Australian housing values fell for a sixth consecutive month in September 2026. For first home buyers, that can mean more homes to compare and more room to negotiate. It does not automatically mean a home is easier to afford.
Cotality’s September report puts the national monthly decline at 1.1%. The useful question for a buyer is how those changing conditions affect their budget, property search and ability to hold onto a home after buying it.
Cotality’s Home Value Index tracks changes in housing values. Its national result describes a broad trend, rather than the price change of every individual home.
In its report published on 1 October 2026, Cotality recorded September falls of 1.5% in Brisbane, 1.4% in Sydney and 0.7% in Melbourne. Darwin rose 0.4%.
National values were 5.2% below their March 2026 record high, but unchanged compared with a year earlier. Those figures measure different periods: recent falls can follow earlier gains. Buyers still need evidence about the suburb, property type and home they are considering.
Homes are taking longer to sell, leaving more properties available for buyers to compare. Cotality reported capital city homes taking a median of 39 days to sell, compared with 23 days a year earlier. The median is the middle result, not a deadline for every seller.
Total advertised stock across the capitals was 23.1% higher than a year earlier, even though fewer fresh listings were entering the market. Properties were accumulating because sales had slowed.
That can create more breathing room for inspections, research and price negotiation. A longer listing does not prove a seller will accept a large discount. A sound offer still needs support from comparable sales.
A lower purchase price can reduce the deposit and loan required. Repayment comfort also depends on interest rates, household expenses and the loan arrangement.
Consider a hypothetical example. A home costs $600,000, and a buyer contributes a 20% deposit of $120,000, leaving a $480,000 loan. At $570,000, the same deposit percentage requires $114,000 and leaves a $456,000 loan.
That is $6,000 less for the deposit and $24,000 less to borrow. These figures exclude buying costs and are not a prediction for any particular property.
With the same interest rate and loan term, the smaller loan would reduce repayments. But the buyer still needs to budget for inspections, conveyancing, applicable duties and fees, insurance, rates and maintenance. A cheaper home can still stretch a household.
A prepared first home buyer needs a comfortable budget, evidence about value and room for unexpected costs. Run these checks before negotiating:
The September report shows a falling market; it does not identify the bottom or establish the right buying date for a household.
Buying may suit someone with stable finances, a suitable home and repayments they can sustain. Waiting may be sensible when savings are thin, employment is uncertain or available properties do not fit their needs.
Either choice should account for further value falls. Buyers expecting to move or sell soon need to weigh that risk alongside buying and selling costs.
First home buyers can use softer conditions to improve their research and buying discipline. Start by setting a repayment limit, confirming borrowing options and comparing suitable properties against recent sales.
For someone considering an investment first, add realistic rent, vacancy and holding costs to those checks. Falling values alone do not make an investment sound.
Use the market data to ask better questions, then make a decision the household can sustain.
