A 5% Deposit Gets You Into the Property Market Faster. But What Happens When Prices Start Falling?

Buying a first home with a 5% deposit can dramatically shorten the time needed to enter the property market.

Instead of waiting until you have accumulated a traditional 20% deposit, eligible Australians can use the Australian Government 5% Deposit Scheme to purchase with a minimum 5% contribution, while the government provides a guarantee to the participating lender. The scheme also allows eligible buyers to avoid lenders mortgage insurance. First Home Buyers

For many first-home buyers, that can make ownership possible years earlier.

But there is another side to the equation.

A smaller deposit also means starting home ownership with less equity.

And when property prices are falling, the size of that equity buffer can become extremely important.

The Reserve Bank of Australia's October 2026 Financial Stability Review says Australia's mortgage system remains resilient overall. Arrears remain low, most mortgage holders have substantial savings and equity buffers, and less than 1% of borrowers are estimated to be in negative equity. Reserve Bank of Australia

But the RBA also highlights an important distinction.

Recent buyers and borrowers who started with higher loan-to-value ratios are more exposed to falling property prices than established homeowners with substantial accumulated equity. Participants in the Australian Government 5% Deposit Scheme are included in that higher-LVR group. Reserve Bank of Australia

That makes this an especially relevant conversation for first-home buyers.

A 5% Deposit Means Starting With a Small Equity Buffer

A buyer purchasing with a 5% deposit is generally borrowing close to 95% of the property's value.

That can be completely manageable if repayments remain affordable and the borrower intends to hold the property over the long term.

But the starting equity cushion is much smaller than it would be for someone purchasing with a 20% or 30% deposit.

If the property market declines soon after settlement, that initial equity can shrink quickly.

This does not automatically create a repayment problem.

Your mortgage does not suddenly become unaffordable simply because an estimated property value falls.

But it can affect your financial flexibility.

That distinction is important.

Falling Prices Affect Equity Before They Affect Repayments

Imagine two homeowners buy similar properties.

One enters with a small deposit.

The other has accumulated substantial equity over many years.

If property values decline, both owners experience the same percentage fall in the value of the property.

But the financial impact is not the same.

The established homeowner may still have a very large equity buffer.

The recent buyer may find that most of their initial equity has disappeared.

This is one reason the RBA says recent buyers and borrowers with higher LVRs are more likely to be in negative equity than the broader mortgage population. Reserve Bank of Australia

Negative equity means the mortgage balance exceeds the property's current value.

It is not the same thing as mortgage default.

A borrower can remain in negative equity while continuing to make every repayment on time.

The RBA Says Mortgage Stress Is Still Contained

It is important not to overstate the problem.

The latest RBA review does not suggest Australia's first-home-buyer market is facing a broad arrears crisis.

In fact, the RBA says arrears among first-home buyers remain low.

It also says information from banks indicates hardship and arrears among Australian Government 5% Deposit Scheme participants remain contained. Reserve Bank of Australia

More broadly, mortgage arrears remain around pre-pandemic levels despite a modest increase during 2026.

So the strongest takeaway is not:

"5% deposit buyers are failing."

It is:

"Low-deposit buyers generally have less room for property values to fall before equity becomes constrained."

That is a much more useful distinction.

Higher-LVR Borrowers Are More Sensitive to Financial Shocks

The RBA reports that borrowers with high LVRs, high loan-to-income ratios or lower incomes tend to have higher arrears rates than other borrowers because they are more vulnerable when expenses rise, income falls or interest rates increase. Reserve Bank of Australia

Again, these groups represent only a relatively small share of Australian mortgage borrowers.

But leverage matters.

Someone who borrowed close to the full value of a property simply has less equity available to absorb a market downturn.

That can become particularly important if another financial problem occurs at the same time.

For example:

a job loss,

reduced working hours,

relationship breakdown,

unexpected medical or household costs,

or another interest-rate increase.

