Vacant housing: without a financing solution, renovation will remain a pipe dream.

Yes, landlords need technical support. Yes, programs like Bail Rénov' are a step in the right direction. But believing that education and administrative engineering alone will be enough to massively bring these properties back onto the market is an illusion.

The real obstacle lies elsewhere. It is financial.

Each vacant property presents its owner with a complex budgetary equation.

Renovating an energy-inefficient home is not a simple matter of painting or replacing a boiler. It often involves undertaking 25.000, 35.000, or sometimes even 50.000 euros worth of work.

Even with government assistance, the remaining cost can be substantial. For a small landlord, often retired, sometimes the heir to an older property, the amount invested represents a significant portion of their savings (if they have any savings left). Added to this financial burden are a period without rental income, due to the prohibition on renting until the renovations are complete, the uncertainty linked to constantly evolving regulations, and the fear of new obligations in the years to come.

Faced with this accumulation of risks, some prefer to wait. Others sell. Some leave the property vacant.

It's not the environment they're rejecting. It's the financial risk they can't absorb.

One blind spot remains in this debate: solvency. Owners are being asked to invest heavily to keep their properties on the market. But little is being said about their actual ability to finance these renovations.

Without a structured financing solution: collective loan in co-ownership, spreading of monthly payments, restructuring of existing debts and credit buyback, renovation remains a distant theoretical project.

In a condominium, nothing is ever purely technical. You have to convince the majority, reconcile widely varying financial situations, and accept that some co-owners may not be able to participate. General meetings then become a stage for exposing financial vulnerabilities. Without a structured financing solution, the project stalls. Technical support provides reassurance. Financing unlocks the potential.

In a constantly evolving regulatory environment, it is necessary to secure the process. For several years, the framework has been changing rapidly: progressive bans, "readjustments" to the calculation method, adjustments to subsidies, new requirements… This legislative "movement" fuels a wait-and-see attitude, and above all, mistrust on the part of property owners.

This is precisely why a comprehensive approach is essential. Centralizing auditing, grant applications, financial structuring, energy optimization, and operational monitoring within a single process secures the investment and provides the homeowner with greater visibility. Energy renovation is not just a climate issue; it's a choice that can permanently alter a household's financial trajectory.

We will only bring housing back onto the market by restoring landlords' confidence. Vacancy cannot be combated solely through regulations. The solution lies in making renovation affordable, transparent, and sustainable.

If we truly want to bring housing back onto the rental market, we must address the problem in all its dimensions: technical, regulatory… and above all, financial. Without this, the objective is laudable, but it will remain theoretical.
