How a low deposit loan can end up more expensive
Here's a simple example of 2 home loans with identical interest rates based on a $800,000 property and a 30-year loan term. The only difference is the deposit size. You can see how this changes both the loan amount (and therefore the repayments) and the LMI premium.
| Details | Low deposit | Full deposit |
|---|---|---|
| Property value | $800,000 | $800,000 |
| Deposit size | $40,000 (5%) | $160,000 (20%) |
| Loan amount | $760,000 | $640,000 |
| LMI costs | $34,982.80 | $0 |
| Interest rate (30-year loan) | 6.00% | 6.00% |
| Monthly repayments | $4,557 | $3,838 |
| Difference in monthly repayments | $719 more | $719 less |
In this hypothetical example, the low deposit borrower pays $34,982.80 in LMI premiums upfront, and an extra $719 a month in repayments. This is because they have to borrow more money.
Over the life of the loan this adds up to $139,006 in extra interest. Adding the LMI in, the low deposit home loan works out to be $173,988.80 more expensive.
But that doesn't mean the low deposit option is a bad idea
Choosing a low deposit home loan can still be worth it. You just need to have a clear idea of the costs involved. Plus, you can always minimise the interest charges over time by repaying more of the loan, or saving money in an offset account.
You also need to consider how long it would take you to save a 20% deposit. It could take you years.




Tighten up your spending
We are over 55 and looking to buy our first home, however we do not have a deposit at this stage and have about $50000 in debt and paying off some of the smaller debts and have no defaults. My husband has been in the same job for 8 yrs and I work casual.
Would we be considered by any lender for a mortgage
Hi Pauline,
thanks for the question.
Unfortunately Australian lenders will generally require a deposit of at least 5% of the property’s value for a borrower to qualify for a home loan, unless the borrower has a guarantor who can use the equity in their property to guarantee the deposit or a portion of it for the borrowers.
I hope this helps,
Marc.
daughter has ability to quickly repay mortgage of $185,000 at weekly repayments of $250 but only has $6000 savings towards deposit. What does she do
Hi Rebecca,
Thanks for your enquiry.
On this page, you can compare a range of lenders that offer the ability to borrow 95% loan to value ratio (LVR).
Your daughter might be interested to learn more about guarantor loans which could help with her deposit.
It is also advisable that she speaks with a mortgage broker to discuss her options.
Thanks,
Belinda
