Three co-owners on a landing, a renovation voted in the general assembly, and a call for funds that comes at the wrong time. The collective mortgage allows the homeowners’ association to take out a single loan to finance common work, without each owner having to approach their bank individually. The mechanism has existed for several years, but its governance constraints and practical limits remain poorly understood.
Vote in the general assembly: the constraint that blocks collective projects
It is often assumed that the collective loan is decided by a simple majority, like a classic renovation. The reality is more rigid. When the homeowners’ association borrows in its own name, the vote requires the unanimity of the co-owners. A single opponent is enough to derail the arrangement.

Two other formulas exist to bypass this lock. The loan can be taken out for the benefit of only willing co-owners, or for those who have not expressly refused to participate. In the second case, each co-owner has a period of two months after the vote in the general assembly to notify their refusal to the property manager.
In practice, it is observed that the “opt-out” formula (participation unless explicitly refused) is the most common for energy renovation work. It prevents the project from being blocked while leaving an exit door for those who prefer to finance their share differently. Adopting a collective mortgage solution in this mode facilitates the management of dissent without paralyzing the co-ownership.

Collective loan for co-ownership and energy renovation: what has changed recently
The collective loan is not only used to repaint a stairwell. Its use has expanded to energy performance projects, including less conventional arrangements such as the installation of solar panels for collective self-consumption or the resale of photovoltaic production.
However, the financial equation of these projects has recently evolved. The photovoltaic self-consumption bonus was abolished in June 2026, which alters the financing plan for co-ownerships that were considering coupling a collective loan with this aid. Co-owners who were counting on this bonus to reduce their remaining costs must recalculate the project’s profitability before voting.
The zero-interest eco-loan remains accessible for energy renovation work voted in the general assembly. The property manager takes it out on behalf of the association, and only the participating co-owners repay their share. This system remains of great interest for thermal insulation or the replacement of collective boilers.
Types of work fundable by collective loan
- Work on common areas: renovation, roofing, bringing networks up to standard, refurbishment of lobbies and circulation areas
- Collective interest work on private areas: installation of individual meters, replacement of windows as part of a comprehensive renovation program
- Energy projects: external insulation, changing the collective heating system, photovoltaic installation on the roof with self-consumption or resale
Repayment management: who pays what when a co-owner sells
The point that most articles gloss over is what happens during a sale. The debt related to the collective loan is attached to the unit, not to the person. When a co-owner sells their property, the buyer takes over the remaining repayment obligation, unless the seller settles their share before the transaction.
The property manager must provide a dated statement that mentions the remaining amount due for the collective loan. The notary includes this information in the sales deed. In practice, responses vary on this point: some property managers delay in producing the dated statement, which can delay the signing.
Points of caution for the property manager and co-owners
The property manager plays a central role in managing the loan. They negotiate the terms with the bank, call for payments from each participating co-owner, and monitor unpaid dues. An unresponsive property manager can jeopardize the smooth running of the loan, especially if late reminders lead to bank penalties passed on to all borrowers.
- Check that the property management contract explicitly provides for the management of a collective loan (some contracts charge extra for this service)
- Request in the general assembly that the property manager presents at least two comparative bank offers before the vote
- Ensure that the co-ownership regulations do not prohibit taking out loans in the name of the association (rare but existing in older co-ownerships)
- Require the mention of the collective loan in each dated statement provided during a transfer
Collective real estate financing: when the loan is not the right option
The collective loan is not always the most suitable choice. For work of a moderate amount, the mandatory work fund (fed by the annual contributions of co-owners) may be sufficient. Resorting to a loan for a small project generates processing fees and interest that increase the overall bill without real necessity.
Another situation where the collective loan may pose a problem is a co-ownership with a high rate of unpaid dues. The bank analyzes the financial health of the association before granting the loan. A poorly maintained maintenance log, recurring unpaid charges, or an insufficient work fund can lead to a refusal or unfavorable rate conditions.
Each co-owner also retains the option to take out a personal loan to finance their share. This option offers more flexibility on the repayment term, but it deprives the co-ownership of the leverage effect of group negotiation with the bank. The choice between individual and collective financing depends on the amount of work, the size of the co-ownership, and the property manager’s ability to manage the file.
