Should NZ Property Investors Sell Right Now?

The realestate.co.nz data for April makes grim reading if you hold investment property. Listing stock at a 12-year high. Asking prices declining. The stock-to-sales ratio is giving buyers leverage they haven't had since the GFC years.

I've been turning this over for one of my own properties - a 3-bedroom that is harder to fill than my others and increasingly less lucrative. That thinking forced me to work through the full picture, not just the uncomfortable parts. Here is where I ended up.

The yield maths

Take a realistic example: a 3-bedroom in Auckland's middle suburbs, bought for around $850K. Currently renting at $650 a week. Gross yield: 3.97%.

Subtract the fixed costs - rates ($4K), insurance ($2K), maintenance ($2-3K per year) - and net yield drops to roughly 3%. On a fixed mortgage at 5.4%, you are funding a gap of about $20K a year from other income on a 70% LVR loan. Not catastrophic if capital gain covers it long-term, but it changes character when prices are flat or declining.

The floating rate is around 5.8%, and despite the OCR sitting at just 2.25%, it is likely to rise rather than fall. Here is why: the Reserve Bank held the OCR at its April 8 decision, but the language of that decision is worth reading carefully. Conflict in the Middle East has disrupted oil and petrochemical supply through the Strait of Hormuz. Consumer price inflation was already at 3.1% in December 2025 - above the RBNZ's 1-3% target band. The Committee's own forecast puts CPI at 3.0% in Q1 2026 and 4.2% in Q2 2026. The OCR stayed put because demand is still weak and there is spare capacity in the economy. But fixed-term mortgage rates have already risen around 20 basis points since the conflict started, as wholesale market rates moved independently of the OCR.

The cutting cycle that investors hoped would continue has stalled. The Committee was explicit: if second-round effects emerge - if higher fuel costs feed into wages and broader prices - it will act with "decisive and timely increases." This is not a benign hold. It is a hold with a warning attached.

The inflation layer most analysis skips

The standard yield comparison - net rental yield vs. mortgage rate - treats both numbers as if they exist in a vacuum. They don't, and right now the gap between them is misleading in both directions.

If CPI hits 4.2% in Q2 2026 as the RBNZ forecasts, your real mortgage rate is not 5.4%. It is closer to 1.2%. Your debt is being eroded in real terms at roughly the rate of inflation. On a $595K mortgage, that is around $25K a year in purchasing power that effectively disappears from what you owe - without you making a single extra repayment.

At the same time, your property's nominal value tends to move with inflation over time. Your rental income tends to rise with wages, which track the general price level. A $650 weekly rent in a 4% inflation environment becomes $676 at your next annual review, then $703 the following year. Term deposits earning 4.5% nominal are delivering about 0.3% in real terms before tax - which is close to nothing.

The comparison between a 3% net rental yield (plus nominal capital gain, plus real debt erosion) and a near-zero real return on cash looks considerably less one-sided than the headline yield numbers suggest.

This is not a new dynamic. It is the same one that played out in 2022 when Russia's invasion of Ukraine drove the previous oil and food price shock. The RBNZ explicitly draws that parallel in its April statement, while noting the key difference: in 2022 demand was running hot. This time, demand is weak. The supply-side inflation is arriving into an economy that is already soft - rising prices and falling real incomes at the same time. That is a difficult environment for property investors (higher costs, tenants under more financial pressure), but it is a worse environment for cash savers.

The political risk picture

New Zealand's next general election is due in late 2026. The current National-led coalition has faced persistent pressure - coalition tensions, cost-of-living sentiment, and approval polling that has softened considerably from the 2023 highs. Labour is more competitive than it was eighteen months ago, and the coalition's working majority has always been fragile.

This matters directly for property investors. Labour has historically supported a capital gains tax on investment property, and the Green Party has consistently pushed it as part of any coalition negotiation. The policy did not proceed after 2017 or 2020, but the political environment has shifted. A change of government after the 2026 election would bring CGT back onto the table with more credibility than it has had in a decade. Regardless of who wins, the current geopolitical and fiscal environment is generating spending pressures on governments across the board. Revenue options tend to expand in those conditions.

A CGT would not make property worthless - it applies to the gain, not the asset, and new policy typically includes transition arrangements. But it would reduce net returns from sale, change the decision calculus for holding vs. selling, and affect the buyer pool. Properties that are marginal investments today would become more marginal.

The broader fiscal pressure is harder to quantify. New Zealand's government bond debt is above $170 billion and rising. Governments under sustained fiscal strain tend to reach for liquid financial assets first: wealth taxes, financial transactions levies, inflation that erodes fixed-rate savings. Physical property is harder to reach. It is embedded in several hundred years of English property law tradition. Changes to that regime are slow, loud, and politically costly in ways that adjustments to savings tax treatment are not.

This is not a paranoid observation - it is a historical one. Anyone whose family held assets through mid-20th century Central or Eastern Europe has a visceral understanding of the difference between a balance in someone else's ledger and a building you can stand in. That history is extreme. But the milder version - governments finding administrative ways to reach financial assets more easily than physical ones - is ordinary and ongoing.

Not all properties are the same problem

The question is never really "should property investors sell?" It is "should this particular property be held - and is it the right configuration?"

