I've got a 3 investment properties. All have gone up in value in the last 3 years. One example is now worth $650k and my interest-only mortgage of $488k is with CBA at 4.84% pa so I pay $2,000 a month with no extra fees. Surely you can do better than that ? The website only reports principal+interest loans which are > $500 more expensive. As this is an investment I want an interest only loan.
