A no-LMI loan sounds appealing to say the least. One of the key upfront costs of getting a loan is LMI, which can amount to thousands of dollars depending on the size of the loan and deposit. So when a lender says you can skip it, it’s easy to say yes and move on.
But most no-LMI loans come with slightly higher interest rates, and over a 25–30 year loan, that difference adds up. The less deposit you pay today, the more you will be paying every month. Whether that’s ideal for you completely depends on your financial situation.
If you are at that point where you have to choose between a higher interest rate (no-LMI loan) or 20% Deposit, this guide is for you. With us, explore both options and be sure to make an informed decision in your mortgage journey.
Understanding the Opportunity Cost of Both
No matter which direction you take, there would be a trade-off. You would either be paying more upfront, or you would be paying more over time.
Waiting for a 20% Deposit
Let’s start with the traditional path.
A 20% deposit on a $700,000 property means you need $140,000, not including stamp duty and other costs. For many buyers, that’s years of saving.
Now here’s where it gets tricky. Over the past decade, Australian property prices have generally trended upward. Even with short dips, the long-term pattern holds. In cities like Sydney and Melbourne, there have been periods where prices rose 5–10% annually. That’s not guaranteed, but it’s not rare either.
So if you spend, say, 3–4 years saving an extra $40,000–$60,000, there’s a fair chance the property you were aiming for has also gone up in value.
You might notice this yourself if you’ve been watching listings for a while. What felt achievable two years ago suddenly sits just out of reach.
That’s the opportunity cost here:
- You delay entering the market
- You risk paying more for the same property later
- You miss out on any capital growth during that time
There’s also the lifestyle side. Renting for longer, dealing with rent increases, and having less control over your living situation. That part doesn’t show up in spreadsheets, but it matters.
Taking a No-LMI Loan (and Paying a Higher Rate)
On the flip side, a no-LMI loan lets you get in sooner, often with a smaller deposit. That can be useful, especially if your income is strong but your savings haven’t caught up yet.
But you’re usually paying for that flexibility through your interest rate.
Let’s run a rough example.
- Loan: $600,000
- Term: 30 years
If your rate is 0.50% higher than a standard loan, that doesn’t look huge on paper but over time, it adds up.
You could be paying $150–$200 extra per month, depending on the exact rate and structure. Over 30 years, that can translate to $50,000–$70,000+ in additional interest.
That’s well above what LMI might have cost upfront. Now, not everyone keeps a loan for 30 years. Many refinance, upgrade, or sell within 5–10 years. So in some cases, the extra interest paid might actually be less than the LMI you avoided.
This is where it gets less black-and-white.
LMI Isn’t Always “Dead Money”
You’ll often hear LMI described as a sunk cost. That’s not entirely wrong, but it’s also a bit oversimplified.
LMI doesn’t benefit you directly, but it does buy you earlier access to the market.
For example:
- You buy a property with a 10% deposit and pay $20,000 in LMI
- The property grows by 5% per year (again, not guaranteed, but reasonable in many markets)
On a $700,000 property, that’s $35,000 in growth in the first year alone.
So even after accounting for LMI, you’re ahead on paper.
Of course, markets don’t move in straight lines. Some years are flat, some dip, but over longer periods, property has historically trended upward in Australia.
So the question becomes:
Would you rather pay LMI and get in sooner, or avoid it and risk higher entry prices later?
When a Higher Rate Might Make Sense
There are situations where a no-LMI loan can work in your favour.
You might lean this way if:
- Your income is strong and growing
- You expect to refinance within a few years
- You’re buying in an area with solid growth potential
- You don’t want to drain all your savings into a deposit
For example, some professionals (like doctors, lawyers, or certain essential workers) can access lender policies that waive LMI. In those cases, even with a slightly higher rate, the maths will still stack up. Some banks won’t even charge a rate premium for LMI waiver loans for Doctors and Lawyers.
Also, if you’re planning to upgrade in 5–7 years, the long-term interest cost becomes less relevant. You’re not holding the loan for the full 30-year period.
When Waiting for 20% Might Be the Safer Move
On the other hand, holding out for a 20% deposit tends to suit borrowers who want stability and predictability.
This might be you if:
- You prefer lower monthly repayments
- You’re planning to hold the property long-term
- Your budget is already tight
- You want access to better loan features and rates
A lower interest rate gives you more breathing room. That matters if rates rise, or if your circumstances change. Also, with a larger deposit, you start with more equity. That can make refinancing easier later and reduce your overall risk.
A Quick Side-by-Side Reality Check
Let’s keep this simple.
Option 1: Pay LMI
- Higher upfront cost
- Lower interest rate
- Enter the market sooner
- Potential for earlier capital growth
Option 2: No LMI, Higher Rate
- Lower upfront cost
- Higher ongoing repayments
- More flexibility early on
- Potentially higher total interest
There’s no clean winner here. It depends on timing, market conditions, and your own finances.
So, Which One Is Better?
There isn’t a universal answer. If there were, lenders wouldn’t offer multiple pathways.
In most cases, it comes down to this:
- If getting into the market sooner puts you in a stronger position overall, paying LMI or accepting a higher rate can make sense
- If stability and lower long-term costs matter more, aiming for a 20% deposit is usually the safer route
The key is running the numbers properly for your situation. Not just the headline costs, but how things look over 5, 10, even 15 years.
Final Thoughts
A no-LMI loan isn’t automatically better, nor is waiting for a 20% deposit. Both options come with trade-offs that aren’t always obvious at first glance.
If you’re weighing these choices right now, it’s worth stepping back and asking:
- How long am I likely to keep this loan?
- What happens if rates change?
- Am I buying for the short term, or settling in for the long haul?
