When do I need a mortgage guarantee?
Banks usually require a collateral for your entire loan amount. The home that you purchase will qualify as collateral up to 70-75% of its fair value. A guarantee is needed, when the required loan amount of exceeds the collateral value and the borrower does not have additional collateral or savings available to satisfy this need.
By utilising a guarantee, the home buyer can also draw a larger loan and leave any savings and investments untouched for a rainy day.
