National home values post steepest monthly fall since 2022: what it means for first home buyers

National home values recorded their steepest monthly fall since December 2022 last month, according to Cotality's (formerly CoreLogic) Home Value Index released this week. The national index dropped 0.4% in June, dragged down by renewed weakness in Sydney and Melbourne, even as several mid-sized capitals kept growing. For first home buyers watching the market for an opening, the shift is worth understanding properly rather than reacting to the headline alone.

What the June data shows

Cotality's national Home Value Index fell 0.4% in June, its largest single-month decline in about three and a half years. Over the June quarter, combined capital city values were down approximately 1.3%, led by Sydney (down around 3.2% for the quarter, roughly 1.2% in June alone) and Melbourne (down around 2.6% for the quarter, roughly 1.0% in June). The ACT also recorded a monthly decline, off a smaller base.

The national median dwelling value now sits at approximately $937,700, with the combined capital cities median around $1,024,800 and combined regional areas around $771,600. Brisbane, Adelaide and Perth have not followed Sydney and Melbourne down. All three continued to post gains through June, meaning the national figure masks a market that is moving in genuinely different directions depending on the city.

Why values are softening in Sydney and Melbourne

A few forces appear to be compounding at once. The cash rate has sat at 4.35% since the RBA's three hikes earlier in 2026, which has squeezed borrowing capacity and made higher-priced markets like Sydney and Melbourne more sensitive to rate settings than the mid-sized capitals. Cost-of-living pressure is also weighing on household confidence to commit to a major purchase.

A further factor is the federal government's May 2026 Budget reforms to negative gearing and capital gains tax, which take effect from 1 July 2027. Some investors appear to be adjusting their buying and holding decisions ahead of that date, which can reduce competition in established-home markets, particularly in the cities where investor activity is traditionally highest.

It is worth noting that different index providers can produce different headline numbers in the same month, since each uses its own data sources and methodology. What is consistent across recent reporting, however, is that momentum in Sydney and Melbourne has clearly cooled compared to Brisbane, Adelaide and Perth.

What this means for first home buyers

A cooling market is not automatically good or bad for a first home buyer - it depends on where you are buying and how you use the conditions.

• If you are looking in Sydney or Melbourne, softer conditions may translate into less competition at inspections and more room to negotiate on price, particularly on established homes where investor demand has traditionally been strong.
• If you are looking in Brisbane, Adelaide or Perth, continued growth means waiting for a broader downturn to arrive may not pay off. Buyers in these markets may want to weigh the cost of waiting against ongoing price growth.
• A softer national print does not change loan serviceability rules or the cash rate. Your borrowing capacity is still shaped primarily by your income, expenses and the current 4.35% rate environment, not by the direction of the index.
• Whichever city you are in, a lender will still assess your application on its own merits, and working through a mortgage broker can help you compare options across lenders as conditions shift.
