Kailua mortgage calculator
A median-priced Kailua, HI home at 6.75% over 30 years, with Hawaii property tax of 0.29% and $1,600 a year of homeowners insurance. Every figure below is computed on our amortising engine — nothing is estimated in the browser.
$7,767 a month, all in
Principal and interest are $6,865; escrow and PMI add the rest. Over the full term the loan costs $1,412,914 in interest. Discounted at 5%, buying here has a net present value of $-106,072 ($514,916 in today’s dollars).
Within Hawaii, Kailua is the most expensive of the 3 Hawaii markets covered here. Prices here run 2.15x those in Hilo, the cheapest market listed, so a statewide average badly understates what a purchase costs on this side of the state.
The price-to-rent ratio here is 26.9 ($1,176,000 to buy, $3,640 a month to rent), which is high. Renting and investing the deposit is a genuine alternative in Kailua, not a fallback position.
Kailua carries a premium over the rest of Hawaii: a median home here runs $1,176,000, about 40% above the state median of $840,000. The deposit moves with it, so the same 20% down is $235,200 rather than $168,000.

Where these numbers come from
Hawaii medians come from editorial and are refreshed weekly. The Kailua figures index those state medians to the local market, so they track the same feed rather than going stale. Insurance and the state income tax rate are editorial. Treat everything here as a planning estimate, not a quote.
