Why Diederik van Maren Believes Dutch Investors Should Diversify

Dutch property prices keep climbing while opportunities elsewhere sit overlooked. Diederik van Maren has spent years arguing that staying local is the real risk.

Most Dutch investors default to what's familiar: an apartment in Amsterdam, a rental in Rotterdam, maybe a holiday home in Zeeland. It feels safe. It isn't.

Concentration in one market, one currency, and one regulatory system creates exposure that many investors don't notice until something changes—a tax law, an interest rate hike, a housing policy shift.

This article explores why diversification abroad makes sense right now, what's driving the shift, and how a more global mindset can protect and grow a property portfolio over time.

The Hidden Cost of Staying Local

Every investment carries risk, but concentrated risk is quieter and more dangerous. When 100% of a portfolio sits in Dutch real estate, every policy change hits at once.

Recent tax reforms around box 3 wealth taxation have already reshaped returns for thousands of property owners. Investors who diversified earlier felt less of that shock.

Think about it this way: a farmer who plants only one crop loses everything in a bad season. One who plants several crops across different fields survives it. Real estate works the same way.

Diversifying across countries doesn't just spread risk—it opens access to markets with different growth cycles, different demand drivers, and often, better yields than an oversaturated domestic market can offer.

What's Driving Dutch Investors to Look Abroad

A few forces are converging at once, and none of them show signs of slowing down.

• Domestic price pressure: Dutch housing remains among the most expensive in Europe relative to income.

• Regulatory tightening: Rental caps and stricter buy-to-let rules have reduced margins for landlords.

• Currency and lifestyle appeal: Markets like Spain and the Caribbean offer both financial upside and personal enjoyment.

  
  

For example, a Dutch investor buying a coastal apartment in Spain today can often achieve stronger gross rental yields than a comparable property in Utrecht, while also gaining a place to vacation.

That combination—income plus lifestyle—is hard to replicate with a purely domestic strategy.

Diederik van Maren's Case for Global Thinking

Few people make this argument as convincingly as Diederik van Maren. His own path—from Marbella's coastline to Curaçao's Caribbean market—wasn't theoretical. It was lived experience, market by market.

That firsthand exposure shapes his core belief: real diversification isn't just financial. It's cultural and geographic too. Understanding how buyers think in Spain versus how they think in the Dutch Caribbean requires more than data. It requires time on the ground.

Applying Global Lessons at Home

Interestingly, this same philosophy shows up in Van Maren's Dutch projects too. His latest development in Meppel—17 contemporary homes—reflects lessons drawn from international markets: prioritize design, understand local buyer psychology, and never assume one formula works everywhere.

That cross-pollination of ideas, moving between international and domestic projects, is exactly what diversification is meant to produce.

How to Diversify Abroad Without Overexposing Yourself

Diversification only works if it's done carefully. Rushing into a foreign market without preparation can create new risks instead of reducing old ones.

A structured approach helps:

1. Start with one secondary market rather than spreading too thin immediately.

2. Understand local tax treaties to avoid double taxation on rental income.

3. Budget for currency fluctuations, not just purchase price.

4. Partner with advisors who know both Dutch and local regulations.

5. Visit the market before committing—photos and listings rarely tell the full story.

   
   

Skipping these steps is how diversification turns into overexposure instead of protection.

Common Questions About International Diversification

Does diversifying abroad mean giving up Dutch investments entirely? Not at all. Most successful investors keep a Dutch base while adding one or two international markets for balance.

Is Spain still a smart choice for Dutch investors in 2026? Spain continues to attract Dutch buyers thanks to stable demand, favorable pricing compared to major Dutch cities, and strong tourism-driven rental potential.

How much of a portfolio should go into foreign property? There's no universal number, but many advisors suggest starting with 10-20% exposure before scaling further based on results.

Final Thoughts

Diversifying beyond Dutch borders isn't about abandoning what's familiar—it's about reducing risk while unlocking growth that a single market can't provide. Key takeaways worth remembering:

• Concentrated portfolios carry hidden regulatory and tax risk

• Markets like Spain and Curaçao offer both yield and lifestyle value

• Lived, on-the-ground experience beats spreadsheets alone

• Diversification should be gradual, not rushed

  
  

Diederik van Maren's own journey—and his latest Meppel development—prove that global thinking and local execution aren't opposites. They're proven partners. The real question is: how long can Dutch investors afford to wait before diversifying their own portfolios?
