Why Purchasing Power Matters More Than Popularity in Property Markets

One of the most common misunderstandings I see in property investing is the belief that price growth itself is the signal.

A suburb goes up sharply. Headlines follow. Social media lights up. And suddenly the assumption becomes: this must be a great long-term market.

But price movement on its own doesn’t tell you why a market is rising — or whether it can keep doing so.

For that, you need to look underneath the surface.

You need to look at purchasing power.

What I Mean by Purchasing Power

Purchasing power isn’t just about current prices or median incomes.

It’s about a market’s capacity to absorb higher prices over time without stalling.

That capacity comes from:

• Household incomes that can grow
• Access to accumulated wealth (equity, business income, inheritances)
• Depth of buyers who can stretch when they choose to.

Markets with strong purchasing power don’t just rise — they re-rate.

They reset what buyers are willing and able to pay, cycle after cycle.

Popularity Can Rise Faster Than Purchasing Power

This is where many hotspot-style markets run into trouble.

Popularity can increase quickly:

— Media attention

— Investor concentration

— Short-term affordability advantages

— Yield-focused narratives.

But purchasing power tends to change slowly.

If prices rise faster than the underlying capacity of buyers to pay more, one of two things usually happens:

— Growth stalls

— Or prices become dependent on new buyers replacing old ones.

That’s a very different dynamic from organic, owner-occupier-led demand.

Why Blue-Chip Areas Behave Differently

In established, high-demand suburbs — particularly in capital cities — something different is going on.

These markets are typically supported by:

• Higher-income households
• Dual-income professionals
• Business owners and executives
• Intergenerational wealth transfer.

Importantly, many buyers in these markets are not capped by wages alone.

They’re drawing on:

• Equity from previous properties
• Upsizing capital
• Asset-backed borrowing.

That’s why, over full property cycles, these locations tend to:

• Recover faster after downturns
• Push through price ceilings that once seemed “too expensive”
• Continue attracting buyers even as affordability tightens elsewhere.

This isn’t about exclusivity.

It’s about who still has the ability to act when conditions change.

Perth Context: Where This Shows Up Locally

In Perth, this difference is especially visible.

Markets driven primarily by:

• Local owner-occupiers
• Long-term residents
• Families upgrading rather than first-time buying

tend to show far more resilience than areas dominated by:

— Short-term investors

— Interstate capital chasing yields

— Homogeneous buyer profiles.

This is one reason I often focus on established middle-ring suburbs rather than fringe locations or purely affordability-driven plays.

The demand is broader, deeper, and more persistent.

The Problem With Full-Cycle Comparisons

One of the traps in property commentary is comparing:

— A five-year surge in one market

with

— A thirty-year average in another.

Over short windows, almost any market can outperform.

Over full cycles, purchasing power usually tells the real story.

Markets with limited income growth and elastic land supply can surge — but they often struggle to:

— Sustain momentum

— Push meaningfully higher without new demand sources

— Maintain liquidity when sentiment turns.

That doesn’t make them “bad”.

It just means they behave differently.

How This Links Back to Foundational Assets

This is why purchasing power sits at the heart of foundational property investing.

Foundational assets are chosen not because they’re cheap or popular — but because:

• There is a long queue of future buyers
• Those buyers are likely to have more capacity over time, not less
• Demand is driven by lifestyle and aspiration, not just numbers.

This thinking sits within the broader framework I use when assessing property investments.

A Practical Question to Ask

When assessing any location, I encourage clients to ask:

Who is likely to be able to pay more for this property in 10–20 years’ time — and why?

If the answer relies on:

— Ever-lower interest rates

— Continuous investor inflows

— Permanent affordability advantages

That’s worth treating cautiously.

If the answer points to:

• Growing incomes
• Accumulating wealth
• Strong owner-occupier demand

You’re likely dealing with a market built for longevity.

How This Informs My Advice to Clients

This focus on purchasing power is part of the long-term approach I take when advising clients.

It’s not about chasing what’s moving fastest.

It’s about understanding what can keep moving when conditions change.
