Why a 10% Deposit Can Work for Your Home Loan

A 10% deposit can get you into your own home years earlier than waiting to save 20%.

The trade-off is Lenders Mortgage Insurance and slightly less negotiating room on your interest rate, but for many buyers, particularly those in secure professions, the cost of waiting often outweighs the cost of LMI. What matters most is understanding how lenders assess your application when you're borrowing more than 90% of the property value, and which loan features will still work in your favour even with a smaller deposit.

What Lenders Look at When You Apply with 10% Down

Lenders assess your income stability, existing debts, and how you've managed credit in the past. With a 10% deposit, they're lending you 90% of the property value, so they'll want to see genuine savings history and a clear repayment buffer. Medical professionals, accountants, and other salaried professionals often find this easier to demonstrate because their income is predictable and their employment is considered lower risk. You'll still need to show you can cover your repayments if interest rates rise, which is why lenders apply a serviceability buffer of around 3% above the actual rate you'll pay.

Consider a junior doctor purchasing an apartment close to the hospital. With a 10% deposit and steady income from a public health employer, the lender's main concern isn't job security but whether the repayments remain affordable if rates increase. The application included payslips, a letter confirming permanent employment, and three months of bank statements showing regular savings. The loan was approved at a variable rate with an offset account, which meant any future savings could reduce interest from day one.

Lenders Mortgage Insurance and How It's Calculated

LMI protects the lender if you default, and it's charged when your loan to value ratio exceeds 80%. The premium depends on your deposit size and loan amount. At 90% LVR, the cost is typically between 2% and 3% of the loan amount, though some lenders offer discounted LMI for specific professions. You can pay it upfront or add it to your loan amount, and most buyers choose the latter to preserve cash for settlement and immediate costs like furniture or minor repairs.

The premium is a one-off cost, not an ongoing fee. Once it's paid, you don't pay it again even if you refinance, provided your new loan amount doesn't push your LVR back above 80%. Some buyers assume LMI is wasted money, but if it means you're building equity in your own property rather than paying rent while saving another 10%, it often works out financially sound. We regularly see clients who bought with LMI three years ago now sitting on equity that far exceeds what they paid in insurance.

Which Home Loan Features Still Make Sense at 90% LVR

An offset account is one of the most useful features you can secure, even with a smaller deposit. Every dollar in the offset reduces the balance on which interest is calculated, and because you're borrowing a higher amount, the impact is proportionally larger. If you're putting $10,000 in an offset against a $450,000 loan, you're saving interest on that $10,000 without locking it away in the loan itself.

A split loan structure can also work well if you want some certainty around repayments but don't want to lock in your entire loan amount. You might fix 50% for three years at a known rate and leave the other 50% variable with an offset attached. That gives you stability on half your repayments and flexibility to make extra repayments or use your offset on the other half without penalty. Not every lender offers this at 90% LVR, but many do, and it's worth asking for.

Portability is another feature that matters if you think you might move within the first few years. A portable loan lets you transfer the same loan to a new property without refinancing, which can save on discharge fees and application costs. For professionals who might relocate for work or upgrade as their family grows, this removes one barrier to moving when the time is right.

Why Your Profession Can Influence Your Interest Rate

Some lenders offer rate discounts or waived LMI for specific occupations, particularly in healthcare, accounting, and legal fields. These aren't advertised on comparison sites, and they're not automatic. You need to apply through a channel that knows which lenders have these policies and how to structure your application to qualify. A 0.10% to 0.20% discount might not sound significant, but on a $450,000 loan over 30 years, it can mean several thousand dollars in saved interest.

In our experience, a pharmacist applying for an owner occupied home loan with a 10% deposit was able to access a lender that waived LMI entirely due to their profession. The loan amount was $495,000, and the LMI saving was just over $14,000. The same lender also offered a slightly lower rate than the client's own bank, and the loan included an offset account and unlimited additional repayments. Without knowing that lender's professional package existed, the client would have paid full LMI and a higher rate elsewhere.

Fixed or Variable Rate with a Smaller Deposit

Your deposit size doesn't limit your access to fixed or variable rate options. Both are available at 90% LVR, and your choice should depend on your income certainty and how you want to manage repayments over the next few years. A variable rate gives you flexibility to make extra repayments and use an offset, while a fixed rate locks in your repayment amount for a set period, usually between one and five years.

If your income is stable and you're likely to have surplus cash each month, a variable rate with an offset lets you reduce interest as you go. If your income varies or you prefer to know exactly what you'll pay each month, fixing part or all of your loan removes the uncertainty. You can also split your loan between fixed and variable, which is common among buyers who want some protection from rate rises but don't want to lose access to features like offset and extra repayments on the entire balance.

How Long It Takes to Build Equity with a 10% Deposit

Equity builds through two channels: your repayments and property value growth. With a principal and interest loan, every repayment reduces your loan balance slightly, and over time that adds up. In the first few years, most of your repayment goes toward interest, but even small reductions in the principal improve your equity position. If property values rise, your equity grows faster because you own a percentage of a more valuable asset.

After two years of regular repayments on a $450,000 loan, you might have paid down $15,000 in principal. If the property has increased in value by 5%, that's another $25,000 in equity, bringing your total equity to around $70,000 from an initial $50,000 deposit. Once your LVR drops below 80%, you can refinance without LMI, which opens up access to lenders with lower rates or features that weren't available when you first borrowed.

Should You Consider Interest-Only with a Small Deposit

Interest-only repayments can lower your monthly outgoings, but they don't build equity through repayments. You're only paying the interest charged each month, so your loan balance stays the same unless property values rise. This structure is more common with investment loans, where the interest is tax-deductible and the goal is often to maximise cash flow rather than pay down debt quickly.

For an owner occupied home loan, interest-only can make sense in specific situations, such as when you're expecting a pay rise or bonus within a year or two and want to keep repayments lower in the short term. But lenders are less willing to approve interest-only for owner-occupiers at 90% LVR because you're not reducing the loan balance, which increases their risk. If you do get approval, it's usually for a limited period, after which the loan reverts to principal and interest.

Applying for Pre-Approval Before You Start Looking

Pre-approval tells you how much you can borrow and locks in a rate for a set period, usually three to six months. It's not a guarantee, but it gives you confidence when you're making offers because you know a lender has already assessed your income, debts, and deposit. With a 10% deposit, pre-approval also identifies any issues early, such as insufficient genuine savings or credit file concerns, so you can address them before you find a property you want to buy.

The application process involves providing payslips, tax returns if you're self-employed, bank statements, and ID. The lender will also check your credit file and calculate your borrowing capacity based on your income and existing commitments. Once you have pre-approval, you can move quickly when the right property comes up, and sellers and agents take your offer more seriously because they know you've already been assessed by a lender.

What Happens When You Want to Refinance Later

Refinancing lets you switch lenders to access a lower rate, different features, or better loan terms. Once your equity reaches 20%, you can refinance without paying LMI again, and you'll have access to a wider range of lenders and rate discounts. Even before you hit 20% equity, refinancing can still make sense if another lender offers a significantly lower rate or waives LMI based on your profession.

The refinancing process is similar to your original application. The new lender will assess your income, debts, and the current property value, then offer a loan amount based on your equity and borrowing capacity. If you've been making extra repayments or property values have risen, you might find you can borrow more if needed, or simply secure a lower rate on your existing balance. For a detailed look at when and how to refinance, our refinancing page covers the timing and cost considerations.

Buying with a 10% deposit isn't about taking shortcuts. It's about starting sooner with a clear understanding of what you're paying for and how your loan will work over time.