One risk on its own may be manageable.

Several occurring together can create much greater pressure.

The Government Guarantee Protects the Lender, Not Your Equity

This point can sometimes be misunderstood.

Under the Australian Government 5% Deposit Scheme, the government provides a guarantee to the participating lender.

The borrower is still responsible for the mortgage and all required repayments. First Home Buyers

The guarantee helps eligible borrowers obtain a loan with a smaller deposit without paying LMI.

It does not guarantee:

the property's value,

the borrower's equity,

future mortgage rates,

or the borrower's ability to refinance later.

So the scheme reduces one important barrier to entering the market.

It does not remove ordinary property-market or mortgage risk.

Why Avoiding LMI Can Still Be Valuable

That does not make low-deposit purchasing inherently unattractive.

LMI can be a significant upfront cost.

Eligible buyers using the government scheme can avoid that expense while potentially purchasing years earlier than they would if they waited to accumulate a 20% deposit. The expanded scheme also has no income caps or waitlists for eligible first-home buyers. First Home Buyers

For someone paying high rent while trying to save, entering sooner can potentially make sense.

The important question is not whether 5% is "good" or "bad."

It is whether buying with 5% is appropriate for that particular household.

A Smaller Deposit Can Change Refinancing Options Later

This is where falling property prices become particularly relevant.

Suppose another lender starts offering a materially lower mortgage rate.

An established homeowner with substantial equity may be able to refinance relatively easily, subject to normal serviceability requirements.

A recent high-LVR buyer may have fewer choices.

If the property's value has fallen, the borrower's LVR can increase.

That could affect:

available lenders,

interest-rate pricing,

refinancing eligibility,

and potentially whether additional mortgage insurance or other restrictions apply outside the government-backed arrangement.

So lower equity does not necessarily make the existing mortgage unmanageable.

It can make it harder to change mortgages.

Property Valuation Can Matter More Than Purchase Price

When refinancing, a lender generally cares about the property's current assessed value rather than simply what you paid for it.

That means two borrowers who originally bought identical homes for the same price could have different refinancing outcomes if their lenders use different valuations.

For high-LVR borrowers, even modest valuation differences can matter.

That is one reason first-home buyers should think beyond settlement day.

A mortgage needs to remain suitable not only when you buy, but also if circumstances change later.

The RBA Still Sees Australia's Mortgage System as Resilient

The broader picture remains reassuring.

The RBA says most mortgage holders retain substantial liquidity buffers, with the median borrower having enough money in offset and redraw accounts to cover more than a year of scheduled mortgage repayments at current rates. Reserve Bank of Australia

It also estimates that less than 1% of borrowers are currently in negative equity.

Even under an illustrative scenario involving a uniform 20% further fall in housing prices, the RBA estimates only around 5% of mortgages would move into negative equity. Reserve Bank of Australia

So Australia's financial system is not starting from a weak position.

The vulnerability is concentrated.

That is exactly why first-home buyers with small deposits deserve separate attention from the average homeowner.

The Scheme Also Includes Important Lending Safeguards

A 5% deposit does not mean a buyer bypasses normal lending standards.

Eligible buyers still need to satisfy the participating lender's credit policy and loan approval requirements. First Home Buyers

The RBA also notes that scheme participants were assessed using APRA's serviceability framework, which tests borrowers at an interest rate above the offered rate.

That provides an additional buffer against higher repayments. Reserve Bank of Australia

So the scheme lowers the deposit barrier.

It does not remove serviceability testing.

First-Home Buyers Historically Have Some Advantages

There is another reason the RBA does not see low-deposit scheme borrowers as a major systemic threat.

First-home buyers have historically experienced relatively favourable labour-market outcomes and stronger income growth compared with some other borrower groups.

The government guarantee also covers up to 15% of the property value for the lender if a scheme loan defaults, reducing the potential for losses to spread through the banking system. Reserve Bank of Australia

That helps explain why the RBA distinguishes between individual borrower vulnerability and systemic financial risk.