The properties under real pressure right now are the large ones: 4 and 5-bedroom houses in suburban areas. Household sizes have been shrinking for years. These properties are expensive to maintain, hardest to upgrade to Healthy Homes standards, and increasingly hard to fill at rents that justify the capital. They are also the most exposed when a tenancy ends - a month of vacancy on a large property costs more in absolute terms than on anything smaller.

3-bedroom suburban properties are a different story. Demand is solid. Families with children, couples sharing with a flatmate, multi-generational households - the 3-bed remains the backbone of the rental market in most NZ cities. The problem is not usually demand; it is capital efficiency.

This is where the maths become interesting. In Auckland, a 3-bedroom property in a mid-ring suburb might be priced around $900-1,000K. Market rent is roughly $700-750 a week. For roughly the same capital outlay, you can often buy two 1-bedroom apartments - in the CBD fringe, or in a suburban block - and rent each at around $400-420 a week. Combined income: $800-840 a week. You have matched or exceeded the 3-bedroom's income, spread the vacancy risk across two tenants, and typically ended up with lower per-property compliance costs.

My current 3-bedroom returns $800 a week, but that is above market - the comparable rent is closer to $700-750. When the tenancy eventually turns over, that gap reprices. Two 1-bedrooms at $420 each would match that from day one, and the downside scenario (one vacancy) still leaves half the income flowing.

Regional properties - Whanganui, Invercargill, parts of Hawke's Bay - offer gross yields of 6-7% that absorb the compliance drag and still leave room. The discount to Auckland prices is real. So is the liquidity risk if you need to sell into a thin market quickly.

Why the market isn't fixing itself

There is a structural problem underneath all this that rarely gets discussed clearly: the incentives of property developers, investors, and first-home buyers are almost completely misaligned, and no one in the system is correcting it.

Developers face a simple constraint: a given section of land has a fixed cost. To maximise return on that land cost, they build the largest house they can fit on the site. A 4 or 5-bedroom house on a narrow section generates more revenue than a 3-bedroom with a yard. So that is what gets built. New subdivisions across Auckland, Hamilton, and Christchurch are full of large, relatively cramped houses on small sections, sold at prices that reflect both the land cost and the build cost of something large.

Investors look at these properties and largely pass. The rent premium over a traditional 3-bedroom house with a yard is marginal - maybe $50-100 a week more - but the capital cost is significantly higher. The yield is worse, not better. So investors don't buy them in volume.

There was a brief exception. When Labour removed interest deductibility for existing investment properties in 2021, they preserved it for new builds - a deliberate policy to redirect investor demand toward new stock. It worked, partially. Some investors bought new-build townhouses and large subdivision houses specifically for the tax treatment. Then National restored interest deductibility for all investment properties, phased through 2024-25. The incentive that had made new builds attractive to investors disappeared.

What remained was a stock of large, expensive, cramped townhouses and new-build houses that investors had bought for tax reasons, not yield reasons. Now they cannot sell them - first-home buyers cannot afford them either, and the numbers don't stack up for yield-focused investors at current mortgage rates. Developers and investors who cannot find a buyer are renting these properties cheaply while they wait for a sale opportunity. This is a significant contributor to the 12-year listing high: it is not purely organic oversupply, it is stranded policy-driven stock looking for an exit.

The stock that first-home buyers can actually afford and want - 2 and 3-bedroom older houses in established suburbs, with a yard, at a reasonable price - remains absorbed into rental portfolios, because that is where the yield makes sense for investors. The policy intervention created demand in exactly the wrong place and left the underlying problem intact.

The new-build investors who jumped at the Labour incentive are now in the worst position of anyone. They paid elevated prices for properties with marginal yield, on the assumption that the tax treatment would persist. It didn't. They are now holding expensive stock with thin rents, while the long-term investors who ignored the whole policy dance entirely - typically cash buyers or owners with low or no remaining mortgage - are sitting largely unaffected. Rising rates, interest deductibility changes, OCR moves: none of that materially touches an investor whose debt is paid down. The interest rate environment that is squeezing recent buyers is background noise to someone who bought in 2005 and has been collecting rent for twenty years.

For investors willing to move up the complexity curve, 1-bedroom apartments offer a cleaner proposition. For roughly the same total capital as one 3-bedroom house, you can often buy two 1-bedroom apartments, collect more combined rent, and serve a tenant cohort - single people, young couples - that is structurally undersupplied and growing. The compliance costs per property are typically lower, and you are not competing directly with first-home buyers for the same stock.

Where this leaves me

I am not selling the 3-bedroom yet. But I am thinking harder about its configuration than its existence. The real question is not "hold or sell" but "is this the best use of this capital?"

The exit impulse is rational. The yield is thin at market rent, compliance costs are rising, and the political environment over the next two years is uncertain in ways that affect property returns specifically.

The case for holding is also rational - particularly in an environment where inflation is forecast to hit 4.2% by mid-year. At that rate, a 5.4% fixed mortgage has a real cost of about 1.2%. Selling into a 12-year supply high and redeploying into cash earning near-zero real returns is not obviously better.

I self-manage all my properties, which recovers around $3,500-$4,000 a year per property that would otherwise go to a property manager. On a property returning $700/week, management fees typically run 8-10% of rent. That is money that stays with me if the administration is kept in order - which matters more when margins are tight.

The honest answer is that the macro forces making property uncomfortable to hold right now - rising compliance costs, thin margins, political uncertainty - are mostly the same forces making the alternatives look fragile. There is no clean exit into safety. There is only a different set of risks.
