The Real Cost of Owning in Kailua-Kona

Purchase Price: A Thinner, More Volatile Market Than It Looks

Multiple market-tracking sites give meaningfully different snapshots of Kailua-Kona home prices, and the disagreement itself is worth understanding before anchoring a budget to any single number. A May 2025 snapshot put the single-family median at roughly $1.06 million, up about 11% year-over-year with 402 homes on the market. Mid-2026 year-to-date figures from a different source put the single-family median at about $1.225 million, down 6.1% from the prior year and roughly 2% below the 2025 year-end median -- a real, reported cooling after the earlier run-up. A separate automated home-value estimate (a modeled figure, not a sale-price median) put typical home value around $824,000, down about 2.1% over the trailing year. These figures don't reconcile cleanly with each other, and that's a genuine feature of a market this size and this seasonal: Kona's sales volume is thin enough that a handful of unusual closings -- a cluster of luxury oceanfront sales, or a run of smaller starter-condo turnover -- can swing a monthly or even quarterly median meaningfully without reflecting a real structural shift.

Condos moved in a similar direction: a mid-2026 year-to-date figure put the condo median at roughly $570,000, down 12.3% year-over-year and back to levels last seen in 2023. Within the broader Kona district, price points vary sharply by neighborhood -- Holualoa, the coffee-and-arts village above town, has run toward the top of the range at roughly $960,000 to $1.07 million median, while South Kona communities like Kealakekua and Captain Cook have run noticeably lower, in the roughly $700,000 to $795,000 range in the same snapshots. Treat any single site's median or trend label cautiously in a market this size, and ask a Kona-focused agent for a trailing-90-day figure broken out by the specific neighborhood and property type you're considering rather than an island-wide or district-wide average.

Property Tax: A Real, Tiered Classification System

Hawaii County runs its own property tax classification system, entirely separate from Honolulu, Maui, or Kauai counties, and the classification your property is assigned matters as much as the assessed value itself. For FY2026-27 (effective July 1, 2026, adopted by the Hawai'i County Council on May 21, 2026), the owner-occupied homeowner rate is $5.75 per $1,000 of assessed value, down from $5.95 the prior year -- among the lowest homeowner rates of any Hawaii county. Non-owner residential (a second home or investment property not qualifying for the homeowner classification) runs on a three-tier structure: $11.10 per $1,000 on the portion of assessed value up to $2 million, $14.50 on the $2-4 million portion, and $17.00 on any value above $4 million -- meaningfully higher than owner-occupied, and progressively steeper at higher valuations. A separate long-term rental classification, set at $7.75 per $1,000, sits between those two. Commercial and industrial property both run $10.70 per $1,000, apartment-classified property runs $11.70, agricultural and native forest land runs $9.35, and conservation and hotel/resort classifications both run $11.55.

This site's research found real disagreement between sources on these numbers -- one aggregator cited an owner-occupied rate of $6.15 and a flat non-owner residential rate of $8.10, figures that don't match the FY2026-27 rates reported by Big Island Now's coverage of the County Council's actual rate-adoption vote. That discrepancy is most likely explained by the other source citing a prior fiscal year or an outdated snapshot rather than the current adopted rate, but this page did not independently verify that explanation against the county's own published rate table, and states the disagreement honestly rather than picking whichever number sounds better. The homeowner exemption -- which reduces the taxable value before the rate is applied -- has a $50,000 baseline that increases automatically with the owner's age, a real, meaningful reduction for anyone who qualifies by living in the property as a primary residence. This site's Property Tax Guide for Kona covers the classification system, the homeowner exemption, and the filing process in more depth.

General Excise Tax: A Broader-Based Tax Than Mainland Buyers Expect

Hawaii's General Excise Tax (GET) is structurally different from a mainland sales tax, and it's worth understanding before budgeting ongoing costs. GET is a tax on business gross income, not narrowly on retail sales, which means it applies more broadly -- to services, professional fees, and rental income, not just goods purchased at a store -- and it is commonly passed through to the customer as a visible line-item, functioning in practice like a sales tax even though it's structured differently. Hawaii County's GET rate is 4% (versus 4.5% on Oahu). Anyone renting a Kona property short-term needs to budget GET on that rental income alongside the transient accommodations tax layers described below; anyone hiring local contractors, property managers, or service providers for ongoing home maintenance should expect GET to show up on invoices for those services as well, a real, recurring cost line that a mainland buyer's prior homeownership experience likely didn't include.

