How Much Deposit Do You Need for an Investment Property in Australia?

The tidy textbook answer is 20 percent of the purchase price, plus buying costs. That’s the benchmark plenty of investors work toward because borrowing above 80 percent of the property value may trigger Lenders Mortgage Insurance, or LMI.

But the real answer is a bit more useful than that.

Your deposit is only one part of the investment picture. You also need to allow for stamp duty or transfer duty, legal fees, inspections, loan costs, insurance, vacancy, repairs, and an actual cash buffer after settlement. Miss that part and a property that looked “affordable” five minutes ago can become a proper nuisance the moment something normal goes wrong.

And something normal usually does.

From a buyer’s agent perspective, I don’t see the deposit as the finish line. I see it as the starting point for the investment brief. Your deposit helps shape what market makes sense, what asset type is realistic, how much risk you can carry, and whether the property will still feel manageable once the excitement wears off.

For first-time investors, the better question isn’t just, “Do I have enough deposit?”

It’s, “Do I have enough deposit, enough buffer, and enough strategy to buy the right property without stretching myself into something silly?”

That’s the question worth answering.

Quick version

A sensible starting point for many Australian property investors is:

• around 20 percent deposit if you want to reduce the chance of paying LMI, subject to lender policy
• purchase costs on top, including transfer duty, legal fees, inspections and loan costs
• a cash buffer for vacancy, repairs, rates, insurance, maintenance and rate movement
• pre-approval before you start taking listings too seriously
• a strategy that fits the budget, because what you can borrow is not always what you should spend

A lender may approve you for a number. That doesn’t mean you should immediately sprint into the market waving a pre-approval around like you’ve won a meat raffle.

The better question is simple:

What can I safely buy, safely hold, and still live a normal life if something goes wrong?

Because something usually does.

That’s not pessimism.

That’s property.

The 20 percent deposit benchmark

In Australia, many investors aim for a 20 percent deposit because borrowing more than 80 percent of the property’s value may mean paying Lenders Mortgage Insurance.

That’s why the 20 percent benchmark gets talked about so much. It can reduce lender risk, improve flexibility, and sometimes make the whole lending picture cleaner.

Here’s what that looks like at a basic level.

Purchase price	20% deposit	Loan amount before costs
$600,000	$120,000	$480,000
$700,000	$140,000	$560,000
$800,000	$160,000	$640,000
$900,000	$180,000	$720,000
$1,000,000	$200,000	$800,000

That table is clean.

Real life isn’t.

The deposit is only the deposit. It doesn’t cover transfer duty, conveyancing, inspections, loan costs, insurance, buyer’s agent fees, initial repairs or the buffer you should still have after settlement.

That’s where investors get caught out. They hit the deposit target, think they’re nearly there, and then the real buying costs turn up, clear their throat, and ruin the mood.

So yes, 20 percent is a useful benchmark.

No, it isn’t a magic number.

A 20 percent deposit doesn’t make a bad property good. A 10 percent deposit doesn’t automatically make a good property bad. The real issue is whether the whole investment still works once finance, costs, risk and holding pressure are properly factored in.

What is loan-to-value ratio?

Loan-to-value ratio, usually shortened to LVR, is the size of the loan compared with the value of the property.

If you buy a $700,000 property and borrow $560,000, the LVR is 80 percent.

Purchase price	Deposit	Loan amount	Approx. LVR
$700,000	$140,000	$560,000	80%
$700,000	$105,000	$595,000	85%
$700,000	$70,000	$630,000	90%

The higher the LVR, the more you are borrowing relative to the property’s value.

That can help you get into the market earlier, but it can also mean higher repayments, potentially higher costs, less equity buffer, and less room if the property’s value falls.

Leverage is one of the reasons property can work so well over time.

It’s also one of the reasons mistakes can sting.

Used well, debt can help you buy a quality asset sooner.

Used badly, debt can turn a mediocre purchase into a very expensive life lesson with a monthly direct debit attached.

I’m not anti-debt.

Property investing usually involves debt.

I’m anti-casual debt.

There’s a difference.

What is Lenders Mortgage Insurance?

Lenders Mortgage Insurance, or LMI, is insurance that protects the lender if the borrower defaults and the property sale doesn’t fully cover the loan.

That’s the key bit.

LMI protects the lender, not the borrower.

Investors often react to LMI as if it’s automatically evil. I don’t think it’s that simple.

Sometimes LMI is just the price of entering the market sooner. That may be perfectly reasonable if the asset is strong, the holding position is comfortable, and waiting would mean missing a genuinely good opportunity.

Sometimes it’s just the price of impatience.

That’s a very different thing.

The better question isn’t:

Is LMI good or bad?

It’s this:

Am I paying LMI to buy a strong asset earlier, or am I paying it to stretch into something that barely works on day one?

