Beyond the Mortgage: Hidden Costs
Your mortgage payment is only part of the picture. Here's what else goes into the true monthly cost of owning an $800K home in Hawaii:
| Cost | Monthly | Annual |
|---|---|---|
| Mortgage (P&I at best rate) | $3,436 | $41,228 |
| Property Tax (~0.35%) | $233 | $2,796 |
| Homeowner's Insurance | $200 | $2,400 |
| Maintenance (~1%/yr) | $667 | $8,000 |

* Condo buyers should add HOA fees ($300–$800/mo typical in Honolulu). Property tax rates vary by county and exemption status.
Closing Costs in Hawaii
Before you even make your first payment, you'll need to cover closing costs. In Hawaii, these typically run 2–5% of the purchase price:
- Origination fees: 0.5–1% of loan amount ($3,200–$6,400)
- Title insurance: ~$2,000–$3,500
- Escrow/closing fees: ~$1,500–$2,500
- Prepaid taxes & insurance: ~$3,000–$5,000
- Appraisal, inspection, survey: ~$1,500–$2,500
- Points (if buying down rate): varies (e.g., 2 points = $12,800)
Estimated total closing costs: $16,000–$40,000 on an $800K purchase, depending on lender, points, and negotiation.
Income Needed to Qualify
Most lenders target a debt-to-income (DTI) ratio of 43% or less. With a total monthly housing cost of ~$3,869, you'd need a gross household income of roughly $107,972/year ($8,998/month) assuming no other debts. Add a car payment and student loans, and the required income goes higher.
