Could you handle another 1% increase in interest rates?
Keep the property through difficult periods.
Best for: Owners with variable-rate or soon-to-roll loans
This isn't about forecasting where rates go — nobody reliably does. It's scenario planning: if your rate moved 1% tomorrow, what exactly would happen to your monthly position?
Why this matters
Owners who've run the scenario respond to rate moves with a plan. Owners who haven't respond with panic — and panic decisions about property are expensive.
POTENTIAL IMPACT
1% on a $500,000 loan = about $5,000 per year in extra interest
What to check
- Your current loan balance and rate
- What a 1% higher rate does to the monthly repaymentRoughly: loan balance × 1% ÷ 12. On $500,000 that's about $417 a month.
- Whether your buffer absorbs that for 6-12 months while you adjust
- Which levers you'd pull if it happenedRent review, rate negotiation, cost trims — decided now, calmly.