That’s where the distinction matters.

Buying earlier can be smart.

Buying stretched usually isn’t.

People confuse those two things all the time.

Deposit is not the same as total cash required

This is the bit I really want first-time investors to understand.

Your deposit is not your total buying cost.

You may also need to allow for:

• transfer duty or stamp duty
• legal or conveyancing fees
• building and pest inspections
• strata report if you’re buying strata property
• loan application or valuation fees
• mortgage registration fees
• buyer’s agent fees
• landlord insurance
• building insurance where relevant
• settlement adjustments
• initial repairs
• property management setup
• vacancy buffer
• maintenance buffer
• emergency cash reserve

This is where spreadsheet investing gets a bit silly.

The spreadsheet assumes the rent arrives every week, the tenant never leaves, the roof behaves itself, insurance stays sensible and the property never has a bad day.

Property has bad days.

Sometimes the roof has one.

Sometimes the tenant has one.

Sometimes the strata committee has one and sends everyone a special levy for the privilege.

A proper investment budget allows for the annoying bits.

Not because you’re negative.

Because you’re serious.

A practical example: the $800,000 investment property

Let’s say you want to buy an investment property at $800,000.

If you use a 20 percent deposit, the simple version looks like this:

• purchase price: $800,000
• deposit: $160,000
• loan amount: $640,000
• approximate LVR: 80 percent

But that’s not the full cash picture.

You may also need to allow for:

Cost item	Comment
Transfer duty	Varies by state or territory
Conveyancing or legal fees	Needed for contract and settlement
Building and pest inspection	Essential for houses and many townhouses
Strata report	Essential for units, villas and strata townhouses
Loan costs	Varies by lender and structure
Insurance	Building, landlord and other relevant cover
Buyer’s agent fee	If using professional acquisition support
Initial repairs	Almost always underestimated
Cash buffer	Critical for vacancy, repairs and holding risk

That’s why two investors with the same headline deposit can have completely different buying power.

One investor may have enough for the deposit and another $60,000 sitting there for costs and buffer. Another may have just enough to scrape across the line and nothing left once the dust settles.

Those are not the same position.

The second investor may still be able to buy, but the brief probably needs to be more conservative. Lower maintenance risk. Better rental support. More liquidity. Less tolerance for nasty surprises.

That’s how deposit connects directly to property selection.

It’s not just a finance issue.

It’s an acquisition issue.

Why stamp duty changes the equation

Transfer duty, commonly called stamp duty, is one of the biggest upfront buying costs in Australia.

For investors buying nationally, it matters a lot because it varies by state and can materially change the amount of cash required to buy the same-priced property.

An $800,000 budget does not behave the same way everywhere.

The purchase price might be identical, but the real acquisition cost can look very different depending on the state, title type, buyer category and related holding costs.

Before buying, investors should ask:

• what is the transfer duty in that state?
• are there investor surcharges?
• are there land tax implications?
• are there foreign buyer rules if relevant?
• what are the ongoing holding costs?
• does the deal still stack up once all costs are included?

This is one of the reasons I get a bit wary when people say, “Just buy where it’s cheaper.”

No.

Buy where the total investment case makes sense.

Cheaper is not a strategy. It’s just a lower number.

Sometimes cheaper is excellent value. Sometimes cheaper is the market quietly telling you demand is thinner, risk is higher, or resale depth is weaker.

Your job is to know which one you’re dealing with before you sign anything.

Should you buy with less than 20 percent deposit?

Possibly.

But it depends on the broader position, not just the deposit percentage.

Buying with less than 20 percent may be worth considering if:

• your income is strong and stable
• your broker confirms the structure works
• you still keep a cash buffer after settlement
• the property has strong fundamentals
• the rent supports the holding position
• the market has genuine demand
• LMI is understood and accepted as part of the strategy

It may be risky if:

• you have no real buffer after settlement
• the property has weak tenant appeal
• the asset needs repairs straight away
• cash flow is already tight
• the market has poor resale depth
• you are buying because of FOMO
• one vacancy would create financial stress

This is where I’m happy to be blunt.

If a 10 percent deposit gets you into a genuinely strong asset while still leaving room to breathe, it may be a reasonable path.

If a 10 percent deposit gets you into something that only works if nothing goes wrong, that’s not investing.

That’s hoping.

And hope is not a holding strategy.

The hot water system does not care about your optimism.

Should you wait until you have 20 percent?

This is where investors get stuck between patience and action.

Waiting until you have 20 percent may help you:

• reduce borrowing pressure
• potentially avoid LMI
• improve your buffer
• strengthen the lender position
• negotiate with more confidence
• reduce stress once you own the property

But waiting can also mean:

• prices move while you save
• borrowing capacity changes
• lending rules shift
• rents and living costs rise
• you lose time in the market

There’s no universal answer.

