County figures are the Hawaii average adjusted for local market conditions. Actual rates vary by lender, credit score, and loan size.
In Honolulu County, property tax runs 0.28% of home value — $172/mo on the $739,000 median home. Low carry cost changes the math in your favor: your PITI leaves -40 points of DTI headroom versus the 43% ceiling before you account for other debt.
That headroom is a real asset. It's what lets you hold the 30-year fixed term instead of stretching to an ARM to afford the payment — the fixed-rate cost delta is roughly $277/mo on this loan size, and low-tax counties are where locking it costs you the least. Insurance still varies by zip ($150/mo here), but on the tax line you have no reason to compromise on term or rate structure.
Reality check: at an $80,000 household income, the PITI on the median home here runs about 40 points over the 43% ceiling — the headroom math above assumes income above that level. A larger down payment or an FHA loan (which allows up to 57% DTI) are the standard ways back under the line.
Your Honolulu County PITI sits above the standard DTI ceiling
On an $80,000 household income, the payment on the median home here runs about 40 points over the 43% ceiling. That doesn't mean the math is broken — it means the standard route is a bigger down payment, an FHA loan (up to 57% DTI), or a co-borrower. Run your real income through the DTI calculator before you fall for a listing.
