Over the past three years, we have experienced a marked increase in conversations with property investors considering their retirement and how their property will fund that retirement. This ultimately leads to the big question…

“Should I start selling?”

A keen-eyed client who also noticed this trend coined it the Silver Wave.

For decades, residential property has been a cornerstone of retirement planning. Investors accumulated portfolios through a combination of rental income, leverage, tax advantages, and, most importantly, capital growth. The assumption was often simple: hold long enough and the market would do much of the heavy lifting.

However, retirement changes the equation.

A retiree’s priorities are often liquidity, certainty of income, simplicity, and reduced risk. A portfolio that looked attractive during the accumulation phase may be less appealing when an investor wants access to cash, wishes to reduce debt, or simply no longer wants the responsibilities that come with being a landlord.

If a meaningful proportion of ageing investors reach the same conclusion, the market could experience a gradual but persistent increase in supply over many years.

This raises an interesting question: what impact could the Silver Wave have on future property returns?

The Yield Challenge

One concern is that many residential investment properties currently offer relatively modest yields.

In Auckland and Wellington, gross rental yields of 3–4% remain common, with net yields often materially lower once rates, insurance, maintenance, and management costs are considered. Some commentators estimate average net yields around 2–3%, meaning that many properties still rely heavily on future capital growth to generate attractive overall returns.

If property values enter a prolonged period of subdued growth due to increased supply from retiring investors, the investment equation changes significantly.

An investor earning a 2–3% net yield while paying mortgage interest rates above that level may find themselves effectively going backwards on a cashflow basis. Even debt-free investors may begin comparing those returns with alternative investments offering greater liquidity and comparable or higher income.

 The Tax Environment Has Changed

The tax landscape has also evolved.

Property investors have been under attack through tax legislation for many years, from the removal of depreciation on buildings, ring fencing of rental losses, interest limitations and of course the constant threat of property specific capital gains tax.

The Capital Gains Question

The possibility of a property-focused capital gains tax continues to surface in political debate, particularly ahead of elections.

Whether such policies are ultimately implemented is impossible to predict. However, investment decisions are often driven as much by expectations as reality.

For some investors, the mere possibility of future taxation may accelerate decisions that were already being contemplated for retirement purposes.

The Contrarian View

Of course, there is another side to the argument.

Every seller requires a buyer.

Periods of weak sentiment have historically created opportunities for investors prepared to take a long-term view. If a wave of retiring investors increases supply and moderates price growth, new investors may gain access to assets that were previously difficult to acquire.

The Silver Wave may therefore not represent a collapse in property values. Instead, it may signal a transition from a market driven primarily by capital gains toward one where income, cashflow, and asset selection become increasingly important.

A Different Conversation

Perhaps the most important question is not whether property will rise or fall.

It is whether an investor’s portfolio remains aligned with their stage of life.

For those approaching retirement, now may be the time to review debt levels, liquidity requirements, succession plans, tax implications, structure changes and alternative investment options.

For new investors, it may be time to ask whether a quieter market creates opportunities that are difficult to see when headlines are dominated by caution. This may require more flexible long-term structures that can adapt to changes in tax legislation or handle property that is focused on income generation rather than capital gains.

The Silver Wave is not necessarily a reason to panic, nor is it a reason to rush into the market.

But it is a reminder that property cycles are influenced not only by interest rates and economic policy, but also by demographics. And demographics can be powerful forces.

The next decade may not belong to the investor who owns the most property. It may belong to the investor who understands when to hold, when to sell, and how to adapt as the market evolves. If you are thinking about retirement, succession, or your next investment move, now is the time to start that conversation.
