The True Cost of Buying Your First Home (Beyond the Purchase Price)

Most first home buyers fixate on one number, the purchase price. Fair enough. It is the giant six or seven digit monster sitting in every realestate.com.au listing.

But the price on the ad is not the full cash you need to get through the deal. In Australia, buying your first home usually means budgeting for deposit + buying costs + move-in costs + a safety buffer. Miss the extra bits and you can end up technically approved by the bank, but still uncomfortably broke by settlement. Not ideal. Very character building, but not ideal.

If you want a quick reality check, start with the Borrowing Capacity Calculator, then run the Stamp Duty Calculator and the LMI Calculator. Those three usually expose the gap between “we have a deposit” and “we are genuinely ready to buy”.

The simple formula

For most first home buyers, the real upfront number looks something like this:

Total cash needed = deposit + stamp duty or transfer duty + legal fees + inspections + lender costs + insurance + moving setup costs + emergency buffer.

The exact figure changes by state, property price, loan size and whether you qualify for a first home buyer concession. That is why using a generic rule like “just save 10 percent” is how people accidentally walk into a spreadsheet ambush.

1. The deposit is only the starting point

Your deposit is the chunk of the purchase price you contribute yourself. In plain English:

• 20 percent deposit: usually avoids LMI
• 10 percent deposit: common, but LMI may apply
• 5 percent deposit: possible for some buyers, especially with schemes, but cash flow gets tighter and the margin for error shrinks fast

A smaller deposit can get you in sooner, but it often means a larger loan, higher repayments, and either LMI or tighter lender rules. If you are not sure what your repayments look like after the deposit choice, check the Mortgage Calculator as well. This is where optimism goes to be politely corrected.

2. Stamp duty can be tiny, reduced, or absolutely rude

Stamp duty, sometimes called transfer duty, is one of the biggest extra costs buyers forget. The tricky bit is that it varies by state and territory, and first home buyer concessions also vary by location and property value.

That means two buyers with the same income and the same deposit can face wildly different cash requirements depending on where they buy. In some cases the concession wipes the duty bill out. In others it only softens the blow. In others it is still a proper financial jump scare.

Do not estimate this from memory or from a mate who bought in another state two years ago. Use the Stamp Duty Calculator for the actual property price and state you care about.

3. LMI is not a fine, but it is still expensive

If you borrow more than 80 percent of the property value, many lenders will charge Lenders Mortgage Insurance, or LMI. Despite the name, it protects the lender, not you. Yes, Australian finance has a few jokes built into the system.

LMI can sometimes be added to the loan instead of paid upfront, but that does not make it free. It just means you borrow more and pay interest on a bigger balance. That can still be the right move if buying earlier saves you years of waiting, but you want to know the trade-off before signing anything.

If your deposit is below 20 percent, run the LMI Calculator. Then compare that with the cost of waiting longer to save. Sometimes paying LMI makes sense. Sometimes it is just the price of impatience in a nice shirt.

4. Conveyancing and legal fees are boring, necessary, and real

You will usually need a conveyancer or solicitor to handle the legal side of the transaction. Their job is to review the contract, manage key checks, coordinate settlement, and stop obvious paperwork disasters from becoming your personality.

Fees vary by provider and complexity, but this is not a cost to ignore. Cheap can be fine. Suspiciously cheap can become expensive later. Ask what is included, whether searches are extra, and what happens if the deal falls over before settlement.

5. Building and pest inspections are optional until they really are not

For houses, a building inspection and often a pest inspection can save you from buying someone else’s structural surprise. For apartments, the relevant checks may be different, but you still want to understand strata records, defects, and ongoing issues.

Skipping inspections to save a few hundred dollars can feel clever right up until you discover drainage issues, termites, illegal renovations, or a roof that appears to be held together by hope and old silicone.

