Beginner's Guide to First Home Buyer Mistakes

Most first home buyers in Sydney lose money or delay settlement because they misunderstand how government schemes interact with deposit structures and duty concessions.

Applying for Pre-Approval Without Knowing Your Full Borrowing Capacity

Pre-approval tells you what a lender will offer, but it does not tell you what you can afford to repay or how much deposit you actually need. A buyer who applies for pre-approval without calculating their ongoing repayments, offset needs, and buffer requirements often finds themselves committed to a loan structure that does not suit their cash flow. The lender assesses your application using serviceability buffers and debt-to-income ratios that may approve you for a larger loan than you can comfortably manage.

Consider a buyer who receives pre-approval for $850,000 with a 5% deposit under the Australian Government 5% Deposit Scheme. The approval is valid, but the buyer has not accounted for ongoing strata fees, council rates, or the fact that their variable interest rate could rise. Six months after settlement, they are managing repayments but have no buffer for rate movements or emergency costs. The loan was affordable on paper but tight in practice.

Understanding your borrowing capacity before you apply means you can structure the loan amount, deposit, and offset account to match your actual financial position rather than the maximum a lender will approve.

Confusing Stamp Duty Concessions With Purchase Price Limits

In New South Wales, first home buyers receive a full transfer duty exemption on properties up to $800,000 and a sliding concession on properties between $800,000 and $1,000,000. These thresholds apply to the purchase price, not the loan amount. A buyer purchasing at $850,000 with a 10% deposit will pay some duty even though they are borrowing less than $800,000. The concession phases out as the property value increases, and buyers often assume the exemption applies to the loan rather than the property.

A common scenario involves a buyer who finds a property listed at $795,000 and negotiates up to $810,000, assuming the difference is minor. The buyer moves from full exemption to partial concession, adding several thousand dollars to their settlement costs. The same buyer could have kept the purchase price at $800,000 and negotiated on settlement terms or inclusions instead.

The distinction matters because duty concessions in New South Wales are calculated on a sliding scale. A property purchased at $900,000 will attract partial duty, while a property at $1,000,001 will be subject to standard rates with no concession at all.

Using a 5% Deposit Without Understanding How Lenders Mortgage Insurance Is Waived

The Australian Government 5% Deposit Scheme allows eligible buyers to purchase with a 5% deposit without paying Lenders Mortgage Insurance. The scheme is available through 31 participating lenders, but not all lenders offer the same loan features or interest rate pricing. A buyer who applies through a lender that participates in the scheme but does not offer offset accounts or flexible repayment options may save on LMI but lose access to features that reduce interest costs over time.

Applications for the scheme are made through the lender, not through Housing Australia. The property price cap in Sydney is $1,500,000. A buyer who assumes they can apply directly to Housing Australia or who does not check whether their preferred lender participates in the scheme will delay their application or miss the opportunity entirely.

The scheme does not have income caps or annual place limits, but it does require the buyer to meet first home buyer eligibility criteria. A buyer who has previously held an ownership interest in property, even as a guarantor or through an investment, may not qualify.

Assuming All Low Deposit Options Are the Same

A 5% deposit under the government scheme, a 10% deposit with LMI, and a 5% deposit with a family guarantee are three different structures with different cost profiles. The government scheme waives LMI, which can save tens of thousands of dollars, but limits you to participating lenders and requires the property to be owner-occupied. A 10% deposit with LMI paid gives you access to a wider lender panel and may allow you to negotiate a better interest rate discount, but you pay LMI upfront or capitalise it into the loan. A family guarantee allows a 5% deposit without LMI by using a parent's property as additional security, but it places obligations on the guarantor and requires careful structuring to protect both parties.

In a scenario where a buyer has access to a 10% deposit and is comparing options, the choice between paying LMI and using the government scheme depends on the interest rate differential and the loan features available. If the LMI cost is $15,000 but the lender offers a rate 0.20% lower and includes an offset account, the buyer may recover the LMI cost within a few years through interest savings. If the government scheme lender offers the same rate and features, the scheme is the better option. The decision requires a comparison of total cost over the expected loan term, not just the upfront saving.

