The deposit is rarely the only thing standing between you and settlement.
Most first home buyers in NSW know they need between 5% and 20% saved, but the surprise usually arrives when you add stamp duty, lender costs, conveyancing, and building inspection fees to the calculation. A buyer targeting a property at the current median in Sydney's outer suburbs can easily need an additional $15,000 to $25,000 beyond the deposit itself. That gap is where most applications stall.
Where the Deposit Calculation Falls Apart
You start with a deposit target. You save until you reach that number. Then you speak to a lender or broker and discover the deposit alone does not get you to the settlement table. Stamp duty is the largest additional cost. In NSW, first home buyers purchasing below $800,000 pay no transfer duty on established or new homes. Between $800,000 and $1,000,000, a sliding concession applies. Above $1,000,000, standard duty rates return. For vacant land, the full exemption applies up to $350,000, with concessions phasing out at $450,000.
Consider a buyer purchasing at $850,000. The property sits within the concession band, so partial duty applies. Add legal fees, pest and building reports, loan application fees, and mortgage registration, and you are committing another $8,000 to $12,000 depending on the lender and the property type. That amount needs to come from genuine savings or an acceptable non-borrowed source. It cannot be added to the loan in most cases.
Lenders Mortgage Insurance When You Borrow Above 80%
Lenders Mortgage Insurance protects the lender if you default and the property sells for less than the outstanding loan balance. It does not protect you. The premium is calculated as a percentage of the loan amount and varies based on your deposit size and the lender's risk assessment. A 5% deposit attracts higher LMI than a 10% deposit. A 10% deposit attracts higher LMI than 15%. At 20% or more, LMI does not apply.
Under the Australian Government 5% Deposit Scheme, eligible first home buyers can purchase with a 5% deposit and avoid paying LMI. Housing Australia guarantees the portion of the loan between your deposit and 20% of the property value. The scheme has no income caps and no annual place limits. It operates through a panel of 31 participating lenders, including three major banks and 28 non-major lenders. You cannot apply directly to Housing Australia. The application is made through your broker or lender during the standard home loan application process. Property price caps apply. In Sydney, the cap sits at $1,500,000. In regional NSW, separate caps apply depending on the area.
Without access to that scheme, a borrower with a 5% deposit would typically pay LMI in the range of $10,000 to $30,000 depending on the loan size and lender. That premium is usually added to the loan amount rather than paid upfront, but it still increases your total borrowing and your repayments.

Gift Deposits and How Lenders Treat Them
A monetary gift from a parent or immediate family member is an acceptable deposit source for most lenders. The gift must be declared. The lender will request a signed gift letter confirming the funds are not a loan and do not need to be repaid. Some lenders require the donor to provide identification and proof of where the gifted funds originated. The stricter lenders will ask for bank statements showing the donor held those funds for at least three months before transferring them to you.
Gifts can make up part or all of your deposit, but they do not reduce the LMI calculation unless your total deposit, including the gift, reaches 20% or more. A buyer with a 3% deposit from savings and a 7% deposit from a parental gift has a 10% deposit overall. LMI is calculated on a 10% deposit, not a 3% deposit. That distinction matters because the premium drops meaningfully between 5% and 10%, and again between 10% and 15%.
If your family is willing to provide direct security rather than cash, a parental guarantee loan may allow you to borrow with little or no cash deposit by using equity in your parents' property as additional security. The structure varies between lenders, and the guarantor takes on contingent liability, so it requires careful discussion and independent legal advice for all parties.
First Home Owner Grants and How They Apply in NSW
The First Home Owner Grant in NSW pays $10,000 for eligible purchases of new homes or substantially renovated homes. The grant does not apply to established properties. To qualify, the purchase price must not exceed $600,000, or for land and build contracts, the combined value must not exceed $750,000. You must be a natural person aged 18 or over, an Australian citizen or permanent resident, and you must not have previously received a first home owner grant in any Australian state or territory. You must also not have previously owned residential property in Australia, whether alone or jointly.
The grant can be used toward your deposit or settlement costs. It is paid after settlement, not before, so you cannot rely on it to reach your minimum deposit unless your lender agrees to take the grant into account when assessing your application. Some lenders will, but most will not. In practice, the $10,000 is more commonly used to cover upfront costs like conveyancing, building inspections, or initial loan payments rather than forming part of the deposit calculation.
The Pre-Approval Window and Why It Closes
Pre-approval is valid for between 90 and 120 days depending on the lender. During that window, the lender has assessed your income, liabilities, expenses, and deposit, and confirmed in principle that they will lend you a specified amount. The approval is conditional. It assumes your financial position does not change. If you change jobs, take on new debt, or your income drops, the pre-approval may be withdrawn or reassessed.
