The Real Cost of 'Buying' Near South Point, Hawaii

Why There Is No Price to Quote

Ka Lae is overwhelmingly Department of Hawaiian Home Lands (DHHL) trust land, not privately platted subdivision lots. DHHL's own published South Point Resources Management Plan for the Kamaoa lands describes the area's natural and cultural resources as being in critical condition and lays out a plan to restore, preserve, and protect them -- the vocabulary of land stewardship, not real estate development. Layered on top of that ownership status, the South Point Complex is a federally recognized National Historic Landmark District, protecting the archaeological record of ancient canoe-mooring holes and heiau remains found there. Between DHHL trust ownership and landmark-district protections, there is no realistic path to a private residential purchase at the point itself, and this research did not find a single active MLS listing, subdivision plat, or fee-simple parcel for sale at Ka Lae.

That leaves an honest question: what are the search results people find when they look up "South Point real estate"? Overwhelmingly, they are listings for Ocean View -- formally Hawaiian Ocean View Estates and Hawaiian Ocean View Ranchos -- a large fee-simple subdivision of well over a thousand mostly one-acre parcels sitting roughly 11 miles north of Ka Lae, up-slope along Highway 11. Ocean View is a genuine, active market with real inventory, but it is a separate town with its own name, its own infrastructure story (much of it off-grid, on catchment water and often without county sewer), and its own set of buyer considerations -- it is not covered in depth on this page, and treating Ocean View listings as "South Point property" would be a meaningfully misleading conflation for a buyer trying to understand what they're actually purchasing and where.

Kau District Property Tax -- Real Numbers, for Context

Even without a Ka Lae-specific transaction to price, the county-level tax structure that would apply to any real Kau district purchase is a real, sourced fact worth knowing. Hawaii County's Real Property Tax Office set its FY2025-2026 Homeowner class (owner-occupied primary residences) at $6.15 per $1,000 of assessed value, and its Residential class (second homes, investment property, anything not owner-occupied) at $8.10 per $1,000 -- among the lowest nominal county property-tax rates anywhere in the United States. An age-based homeowner exemption further reduces the taxable assessed value by $40,000 to $100,000 for those who both own and occupy their home as a primary residence. Applied to a hypothetical $400,000 assessed Kau-area property: roughly $2,460/year at the Homeowner rate, or roughly $3,240/year at the Residential rate -- these are illustrative rate-times-value calculations, not an actual bill for any specific parcel, since no specific parcel is being priced here.

Hawaii's General Excise Tax, Not a Sales Tax

Hawaii does not levy a conventional state sales tax; instead it charges a General Excise Tax (GET) on nearly all business activity, including most real estate-adjacent transactions and rental income. The combined GET rate is 4.5% in Hawaii County -- a 4.0% state rate plus a 0.5% county surcharge that the Hawaii Department of Taxation confirms has been in effect since January 1, 2020, and is currently set to run through the end of 2030. GET is technically a tax on the seller's gross receipts rather than a tax on the buyer's purchase, but it is routinely passed through to the end customer in pricing, the way a sales tax would be -- a real structural difference from mainland sales-tax states worth understanding before assuming a mainland playbook applies here.

Insurance: Kau District Sits in Real Lava Hazard Zones

This is the single most important cost-and-availability fact for anyone considering property anywhere in the Kau district, including Ocean View. USGS's Lava Flow Hazard Zone map for Hawaii Island rates hazard on a 1-to-9 scale, with Zone 1 the most severe; Kau district spans Zones 1 through 3, because it contains the calderas and rift zones of both Mauna Loa and Kilauea, including Mauna Loa's southwest rift zone, which historically has sent lava across the district's main road (Highway 11) six separate times in a roughly 150-year span -- in 1868, 1887, 1907, 1919, 1926, and 1950. In the highest-hazard Zones 1 and 2 statewide, most private insurers have withdrawn entirely; the state-backed Hawaii Property Insurance Association (HPIA), an insurer of last resort, is often the only coverage available, capped at roughly $450,000 in coverage and running on the order of $6,000/year for a modest 1,200-square-foot home, versus roughly $1,400/year for a comparable Zone 3-or-higher home with normal private-market access. Any specific Kau district parcel's actual zone and insurability should be confirmed directly through a current USGS/Hawaii County zone lookup and an actual insurance quote, not assumed from the district-wide range stated here.

Utilities and Off-Grid Reality in the Broader Kau/Ocean View Area

Much of the Kau district's actual residential inventory -- concentrated in Ocean View rather than at the point -- was subdivided decades ago without full county infrastructure, and a meaningful share of parcels there still rely on rainwater catchment systems for water and individual septic or cesspool systems rather than municipal sewer; some more remote lots remain off the electrical grid, running on solar-plus-generator setups. This research did not obtain parcel-specific utility data (there being no specific parcel to research at Ka Lae), but any buyer evaluating real inventory anywhere in this district should treat water catchment, septic, and off-grid power as a live possibility to confirm on a given listing, not an edge case.

Bottom Line

There is no honest cost breakdown to give for property at Ka Lae / South Point itself, because there is no private market there -- it is Hawaiian Home Lands trust land and a protected National Historic Landmark District. What this page can responsibly offer instead is the real cost structure that governs the surrounding Kau district generally: Hawaii County's unusually low $6.15-$8.10 per $1,000 property-tax rates, the state's 4.5% GET in place of a sales tax, a lava-hazard-driven insurance market that ranges from normal to HPIA-only depending on zone, and a real chance of catchment water, septic, and off-grid power on older subdivided parcels. Anyone drawn to this area by the "South Point" name should start their actual property search in Ocean View, verify its own zone and infrastructure facts directly, and treat this page as an honest scoping exercise rather than a listing guide.
