When to Avoid Common First Home Buyer Mistakes

Understanding the most common missteps first home buyers make in Canberra and Griffith, and how to avoid them before you apply.

The most expensive mistakes first home buyers make happen before they ever submit an application.

Many buyers in Canberra and Griffith move forward without understanding their borrowing capacity, miss eligibility windows for schemes like the First Home Guarantee, or lock themselves into loans without considering how their needs might change. These errors can cost tens of thousands of dollars or delay a purchase by months.

Applying Before You Know What You Can Borrow

Your borrowing capacity is not the same as the amount a lender will approve once they assess your application. Borrowing capacity is an estimate based on your income, debts, and living expenses. The actual amount you can borrow depends on verification of those details and the lender's credit policy at the time.

Consider a buyer who earns $85,000 per year and has a $12,000 personal loan and a $6,000 credit card limit. Their rough borrowing capacity might be around $450,000 to $480,000, but that figure shifts if the lender applies a higher expense benchmark or includes the full credit card limit as a potential debt. If that buyer is looking at properties in Griffith, where the median unit price has been sitting in the mid $500,000 range, they would need a deposit well above the minimum to bridge the gap between what they want to spend and what they can borrow.

Understanding borrowing capacity before you attend open homes keeps your search realistic and prevents disappointment once you apply.

Missing Out on Stamp Duty Concessions and Grants

The ACT does not offer cash grants for first home buyers, but stamp duty concessions are available and can reduce upfront costs significantly. Many buyers assume they are not eligible because they earn too much or are buying an established home, but the ACT concession structure is different from other states.

Unlike Queensland or Victoria, where grants are tied to new builds, the ACT stamp duty concession applies to both new and established properties, subject to value thresholds that are updated regularly by the ACT Revenue Office. If you are buying in suburbs like Griffith, where established homes dominate the market, this concession can be the difference between needing an extra $15,000 in cash or not.

Federal schemes like the First Home Guarantee are also available without income caps as of late 2025, allowing eligible buyers to purchase with a 5% deposit and no Lenders Mortgage Insurance. Failing to check eligibility before you start searching can mean missing a scheme that would have brought your purchase forward by a year or more.

Choosing a Loan Based Only on the Interest Rate

The lowest advertised interest rate is not always the lowest cost loan over the life of your mortgage. Rate is one factor, but fees, features, and flexibility matter just as much.

A lender offering a variable interest rate 0.15% lower than a competitor might also charge a $395 annual fee, restrict access to an offset account unless you hold other products with the bank, and apply higher break costs if you refinance within three years. Over a five-year period, that advertised saving disappears.

In Canberra, where many buyers work in the public service and have predictable income, an offset account is often more valuable than a marginal rate discount. Salary gets deposited fortnightly into the offset, reducing the interest charged on the loan without requiring extra repayments. A buyer with $20,000 sitting in an offset account linked to a $500,000 loan at 6.2% saves around $1,240 per year in interest. If the loan without the offset was 0.1% cheaper, the annual saving would be around $500. The offset wins.

When comparing home loan options, look at the total cost over the period you expect to hold the loan, not just the rate in the first year.

Skipping Pre-Approval or Treating It as a Formality

Pre-approval is not a guarantee, but it is also not a rubber stamp. It involves a lender assessing your income, debts, expenses, and credit file, then giving conditional approval subject to property valuation and final checks.

Some buyers treat pre-approval as a formality and submit minimal documentation, then find out at settlement that the lender requires additional payslips, explanations for irregular deposits, or proof that a gift deposit came from a family member and not a loan. These requests are not new requirements. They were always part of the assessment, but the buyer did not provide enough detail upfront.

A solid pre-approval for a first home loan application involves submitting at least three months of payslips, bank statements showing genuine savings, and any relevant documentation for schemes like the First Home Guarantee. If your deposit includes a gift, have a signed declaration from the person providing it. If you have changed jobs recently, provide an employment contract. These steps do not speed up the process, but they do reduce the chance of delays once you go unconditional.

