Stocks vs Property: Where Should You Invest $100k?

If you’re in your late 20s or early 30s and have somehow saved your first $100,000, firstly: well done. That is genuinely hard in New Zealand right now.

The problem is that once you get there, everyone suddenly has an opinion about what you should do next.

Your parents say buy property before you’re “locked out forever”. Your investing mate owns ETFs and thinks houses are overrated. Meanwhile, half the internet is predicting some kind of economic apocalypse.

So, should you put $100,000 into stocks or property in New Zealand?

There isn’t one winner. Property gives you access to leverage and can force you to build wealth consistently, while shares are easier to diversify, easier to sell and give you far more flexibility. The better investment is the one that fits your finances and the life you actually want to live.

Why has property created so much wealth in New Zealand?

New Zealanders have a fairly unique relationship with property.

For decades, buying a house has been treated as one of the ultimate financial milestones. And to be fair, that advice worked incredibly well for many older Kiwis who bought ordinary homes and watched them turn into very valuable assets.

But there’s an important reason property produced so much wealth that often gets overlooked: Leverage.

If you invest $100,000 into shares, you own $100,000 of shares. But $100,000 might allow you to buy a $700,000 property using a mortgage.

If that property rises 10%, the asset gains $70,000 even though you only contributed a fraction of the purchase price yourself.

That ability to control a much larger asset using borrowed money has been a huge part of New Zealand's property wealth story.

What is the downside of property leverage?

Unfortunately, leverage works both ways.

It makes gains look fantastic when prices are rising, but it can also magnify losses when prices fall. Then you have the mortgage itself.

Interest rates can rise. Tenants can leave. Insurance and rates keep arriving. Something eventually breaks, and sometimes that something is your roof deciding it would like to become an indoor waterfall.

This is where property can feel very different from owning shares.

Stock prices move constantly, so their volatility is impossible to ignore. Property prices aren't flashing on an app every three seconds, which makes property feel more stable.

But not seeing the volatility doesn't mean the risk isn't there.

Are stocks less risky than property?

Not necessarily, they simply come with different risks.

A diversified ETF can spread your money across hundreds or thousands of companies, industries and countries.

A residential property might leave a huge amount of your wealth concentrated in one house, on one street, in one New Zealand city.

On the other hand, shares can fall sharply and publicly. You need to be able to watch your portfolio drop without panicking and selling at exactly the wrong moment.

Property can create different pressure through debt and cash flow. Neither is risk-free.

What are the advantages of investing in stocks?

One of the biggest advantages of stocks is something that rarely appears in investment return comparisons: Freedom.

Your ETF doesn't particularly care whether you move to Australia, take six months off, change careers or start a business. Property is harder to ignore.

A large mortgage naturally makes stable income more important because repayments continue regardless of what else is happening in your life.

Shares are also liquid, relatively easy to diversify, and you can invest gradually rather than needing a six-figure deposit before getting started.

For someone who values mobility and flexibility, that matters.

What are the advantages of investing in property?

Property has one enormous behavioural advantage: It forces you to invest.

When you have a mortgage, the repayment usually gets made before almost everything else. People restructure their spending around it.

Stocks don't force the same discipline. You can set up an automatic investment plan, but you can also cancel it next month because you suddenly decided you deserve a trip to Europe. That forced consistency is one reason property has worked so well for many people.

Property also suits people who genuinely enjoy owning something tangible, renovating, managing projects and improving an asset over time. For those personalities, it can be a great fit.

So, should you buy stocks or property with $100,000?

It really comes down to which investment can you realistically stick with for the next 20 or 30 years?

Property can create enormous wealth through leverage and consistent repayments. Stocks offer diversification, flexibility, liquidity and the ability to invest without taking on a huge amount of debt. And realistically, many New Zealanders will own both at different points in their lives.

Someone who values stability and likes owning tangible assets may prefer property. Someone who values flexibility, travel, career mobility or lower financial commitments may prefer shares.

The important part is not finding the theoretically perfect investment. It’s building a system you can actually stick with.

Because if you've already saved your first $100,000, you've probably completed one of the hardest parts.

From there, time and consistency start doing much more of the work.
