Property taxes are one of the most important ongoing costs of homeownership at Koa Ridge. Understanding how Hawaii property taxes work can help you budget accurately and take advantage of available exemptions. Kristy and Austin Nakamura with the Kristy and Austin Home Group at Talk Realty help buyers at Koa Ridge understand all the costs associated with purchasing and owning a home in Central Oahu.
How Hawaii Property Taxes Are Calculated
Hawaii has some of the lowest property tax rates in the nation. Property taxes in Honolulu County are calculated by multiplying the assessed value of the property by the applicable tax rate. The City and County of Honolulu assesses properties annually, and the assessed value is typically based on fair market value as of October 1 of the preceding year.
For residential properties, the tax rate varies depending on the property classification. Owner-occupied homes receive a lower tax rate compared to investment properties or second homes. As of the 2025-2026 tax year, the residential rate for owner-occupied homes in Honolulu County is approximately $3.50 per $1,000 of assessed value.
Estimated Property Taxes for Koa Ridge Homes
New construction homes at Koa Ridge range from approximately $750,000 for townhomes to over $1.2 million for larger single-family residences. Using the owner-occupied residential rate, annual property taxes for a Koa Ridge home assessed at $900,000 would be approximately $3,150 per year, or about $263 per month.
Keep in mind that assessed values for new construction may differ from the purchase price. The county assessor evaluates properties based on comparable sales and other factors, so the assessed value may be lower or higher than what you paid.
Homeowner Exemption
Hawaii offers a home exemption that reduces the assessed value of your primary residence before taxes are calculated. For homeowners under 65, the current exemption is $100,000. For homeowners 65 and older, the exemption increases to $140,000. This means a $900,000 home with the standard exemption would be taxed on $800,000 instead of $900,000.
To claim the home exemption, you must file an application with the Real Property Assessment Division by September 30 of the year before you want the exemption to take effect. You must occupy the home as your primary residence.
Additional Tax Considerations for Koa Ridge Buyers
Buyers using VA loans or conventional financing should factor property taxes into their monthly mortgage payment through escrow. Your lender will typically collect property taxes monthly as part of your mortgage payment and pay them on your behalf.
New construction homes may also be subject to community facility district assessments or special improvement district fees that are separate from regular property taxes. At Koa Ridge, buyers should ask about any additional assessments tied to the community infrastructure.
