Can I buy property for my SMSF that I already own personally?
In some instances yes, it will depend on whether the property is residential or commercial. You can buy a commercial property that you already own and even borrow against it as long as you meet the borrowing criteria i.e. a maximum LVR of 72% for residential property and 63% for Commercial Property.
If you want to buy a residential property then it must be at arms length and not currently owned by a related party, it must be purchased from and leased to an unrelated third party.
