Getting Your Deposit Together Without Waiting Years
You can enter the property market with as little as a 5% deposit if you meet the criteria for certain government schemes, though most borrowers still need 20% to avoid paying LMI. The Australian Government 5% Deposit Scheme lets eligible first home buyers purchase with just 5% down, while Housing Australia guarantees the difference up to 20%. No income caps apply, and the scheme works through participating lenders who assess your application alongside the standard loan approval.
Consider someone purchasing their first property using the 5% scheme. They've saved around 5% of the property value and meet the lender's serviceability requirements at current variable rates plus the 3% buffer that every bank must apply. The guarantee covers the gap, so they avoid LMI entirely. The trade-off is that property price caps apply depending on location, and you'll need to work with one of the lenders on the Housing Australia panel. For someone who's been saving steadily but doesn't want to wait another two years to hit 20%, the scheme can bring forward a purchase by a significant margin.
Genuine savings matter more than most buyers expect. Lenders want to see that your deposit has been held in your account for at least three months and hasn't simply been gifted or borrowed in the days before application. Funds from the sale of assets, tax refunds, or bonuses can count, but the key is demonstrating a consistent savings pattern. If you're relying on a family guarantee instead, the guarantor's equity in their own property substitutes for part of your deposit, though that brings its own considerations around future refinancing and releasing the guarantee once you've built enough equity.
How Loan Structure Affects Your Wealth-Building Strategy
Splitting your loan between fixed and variable rates gives you partial certainty on repayments while keeping access to features like an offset account on the variable portion. Most lenders let you split in any proportion, though common approaches include 50/50 or a 70/30 split favouring either fixed or variable depending on your rate outlook and cash flow needs. The variable portion typically allows unlimited extra repayments and redraw, while the fixed portion locks in your rate but limits flexibility.
In our experience, buyers focused on building equity quickly tend to favour a higher variable portion because they want the ability to throw extra repayments at the loan whenever they have surplus income. The fixed portion acts as a buffer, ensuring part of the repayment stays predictable even if rates climb. The offset account linked to the variable portion then becomes a cash management tool, letting you park savings, salary, and bonuses in an account that reduces the interest charged on your loan without locking those funds away.
An owner occupied home loan structured with an offset can accelerate equity growth in a way that a standard loan without one can't match. Every dollar sitting in the offset reduces your loan balance for interest calculation purposes. If you have a variable loan amount of $400,000 and $30,000 in your offset, you're only paying interest on $370,000. That difference compounds over time, and you're not sacrificing access to your cash if you need it for an emergency or an opportunity.
Understanding Serviceability and How It Limits Your Borrowing
Every lender must assess your ability to repay at a rate at least 3% higher than the actual loan product rate, a rule enforced by APRA since October 2021. That buffer means if you're applying for a variable rate loan sitting around current market levels, the bank is testing whether you can still afford the repayments if that rate jumps by 3 percentage points. Your income, existing debts, living expenses, and dependents all feed into that calculation, and the result determines your maximum borrowing capacity.
The DTI lending limit that came into effect in February 2026 adds another layer. Lenders can only write up to 20% of their new owner-occupier loans to borrowers with a total debt level of six times their annual income or higher. If your income is $100,000 and you're trying to borrow $650,000, your DTI ratio is 6.5, which puts you in the restricted bucket. The lender might still approve the loan, but it counts against their quarterly limit, so some institutions are more cautious about high-DTI applications than others.
If you're purchasing as a first home buyer and your borrowing capacity is sitting right on the edge of what you need, small changes make a difference. Paying down a car loan or credit card before applying can lift your serviceability by more than you'd expect. Even reducing credit card limits on accounts you're not using frees up capacity, because lenders assess the full available limit, not just what you owe.
When Help to Buy Makes Sense and When It Doesn't
Help to Buy lets the Australian Government take an equity stake of up to 40% on a new home or 30% on an existing home in exchange for contributing that percentage of the purchase price. You need a minimum 2% deposit, and income limits apply: $103,000 for individuals and $165,000 for joint applicants from 1 July 2026. The scheme targets buyers who can service a loan but struggle to save a large deposit, and it reduces the loan amount you need to borrow, which can bring the repayments within reach.
The key consideration is that the government's equity share grows with the property's value. If you purchase with a 30% government contribution and the property appreciates by 20%, the government's share of that gain is also 30%. When you sell or refinance to buy out the government's stake, you'll pay 30% of the current market value, not 30% of what you originally paid. That can work in your favour if the property underperforms, but it reduces your upside if you're in a growth area.
Help to Buy works through participating lenders and can't be combined with the 5% Deposit Scheme, though you can generally use it alongside state stamp duty concessions. For someone earning just under the income threshold with a small deposit, the scheme might be the only way to enter the market in the near term. For someone who can save a larger deposit or access a family guarantee, a standard loan structure might make more sense from a wealth-building perspective.
Choosing Between Principal and Interest or Interest-Only Repayments
Principal and interest repayments reduce your loan balance every month, building equity automatically as you pay down both the interest charged and a portion of the original loan amount. Interest-only repayments cover just the interest, keeping your repayments lower in the short term but leaving your loan balance unchanged. Most investment loans offer an interest-only period of up to five years, though some lenders extend that depending on your LVR and financial profile.
