If your deposit is under 20%, there’s a good chance Lenders Mortgage Insurance (LMI) is about to become the single biggest extra cost in your purchase — sometimes tens of thousands of dollars, added straight onto your loan. Here’s what LMI actually is, what it tends to cost in 2026, and the main ways North Shore buyers can reduce or avoid it altogether.
What is LMI, and why does the bank want it?
Lenders Mortgage Insurance protects the lender, not you, if you default and the sale of the property doesn’t cover the loan. Most lenders require it whenever your loan-to-value ratio (LVR) is above 80% — in other words, whenever your deposit is smaller than 20% of the purchase price. It’s a one-off premium, usually capitalised onto the loan (added to what you borrow and repaid over the loan term, with interest), and it is not refundable if you refinance or pay the loan out early.
How much does LMI actually cost?
The premium is calculated on your loan amount and your LVR — the smaller your deposit, the higher the percentage. As a guide, on an owner-occupier loan over a typical 30-year term:
- On a $600,000 loan at 90% LVR (10% deposit), LMI is roughly $9,800–$10,000
- On the same loan at 95% LVR (5% deposit), LMI can climb to around $31,000
- On an $800,000 loan at 90% LVR, LMI is typically in the order of $14,000–$15,000, rising to over $40,000 at 95% LVR
These are indicative figures only — every insurer prices differently, and investment loans generally cost more than owner-occupier loans. A broker can get you an exact quote from each lender’s calculator before you commit.
Ways to reduce or avoid it
There are several legitimate paths around LMI, and which one suits you depends on your deposit, your profession and your family situation:
- Get to 20% deposit. The simplest fix — no LMI applies above an 80% LVR.
- Family guarantee (guarantor loan). A parent offers equity in their own home as additional security, which can take your effective LVR under 80% without a bigger cash deposit.
- Professional LMI waivers. Several major lenders waive LMI up to 90–95% LVR for eligible professionals — typically doctors, dentists, vets, lawyers, accountants, engineers and some nurses and allied health workers, usually subject to a minimum income. If you’re in one of these professions, it’s always worth checking before you assume LMI is unavoidable.
- Genuine savings and lender selection. LMI providers and pricing differ from lender to lender for the same LVR, so which bank you apply with can genuinely change the premium.
A quick note on 2026’s lending environment
It’s also worth knowing the broader backdrop: APRA’s new debt-to-income limit came into effect on 1 February 2026, capping the share of new lending banks can write above six times a borrower’s income at 20%, assessed separately for owner-occupiers and investors. It doesn’t affect most buyers, but combined with the RBA holding the cash rate at 4.35% through August 2026, lenders are being a little more deliberate about how they assess higher-LVR, higher-DTI applications — another reason it pays to compare more than one lender rather than assume your regular bank offers the best LMI or servicing outcome.
