Looking to purchase established property in Brisbane. Single no dependants, $65k + Super income, about $60k deposit, no debts, one credit card (no outstanding balance) that I will cancel when I apply, first home buyer (but no grant because it is an established property). Using online calculators my borrowing power is about $400k. I would like to see if I have any options to raise this up to closer to $480-500k. I am looking to buy a 3 bedroom home, and plan to eventually rent 2 of the bedrooms out to friends. Is there a way to count the expected rental income from this towards my income for borrowing power? Or is there a way for my parents to contractually guarantee my repayments to boost my borrowing power, without them owning part of the property? Any other thoughts?