For an owner-occupied property, lenders generally expect principal and interest repayments unless there's a specific reason for an interest-only structure, such as upcoming changes to your income or plans to sell within a few years. For wealth-focused buyers, principal and interest makes sense on your home because you're not claiming a tax deduction on the interest anyway, and reducing your debt faster improves your equity position for future purchases.
The trade-off comes down to cash flow and opportunity cost. If you're confident you can invest the difference between interest-only and principal and interest repayments at a return higher than your loan rate, an interest-only period might suit your strategy. But that requires discipline and a clear plan, and most buyers find that the forced savings aspect of principal and interest repayments works in their favour over time.
What Lenders Actually Look for in Your Application
Your credit file, employment history, savings pattern, and existing liabilities all shape how lenders assess your application, but the single most important factor is serviceability. If the numbers don't stack up under the 3% buffer, the loan won't proceed regardless of how strong the rest of your profile looks. Lenders verify your income through payslips, tax returns, and employer confirmation, and they'll ask for bank statements covering at least three months to review your spending habits and confirm your declared living expenses.
Unexplained deposits, frequent overdrafts, or patterns of gambling transactions can raise questions during the assessment. Lenders aren't looking to judge your lifestyle, but they need confidence that you can manage your finances consistently. If you've recently changed jobs, some lenders require you to pass probation before they'll assess the new income, while others accept an employment contract if you're moving within the same industry at a similar or higher salary level.
For buyers applying through a broker, the advantage is that we can match your profile to lenders who are more likely to approve your specific situation. One lender might decline an application based on casual employment, while another has a policy that accepts casual income if you've been with the same employer for 12 months or more. That knowledge saves time and avoids multiple credit enquiries that can impact your credit file.
Managing Stamp Duty and Upfront Costs Alongside Your Deposit
Stamp duty concessions vary by state, and in New South Wales, first home buyers purchasing an established property valued up to $800,000 pay no transfer duty at all. A sliding concession applies between $800,000 and $1,000,000, phasing out completely at the top end. On vacant land, full exemption applies up to $350,000, with a concession extending to $450,000. Those concessions reduce the cash you need at settlement, but you still need to budget for legal fees, building and pest inspections, loan establishment fees, and any lender or government charges.
For someone purchasing in Parramatta at a price point under $800,000, the stamp duty saving can be $30,000 or more compared to what a non-first-home buyer would pay. That's cash that can stay in your offset account or go toward furniture and moving costs rather than disappearing into a government charge. The catch is that you need to meet the eligibility requirements, which include not having owned property before and intending to occupy the property as your principal place of residence.
If you're considering a purchase in Auburn, Merrylands, or Granville, the same concessions apply, and property values in those areas often sit within the range where the full exemption kicks in. For buyers focused on building equity in Western Sydney, the combination of lower entry prices and nil stamp duty creates a strong starting point for long-term wealth accumulation through property.
Knowing When to Lock in a Fixed Rate and When to Stay Variable
Fixed rates give you certainty for one to five years, with your repayments locked regardless of what happens to the Reserve Bank cash rate or market conditions. Variable rates move with the market, which means your repayments can rise or fall, but you retain flexibility to make extra repayments, access redraw, and link an offset account. The decision comes down to your risk tolerance, cash flow predictability, and rate outlook.
If you're fixing and rates drop, you'll be stuck paying the higher fixed rate unless you're willing to pay break costs to exit early. Those costs can run into thousands of dollars depending on how far rates have fallen and how much time remains on your fixed term. If you're on a variable rate and rates climb, your repayments increase, which can strain your budget if you haven't built in a buffer.
A split structure hedges the risk. You lock in part of your loan for certainty and keep part variable for flexibility. If rates fall, you're only locked in on a portion. If rates rise, you've protected part of your repayment from the increase. That middle path works well for buyers who want some predictability without giving up the features that help accelerate equity growth.

Frequently Asked Questions
Can I buy a property with less than a 20% deposit?
Yes, you can purchase with as little as 5% under the Australian Government 5% Deposit Scheme if you meet the eligibility criteria and work with a participating lender. Without the scheme, most lenders will require you to pay LMI if your deposit is below 20%.
What is the serviceability buffer and how does it affect my borrowing?
The serviceability buffer requires lenders to assess your ability to repay at a rate at least 3% higher than the actual loan rate. This reduces your maximum borrowing capacity compared to what you could afford at the advertised rate, ensuring you can still manage repayments if rates rise.
Should I choose a fixed rate, variable rate, or split loan?
A variable rate offers flexibility with offset accounts and unlimited extra repayments, while a fixed rate locks in certainty for one to five years. A split loan combines both, giving you partial protection from rate rises while maintaining access to features that help build equity faster.
How does Help to Buy work and should I use it?
Help to Buy allows the Australian Government to contribute up to 40% of the purchase price for a new home or 30% for an existing home in exchange for an equivalent equity share. The government's share grows with the property's value, so you'll repay based on the market value when you sell or refinance, not the original purchase price.
What stamp duty concessions apply for first home buyers in New South Wales?
First home buyers in New South Wales pay no transfer duty on properties valued up to $800,000, with a concession that phases out at $1,000,000. On vacant land, a full exemption applies up to $350,000 with a concession extending to $450,000.
