Common Mistakes First Homebuyers Make

From underestimating your budget to skipping property inspections, small mistakes can become expensive when buying a new home.

The good news is that most first home buyer mistakes are avoidable. You simply need to know what can go wrong before you sign a contract.

1. Saving For The Deposit Without Planning For Buying Costs

Saving a home loan deposit is only part of the challenge.

Many first home buyers focus on reaching a specific deposit target.

However, you also need money for other costs of buying a home.

These costs can include:

  • Transfer duty or stamp duty.
  • Conveyancing or solicitor fees.
  • Property searches.
  • Building and pest inspections.
  • Loan fees.
  • Registration fees.
  • Lenders Mortgage Insurance.
  • Home insurance.
  • Moving costs.
  • Utility connections.
  • Repairs and maintenance.

ASIC’s Moneysmart recommends allowing for buying costs alongside your deposit.  Your state or territory determines many property taxes and concessions.

Therefore, check the rules that apply where you plan to buy.

Why Your Deposit Target Can Be Misleading

Suppose you save $50,000 for a property.

That does not necessarily mean you have $50,000 available as your deposit.

You may need part of those savings for purchasing costs.

Your actual cash requirement depends on your property price, loan and eligibility.

Some government programs can also reduce the deposit you need.

For example, eligible buyers may access the Australian Government 5% Deposit Scheme. 

However, a smaller deposit does not eliminate the need for careful budgeting.

2. Believing You Need A 20% Deposit

A common first home buyer mistake is assuming you cannot buy without a 20% deposit.

A 20% deposit can reduce your loan-to-value ratio and may help you avoid LMI.

However, it is not the only pathway into home ownership.

Some lenders accept smaller deposits.

Government programs may also support eligible buyers with smaller deposits.

The Australian Government 5% Deposit Scheme can also support eligible first home buyers. 

Therefore, do not automatically delay buying simply because you have not saved 20%.

Instead, understand the total costs before deciding what deposit makes sense.

3. Confusing Your Deposit With Your Borrowing Capacity

Your deposit tells you how much money you have saved.

Your borrowing capacity tells you how much a lender may allow you to borrow.

They are two different things.

For example, you could have a large deposit but limited borrowing capacity.

You could also have strong borrowing capacity but insufficient savings.

Lenders consider your income, expenses, debts, credit history and other financial commitments. 

Therefore, calculate both numbers before seriously shopping for property.

4. Assuming The Bank Will Lend You The Maximum Amount

Getting approved for a large loan does not mean you should borrow the maximum.

This is one of the most important home buying mistakes to avoid.

Your lender assesses whether you can service the proposed loan.

However, you also need enough money left for everyday life.

Think about:

  • Groceries.
  • Transport.
  • Childcare.
  • Insurance.
  • School costs.
  • Holidays.
  • Medical expenses.
  • Repairs.
  • Unexpected bills.
  • Future lifestyle changes.

Interest Rates Can Change

Your current repayment is not necessarily your future repayment.

APRA requires banks to maintain a minimum mortgage serviceability buffer of three percentage points. 

This helps lenders assess whether borrowers could continue servicing loans under higher rates.

You should still run your own household budget.

Ask yourself whether your finances could handle higher repayments.

A loan that works today may feel very different after a major life change.

5. Relying On Online Borrowing Calculators Alone

Online calculators can help you understand your potential borrowing range.

However, they cannot capture every detail of your financial situation.

Different lenders can assess income, expenses and existing commitments differently.

Therefore, treat calculator results as estimates rather than guarantees.

6. Making New Credit Applications Before Buying

Applying for new credit can create problems before your home loan application.

You might want a new car loan.

Perhaps you also want a new credit card.

You may even decide to finance furniture for your future home.

However, new debts can affect your home loan borrowing capacity.

Lenders assess your existing financial commitments when considering your application. 

Therefore, avoid taking on unnecessary debt while preparing to buy.

Also, check your credit report before applying.

Correcting errors early can prevent unnecessary complications later.

7. Treating Pre-Approval Like Final Approval

A home loan pre-approval can help you understand your buying range.

However, pre-approval does not mean your loan is guaranteed.

You still need to find a suitable property.

The lender may then assess the property before providing final approval.

Your circumstances can also change between pre-approval and final approval.

Therefore, avoid making financial decisions based solely on a pre-approval amount.

8. Forgetting That The Property Also Matters

Your finances are only one part of the lending assessment.

The property itself can also affect the lender’s decision.

A lender may order a property valuation before finalising your loan.

The valuation may differ from the purchase price.

Housing Australia specifically notes that property value can differ from the purchase price under the First Home Guarantee. 

This creates a potential problem if you pay more than the lender’s accepted value.

You may need additional savings to cover the difference.

How To Reduce This Risk

Before making an offer, research recent comparable sales.

Look at similar properties in the same area.

Consider the property’s condition, size, location and features.

Most importantly, avoid assuming every property will increase in value.

9. Falling In Love With The Property Before Checking The Numbers

The emotional side of buying your first home can be powerful.

You walk through a property and immediately picture your future there.

Then the numbers start looking less important.

