What Is a Guarantor Loan?

Parents use the equity in their property as additional security for their child's home loan. This can help avoid LMI or purchase with a smaller deposit.

Risks for Parents

  • If your child defaults, the bank can require you to pay
  • The guarantee affects your borrowing capacity
  • If property values fall, you may be liable longer

Releasing the Guarantee

Typically released when the loan-to-value ratio drops below 80% through repayments and property growth, usually 2-5 years.