The practical approach is to compare scenarios properly.

Ask your broker to model:

• buying now with a smaller deposit
• waiting 6 to 18 months to save more
• using equity if available
• buying at a lower price point
• targeting a different city or asset type
• keeping more cash aside and spending less

Then look at what each scenario actually buys.

This is where a buyer’s agent view helps. The finance model might say you can buy up to $850,000. The property market might tell you the better-quality investment stock is actually around $760,000 in a different city.

More spending doesn’t automatically mean better buying.

Sometimes the smartest investor in the room is the one who doesn’t max out the approval.

Can you use equity as a deposit?

Yes. Plenty of investors use equity in an existing property to help fund an investment purchase.

Equity is simply the difference between what a property is worth and what is owed on it.

For example:

Estimated property value	Loan owing	Total equity
$1,400,000	$850,000	$550,000

But total equity is not the same as usable equity.

A lender may only allow you to access part of that amount depending on valuation, income, existing debts, serviceability, property type and lender policy.

Using equity can be useful because it may allow you to buy without saving the full deposit in cash from scratch.

But equity isn’t free money.

It’s debt.

And because it may be secured against an existing property, it needs to be handled properly.

Used well, equity can help you build a portfolio.

Used badly, it can increase risk across the whole household balance sheet.

From an acquisition point of view, I want to know whether the investor is using equity to buy a strong asset, or using equity to make a weak decision look possible.

Those are not the same thing.

Speak to a broker or lender first. Then speak to your accountant and legal adviser about structure.

The property search should come after that.

Not before.

Your deposit should shape the property strategy

This is the bit that often gets missed.

Your deposit doesn’t just determine whether you can buy.

It helps determine what you should buy.

A smaller deposit may push the brief toward:

• lower purchase price
• stronger rental support
• lower maintenance risk
• less renovation risk
• lower vacancy risk
• more conservative acquisition
• better holding comfort

A larger deposit may allow more flexibility around:

• stronger growth locations
• better land component
• houses or townhouses instead of units
• lower yield but better long-term demand
• tighter-supply suburbs
• lower LVR and less cash-flow pressure
• value-add potential

Neither position is automatically better.

The point is that they produce different briefs.

A $100,000 deposit and a $300,000 deposit should not lead to the same search strategy. They may point to different markets, different suburbs, different property types and different risk filters.

That’s why I don’t like starting an investment search with, “Which suburb is best?”

The better starting point is:

What is the investor’s capital position, borrowing position, holding capacity and objective?

Unsexy question.

Very useful.

The biggest mistake: having no margin

The most common deposit mistake isn’t always having too small a deposit.

It’s having no margin.

The investor technically has enough to buy, but not enough to hold comfortably.

They’ve got the deposit. They’ve got pre-approval. They’ve got enthusiasm. Then normal property ownership happens.

A tenant leaves.

The rent comes in lower than expected.

A roof leak shows up.

Insurance comes in high.

The strata committee announces works.

The bank valuation is conservative.

A repair bill lands two weeks after settlement, because of course it does.

None of that is exotic.

It’s normal.

If one normal problem ruins the investment, the issue usually isn’t bad luck. It’s poor planning.

That’s why I like investors to keep a sensible cash buffer after settlement. I won’t nominate a number because that moves into personal financial advice, and it depends on the investor. But from a property acquisition perspective, no buffer makes the brief fragile.

A good investment should not require everything to go perfectly.

Everything will not go perfectly.

That’s Tuesday.

How deposit affects market selection

Let’s compare two investors.

Investor A has a smaller deposit and needs stronger cash flow.

Investor B has a larger deposit, stronger income and can tolerate a lower yield in exchange for stronger long-term growth prospects.

They should not automatically buy in the same market.

Investor A may need:

• a lower entry price
• stronger rent relative to price
• lower maintenance exposure
• minimal renovation risk
• strong tenant demand
• conservative borrowing
• better liquidity

Investor B may be able to consider:

• better land component
• stronger future buyer demand
• tighter supply
• lower yield
• higher-quality established locations
• more long-term growth orientation
• value-add potential

This is why generic hotspot lists are dangerous.

They don’t know your deposit.

They don’t know your borrowing capacity.

They don’t know your income stability.

They don’t know whether you can handle a vacancy.

And they definitely don’t know whether you’re the sort of person who panics when a dishwasher breaks.

A good investment brief starts with the investor and then moves to the market.

Not the other way around.

Should your first investment property be cheaper?

Not automatically.

Cheaper can be useful if it improves your buffer, reduces borrowing pressure and still gives you access to a quality asset in a sound market.

But cheaper can also mean:

• weaker tenant demand
• poorer resale depth
• lower household incomes
• higher maintenance risk
• higher insurance risk
• limited capital growth
• compromised location
• weak land value
• too much investor-owned stock

Expensive is not automatically better either.

