How to read the result
The big number is the gap between the two. It is not money you save — stamp duty and a deposit are still ahead of you under Rent-to-Own, paid when you buy in years four to eight — but it is money you do not need to have now. Try the 5% deposit setting to see the mortgage route at its cheapest: the deposit is smaller, but lenders mortgage insurance appears.
What the calculator assumes
- Stamp duty is calculated at each state's owner-occupier rates, with first-home buyer concessions applied when you tick that option.
- Lenders mortgage insurance is estimated at 4.2% of the loan on a 5% deposit, 1.9% on 10%, 0.9% on 15% and nil at 20%. Real premiums vary by lender.
- Mortgage route: $2,000 conveyancing and $600 building and pest.
- Rent-to-Own route: $1,100 engagement fee (refundable if the acquisition does not reach unconditional), $1,100 independent legal advice, $2,000 rental bond, and a setup fee of 0.99% of the initial home value on an established home (nil on a new home from the building panel).
- The program's initial home value is between $500,000 and $1,000,000.
Frequently asked questions
Yes, but later. Stamp duty is paid when you buy the home, in the purchase window between years four and eight, at the rates and concessions that apply then.