This can lead to overpaying for a property.

Before making an offer, establish your maximum price.

Then compare that price against recent comparable sales.

The First Home You Buy Does Not Need To Be Perfect

Your first property does not have to be your forever home.

Your circumstances may change over time.

You could change jobs, start a family or move closer to work.

Therefore, focus on what you need now and what may matter later.

Think about:

  • Location.
  • Transport.
  • Property size.
  • Storage.
  • Future renovations.
  • Local amenities.
  • Resale appeal.
  • Potential rental demand.

A practical first home can provide a useful stepping stone.

10. Searching Only In Your Ideal Suburb

Many first home buyers become attached to one suburb.

Then they discover that suitable properties exceed their budget.

Instead, expand your search carefully.

Look at nearby suburbs with similar amenities.

Compare:

  • Property prices.
  • Public transport.
  • Schools.
  • Shops.
  • Employment access.
  • Parks.
  • Future infrastructure.
  • Flood risk.
  • Development activity.

Moving one suburb further away can sometimes change your options significantly.

However, do not sacrifice essential needs simply to secure a cheaper property.

11. Ignoring Your Future Lifestyle

Your first home needs to work beyond moving day.

Think about how your life could change over the next several years.

You might:

  • Start a family.
  • Adopt a pet.
  • Work from home.
  • Change jobs.
  • Start a business.
  • Need additional storage.
  • Support an ageing family member.

A property that works perfectly today may become restrictive later.

Therefore, consider your likely needs before choosing a property.

12. Forgetting About Ongoing Home Ownership Costs

The purchase price is only one part of the cost of owning a home.

You also need to budget for ongoing expenses.

These can include:

  • Mortgage repayments.
  • Council rates.
  • Home insurance.
  • Utilities.
  • Repairs.
  • Maintenance.
  • Body corporate fees.
  • Strata costs.
  • Land tax where applicable.

Build A Cash Buffer

Your home can eventually need expensive repairs.

A broken hot-water system can appear at the worst possible time.

So can plumbing problems, electrical faults or roof repairs.

Keeping an emergency fund can give you more financial breathing room.

Do not use every dollar of your savings to complete the purchase.

13. Forgetting About Lenders Mortgage Insurance

A smaller deposit can help you enter the property market sooner.

However, borrowing above certain LVR levels can involve Lenders Mortgage Insurance.

LMI protects the lender rather than you.

LMI may apply when you borrow more than 80% of the property’s 

Therefore, include LMI when calculating your total purchase costs.

Do not assume your entire deposit can go towards the property price.

14. Missing Government Assistance You May Qualify For

Another common mistake is failing to check available assistance.

Government programs can change over time.

They can also have specific eligibility requirements.

For example, eligible buyers may access the Australian Government 5% Deposit Scheme. (

The First Home Super Saver Scheme can also help eligible buyers save through voluntary super contributions. 

The scheme allows eligible contributions of up to $15,000 per financial year.

The total eligible contributions are capped at $50,000.

State and territory programs can provide additional concessions or grants.

However, eligibility varies between jurisdictions.

Therefore, check the current official rules before relying on any scheme.

First Home Buyer Grants Can Have Strict Conditions

For example, Queensland’s First Home Owner Grant currently provides $30,000 for eligible new homes.

The grant applies to new homes valued below $750,000.

Established homes do not qualify for this particular grant.

Other states have different rules.

Always check the relevant state revenue office before including a grant in your budget.

15. Skipping Building And Pest Inspections

A beautiful home can hide expensive problems.

Fresh paint can cover damage.

New flooring can conceal issues underneath.

A tidy garden tells you very little about termites or drainage.

That is why a building and pest inspection can be valuable.

The inspection may identify problems before you become legally committed to the purchase.

The cost of an inspection can be small compared with major repair bills.

Do Not Rely On The Seller’s Inspection Alone

Where possible, use an appropriately qualified and independent inspector.

You want the inspection to identify problems rather than simply reassure you.

Depending on the property, you may also investigate:

  • Structural issues.
  • Termites.
  • Water damage.
  • Roof problems.
  • Drainage.
  • Electrical issues.
  • Plumbing.
  • Asbestos.
  • Renovation work.
  • Flood risk.

16. Ignoring Flood And Planning Risks

The house itself is not the entire property.

You also need to understand the surrounding area.

Check whether the property sits in a flood-prone area.

Look at zoning and planning information.

Investigate nearby development proposals.

Consider future roads, transport projects and large developments.

These factors can affect how you use the property.

They can also affect future buyers’ interest.

This is particularly important in areas where flooding or rapid development creates additional property risks.

17. Cutting Corners To Save Money

Buying your first home already involves significant expenses.

That can make you want to cut costs wherever possible.

However, some expenses exist to protect you.

A professional inspection is one example.

Legal advice is another.

Conveyancing can identify contractual issues before they become expensive problems.

Trying to save a small amount upfront can sometimes create a much larger cost later.

18. Not Reading The Contract Of Sale

The contract of sale contains important details about the purchase.

It can set out:

  • Purchase price.
  • Deposit requirements.
  • Settlement date.
  • Conditions.
  • Special terms.
  • Inclusions.
  • Exclusions.
  • Finance arrangements.