A higher-priced property can mean weaker yield, higher debt exposure, higher holding costs and more pressure if life gets expensive.

Price is not the strategy.

Value is price relative to quality, scarcity, demand, risk and future resale.

For a first investment property, the right price point is the one that lets you buy a good asset, hold it safely, and stay aligned with the broader plan.

That might be $650,000.

It might be $850,000.

It might be more.

The number matters less than the fit.

A practical deposit planning checklist

Before you get serious, work through this properly.

Finance

• Have you spoken to a broker or lender?
• Do you understand your borrowing capacity?
• Do you know your likely repayments?
• Have you tested higher-rate scenarios?
• Do you know whether LMI applies?
• Do you understand the proposed loan structure?

Cash position

• Do you know your actual deposit amount?
• Have you allowed for purchase costs?
• Have you checked transfer duty in the target state?
• Will you still have cash after settlement?
• Have you allowed for vacancy and repairs?

Strategy

• Are you chasing growth, yield or balance?
• Does the deposit support that strategy?
• Does your income support the holding cost?
• Would another market buy a better asset for the budget?

Property selection

• What asset type suits the deposit?
• What risks need to be excluded?
• What rental evidence do you need?
• What comparable sales are relevant?
• What inspections and due diligence need to happen?

If you can’t answer those questions yet, that’s fine.

It just means you’re not ready to make offers.

Far better to discover that now than when you’re emotionally attached to a listing with nice photos and a suspiciously enthusiastic agent.

Parker Hadley’s view: deposit first, property second

When we work with investors, I don’t want to start with a listing.

I want to start with the investor’s position.

That means understanding:

• deposit
• borrowing capacity
• income stability
• cash buffer
• risk tolerance
• investment goal
• time frame
• state flexibility
• asset type suitability
• tolerance for maintenance or renovation risk

Then we build the acquisition brief.

For national investors, the deposit helps narrow the search properly. A $700,000 budget might point us to one set of markets and asset types. A $1 million budget might open up something different. A smaller deposit may mean yield and holding cost matter more. A larger deposit may allow a more growth-focused brief.

There’s no shame in any of those positions.

The problem is pretending they’re all the same.

The deposit is a constraint, and good constraints are useful. They stop you wandering into the wrong part of the market with a pre-approval letter and a dream.

FAQs

How much deposit do I need for an investment property in Australia?

Many investors aim for a 20 percent deposit plus purchase costs because borrowing above 80 percent of the property value may trigger Lenders Mortgage Insurance depending on lender policy and borrower circumstances.

Some investors buy with less, but they need to understand the costs, risks and cash-flow impact before doing it.

Can I buy an investment property with a 10 percent deposit?

Possibly, depending on lender policy and your position.

But that may mean higher borrowing costs, LMI, stricter assessment and less equity buffer. The real question is whether buying with a 10 percent deposit still leaves enough room to hold the property safely after settlement.

Is a 20 percent deposit always best?

Not always.

A 20 percent deposit may reduce lender risk and help avoid LMI, but waiting to save it may also delay your investment. The right decision depends on the property, market, income, buffer and loan structure.

What costs do I need besides the deposit?

Transfer duty, legal fees, inspections, loan costs, insurance, settlement adjustments, buyer’s agent fees, repairs, vacancy and a cash buffer.

The deposit alone is not the full buying cost.

Can I use equity instead of a cash deposit?

Yes. Some investors use equity from an existing property to help fund an investment purchase.

But equity is borrowed money, not free money, and it needs to be handled carefully.

Should I buy interstate if my deposit isn’t enough for my local market?

It can make sense if your budget buys a better investment asset elsewhere.

But don’t buy interstate just because it looks cheaper. You still need proper fundamentals, tenant demand, local inspection, due diligence and a clear strategy.

Does my deposit affect what type of property I should buy?

Yes.

A smaller deposit may push you toward a more conservative brief with stronger rental support and lower maintenance risk. A larger deposit may allow more flexibility around market, location, asset type and growth profile.

Should I speak to a broker before a buyer’s agent?

Usually, yes.

A broker helps confirm borrowing capacity, loan structure and lender options. A buyer’s agent then helps turn that finance position into a property strategy and acquisition brief that actually fits the market.

Conclusion

So, how much deposit do you need for an investment property in Australia?

A sensible benchmark is 20 percent plus purchase costs, particularly if you want to reduce the chance of paying LMI. But the real answer depends on borrowing capacity, risk tolerance, cash buffer, strategy, market and asset type.

The deposit matters.

It just isn’t the whole game.

A good investor needs enough money to buy, enough buffer to hold, enough discipline to avoid weak assets, and enough strategy to choose the right market in the first place.

The bank may tell you what you can borrow.

The better question is what you should buy.

That’s where the real work starts.