Transient Tax Stack: Three Separate, Additive Layers If You Rent

If any part of the plan for a Kona property involves short-term rental income, budget three separate tax layers, not one combined percentage. The state Transient Accommodations Tax (TAT) rose from 10.25% to 11%, effective January 1, 2026. Hawai'i County layers its own 3% county TAT on top, a separate, county-level mechanism distinct from the state rate. And the state's 4% General Excise Tax applies to the rental income itself, on top of both TAT layers. None of this is optional or avoidable through structuring -- it's the standard tax treatment for transient accommodations income in Hawaii County as of this research pass. A buyer purely planning personal or long-term-tenant use, with no short-term-rental activity, would not owe the TAT layers at all, but would still owe the annual property tax bill (likely at the non-owner residential or long-term-rental classification, not the lower owner-occupied rate, unless the buyer lives in the property as a primary residence).

Layered on top of the tax picture, Hawaii County's own short-term-rental regulatory framework is genuinely in flux as of this research pass: a registration requirement (Ordinance 25-50 / Bill 47) has a compliance deadline extended to September 1, 2026, and county estimates suggest roughly half of the island's approximately 8,008 short-term-vacation-rental units were still unregistered as of the most recent reporting found, with the county estimating it is missing roughly $12 million in TAT and $1.6 million in GET revenue annually as a result of that non-compliance. This site's Vacation Rental Investment page for Kona covers the regulatory and zoning side in more depth; this page's point is narrower -- the tax math on a compliant rental is three real, additive layers, and Kona's own STVR compliance rate suggests a meaningful share of current operators may not be paying them correctly.

Insurance: A Genuinely Unsettled Market Right Now

Hawaii's property insurance market, particularly for condominiums, has been through real, documented instability in the past two years. Legislative testimony in 2024 put the number of Hawaii condo buildings underinsured for hurricane risk at somewhere between 375 and 390, with some condo association premium increases reported as high as 1,000%. Governor Josh Green issued an emergency proclamation in August 2024 to stabilize the market, and the state's Hawaii Hurricane Relief Fund began accepting applications in June 2025 for excess hurricane coverage on condo and townhouse associations -- but only as coverage above a $10 million threshold, meaning associations must still secure the first $10 million in primary hurricane coverage from private insurers. This matters directly for a Kona condo buyer: Fannie Mae and Freddie Mac generally won't purchase loans on units in buildings that aren't insured to full replacement value, so an underinsured association can functionally freeze conventional financing for every unit in the building, not just the specific one being purchased.

No Kona-specific windstorm or flood insurance premium figure was confirmed during this research pass -- premiums vary too much by building, coverage level, association master-policy status, and individual carrier appetite to state a single reliable number. Before making an offer on any Kona condo, ask the association directly for its current master policy's coverage-to-replacement-value ratio and its most recent premium history, and get an actual quote from a Hawaii-licensed insurance broker rather than assuming a figure found online applies to a specific building.

Adding It Up: A Framework, Not a Guaranteed Number

There is no single, verified 'true cost of ownership' figure this page states as settled fact, because the largest variable line items -- windstorm and flood insurance premiums, individual condo association dues, and the specific classification a given parcel will actually be assigned -- depend on the exact property, not the market generally. What can be said with sourced confidence: a homeowner-occupied Kona property carries a $5.75-per-$1,000 county property tax rate for FY2026-27 (before the $50,000-plus homeowner exemption reduces taxable value), a non-owner or investment property carries a meaningfully higher tiered rate starting at $11.10 per $1,000, GET at 4% applies broadly to services and any rental income, and any short-term-rental plan needs to budget an 11% state TAT, a 3% county TAT, and 4% GET as three separate, additive layers on top of the property tax bill -- plus genuine current uncertainty in the windstorm and flood insurance market that makes a single confident premium figure impossible to state responsibly right now.

Before making an offer, get current, written numbers from the actual sources: the Hawai'i County Real Property Tax Division for the exact classification and rate a specific parcel will carry, a Hawaii-licensed insurance broker for windstorm and flood premiums and (for condos) the specific association's master-policy status, Hawaii County's Planning Department for short-term-rental registration and zoning status if rental income is part of the plan, and a Kona-focused buyer's agent who can pull recent, neighborhood-specific comparable sales rather than a district-wide average.