Never assume every property contract works the same way.

Property laws also vary between Australian states and territories.

Get appropriate legal or conveyancing advice before signing.

19. Treating Auctions Like Private Sales

An auction can create intense pressure.

Bidding happens quickly.

Other buyers may keep raising their offers.

That pressure can cause you to exceed your intended budget.

However, the bigger issue is the contract. Auction purchases generally have no cooling-off period. 

The sale is also generally not conditional on finance or a building and pest inspection.

Therefore, complete your due diligence before bidding.

Before An Auction

Make sure you understand:

  • Your maximum bid.
  • Your available deposit.
  • Your finance position.
  • The property’s value.
  • Building and pest findings.
  • The contract terms.
  • The settlement requirements.

Then stick to your maximum bid.

Do not let another bidder determine your budget.

20. Making An Offer Without Understanding Property Values

The asking price is not automatically the property’s market value.

Sellers choose asking prices for different reasons.

Agents may also use different pricing strategies.

Therefore, research comparable properties.

Look for recent sales involving similar:

  • Property types.
  • Land sizes.
  • Locations.
  • Bedrooms.
  • Bathrooms.
  • Parking.
  • Property conditions.

This gives you better context before negotiating.

21. Ignoring The Bank Valuation

A lender may value the property before finalising your loan.

Suppose you agree to pay $700,000.

The lender may value the property at $670,000.

Your financing position could then change.

You may need additional funds to complete the purchase.

This is particularly important when you have a small deposit.

Therefore, avoid assuming the lender will automatically finance the agreed purchase price.

22. Assuming Property Prices Will Always Rise

Property markets move through different conditions.

Prices can rise, fall or remain relatively flat.

Therefore, avoid buying a property solely because you expect rapid growth.

Your first home should still make sense if growth takes longer than expected.

Focus on affordability and suitability first.

Future price growth should not be the only reason you can justify the purchase.

23. Trying To Time The Property Market Perfectly

a clock trying to time the property market

Waiting for the perfect market can keep you waiting indefinitely.

Nobody knows exactly when prices will reach their lowest point.

You also cannot know precisely when the next growth period will begin.

Instead, focus on factors you can control.

These include:

  • Your deposit.
  • Your income.
  • Your debts.
  • Your budget.
  • Your property research.
  • Your loan structure.
  • Your emergency savings.

The goal is not to predict every market movement.

The goal is to make a purchase you can afford and manage.

24. Getting Desperate After Missing Out

Missing out on several properties can become exhausting.

You may eventually start thinking that any home is better than no home.

That is when emotions can take over.

You might overlook defects.

You could increase your offer too far.

You may even compromise on essential requirements.

Take a step back when frustration starts affecting your decisions.

There will always be another property.

Your first home is too significant a purchase for desperation to control the process.

25. Shopping For A Home Before Getting Your Finances Ready

It is tempting to start attending inspections immediately.

However, looking at properties before understanding your budget can create unrealistic expectations.

You may fall in love with homes outside your affordable range.

Then cheaper properties can feel disappointing.

Instead, work out your likely borrowing capacity first.

Then set a realistic price range.

26. Comparing Home Loans Based Only On The Interest Rate

The lowest advertised rate does not automatically mean the cheapest loan for you.

You should also consider:

  • Fees.
  • Comparison rate.
  • Loan features.
  • Offset accounts.
  • Redraw conditions.
  • Extra repayment rules.
  • Fixed-rate conditions.
  • Break costs.
  • Loan flexibility.

We recommend comparing costs, features and conditions rather than looking at one figure.

A slightly different rate can make a substantial difference over a long loan term.

However, the cheapest loan depends on your circumstances and how you use the loan.

27. Forgetting To Review Your Loan Before Settlement

Home insurance text

Finding a property does not mean your work is finished.

Your lender still needs to complete the final approval process.

Your conveyancer or solicitor also needs to prepare for settlement.

You should keep your finances stable during this period.

Avoid unnecessary new debts.

Avoid large unexplained transactions.

Keep your employment and income information up to date.

A smooth settlement depends on more than simply signing the contract.

28. Forgetting Home Insurance

Your new home represents one of your largest financial commitments.

Protecting it should therefore be part of your buying plan.

The timing and insurance requirements can vary depending on your state and contract.

Therefore, understand when your insurance responsibility begins.

Do not leave this until the last minute.

29. Assuming Your First Home Must Be Your Forever Home

Your first home can be a stepping stone.

You may later upgrade.

You may move for work.

You may change your family structure.

You may decide you prefer a different location.

Therefore, you do not necessarily need to buy your dream home immediately.

Instead, look for a property that works financially and practically.

A sensible first home can help you establish yourself in the property market.

30. Rushing The Decision Because Someone Else Is Buying

Property searches can become competitive.

You may hear that another buyer is interested.

You may be told that an offer needs to happen immediately.

Sometimes urgency is genuine.

However, you still need to protect your financial position.

Do your research.

Check the property.

Understand the contract.

Confirm your finance position.

Then decide whether the property works for you.
