The French intergenerational pact rests on a simple principle: workers contribute, pensioners receive. As long as workers are numerous relative to pensioners, the system holds. When the ratio reverses, the machine stalls. That is exactly what is happening, and it is only the beginning.
1. Demographics are working against you
The ratio of workers to pensioners is the most decisive figure for the solvency of the system. It has collapsed in 60 years and will keep falling. This projection is not an opinion, it is a statistical certainty: the people who will retire in 2050 have already been born.

Three levers exist to keep the system going: raising contributions, pushing back the retirement age, or lowering pensions. All three are under way simultaneously. None will be enough.
2. The replacement rate is falling generation after generation
The replacement rate is the percentage of your final net salary that you actually receive in retirement. For the generation born in 1950, it was close to 75%. For those retiring in 2030, it will be around 60%. For the generation born in 1990, who will retire around 2055, the figure is 50% at best.

3. Buy-to-let property: the most powerful lever
Building retirement capital through life insurance (assurance-vie) or a PEA (French share savings plan) is a good thing. Doing it through leveraged buy-to-let property multiplies the effect by 3 to 5 thanks to bank leverage. You buy a €200,000 property by borrowing 90%: it is the tenant's rent that repays the loan. At the end of the loan, the property is entirely yours, and continues to produce a monthly income indexed to inflation.

Value of a property portfolio over 25 years (€200,000 invested with a loan)
Assumptions: €20k deposit, €180k loan over 25 years at 3.5%, property appreciation of +2% a year, rents reinvested. Compared with an equivalent investment in a Livret A savings account.
Over 25 years, the same initial financial effort (a €20,000 deposit) generates wealth 8 times greater in property than in a liquid investment. That is leverage: it exists nowhere else.

4. When should you start?
Time is the most powerful multiplier in investment. The earlier you start, the lower the monthly effort needed to reach a comfortable retirement. And the longer you wait, the more out of reach the entry ticket becomes.

5. The Covesta method
We do not sell a product; we support you over the long term. Our conviction: a successful investment rests on the quality of the sourcing, the rigour of the works, and delegated property management to protect your time. Three levers that make the difference between an investment that builds wealth and one that consumes it.
- Off-market sourcing: we gain access to properties before they are listed, at an average discount of 8 to 15% to the market.
- Managed energy renovation: DPE ratings (French energy performance certificate) of F/G turned into C or B, immediate value uplift + compliance with the 2025 regulations.
- Property management at 6% excl. VAT: all inclusive, with co-ownership charges, claims and unpaid rent handled at no extra cost.
- Transparent fees: 5 to 7.5% excl. VAT depending on the value of the property, published openly.
“Buy-to-let property is the only investment where the bank agrees to finance 80 to 100% of the investment for you. It is this singularity that makes it the retirement tool par excellence.”
