Unfortunately, if you are choosing to rent to own your property, you will not be eligible for the First Home Owners Grant to use towards your Kickstarter payment because the property will initially be owned by PublicSquare or a participating landlord, not you.
If you choose to buy a property upfront with a mortgage using PublicSquare's Deposit Stacker initiative, you will be eligible for all applicable grants and home loan support in your state including the new homebuilder grant if the property is brand new.
