The Real Cost of Owning Property in Waianae, Oahu

The Headline Price: Genuinely Lower Than the Rest of Oahu

Redfin's Waianae housing-market page reports a $333,000 median sale price as of March 2026, down 29.9% year-over-year, with price per square foot at $415 (also down, 15.7% year-over-year). That is a real, substantial gap below Oahu's islandwide median (roughly $1.2 million as of mid-2026 per broader Oahu market reporting) -- Waianae and neighboring Makaha are consistently cited by local real estate sources as home to the most affordable single-family housing accessible to a median-income Oahu family, concentrated specifically in this Leeward stretch of the island. Makaha itself shows a somewhat higher reported median around $630,000, giving a sense of the price gradient within the broader Waianae Coast area.

As with several of this North Shore/Leeward batch's smaller markets, a nearly 30% year-over-year decline in a market this size should be read with some caution -- lower transaction volume can swing a reported median substantially based on which specific homes happened to sell. This page states the figure as reported rather than smoothing it over, while flagging that a longer trailing window or a direct comparative market analysis would give a more reliable current number.

Property Tax: The Same Honolulu System, at a Lower Effective Bill

The City and County of Honolulu taxes all Oahu property under the same class system regardless of neighborhood. For fiscal year 2025-26, an owner-occupied home with a filed home exemption pays $3.50 per $1,000 of net taxable value, after subtracting the exemption amount ($120,000 under age 65, $160,000 at 65 or older) from the assessed value. Given Waianae's roughly $333,000 median sale price, the vast majority of Waianae home purchases sit nowhere near the $1 million Residential A threshold that raises property tax bills meaningfully in pricier North Shore or Windward markets -- a real, structural advantage of buying here, and one directly connected to the honest income and affordability context covered elsewhere on this page: lower assessed values genuinely translate into lower property tax bills for Waianae owners.

For a home purchased near the $333,000 median with the home exemption filed and subtracted, the resulting property tax bill works out to a modest annual figure -- meaningfully lower in absolute dollar terms than almost any other market in this Oahu batch, simply because the underlying home value is lower. Get an actual parcel-specific assessed value from the City and County of Honolulu before budgeting a precise number, since assessed value and market sale price aren't always identical.

No Sales Tax, But a Real GET -- and Real Local Income Context

Hawaii's General Excise Tax (GET) applies here the same as anywhere on Oahu: a combined 4.5% on business gross receipts (4% state, 0.5% county), commonly passed through at an effective rate closer to 4.712%, in place of a conventional sales tax.

What's specific and important to state honestly about Waianae is that its comparatively low home prices don't mean a low overall cost burden for many local residents. Reported median household income for Waianae ranges from roughly $67,000 to $82,000 depending on the source and year, both figures below Hawaii's statewide median household income (cited around $73,000 in some sources), and reported poverty rates run from roughly 16% to 21%, above the national average. A buyer relocating to Waianae specifically for its affordability should understand that the same general Hawaii cost-of-living premium on groceries, fuel, and imported goods applies here as everywhere on the island, layered onto a local income base that is genuinely lower than Oahu's average -- meaning the community's overall affordability picture is more complicated than a low median home price alone suggests. This page states that honestly rather than presenting low prices as evidence of low cost of living across the board.

Insurance and Housing-Market Context

Waianae's coastline carries standard Oahu coastal insurance considerations -- flood coverage requires a separate NFIP or private policy in FEMA-mapped hazard zones, and this research did not compile specific current Waianae premium figures this session. What's more distinctive to this market is the broader housing-affordability and housing-security context: Waianae is home to Puʻuhonua o Waiʻanae, the largest homeless encampment on Oahu (roughly 200 residents near the Waianae Boat Harbor), and the district has the highest concentration of Native Hawaiian residents and unsheltered Native Hawaiian homelessness on the island. That context doesn't change an individual buyer's own insurance math, but it's a real, relevant part of understanding the community a purchase here becomes part of, and this page includes it rather than treating real cost of ownership as purely a private-transaction question.

Putting a Realistic Annual Cost Picture Together

For a Waianae purchase near the $333,000 median with a home exemption filed, expect a property tax bill well under $1,000 per year at the $3.50 rate on the exemption-reduced assessed value -- genuinely lower than any other market in this Oahu batch in absolute dollar terms. Add Hawaii's 4.5% combined GET on most purchased goods and services and the general island cost-of-living premium that applies statewide, and factor in that this is a community with real, documented income and housing-security challenges among many of its existing residents, which is worth understanding as context even though it doesn't change an individual buyer's own tax and insurance math. None of these figures substitutes for an actual parcel-specific tax estimate, actual insurance quotes, and a direct local comparative market analysis before making an offer.
