sourced, documented water-supply issue tied to prolonged lack of rainfall -- distinct from lava or hurricane risk -- and any buyer here should ask directly, before closing, whether a specific property is on county water (subject to these restrictions), an agricultural irrigation meter (subject to the steeper 50% cutback), or a private catchment/well system, and confirm the county's current restriction status, since it can change with rainfall conditions.

Insurance and Utilities

Hawaii homeowners policies commonly exclude windstorm/hurricane coverage from the base policy, requiring a separate rider -- a statewide structural fact. Hawaii also maintains the HPIA FAIR Plan as an insurer of last resort (with a coverage cap commonly cited around $450,000, well below many Waimea home values) and reactivated the Hawaii Hurricane Relief Fund in 2024 to help stabilize a property-insurance market under real, disclosed pressure from major climate events and rising premiums statewide. This research did not obtain a Waimea-specific premium quote; get an address-specific quote from a licensed Hawaii agent. On utilities, Hawaii Island is served by Hawaii Electric Light Company (HELCO), and the state's residential electricity rates rank among the nation's highest due to its isolated, imported-fuel-dependent grid -- a real cost factor that applies regardless of which Big Island town a buyer chooses.

Putting the Real Number Together

For a representative $850,000-$1.1 million owner-occupied Waimea purchase, a realistic annual recurring-cost floor looks roughly like: $4,890-$6,325 in Hawaii County property tax at the FY2026-27 owner-occupied rate (before any homeowner exemption); a homeowners policy plus a separate hurricane rider; electricity costs running above the national average given HELCO's rate structure; the 4.5% GET embedded into most day-to-day purchases; and, uniquely relevant here, a real possibility of water-use restrictions during drought periods that could affect irrigation, landscaping, or agricultural use on a given parcel. None of these figures substitutes for an actual county tax card, actual insurance quotes, a current water-restriction status check with the county, 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.