6. Lender fees and settlement costs still show up

Even if your interest rate looks good, there can still be bank application fees, settlement fees, valuation fees, or package fees depending on the lender and loan structure. Not every lender charges the same way, and sometimes a cheaper advertised rate comes bundled with annual fees or fewer useful features.

This is also why first home buyers should compare the whole setup, not just the headline rate. A lower rate is great. A lower rate plus annoying fees, limited offset access and poor turnaround time, less great.

7. Insurance starts before the boxes arrive

For many purchases, you should have building insurance arranged from settlement, and sometimes earlier depending on the contract and state rules. If you are buying a freestanding house, that matters. If you are buying a strata property, some cover may already exist through the owners corporation, but you still need to understand what is and is not covered.

Then there is contents insurance, which people love to ignore until they remember TVs, laptops and furniture cost actual money.

8. Moving costs are not glamorous, but they count

Removalists, truck hire, cleaning, utility connections, redirecting mail, internet setup, basic tools, curtains, blinds, extra furniture, replacement appliances, and changing locks. None of these are exciting individually. Together they can easily take a meaningful bite out of your cash buffer.

First home buyers often treat move-in spending like it is optional lifestyle fluff. Some of it is. Some of it is “the house has no fridge, no blinds, and one mystery key held by three previous tenants”. Budget accordingly.

9. Adjustments and surprise line items happen at settlement

At settlement, there may be adjustments for council rates, water rates, or strata levies depending on the property and timing. These are normal transaction mechanics, but they still affect how much cash you need on the day.

This is one reason buyers should avoid running their bank account down to the last dollar. Property transactions are not famous for saying, “No worries, pay us next Thursday.”

10. Keep a post-settlement buffer or future-you will be cranky

This is the part too many people skip. Even if the bank approves the loan, that does not mean it is wise to empty every account to get there. A buffer helps with rate rises, urgent repairs, appliance failures, and the general chaos of the first few months.

If you buy a place and have exactly $38 left afterwards, you have not “maximised your opportunity”. You have created a personal finance escape room.

A quick worked example

Imagine you are buying a $700,000 home with a 10 percent deposit.

• Deposit: $70,000
• Stamp duty: could be reduced, exempt, or still substantial depending on state and eligibility
• LMI: may apply because you are borrowing above 80 percent LVR
• Legal and inspection costs: more cash needed before settlement
• Insurance, moving and setup: more cash again
• Buffer: ideally still something left after the dust settles

So no, this buyer does not just need $70,000. They need $70,000 plus whatever all the surrounding costs add up to in their state and loan setup. This is why buyers who seem “so close” sometimes realise they are still several thousand dollars short once the full list is on the table.

What to do next

1. Check your borrowing capacity
2. Calculate duty for your state with the Stamp Duty Calculator
3. Test your deposit scenario with the LMI Calculator
4. Estimate repayments with the Mortgage Calculator
5. Add legal fees, inspections, moving costs and a real cash buffer before calling yourself ready

Final word

The purchase price gets all the attention, but the true cost of buying your first home is everything wrapped around it, the duty, insurance, legal work, inspections, bank fees, moving costs and the money you still need left over when the excitement wears off.

Do the ugly maths early. It is a lot less painful than discovering the truth halfway through the process with a signed contract and a rapidly deteriorating mood.

FAQ

How much money do first home buyers need on top of the deposit?

It depends on the property price, location and loan setup, but many buyers need several thousand dollars to tens of thousands on top of the deposit once duty, legal fees, inspections, insurance and moving costs are included.

Do first home buyers always pay stamp duty?

No. Concessions and exemptions vary by state and price thresholds, so some buyers pay reduced duty or none at all, while others still face a meaningful bill.

Can LMI be added to the loan?

Often yes, depending on the lender and LVR, but that increases the amount you borrow and can mean more interest over time.

What do buyers forget most often?

Inspections, conveyancing, insurance, utility setup, immediate repairs and a post-settlement emergency buffer are the repeat offenders.
