You can have your SMSF own the commercial property you operate your business from – market rental conditions should still apply

small business concessions won't apply if it is not an "active asset" (i.e. used to operate business in an entity connected with you) for at least 50% of the time you own the property. 

How old are you? Do you receive employment income? Could super be any option?

Whilst not exactly on topic, don't forget to ensure the structure of your SMSF and bare/property trust are correct before proceeding to contract. Over the last 6 months I have dealt with many lenders who all have different rules as to who they expect the trustee of your SMSF and bare/property trust to be.
