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

Most first home buyers obsess over the deposit, then get blindsided by everything else. Fair enough. "Save a deposit" is the bit everyone talks about. "Also keep cash ready for duty, legal fees, inspections, insurance, lender costs and whatever weird little moving-day chaos appears" does not make the same cute Instagram reel.

The truth is the purchase price is only the headline number. The real cost of buying your first home in Australia is the deposit plus a stack of upfront expenses that can seriously change how much cash you need before settlement.

If you want the short version, use the Stamp Duty Calculator, the LMI Calculator and the Borrowing Capacity Calculator together. That trio will usually tell you more truth than one optimistic Sunday inspection.

The cost stack most buyers actually face

For an owner-occupier buying their first place, the main upfront costs usually look like this:

• deposit
• stamp duty or transfer duty, if applicable
• conveyancing or solicitor fees
• building and pest inspections
• lender fees and settlement costs
• lenders mortgage insurance, if you borrow above 80% LVR and do not qualify for a waiver or guarantee
• building insurance
• moving costs and immediate setup costs

Some buyers dodge part of that list through first home buyer concessions or government guarantee schemes. Some do not. That is exactly why broad rules like "you only need a 5% deposit" are a bit dangerous on their own. You might get in with 5%, but you still need cash for the rest of the circus.

1. The deposit is only the entry ticket

Your deposit is the chunk of the purchase price you are not borrowing. Common benchmarks are 5%, 10% and 20%.

• 20% deposit: usually avoids LMI, but takes longer to save.
• 10% deposit: easier to reach, but may still attract LMI.
• 5% deposit: possible for some buyers, especially with guarantee schemes, but the rest of the upfront costs do not magically disappear.

That is why a buyer with a smaller deposit can still need a surprisingly large cash buffer. Even when the deposit hurdle shrinks, the legal and transactional costs keep showing up like unpaid extras in a streaming bundle.

2. Stamp duty is often the biggest extra hit

For many buyers, stamp duty is the nastiest surprise after the deposit. It is a state or territory tax, the rules vary by location, and first home buyer concessions can change the number massively.

In some cases you might pay nothing. In other cases it is a five-figure cost that lands right before settlement and makes your bank account question your life choices.

There is no single Australia-wide shortcut here. The amount depends on:

• the state or territory
• the purchase price
• whether the property is new or established
• whether you qualify for a first home buyer exemption or concession

This is the first reason buyers should stop using random Reddit comments as their finance strategy. The exact stamp duty number is easy to get wrong and often too big to improvise around later.

3. Conveyancing is not optional admin fluff

You will also need a conveyancer or property solicitor to review the contract, run searches, handle title transfer paperwork and coordinate settlement. This is not the bit to get aggressively cheap on.

The exact fee depends on the state, the property, and how messy the contract is, but it is usually a low-thousands kind of cost, not a "rounding error" cost. If the property has unusual conditions, body corporate issues, or a contract that looks like it was assembled by chaos itself, expect the legal bill to lean higher.

A good conveyancer can also save you from more expensive mistakes later, which is a pretty strong return on investment for paperwork nobody enjoys.

4. Inspections are boring until they save you a fortune

Building and pest inspections are another cost people are tempted to skip, especially when the market feels competitive. Bad move. A few hundred dollars for a proper inspection is cheap compared with discovering structural damage, drainage issues or termites after you own the problem.

If you are buying at auction, you may need to pay for inspections before auction day because you usually cannot make an auction purchase conditional afterward. Annoying, yes. Still better than buying a lovely-looking money pit with fresh paint and strong photography.

5. Lender fees still matter, even when the headline rate looks good

Some home loans come with application fees, settlement fees, valuation fees, annual package fees or discharge fees later if you refinance. Plenty of lenders have reduced or scrapped some upfront charges, but not all of them.

That means two loans with similar interest rates can still feel different on day one. If cash is already tight, a few extra lender costs are not nothing.

This is also where a broker can be useful. Not because brokers are magical woodland creatures, but because they can compare lender policies and point out where the cheap-looking loan is only cheap from one angle.

6. LMI can turn a small deposit into a much bigger bill

If you borrow more than 80% of the property's value and you do not qualify for an exemption, waiver or government guarantee, you may need to pay lenders mortgage insurance.

LMI protects the lender, not you. Which is a slightly rude concept when you first hear it, but there we are.

The cost depends on the loan size and the loan-to-value ratio. On a larger purchase, it can easily run into the thousands or even well into five figures. Sometimes it is paid upfront. Often it is capitalised onto the loan, which means you borrow it and then pay interest on it too.

That is why a 10% deposit is not always "halfway to 20%" in any simple sense. The cash target and the long-term loan cost can look quite different once LMI enters the room.

If you want to test whether paying LMI now beats waiting longer to save, use the LMI Calculator. It is much better than guessing and hoping your future self will be impressed.

7. Insurance starts earlier than some buyers expect

Building insurance is another line item that catches people late. Many lenders require it before settlement, and depending on the state and the contract, the risk can pass to the buyer before settlement day. Your conveyancer should tell you exactly when cover needs to start.

The premium will depend on the property type, location and risk profile. A flood-prone or bushfire-prone area can change the number quickly, and that is before contents insurance joins the chat.

This is not just a compliance box. If you are stretching to buy, the last thing you want is a nasty insurance cost surprise after you have already committed.

8. Moving and setup costs are small individually, painful collectively

Then you get to the bit everyone forgets because it is not glamorous:

• removalists or van hire
• utility connection or transfer fees
• internet setup
• lock changes
• basic repairs
• cleaning, paint, hardware-store trips and other sneaky move-in costs

None of these always breaks the budget on its own. Together, they absolutely can. Home ownership has a funny way of turning one trip to Bunnings into four trips and a new respect for how expensive "just a few bits" can be.

A simple way to budget the full amount

If you are trying to work out what you really need before buying, do it in this order:

1. Work out your likely borrowing limit with the Borrowing Capacity Calculator.
2. Choose a realistic purchase price, not the fantasy number you reached after five minutes on realestate.com.au.
3. Set your deposit target, for example 5%, 10% or 20%.
4. Add stamp duty based on your state and eligibility.
5. Add legal, inspection, lender and insurance costs.
6. Add a moving and immediate-repairs buffer.

That last buffer matters. Settling with exactly $14.27 left over might look heroic in a spreadsheet, but in real life it is a stress factory.

So how much extra do you actually need?

There is no honest one-size-fits-all answer because the difference between one state, one price point and one loan structure versus another can be enormous. But the principle is simple: do not stop at the deposit.

If you are saving for your first home, your real target is:

Deposit + duty + legal + inspections + lender costs + insurance + moving buffer

That is the number that gets you through settlement without drama. Or at least without unnecessary drama. Property will always provide some drama for free.

The bottom line

The purchase price gets the attention, but the side costs decide whether a deal is actually affordable. First home buyers who plan only for the deposit often end up stretched or scrambling. Buyers who budget for the full stack arrive at settlement calmer, with fewer nasty surprises and less reliance on luck.

Before you fall in love with a property, fall in love with the numbers first. It is not romantic, but it is cheaper.
