Interest rates are one of the most important factors influencing Australia’s property market. When borrowing costs rise, the effect can extend beyond mortgage repayments, influencing how much buyers can borrow, how much they are willing to pay, and ultimately how property prices perform.

This relationship is particularly important in the current Australian property market. In “The CEO Breakdown” episode, Latitude Accountants’ John Saade discussed the possibility of another Reserve Bank of Australia (RBA) interest rate increase and the potential pressure this could place on homeowners and property values.

The Australian housing market was already experiencing a correction, with Sydney and Melbourne among the markets under the greatest pressure. Higher interest rates could add another layer of pressure by reducing borrowing capacity and weakening buyer demand.

But how exactly do interest rates affect property prices, and what does this mean for Australian homeowners and investors?

How Do Interest Rates Affect Property Prices?

The relationship between interest rates and property prices is largely driven by borrowing capacity and demand.

When interest rates rise, mortgage repayments generally become more expensive. For a buyer with a fixed income, this can mean they can no longer comfortably afford the same loan amount.

As borrowing capacity falls, buyers may need to:

• Reduce their property budget
• Delay purchasing
• Look in less expensive areas
• Borrow less
• Increase their deposit
• Compete for fewer properties within their budget

When enough buyers reduce their purchasing power, demand can weaken.

If sellers are still expecting prices from a stronger market, properties may take longer to sell, and sellers may need to negotiate more aggressively.

Over time, this can contribute to downward pressure on property prices.

Why Higher Mortgage Rates Can Reduce Borrowing Capacity

One of the most direct effects of higher interest rates is an increase in the cost of servicing debt.

Consider two buyers with identical incomes and deposits. If mortgage rates rise, the buyer’s potential repayments increase even though their income has not changed.

This can reduce the amount a lender is prepared to provide.

For example, a household that could previously afford a $900,000 loan may find that higher repayments make that level of borrowing unsuitable or unavailable under current lending assessments.

The result is a reduction in the amount that some buyers can spend on property.

This does not mean every buyer’s borrowing capacity falls by the same amount. Income, existing debt, expenses, deposit size and lender assessment criteria all matter.

What Is Happening With Australian Interest Rates?

Interest rates have become an important issue in the current property correction.

In the CEO Breakdown discussion, John Saade highlighted economic data that had increased expectations of another RBA rate rise. Stronger-than-expected GDP growth and elevated government borrowing costs were among the factors discussed.

At the time of the episode, financial markets had increased the probability assigned to a September rate increase, with further increases also being considered.

The key issue for property owners is not simply the exact timing of one rate decision.

It is the possibility that borrowing costs could remain elevated for longer.

How Rising Interest Rates Affect Existing Homeowners

Higher rates do not only affect people trying to buy property.

Existing homeowners with variable-rate mortgages can also face higher repayments.

For households with significant debt, an increase in mortgage repayments can reduce disposable income.

Money that might otherwise be spent on:

• Dining and entertainment
• Travel
• Household purchases
• Renovations
• New vehicles
• Other discretionary spending

may instead be directed towards servicing the mortgage.

If this occurs across a large number of households, higher interest rates can affect the broader economy as well as the property market.

What Is Mortgage Stress?

Mortgage stress can occur when housing repayments become difficult to manage relative to a household’s income and other expenses.

Higher interest rates can increase this pressure, particularly for borrowers who:

• Have large mortgages
• Have limited savings
• Have recently purchased at high prices
• Have experienced a reduction in income
• Are already facing high living costs
• Have little room in their household budget

Mortgage stress can also influence property market behaviour.

If financially pressured homeowners need to sell, they may be more willing to accept a lower offer to complete the sale quickly.

However, a rise in interest rates does not automatically mean widespread forced selling. Household financial circumstances vary significantly.

How Interest Rates Can Affect Buyer Confidence

Property markets are influenced by psychology as well as financial calculations.

When buyers hear that interest rates may rise again, some may become more cautious about taking on a large mortgage.

Others may decide to wait and see what happens to prices.

This can reduce competition, particularly when buyers are already concerned about the possibility of further price falls.

In a market where fewer people are bidding at auctions and properties are taking longer to sell, sellers may have less negotiating power.

This can contribute to a buyer’s market.

The Negative Wealth Effect

Another issue discussed by John Saade is the negative wealth effect.

When property values decline, homeowners may feel less wealthy because the value of one of their largest assets has fallen.

This can influence consumer confidence and spending decisions.

For example, a homeowner who sees the value of their property decline may become more cautious about taking on additional debt or making large purchases.

Combined with higher mortgage repayments, this can create a double pressure:

Higher borrowing costs + lower perceived household wealth = greater financial caution.

This is one reason property market corrections can have effects beyond the housing sector.

Do Higher Interest Rates Always Cause Property Prices to Fall?

Not necessarily.

Interest rates are an important factor, but they are not the only factor determining property prices.

Other factors include:

• Employment
• Population growth
• Migration
• Housing supply
• Construction activity
• Household incomes
• Investor demand
• Government policy
• Local infrastructure
• Consumer confidence

For example, strong employment and population growth can support housing demand even when borrowing costs are higher.