In our experience, the most common reason a pre-approval lapses is that buyers underestimate how long it takes to find a property they want to purchase. Three months feels sufficient when you begin searching. It rarely is, particularly in areas where stock is limited or where buyers are competing for a narrow band of properties within a specific price range. When the pre-approval expires, you need to reapply. If interest rates have moved or if the lender's serviceability calculation has changed, your borrowing capacity may be lower the second time.
A separate issue arises when a buyer secures pre-approval and then waits too long to make an offer. If rates rise or if the lender tightens its assessment policies, the final loan approval at contract stage may not match the pre-approval figure. That gap can force a buyer to renegotiate the purchase price, increase their deposit, or withdraw from the contract entirely.
Fixed Versus Variable Rates and the Offset Trade-Off
A fixed interest rate locks your repayment amount for a set period, typically between one and five years. You are protected from rate rises during that period, but you also do not benefit if rates fall. Most fixed rate loans do not offer an offset account. Some offer a redraw facility, but withdrawals may be restricted or subject to lender approval. If you break a fixed rate loan early, you may be charged break costs calculated on the difference between your fixed rate and the lender's current cost of funds.
A variable interest rate moves with the market. Your repayments can rise or fall depending on rate changes by the Reserve Bank and your lender's margin. Most variable rate loans offer an offset account, which is a transaction account linked to your loan. The balance in the offset account reduces the loan balance on which interest is calculated. If you have a $500,000 loan and $20,000 in your offset account, you pay interest on $480,000. The offset balance is fully accessible. You can deposit and withdraw without restriction.
For first home buyers who expect irregular income, plan to use government co-contribution schemes like the First Home Super Saver Scheme, or want the flexibility to park savings and reduce interest without locking funds away, a variable rate loan with an offset account is usually the better structure. For buyers who value certainty and do not expect to hold surplus cash during the fixed period, a fixed rate can provide short-term repayment stability.
When Your Borrowing Capacity Does Not Match Your Budget
Your borrowing capacity is determined by your income, your existing liabilities, your living expenses, and the lender's assessment rate. The assessment rate is the interest rate the lender uses to test whether you can afford the loan. It is usually higher than the actual interest rate you will pay. Lenders apply a buffer of around 3% above the loan rate to ensure you can still make repayments if rates rise.
A borrower earning $90,000 per year with no dependents and minimal liabilities may be assessed as able to service a loan of around $500,000 to $550,000 depending on the lender's policy and current rates. If that borrower has a car loan, a personal loan, or a buy-now-pay-later account with an outstanding balance, the figure drops. If they have claimed significant work-related deductions on their tax return, reducing their taxable income, some lenders will assess them on the lower taxable figure rather than gross income. That can reduce capacity by $50,000 or more.
In a scenario like this, the buyer has three options. First, pay down or close the non-mortgage debts before applying. Second, increase income by adding a co-borrower or demonstrating additional income streams that the lender will accept. Third, adjust the property budget to match the assessed capacity rather than the preferred price range. None of those options are immediate, which is why borrowing capacity discussions belong at the start of the process, not after you have made an offer.

Frequently Asked Questions
Can I use a gifted deposit from my parents to buy my first home in NSW?
A monetary gift from a parent or immediate family member is an acceptable deposit source for most lenders. The gift must be declared, and the lender will request a signed letter confirming the funds are not a loan and do not need to be repaid. Some lenders require proof of where the gifted funds originated.
Do I pay Lenders Mortgage Insurance if I use the Australian Government 5% Deposit Scheme?
No LMI is payable under the Australian Government 5% Deposit Scheme. Housing Australia guarantees the portion of the loan between your deposit and 20% of the property value. Applications are made through a participating lender, not directly to Housing Australia.
How long does pre-approval last and what happens if it expires?
Pre-approval is valid for between 90 and 120 days depending on the lender. If it expires, you need to reapply. If interest rates have moved or the lender's serviceability calculation has changed, your borrowing capacity may be lower the second time.
What is the First Home Owner Grant in NSW and when does it apply?
The NSW First Home Owner Grant pays $10,000 for new homes or substantially renovated homes only, not established properties. The purchase price must not exceed $600,000, or $750,000 for land and build contracts. The grant is paid after settlement, not before.
Should I choose a fixed or variable interest rate for my first home loan?
A variable rate with an offset account provides flexibility to reduce interest while keeping funds accessible. A fixed rate locks repayments for a set period but usually does not offer an offset account and may carry break costs if you exit early. The right choice depends on your income pattern and whether you expect to hold surplus cash.
