Figuring out how much house you can afford in Waipahu starts with your income, your existing debts, and how much you have saved for a down payment. Lenders generally apply the 28/36 rule: your total monthly housing payment (principal, interest, property taxes, and insurance, known as PITI) should not exceed 28% of your gross monthly income, and your total monthly debt payments should not exceed 36%. The calculator above takes the stricter of those two limits to estimate the most you can borrow and the highest home price you can target in Waipahu.
The median home price in Waipahu is about $750,000. With a 20% down payment of $150,000 and a 6.75% rate on a 30-year loan, the monthly payment for principal, interest, property tax, and insurance comes to roughly $4,298. Under the 28% front-end guideline, supporting that payment takes a household income of around $184,000 per year. Waipahu has a cost-of-living index of 178 (US average = 100) and a median household income of $90,000, so local buyers often stretch their budgets or save longer for a larger down payment.
Property taxes matter too: the effective rate near Waipahu is about 0.3% of value per year, which adds roughly $188 a month on a median-priced home. Homeowner's insurance, and private mortgage insurance (PMI) if you put down less than 20%, push the payment higher. Renters comparing their options should weigh the average 1-bedroom rent of about $1,900/month against the full cost of owning, including maintenance and closing costs. Use the tool above with your real numbers to see exactly where you stand in the Waipahu market.

It depends on your income, debts, and down payment. Using the standard 28/36 rule, a Waipahu household earning the local median of $90,000 with a 20% down payment and a 6.75% rate can typically afford a home in the range that the calculator above estimates. The median home price in Waipahu is about $750,000, so compare your result to that benchmark.
To buy the median Waipahu home of about $750,000 with 20% down ($150,000) at a 6.75% rate over 30 years, the monthly payment (principal, interest, property tax, and insurance) is roughly $4,298. Under the 28% front-end rule, that implies a household income of about $184,000 per year.
The 28/36 rule is a common mortgage-qualifying guideline. Your total housing payment (PITI) should stay under 28% of gross monthly income (the front-end ratio), and all monthly debt payments combined should stay under 36% (the back-end ratio). The calculator above applies both limits and uses the lower one to estimate the most you can afford in Waipahu.
A 20% down payment on the median Waipahu home of $750,000 is about $150,000, which avoids private mortgage insurance (PMI). Many buyers put down less: FHA loans allow 3.5% (about $26,250), and conventional loans can go as low as 3%, though a smaller down payment means PMI and a larger loan.
Average 1-bedroom rent in Waipahu is about $1,900/month, which is below the estimated monthly cost of owning the median home (roughly $4,298 for principal, interest, tax, and insurance with 20% down). Buying also builds equity and is affected by property taxes near 0.3% and closing costs, so compare your own numbers in the calculator above.
