How much can I borrow in New Zealand?
NZ lenders assess affordability based on income expenses and existing debts. A rough guide: 5-6x combined household income for well-qualified borrowers. A couple earning $120000 combined could borrow approximately $600000-$720000 depending on debts and expenses. First Home Grants provide up to $10000 for new builds.
Weekly vs fortnightly vs monthly payments?
Fortnightly payments (26 per year) are common in NZ and effectively make one extra monthly payment per year. On a $500000 loan at 6.5%: monthly = $3161 fortnightly = $1458 weekly = $729. Fortnightly payments save approximately $45000 over the loan life versus monthly due to more frequent principal reduction.
Should I fix or float in NZ?
In a falling rate environment floating (variable) lets you benefit immediately. In a rising environment fixing protects your budget. A common NZ strategy: split your mortgage 50/50 between fixed and floating or fix portions for different terms (1-year 2-year 3-year) to average out rate movements.
