Planning a purchase in Hawaii
The prefilled price, tax percentage, and interest rate are illustrative inputs, not verified Hawaii averages or lender quotes. Replace them with the property's price, a local tax estimate, an insurance quote, and your lender's rate.
Property-tax administration is at county level
Hawaii's Department of Taxation directs real-property tax questions to the counties. State income-tax guidance is not a substitute for the property-tax assessment and classification that applies to the home's island and county.
For your estimate: Follow the county links to identify the parcel classification and annual liability. Enter that estimate, rather than assuming a single Hawaii property-tax percentage.
Hawaii Taxation: county tax resourcesHonolulu buyers should check Residential A status
In the City and County of Honolulu, Residential A classification depends on property characteristics, assessed value and the absence of a home exemption. This is a Honolulu rule, not a statewide classification for every Hawaii home.
For your estimate: For an Oahu property, ask whether your intended occupancy and exemption approval change the classification used in the tax quote. For another county, use that county's rules instead.

Using local estimates in this tool
The tax field multiplies the home's price by a percentage. If your assessor estimates an annual tax bill, divide that bill by the entered home price and multiply by 100. Do not enter an assessment ratio or millage directly. For example, an illustrative $4,800 annual bill on a $400,000 price corresponds to 1.2%; these are not local averages.
This payment includes principal, interest, property tax and home insurance. Budget mortgage insurance, HOA dues, maintenance and closing costs separately.
Official resources and next steps
HUD housing and homeownership resources for Hawaii provides further counseling and housing contacts.
For FHA financing, use HUD's county and unit-count lookup. Select Hawaii, the property's county, the calendar year, and the number of units. The 2026 national one-unit floor of $541,287 is a baseline, not a determination of the limit for every county in Hawaii.

How to Use This Mortgage Calculator in Hawaii
Enter the price of the property you are considering in Hawaii, then adjust the down payment and rate. The payment combines principal, interest, property tax, and insurance. It does not include HOA dues, maintenance, or mortgage insurance.
For example, at the illustrative price of $835,000 and 10% down, the base loan is $751,500. These are calculation examples, not a statement about prices or typical buyers in Hawaii.
Compare the same home under different rates and down payments. A lower monthly payment from a longer term can still mean more lifetime interest. Confirm taxes and insurance for the property before relying on the estimate.
