- Pay it upfront: Stamp duty is due within 30–90 days of settlement depending on the state. Most buyers pay it from their deposit savings, so factor it into your "money to put aside" number — not just your loan.
- It's not borrowable: Banks generally won't lend you money to pay stamp duty. You need it in cash on top of your deposit.
- It changes with price: Even a $50,000 increase in purchase price can push you into a higher bracket, especially in NSW and VIC.
