This is where mum and dad let you use the equity in their home to make up the deposit for your house. For example, you might put in 5% cash plus a guarantee equal to 15% from ma and pa. The beauty of having parental help to guarantor, gift or boost your deposit to 20% is that the LVR restrictions won’t apply to you, you won’t have to pay low equity fees, and you’ll be able to negotiate the best interest rates going.
