First Home Buyer Mistakes to Avoid in Australia (2026)
Buying your first home is an exciting milestone, but it comes with significant financial complexity. Many first home buyers make costly mistakes that take years to recover from — often because they didn’t know what they didn’t know.
This guide covers the most common and expensive first home buyer mistakes in Australia.
Mistake 1 — Not Getting Pre-Approval Before Searching
Many first home buyers spend months searching for properties before understanding their borrowing capacity. This leads to:
- Falling in love with a property outside your budget
- Being outcompeted at auction by buyers who have finance ready
- Disappointment when a lender approves less than expected
What to do instead: Get formal pre-approval before starting your search. Pre-approval typically takes 2–5 business days and is valid for 3–6 months. It locks in your price range and gives confidence when making offers.
Mistake 2 — Not Checking All the Costs Beyond the Deposit
First home buyers often focus only on the deposit, underestimating the full upfront cost. Stamp duty, conveyancing, inspections, LMI and moving costs can add $5,000–$50,000 to the purchase cost.
Total upfront cost checklist:
- Deposit (5–20% of purchase price)
- Stamp duty (may be zero with FHB concession — check your state)
- Conveyancing/legal fees ($1,500–$3,500)
- Building and pest inspection ($400–$900)
- LMI if deposit is below 20% and not using the First Home Guarantee
- Lender fees (check for establishment/valuation fees)
- Moving costs ($800–$2,500)
- Initial home setup costs (furniture, appliances — often overlooked)
See the true cost of homeownership guide for a complete breakdown.
Mistake 3 — Borrowing the Maximum You Can Get
Many first home buyers treat their pre-approval limit as a target, not a ceiling. Borrowing at maximum capacity leaves no buffer for:
- Interest rate rises (the RBA can move 0.25–0.50% per meeting)
- Unexpected job loss or income reduction
- Property maintenance costs
- Life changes — children, medical expenses, career change
The buffer test: Can you still make repayments if rates rise by 2%? Can you survive 3 months without income? These stress tests are important before committing to a loan size.
Mistake 4 — Skipping the Building and Pest Inspection
A building and pest inspection ($400–$900) seems like an easy cut when you’re already stretched on costs. It is not. Undiscovered termite damage, structural issues or waterproofing failures can cost $30,000–$150,000 to remediate.
When inspections matter most:
- Properties built before 1980 (greater risk of asbestos, aging infrastructure)
- Properties with extensions or renovation work (permit compliance issues)
- Queensland and tropical areas (higher termite prevalence)
- Properties showing signs of settlement, damp or roof issues at inspection
For off-the-plan purchases, a defects inspection after handover is essential — builder defects are common and must be documented within the defects liability period.
Mistake 5 — Not Understanding Strata Before Buying an Apartment
Apartments come with ongoing strata (body corporate) fees and shared liability for building maintenance. First home buyers often don’t adequately research:
- Annual strata levies — can range from $3,000 to $15,000+ per year
- Sinking fund balance — a depleted sinking fund means special levies for major works are likely
- Strata report — reveals pending litigation, building defects and financial health of the scheme
- By-laws — may restrict short-term letting, pets, renovations or subletting
Always review the strata report before exchanging contracts. A strata-specialist solicitor can assist with interpreting the documents.
Mistake 6 — Ignoring Scheme Eligibility
Many first home buyers don’t realise they’re eligible for schemes that could save tens of thousands of dollars:
- First Home Guarantee — save $15,000–$40,000 in LMI premiums
- First Home Owner Grant — $10,000–$30,000 cash (QLD) for new builds
- Stamp duty exemptions — up to $31,000+ in savings (NSW, VIC)
- FHSS scheme — thousands saved in tax by using super for the deposit
Check all scheme eligibility before signing any contract.
Mistake 7 — Buying Based on Emotion, Not Fundamentals
A property that “feels like home” on inspection day can hide significant problems — or simply be overpriced. First home buyers are particularly vulnerable to emotional decision-making.
Questions to ask before any purchase:
- Is the price reasonable compared to recent comparable sales in the suburb?
- What are the local vacancy rates and rental yields? (Indicates underlying demand)
- What is driving the local economy? (Single-industry towns carry concentration risk)
- Is there infrastructure planned nearby that could affect value positively or negatively?
- What are the ongoing costs — council rates, water rates, strata?
Mistake 8 — Not Comparing Multiple Lenders
Many first home buyers accept the first loan offer they receive — often from their existing bank. The difference between lenders can be 0.25–0.75% in interest rate, which on a $600,000 loan equals $88–$263/month or $31,000–$95,000 over 30 years.
A mortgage broker can compare rates across 30–40 lenders simultaneously. This takes hours rather than weeks of direct negotiation and typically costs the buyer nothing (the broker is paid by the lender).
Mistake 9 — Not Reading the Loan Documents
Home loan contracts contain terms about:
- Discharge fees if you switch lenders early
- Restrictions on extra repayments (fixed rate loans often cap extra repayments at $10,000–$20,000/year)
- Offset account terms — not all “offset accounts” are 100% offset
- Rate review clauses and break costs for fixed rates
Before signing, read the credit contract and key facts sheet. Ask your broker or lender to explain any terms you don’t understand.
Mistake 10 — Stretching for a Property That Doesn’t Meet Your Needs
Buying the “maximum you can afford” in a location you’re not happy with — because that’s all that’s available in budget — can lead to costly mistakes: high commuting costs, lifestyle dissatisfaction, or having to sell within 2–3 years (incurring stamp duty, agent commissions and moving costs twice).
The 3-year rule: Can you see yourself in this property for at least 3–5 years? The transaction costs of buying and selling typically require 3–5 years of ownership to break even financially.
Frequently Asked Questions
What is the most common mistake first home buyers make? The most common and costly mistake is not understanding the full upfront costs — many first home buyers are surprised by stamp duty, LMI, legal fees and inspection costs on top of the deposit.
Should I use a mortgage broker or go directly to a bank? A mortgage broker compares multiple lenders simultaneously and is typically free to the buyer. For first home buyers with complex situations (HECS debt, irregular income, low deposit), a broker experienced with first home buyer schemes can add significant value.
What if I bought a property with a problem I didn’t know about? If a defect was non-disclosed by the vendor, you may have legal recourse — speak with your solicitor. If the building inspection missed it, you may have a claim against the inspector. This underlines why both contracts and inspections should always be reviewed professionally.
