Can property prices keep rising faster than incomes?

“Property prices can’t keep rising faster than incomes” is an understandable response to Australia’s housing affordability problem. A chart showing more years of income needed to buy a home tells us something important about the experience of buyers. It does not, by itself, tell us when or whether prices must fall.

The distinction matters because it is possible to be concerned about affordability and cautious on new property investment without treating the price-to-income ratio as a market timer.

In the land and economic-cycle research that informs my thinking, the scarce land beneath a home matters at least as much as the building. As infrastructure, productivity and demand change, desirable land cannot simply be manufactured in the locations people most want to live.

Affordability can adjust in difficult ways: smaller blocks, townhouses rather than detached homes, apartments or longer commutes. None of that makes the outcome fair or comfortable. It does show why prices need not return to the income multiples experienced by a previous generation for the market to keep functioning.

I remain cautious about adding investment-property exposure late in the current cycle. That caution considers leverage, liquidity and broader economic risk; it is not based solely on the claim that house prices are high relative to income.

A downturn is possible, but an affordability chart cannot tell us its timing, size or what follows. Separating the lived problem of housing affordability from a claim about the next price move leads to better questions—and more considered decisions.