Locking Into a Fixed Interest Rate Without Understanding Your Situation

Fixed interest rates provide certainty, but they also remove flexibility. You cannot make extra repayments beyond a set limit, usually $10,000 to $30,000 per year, and you cannot access an offset account with most fixed rate products.

If your income is likely to increase, or you expect a bonus or inheritance in the next few years, a fixed rate loan might cost you more in lost offset savings or restricted repayments than it saves in rate protection. A buyer in Griffith who fixes at 5.8% for three years and then receives a $40,000 redundancy payout cannot put that money into an offset to reduce interest. They either pay it off the loan and trigger early repayment fees, or leave it in a savings account earning 4.5% while paying 5.8% on the mortgage.

Splitting the loan between fixed and variable portions is common, but only if it matches your circumstances. Fixing for the sake of certainty when you have irregular income or expect lump sums is a mismatch.

Underestimating Upfront Costs Beyond the Deposit

The deposit is the largest upfront cost, but it is not the only one. Settlement costs including conveyancing, building and pest inspections, and loan establishment fees add up quickly.

A buyer using the First Home Guarantee with a 5% deposit on a property in Canberra will avoid Lenders Mortgage Insurance, but still needs to budget for conveyancing costs of around $1,500 to $2,500, inspections of $500 to $800, and potential lender fees of $600. If they have exactly 5% saved and nothing else, they cannot settle.

The First Home Super Saver Scheme allows you to withdraw up to $50,000 from superannuation for a deposit, but many buyers do not realise this can also cover some settlement costs if structured correctly. Contributions are taxed at 15% going in, and you pay your marginal tax rate minus a 30% offset when you withdraw, so for most first home buyers the effective tax rate is lower than saving in a standard bank account.

Understanding the full cost structure before you make an offer prevents last-minute scrambling for funds or having to delay settlement.

Ignoring Loan Features That Match How You Actually Live

Redraw facilities and offset accounts both reduce the interest you pay, but they work differently. A redraw facility lets you access extra repayments you have made, but the lender controls access and can restrict it. An offset account is a transaction account linked to your loan. The balance in the offset reduces the amount of interest charged, and you control the funds.

If you are disciplined and make extra repayments without needing access, redraw works. If you want flexibility to access funds without asking permission, offset is the better option. Many first home buyers choose based on what the lender offers rather than what suits their financial habits.

A buyer in Canberra who uses their offset account as their primary transaction account and maintains a balance of $15,000 saves around $930 per year in interest on a $450,000 loan at 6.2%. If that same buyer had a redraw facility but did not make extra repayments because they wanted to keep funds accessible, they save nothing.

Choosing loan features based on how you manage money day-to-day, rather than what sounds useful in theory, makes a measurable difference over time.

Frequently Asked Questions

What is the difference between borrowing capacity and loan approval?

Borrowing capacity is an estimate based on your income, debts, and expenses. Loan approval is the actual amount a lender will lend after verifying your details and assessing the property. Your capacity is a guide, not a guarantee.

Can I use the First Home Guarantee in the ACT?

Yes, the First Home Guarantee is a federal scheme available in the ACT. It allows eligible buyers to purchase with a 5% deposit and no Lenders Mortgage Insurance, and has no income caps as of late 2025.

Should I fix my interest rate as a first home buyer?

Fixing your interest rate depends on your income stability and whether you expect lump sum payments. Fixed rates remove flexibility for extra repayments and offset accounts, so they suit buyers with steady income who value certainty over access to funds.

What upfront costs do I need besides the deposit?

You need to budget for conveyancing fees, building and pest inspections, and loan establishment fees. These can total $2,500 to $4,000 depending on the property and lender, and must be paid at or before settlement.

Is an offset account or redraw facility better for a first home buyer?

An offset account gives you full control over your funds and reduces interest daily based on the balance. A redraw facility lets you access extra repayments but is controlled by the lender. Offset suits buyers who want flexibility, redraw suits those who make extra repayments and rarely need access.
