Tailored Mortgage Support for Large Families
The Walloon Housing Fund grants social loans to large families under conditions adapted to each situation. These loans are intended to make home ownership and quality housing more accessible while maintaining a sustainable household budget.
Created in 1929, the Fund’s missions include social mortgage loans, ecopacks, renopacks, rent assistance, and the management of social housing organizations (OFS). Our role as brokers is to help you understand these mechanisms and find the solution that truly matches your needs in 2026.
What Can a Large Family Mortgage Loan Finance?
The large family mortgage loan from the Walloon Housing Fund covers a wide range of real estate projects. It is not limited to the purchase of a classical residential property: it can also be used for renovation, transformation, or energy improvements, always with the aim of enhancing the comfort and sustainability of your family home.
This type of social loan is particularly suitable for large families who want to better organize their living space, make it more energy efficient, or prepare a home able to welcome multiple generations under the same roof. The conditions are calculated to keep your monthly payments aligned with your income and the number of dependent children.
Large family mortgage loans may be granted for:
- the purchase, construction, renovation, or transformation of a home;
- the implementation of energy-saving works to reduce consumption and bills;
- the repayment of an expensive loan already contracted for a home, via a refinancing operation under better conditions;
- the creation of nearby housing intended to accommodate elderly parent(s) or other family members;
- the purchase of a building plot to prepare a future construction project.
By combining social mortgage loans with ecopacks and renopacks, Walloon families can finance both the acquisition and the renovation of their home while improving its energy performance. Rent assistance may also be available when the renovated housing is mainly intended for large families.
