Building wealth when buying a home is out of reach

For a lot of people under 40, buying property where they live is no longer realistic. Here are the other ways to build real net worth, with their honest trade-offs.

For two generations, the path to wealth in France felt obvious. You bought your home as early as you could, paid down the loan for twenty-five years, and ended up owning a real asset. For a lot of people under 40, that path has quietly closed. Prices in the cities where the jobs are have run far ahead of salaries, and a deposit that used to take a few years now takes more than a decade.

It is easy to read that as a dead end. It is not. The goal was never the bricks. The goal was net worth, and a home is only one way to build it. Here are the others, with the parts the property-or-nothing crowd tends to skip.

Start with what you are actually trying to do

Owning your home does two things at once. It gives you somewhere to live, and it forces you to save, because the mortgage payment builds equity instead of vanishing as rent. The second part is the one people forget. Most of the wealth from buying comes not from clever timing but from being made to put money into an asset every month for decades.

You can recreate that second part without the house. The trick is to make the saving automatic and put it somewhere that grows. That is the whole game, and it does not require a notaire.

Index funds, the unglamorous workhorse

A global index fund holds thousands of companies across the world in one cheap, liquid product. You can start with a hundred euros, add to it every month, and never think about it. Over long periods it has grown wealth at a rate property in most cities cannot match, with none of the maintenance, tenants, or twenty-five year commitment.

In France you hold these inside a PEA or an assurance-vie to keep the tax low, and a PER if you want a deduction now and can lock the money until retirement. The boring version of this strategy, a global ETF bought automatically every month and left alone, has quietly made more ordinary people comfortable than any property scheme.

The honest catch is that you have to actually do it. A renter who invests the gap between rent and a mortgage can come out ahead of a buyer, but only if that gap really gets invested instead of spent. Most people who claim they would invest the difference never do. Automating the transfer on payday is what separates the two.

Paper real estate, if you want property exposure

If you specifically want exposure to property, you do not need to buy a flat to get it. SCPI in France, or REITs more broadly, let you own a slice of a large portfolio of buildings and collect a share of the rent, without a mortgage, a tenant, or a leaking roof at midnight.

Be clear-eyed about the trade-offs. Entry fees on SCPI are high, the rental income is taxed as property income at your marginal rate plus social charges, and you cannot always sell quickly. It is a real way to get property in your portfolio without a loan, but it is not free money, and the fees mean it rewards patience.

The three routes, with their real trade-off
  • Index funds in a tax wrapper

    Open from a hundred euros, liquid, no maintenance. Trade-off: the gap between rent and a mortgage payment has to be genuinely invested, which most people never do.

  • Paper real estate

    Property exposure without a loan or a tenant. Trade-off: high entry fees, rents taxed at your marginal rate plus social levies, and you cannot always sell quickly.

  • The savings rate itself

    The actual engine: a quarter of income into an ordinary vehicle beats five percent into a clever one, every time. Trade-off: nothing to buy, so nobody to tell you about it.

None is better in the abstract and nothing here says which suits you: they are three different mechanisms with three different constraints. The last line weighs most, and it is the only one you cannot buy.

The part nobody can sell you

None of these vehicles matter as much as the rate at which you feed them. Someone saving a quarter of their income into a plain index fund will outpace someone saving five percent into a clever one, every time. The vehicle is a detail. The savings rate and the number of years are the engine.

This is the good news hidden in the housing problem. You do not need to win a bidding war or qualify for a huge loan to start. You need a number that leaves your account automatically each month and a place for it to compound. You can begin this week with whatever you have.

Where IgniFI fits

The hard part of this approach is that it is invisible. A house is a thing you can see and stand in. A growing investment account is just a number that creeps up slowly, which makes it easy to neglect. Seeing your net worth in one place, watching it climb, and getting a projected date for your goals is what makes the invisible path feel real enough to stick with.

Buying a home may still happen for you later, on your terms, once you have capital behind you. In the meantime, the worst move is to treat wealth as something that only starts the day you get the keys. It starts the day you put the first hundred euros to work.
