The median home price in Waipahu is about $750,000, and the City and County of Honolulu has an effective property tax rate near 0.3% of value per year. Hawaii levies a graduated state income tax up to 11% (the highest top rate in the country) and funds local services through county property taxes that are low by national standards, though the nation's highest home prices keep the dollar amount meaningful. Businesses pay a General Excise Tax rather than a traditional sales tax.

A common guideline keeps housing payments (PITI) under 28% of gross monthly income. On a $750,000 home with 20% down at 6.75% over 30 years, plan for a healthy six-figure household income to stay within that guideline in Waipahu.
Average rent in Waipahu is about $1,900/month for a 1-bedroom and $2,400 for a 2-bedroom. Compare that to the calculated PITI payment above. In Hawaii's extremely high-priced housing market, buying costs far more per month than renting for years, so compare both very carefully.
