Hi All, I purchased a substantial property in Brisbane 4 years ago together with my brother and parents. I have lived there for 4 years and recently moved out with my partner. My brother only lives there on weekends and my parents (in their late 60s) live there full time. We all own a 1/4 share of the property, both my brother and I have mortgages on our shares, mine is 100% of my share paying interest only. As the property is no longer my primary residence is it classed as an investment property despite my parents living in it and not paying any rent. Can I claim this as an investment property or do I need some sort of official agreement that it is "rented" or the like ? As I am now living elsewhere and paying rent in a different property and NOT generating a return for my investment I am looking for options or legal tax deductions for next financial year and what I may have to do to legally claim them. If I am able to claim this as an investment can I claim the full amount of my interest payments on the loan ? even if this is totals nearly all of what I pay in tax each year ? I appreciate any advice or ideas.. Cheers.
