For investors with substantial capital, the question is rarely whether Monaco or the French Riviera is attractive.
Both are.
The more interesting question is what €10 million actually buys you in each market — and what the investor is giving up in exchange.
Monaco offers scarcity, international demand and a unique tax environment. The French Riviera offers scale, land, operating assets and a much broader investment universe.
The distinction matters.
Monaco Is a Scarcity Market
Monaco is fundamentally different from most European real estate markets.
There is very little land. New supply is limited. Demand is international and the market attracts a concentration of high-net-worth individuals, family offices and international businesses.
This creates a particular investment characteristic: scarcity itself becomes part of the asset.
A €10 million investment in Monaco is therefore likely to be concentrated in a relatively small number of high-value residential assets.
The investor is paying for location, scarcity and access.
That can make sense for a principal residence, a long-term store of wealth or an asset intended to be held across generations.
But it does not necessarily make Monaco the better investment simply because the underlying property is more expensive.
The French Riviera Is a Different Investment Proposition
Move a short distance west or east from Monaco and the investment universe changes dramatically.
The French Riviera includes markets such as Roquebrune-Cap-Martin, Menton, Cap d’Ail, Nice, Villefranche-sur-Mer, Beaulieu-sur-Mer, Cannes, Antibes and Saint-Jean-Cap-Ferrat.
The range of available assets is substantially broader.
An investor can acquire villas, apartment buildings, development land, hotels, commercial property, redevelopment opportunities and income-producing assets.
The investment is therefore no longer simply about owning a scarce residential property.
It becomes a question of **asset selection and capital allocation.**
€10 Million Is Not the Same Investment
Consider two investors, each with €10 million.
The first places the entire amount into a single Monaco residential property.
The second uses the same capital across several French Riviera assets.
The second investor may be able to create a portfolio containing residential property, an operating asset and a development or value-add opportunity.
The return profile can therefore be very different.
The Monaco investor may have greater scarcity value and potentially stronger defensive characteristics.
The French Riviera investor may have greater diversification and more opportunities to create value through acquisition, development, refurbishment or active management.
Neither is automatically superior.
They are different investments.
Tax Changes the Calculation
This is where the issue discussed in my previous article becomes important.
For a Monaco-based investor, owning French real estate can bring French tax considerations that do not arise in the same way from owning property in Monaco.
France’s Impôt sur la Fortune Immobilière (IFI) applies to taxable real estate wealth above the relevant threshold, with progressive marginal rates reaching 1.50% for the portion above €10 million. The calculation can also involve property held indirectly through companies and investment structures.
That does not mean that French real estate is unattractive.
It means that the tax cost has to be incorporated into the investment model.
A property generating a strong rental or development return may justify the additional tax.
A low-yielding trophy property may not.
The relevant question is therefore not simply the purchase price.
It is the after-tax return on capital.
The €10 Million Question
At €10 million, portfolio construction becomes increasingly important.
An investor does not necessarily need to choose between Monaco and France.
The more sophisticated solution may be to use both.
Monaco can provide the base.
The French Riviera can provide the investment universe.
A Monaco residence can serve a personal or wealth-preservation function while French assets are acquired for income, development or capital appreciation.
This is particularly relevant where the investor’s objective is not simply to own property, but to build a diversified portfolio around the Riviera.
Residential Wealth vs. Investment Capital
There is also an important distinction between wealth storage and investment capital.
A €10 million apartment in Monaco may be an excellent store of wealth.
But it may not produce the same return on capital as a €10 million portfolio of assets where the investor can actively improve the underlying properties.
Development, refurbishment, repositioning and operational improvements can create returns that are not available from a fully priced trophy apartment.
This is the fundamental difference between buying an asset and investing in an asset.
Scarcity Has a Price
Monaco’s scarcity is one of its greatest strengths.
It is also one of its costs.
The investor pays a substantial premium for the right to own an extremely scarce piece of real estate in one of the world’s most concentrated wealth markets.
That premium may be entirely justified.
But an investor should not confuse scarcity value with investment return.
They are related, but they are not the same thing.
Where Would I Put the Next €10 Million?
There is no universal answer.
If the objective is a principal residence, wealth preservation and long-term ownership, Monaco can be difficult to replicate.
If the objective is investment return, diversification and active value creation, the French Riviera presents a considerably broader opportunity set.
And if the objective is both, the answer may be a combination of the two.
The important point is that the decision should not be made by comparing property prices alone.
It should be made by comparing:
tax + financing + yield + capital appreciation + liquidity + concentration + development potential.
That is the real investment equation.
The Riviera Should Be Viewed as One Market
Perhaps the biggest mistake is to treat Monaco and the French Riviera as completely separate investment markets.
They are geographically close and economically interconnected.
Capital moves across the border.
People move across the border.
Businesses operate across the border.
And property investors increasingly have the ability to choose where within this relatively small geographic area they want to deploy their capital.
For a €10 million investor, that creates an important opportunity.
The question is no longer:
“Monaco or France?”
It is:
“What combination of Monaco and the French Riviera produces the best risk-adjusted, after-tax return on my capital?”
That is a much more interesting question.
