Saving a full 20 per cent deposit is the hurdle most first home buyers in Newcastle run into. Buy with less, and most lenders add a cost called Lenders Mortgage Insurance. It can add thousands to your purchase, and plenty of buyers only hear about it once the loan is being assessed. The good news is that paying it is not inevitable.
Here’s what LMI is, who it actually protects, roughly what it costs, and the four practical ways to avoid or reduce it.
What LMI is, and who it protects
Lenders Mortgage Insurance is a one-off premium you pay, but the cover is not yours. It protects the lender. If a borrower defaults and the property sells for less than the loan balance, the insurer pays the lender’s shortfall. It is not mortgage protection insurance, and it is not income protection: neither your repayments nor your income are covered.
One detail worth knowing: after the insurer pays the lender, it can come after the borrower to recover that money. LMI does not wipe your debt.
Whether you pay it comes down to your loan-to-value ratio (LVR) — the loan as a percentage of the lender’s valuation. Borrow $760,000 against an $800,000 property and your LVR is 95 per cent. Above 80 per cent, most lenders require LMI, though the threshold and the premium vary by lender, property type and your circumstances.
What it costs, and how it is paid
There is no standard price. The premium rises steeply with both the loan size and the LVR, and each lender uses its own insurer. As a rough guide, a 90 per cent LVR loan on a mid-priced home often runs to several thousand dollars, while a 95 per cent LVR loan on an $800,000 purchase can exceed $30,000. Treat those as indicative only — the sole way to know your figure is a quote from the lender assessing your loan.
You can pay the premium at settlement, or add it to the loan. Adding it (capitalising) is more common, because it keeps cash in your pocket, but it costs more over time. Capitalise a $20,000 premium into a $760,000 loan at 6 per cent over 30 years and you add about $120 a month, around $23,200 in interest, and roughly $43,200 repaid in total for that $20,000. Our loan repayment calculator will show the difference on your own numbers.
Option 1: Save a 20 per cent deposit
The direct route. At 80 per cent LVR or below, most lenders drop the LMI requirement, and you get a smaller loan, lower repayments, less interest and usually a sharper rate.
The trade-off is time, and you pay rent while you save. On the Newcastle and Lake Macquarie median house, a 20 per cent deposit is a long campaign, which is why most first home buyers I work with look at the options below. If you do keep saving, remember the deposit is a spectrum rather than a pass or fail: moving from 5 to 10 or 15 per cent can cut the premium substantially and improve your rate.
Option 2: The Australian Government 5% Deposit Scheme
This is the option that has changed most, and older articles will tell you the wrong thing. It was formerly the Home Guarantee Scheme, and since 1 October 2025 it has had no income caps, no waitlists and no Lenders Mortgage Insurance.
Eligible first home buyers can buy with a 5 per cent deposit (2 per cent for single parents and legal guardians), and Housing Australia guarantees part of the loan so the lender does not require LMI. It is a guarantee, not a payment: you still borrow and repay the full amount.
To qualify you must be an Australian citizen or permanent resident aged 18 or over, buying to live in the home, and either a first home buyer or someone who has not owned property in Australia in the last 10 years. Price caps apply, and the local detail matters: Newcastle and Lake Macquarie are listed regional centres, so the cap here is $1.5 million, against $800,000 across much of the rest of regional NSW. You apply through a participating lender and still have to pass its normal credit and serviceability checks.
We compare the routes side by side in 5% scheme vs guarantor vs a 20% deposit, and cover the cap in what the $1.5 million cap means locally.
Option 3: A family guarantee
A parent or close family member offers equity in their own property as extra security, usually enough to bring your LVR to 80 per cent, which removes the LMI requirement. With a 5 per cent deposit, the guarantee typically covers about 15 per cent of the price. No money changes hands.
The risk sits with the guarantor: if the loan defaults, they are liable for the guaranteed portion, and their property is on the line. Lenders require guarantors to get independent legal advice first, and ASIC’s Moneysmart sets out those risks plainly. Our guide to who can be a guarantor covers the equity test, and how a guarantee is released explains the exit.
Option 4: A professional LMI waiver
Some lenders waive LMI for particular occupations, even under a 20 per cent deposit. It is most common for medical practitioners, dentists, veterinarians, lawyers and accountants, and some lenders extend it to engineers or actuaries. Eligible occupations are lender-specific.
Working in one of those fields is not enough on its own. Lenders usually want proof of registration with a professional body, a minimum income, and a clean credit history, and the waiver is generally capped around 90 per cent LVR — so a 10 per cent deposit may qualify where 5 per cent will not.
Weigh the whole package rather than the waiver alone. A waiver loan with a higher rate can cost more over time than a standard loan with the premium capitalised.
Three things buyers get caught by
The valuation, not the price. Lenders lend against their own valuation. Agree to pay $800,000 on a property that values at $770,000 and a planned $760,000 loan is suddenly a 98.7 per cent LVR, which means a bigger premium or a smaller loan and more cash needed.
Avoiding LMI is not automatically the cheaper path. Buying with a 5 per cent deposit avoids the premium but leaves a larger loan and very little equity, which is uncomfortable if values fall. Compare the total cost of each route.
The deposit is not your only cash. Budget for stamp duty (or check your first home buyer duty exemption), legal fees, building and pest inspections and loan fees, and keep a buffer after settlement.
Frequently Asked Questions
Can I get LMI refunded if I sell or refinance early?
Some insurers offer a partial refund if the loan is discharged within the first year or two, but many do not, and the amount is small. Treat the premium as a sunk cost rather than something you will get back, and ask the lender for its refund policy before you sign.
Does LMI protect me if I lose my job?
No. LMI covers the lender’s loss if you default and the property sells for less than you owe. If you want cover for your own repayments, that is a different product — mortgage protection or income protection insurance, bought separately.
Is it better to pay LMI or wait and save a bigger deposit?
It depends on what prices do while you save, and on what you are paying in rent. Waiting can mean a larger deposit for the same home. The useful comparison is the premium against your likely rent and price movement over the same period, which is something we can model with you.
Do I pay LMI with the 5% Deposit Scheme?
No. Under the Australian Government 5% Deposit Scheme, Housing Australia guarantees part of your loan, so an eligible buyer purchases with a 5 per cent deposit and no Lenders Mortgage Insurance. You still borrow and repay the full loan amount.
Where to start
LMI is a real cost, but it is not always compulsory, and it is not always the wrong choice. Which route suits you depends on your deposit, your occupation, whether family help is on the table, and the price bracket you are buying in.
If you would like to work out whether you qualify for the 5% Deposit Scheme, what a premium would look like at your deposit level, or whether a guarantee makes sense, that is what we do every week for buyers across Newcastle, Lake Macquarie and the Hunter.