A household can be financially stretched without creating a problem for Australia's banking system.

Personal Risk and Systemic Risk Are Not the Same Thing

This is probably the most important lesson from the October Financial Stability Review.

Australia can have:

strong banks,

low overall mortgage arrears,

large household savings buffers,

and very limited negative equity

while some recent buyers still experience significant pressure.

Both things can be true.

The mortgage system can be resilient overall.

And a first-home buyer with a 95% LVR can still have fewer options if prices fall shortly after purchase.

That is why national averages should never replace individual mortgage planning.

Buying Earlier Versus Saving Longer Is a Real Trade-Off

A first-home buyer deciding whether to purchase with 5% or wait for a larger deposit faces a genuine trade-off.

Buying earlier can mean:

entering the property market sooner,

avoiding additional years of rent,

potentially participating in future property growth,

and avoiding LMI through the government scheme.

Waiting can mean:

building a larger equity buffer,

potentially accessing sharper mortgage pricing,

reducing repayments,

and creating more protection if property values fall.

Neither strategy is automatically correct.

The right decision depends on the buyer's income, job stability, savings after settlement, property choice, borrowing capacity and longer-term plans.

Do Not Use Every Dollar You Have for the Deposit

A buyer may technically have enough money to meet the minimum deposit requirement.

That does not necessarily mean putting every available dollar into the purchase is sensible.

Home ownership brings additional costs.

There can be:

conveyancing,

building and pest inspections,

moving costs,

insurance,

council rates,

strata costs,

maintenance,

repairs,

and unexpected expenses.

Maintaining an emergency buffer after settlement can therefore be extremely valuable.

A larger deposit is helpful.

But liquidity matters too.

Stress-Test the Mortgage Before You Buy

A useful question for a first-home buyer is not simply:

"Can the bank approve me?"

Instead ask:

"Would I still feel comfortable with this mortgage if something changed?"

That might mean testing the budget against:

higher mortgage rates,

lower household income,

unexpected property expenses,

or temporarily reduced working hours.

The RBA's latest review shows why these buffers matter even when the financial system overall remains strong.

Falling House Prices Are Not Automatically Good News for First-Home Buyers

A weaker property market can create opportunities.

Purchase prices may become more negotiable.

Competition may decrease.

Buyers can sometimes take more time to make decisions.

But lower prices do not automatically mean lower financial risk.

If you are purchasing with a small deposit, falling property values can reduce your equity almost immediately.

At the same time, higher interest rates can reduce borrowing capacity and increase repayments.

That is why first-home buyers should evaluate the whole lending position rather than focus solely on the sale price.

A 5% Deposit Gets You Into the Property Market Faster. But What Happens When Prices Start Falling?

The Australian Government 5% Deposit Scheme can be an extremely useful pathway into home ownership.

It lowers the deposit barrier.

It can remove LMI for eligible borrowers.

And it can help buyers enter the market sooner. First Home Buyers

But buying sooner also means potentially starting with a much smaller equity buffer.

The RBA's October Financial Stability Review makes clear that Australian mortgage borrowers remain resilient overall, while also highlighting that recent and high-LVR buyers are more exposed when property prices decline. Reserve Bank of Australia

For first-home buyers, the lesson is not to avoid a 5% deposit.

It is to understand what comes with it.

Considering Buying With a 5% Deposit?

Loan & Own Mortgages works with first-home buyers to understand deposits, borrowing capacity, pre-approval and suitable lending pathways. LNO Mortgages also compares options across a panel of more than 50 lenders, subject to eligibility.

Before deciding how much deposit to use, it can be worth reviewing the complete position: your expected repayment, savings remaining after settlement, LVR, lender policy and how comfortable the mortgage would remain if rates or property values changed.

The goal should not simply be getting into the market as quickly as possible.

It should be getting into the market with a mortgage you can continue to manage.
