Struggled for a title on this one, anyway. So far I have been purchasing in my own name and my partner (currently de facto) in her name. Our new PPoR will be in both names. In the future it is likely we would like to set up a LOC on one property, owned my myself, to purchase a property owned only in my partner's name (and/or vice versa). Will this scenario leave the interest on the LOC as tax deductible? Is there a better way to do this that will? What other considerations are there? Main reasons for holding in one name are to keep below land tax thresholds (not sure which states allocate by ownership and which allocate full amount to both) and to control income tax for each person with negative/positively geared properties. I'm sure there are other considerations I don't even know about. Thanks!