Overlooking the First Home Owner Grant Eligibility When Buying Established Property

The First Home Owner Grant in New South Wales is $10,000 and applies only to new builds or substantially renovated homes valued up to $600,000, or land and build contracts up to $750,000. The grant does not apply to established homes. A buyer purchasing an established apartment in Sydney will not receive the grant regardless of the purchase price. A buyer purchasing a new apartment in a development that has not yet been completed may be eligible if the contract is signed before completion and the property meets the scheme requirements.

The distinction between new and established also affects stamp duty concessions in some states, but in New South Wales the duty exemption applies to both new and established homes provided the property is used as the buyer's principal place of residence. A buyer who assumes the grant and the duty exemption have the same eligibility criteria will budget incorrectly and may need to find an additional $10,000 at settlement.

Signing a Contract Without Confirming Settlement Costs and Adjustments

Settlement costs include conveyancing fees, title search fees, mortgage registration, building and pest inspections, and any adjustments for council rates, water rates, or strata levies paid in advance by the vendor. A buyer who budgets only for the deposit and duty will be short at settlement. Conveyancing fees in Sydney typically range from $1,200 to $2,500 depending on the complexity of the transaction. Building and pest inspections add another $500 to $800. Adjustments for rates and strata levies depend on the settlement date and can add several thousand dollars if the vendor has prepaid a full quarter.

A buyer who signs a contract with a 30-day settlement period and has not accounted for these costs will need to find the shortfall quickly or risk delaying settlement. Delayed settlement can trigger penalty interest or, in some cases, allow the vendor to terminate the contract and retain the deposit.

Choosing a Fixed Interest Rate Without Understanding Break Costs

A fixed interest rate provides certainty over repayments for a set period, typically one to five years. If you need to sell the property, refinance, or make a large lump sum repayment during the fixed period, you may be charged break costs. Break costs are calculated based on the difference between the fixed rate you are paying and the lender's current cost of funds. If rates have fallen since you fixed, the break cost can be substantial. If rates have risen, the break cost may be zero or minimal.

A buyer who fixes their rate at 5.5% for three years and then needs to sell 18 months later when the lender's equivalent fixed rate has dropped to 4.8% will be charged a break cost to compensate the lender for the lost interest. The cost can run into thousands of dollars depending on the loan balance and the rate difference. A buyer who assumes they can exit a fixed rate at any time without penalty will face an unexpected cost that reduces the net proceeds from the sale.

If you are likely to sell, refinance, or make large additional repayments within the next few years, a variable interest rate or a split structure with part fixed and part variable may provide more flexibility.

Not Using the First Home Super Saver Scheme When Eligible

The First Home Super Saver Scheme allows eligible buyers to make voluntary contributions into their superannuation fund and withdraw up to $50,000 to use toward a home deposit. Concessional contributions are taxed at 15% rather than at marginal income tax rates, which for many buyers represents a saving of 20% or more. A buyer on a marginal tax rate of 37% who contributes $15,000 in a financial year will pay $2,250 in tax within super rather than $5,550 through their income tax. The saving is $3,300 in one year.

The scheme requires buyers to obtain a determination from the Australian Taxation Office before signing a purchase contract. A buyer who contributes to super with the intention of using the scheme but does not obtain the determination in time will not be able to access the funds for the deposit. The ATO determination process can take several weeks, and buyers need to plan ahead. A buyer who discovers the scheme after signing a contract and needs the funds within a fortnight will not be able to use it.

Underestimating How Long It Takes to Save a Genuine Deposit

Lenders require the deposit to come from genuine savings, which generally means funds that have been held in your account for at least three months. A buyer who receives a cash gift from a parent and deposits it two weeks before applying for a home loan may need to provide a statutory declaration confirming the gift and demonstrating that it does not need to be repaid. Some lenders will accept gifted deposits with documentation, but others apply stricter savings requirements, particularly for buyers with a deposit below 10%.

A buyer who plans to use the First Home Super Saver Scheme and a cash gift together needs to ensure both sources are documented and accepted by the lender before making an offer. A buyer who assumes the lender will accept any deposit source without question will face delays or declined applications.