This is why it is difficult to say that a particular interest-rate increase will automatically result in a specific percentage decline in property prices.

Why Different Australian Markets Can Respond Differently

Australia does not have one uniform property market.

Sydney, Melbourne, Brisbane, Perth, Adelaide and Darwin can all experience different conditions at the same time.

The same is true at a suburb level.

One suburb may have strong employment opportunities, limited housing supply and high demand, while another may have weaker demand and a large amount of available stock.

As a result, buyers and investors should avoid assuming that a national property forecast will accurately describe the property they are considering.

What Does This Mean for Property Buyers?

Higher interest rates can make purchasing property more difficult, but they can also change the balance of power between buyers and sellers.

When borrowing capacity falls and buyer demand weakens, sellers may become more willing to negotiate.

This can create opportunities for buyers who have:

• A strong deposit
• Stable income
• Manageable existing debt
• Sufficient cash reserves
• A clear purchasing strategy
• The ability to negotiate

Rather than focusing solely on whether interest rates will rise or fall, buyers should determine whether they can comfortably afford the property under different interest-rate scenarios.

What Should Property Investors Consider?

Property investors need to consider both the property itself and the cost of financing it.

A property may appear attractive based on its purchase price or expected capital growth, but higher interest costs can significantly affect cash flow.

Before purchasing, investors should consider:

Mortgage Costs

Calculate repayments based on realistic interest-rate assumptions rather than relying solely on the current rate.

Rental Income

Consider whether expected rent is sufficient to help cover mortgage repayments and other ongoing expenses.

Cash Flow

Allow for rates, insurance, maintenance, property management and potential periods without a tenant.

Tax and Structure

Consider how the property will be owned and how the investment may interact with your broader tax position.

Professional advice can be particularly valuable before making major structural or investment decisions.

Should You Wait for Interest Rates to Fall?

Waiting for interest rates to fall may seem logical, but there is no guarantee that rates will decline quickly or that property prices will remain unchanged while you wait.

If rates eventually fall, lower borrowing costs could increase buyer demand and potentially put upward pressure on property prices.

On the other hand, if rates remain high, waiting could provide more time to build savings, reduce debt, and improve financial resilience.

The right decision depends on your individual circumstances.

Rather than trying to predict the exact timing of the next rate move or property-market bottom, consider whether you can comfortably manage the purchase under current conditions.

How Can Homeowners Prepare for Higher Interest Rates?

Homeowners concerned about rising rates can review their household finances and identify areas where they can improve their financial buffer.

This may include:

• Reviewing household expenses
• Reducing unnecessary debt
• Building an emergency fund
• Reviewing loan options with an appropriately licensed professional
• Understanding current mortgage repayments
• Avoiding excessive additional borrowing
• Reviewing longer-term financial goals

The objective is to make the household less vulnerable to unexpected changes.

Final Thoughts

Interest rates can have a significant influence on Australia’s property market because they affect borrowing capacity, mortgage repayments and buyer demand.

John Saade’s discussion of another potential rate rise highlights why interest rates remain an important consideration during the current property correction.

However, interest rates alone do not determine property prices.

Employment, supply, demand, population growth, household finances, and local market conditions all play a role.

For buyers and investors, the most important question is therefore not simply whether rates are going up or down.

It is whether the property purchase remains financially sustainable under realistic conditions.

A falling market may create opportunities, but buyers should make decisions based on affordability, cash flow and long-term objectives rather than attempting to perfectly predict the next interest-rate move.

Frequently Asked Questions About Property Prices and Interest Rates

Do rising interest rates cause property prices to fall?

Rising interest rates can put downward pressure on property prices by increasing mortgage costs and reducing borrowing capacity. However, other factors such as employment, housing supply, and population growth also influence property prices.

Why do higher interest rates reduce property prices?

Higher rates generally increase mortgage repayments and reduce the amount buyers can afford to borrow. This can weaken demand and reduce the prices some buyers are willing or able to pay.

How do interest rates affect borrowing capacity?

When mortgage rates increase, lenders generally assess whether borrowers can afford higher repayments. This can reduce the amount a buyer is able or willing to borrow.

What happens to homeowners when interest rates rise?

Homeowners with variable-rate mortgages may face higher repayments. This can reduce disposable income and increase financial pressure, particularly for households with large debts.

Can property prices fall even if employment remains strong?

Yes. Employment is one factor supporting housing demand, but property prices can still decline due to higher interest rates, reduced borrowing capacity, weaker confidence or other market conditions.

Should I buy property if interest rates are rising?

It can still make sense to buy if the property is appropriately priced and the purchase is affordable under realistic interest-rate scenarios. Buyers should consider their financial position and long-term objectives rather than relying on a market forecast.

Should I speak to an accountant before buying an investment property?

An accountant can help you assess the potential tax, cash-flow and structural considerations associated with an investment property and how the purchase may fit into your broader financial position.
