Monthly payment, the income lenders expect, and how many years it takes to save a down payment at island prices.

$7,504/mo

to own a $1,139,000 house in Oʻahu with 10% down. Lenders usually want that to be no more than 28% of your gross income.

The monthly payment

Principal and interest$1,025,100 borrowed over 30 years$6,479
Property taxAbout 0.35% a year, owner-occupied$332
Homeowners insurance$180
Mortgage insuranceCharged until you reach 20% equity$513
Total$7,504

Over 30 years you would pay about $1,307,459 in interest alone.

The income it takes

Income this home needs$321,604
Median household income, Honolulu$106,195

A household earning the median would need $215,409 more a year to afford this home comfortably.

Median income: U.S. Census ACS (ACS 2020–24).

Saving the cash to close

You need the down payment of $113,900 plus about $22,780 in closing costs.

11.3 years

saving $800 a month at 4% a year, assuming prices stay where they are. If home prices rise while you save, the target moves too.

Many first-time buyers in Hawaiʻi lean on programs this tool does not model: down payment help from the Hawaiʻi Housing Finance and Development Corporation, county first-time buyer programs, Department of Hawaiian Home Lands leases for eligible Native Hawaiians, and help from ʻohana.

›How this is calculated

Principal and interest use the standard fixed-rate mortgage formula: payment = loan × r ÷ (1 − (1 + r)^−360), with r the monthly rate.

Property tax rates are rough effective rates for owner-occupied homes after typical exemptions, and insurance, condo fees, mortgage insurance (0.6% of the loan a year below 20% down) and closing costs (2% of price) are assumptions for teaching.

Neighbor-island condo prices are estimated at half the county single-family median because a comparable published median was not available.
