Guarantor mortgage scenario
Let's look at the process with an example guarantor scenario:
- Jai and Rahda purchase a $600,000 apartment with a 5% deposit ($30,000).
- They estimate their lenders mortgage insurance (LMI) premium using Finder's LMI calculator and are shocked to learn they'll need to pay $22,789.
- Rahda's parents own their home outright. They agree to guarantee a further 15% ($90,000) of the property cost. This eliminates the LMI cost completely.
- Jai and Rahda repay $100,000 of their loan principal over the next 5 years. Rahda's parents are no longer liable because the $90,000 they guaranteed has been repaid.

Hi
I went guarantor for my sons mortgage and now we want to sell our house and purchase a new house.
Can I transfer the guarantor amount to the new house? if not what do I need to do?
Hi Karen,
Thanks for your question.
Depending on the value of your new property, you can still transfer the guarantor amount to the new house.
The bank will need to reassess your son’s guarantor loan and may need to send a valuer to the new property at the mortgagor’s expense.
If you would like to discuss your options, please get in touch with your lender directly.
Cheers,

My son & partner are looking to purchase their first home, they are buying an established home , so therefore don’t qualify for first home loans grant.
The property is up for sale at $448,000 they have about $50,000 saved , but only want to use $30,000 as deposit. The realestate agent says they may get it for $430,000?? They have asked us to go as guarantor for them, but we already have 3 loans secured to our mortgage/home. Are we up for the short fall on the deposit or the cost of LMI?
I have read your article, but still unsure what to do??
Thanks,
Hi Lindy,
Thanks for your question.
If you agree to be guarantors, then your property will be used as security for the loan. If there is a shortfall on the deposit or cost of LMI, the equity in your property may be liable for this cost.
Please also note if the borrowers can not meet their loan obligations, this responsibility also falls on you. It might be a good idea to speak to a financial planner or the lender first to see if this is a viable option for you.
Cheers,
Shirley
Hi
Could you please advise if a guarantor is able to withdraw money from extra payments they have made or from the equity of their home whilst being a guarantor? Or do they have to wait until they are released from being a guarantor?
Hi Carol,
Thanks for your question.
This depends on the nature of your home loan and how much equity has been offered in the guarantee.
Please speak to your lender about this, they should be able to advise on what options are available.

My mum has decided to be guarantor for my brother and his wife’s home loan. The guarantee is limited to an amount (about $80,000) against Mum’s home which is nearly paid off.
My question is whether the guarantee will affect Mum’s ability to redraw on her mortgage. She uses this as a safety net as she has no super and lives on the pension, supplemented by self-employment.
Hi Alison,
Thanks for your question.
Your mum will need to speak to her lender about whether she can draw on her home loan as a guarantor.
It would depend on the lender and their policies, along with the type of loan your mum has and the amount of equity that is in her property.
Cheers,

I am in the process of buying my first home. I have been conditionally approved and have been informed that the contract of purchase has been through the vendor manager etc and is now on the way to the solicitor to be signed however they are still saying i need to wait for my guarantors 2nd mortgage applications needs to be approved before i have formal approval. What does a 2nd mortgage mean and what kind of things do they look for to approve it?
Hi Bonnie,
thanks for the question.
If your guarantor already has a mortgage on their property and elects to become a guarantor for a loan, this will be classified as a second mortgage. In Australia, any second mortgage being taken out on a property requires the permission of the first lender to be approved. They’ll take into account the employment, current debt, credit history and other factors when taking into account this approval.
Cheers,
Marc.
