Approaching $525,000 the NT’s quadratic formula peaks in steepness — each extra $10,000 of price adds more duty than the last $10,000 did. Past that point flat percentages of the whole price take over. No first-home concession exists, but new house-and-land packages carry no duty for anyone.

Duty is only one line of the day-one bill. With less than a 20% deposit, lenders mortgage insurance joins it — priced from published LVR bands by our LMI calculator:
| Path | Deposit | LMI (incl. its duty) | Duty + LMI |
|---|---|---|---|
| 20% deposit | $110,000 | $0 | $27,225 |
| 15% deposit | $82,500 | $4,983 | $32,208 (85% LVR) |
| 10% deposit | $55,000 | $10,198 | $37,423 (90% LVR) |
Owner-occupier duty used; LMI varies by lender and insurer, so treat it as indicative. NT Land Titles Office's registration fees add $362 at this price ($181 transfer + $181 mortgage) — the state calculator itemises them live.
