Financing a property project: the complete picture

📐 Article4 min read

Financing a property project is not simply a bank loan. A wide range of solutions exists, often combinable, and the choice depends on the operator's profile, the type of project, its value and its risk. Identifying the right levers at feasibility can make the difference between a project that happens and one that stays on paper.

What you will learn

  • The families of property finance and how they work
  • Financing for individuals against financing for professionals
  • The solutions for development, buy-to-let and public facilities
  • How to combine several sources of finance

Financing for individuals

The classic mortgage

This is the dominant route for individuals building a house or buying off plan. It is granted by retail banks on the basis of repayment capacity, a maximum debt service of 35 % of net income under the national recommendations, generally over 15 to 25 years.

Minimum deposit 10 to 20 %, covering at least the legal fees
Rate 3.10 % on average in May 2026 on new housing loans excluding renegotiations, according to the central bank, after a peak of 3.59 % in January 2024. The rate actually obtained varies with the term and the borrower's profile.
Security A charge on the property or a bank guarantee
Term 15 to 25 years, up to 30 in some cases

Assisted loans

The zero-interest loan An interest-free loan for first-time buyers subject to income conditions. Since offers issued from 1 April 2025 it covers every new dwelling across the whole country.
The social access loan A regulated loan for modest households, giving entitlement to housing benefit on purchase. State guaranteed.
Shared-equity tenure Land and building are separated: the buyer acquires the building and leases the land from a land trust. The cost falls by 30 to 40 %.

Financing for professionals

The development loan

Short-term finance, 12–36 months, granted to operators to fund the delivery of a development. Funds are drawn progressively and repaid from off-plan sales. Typical conditions: 40–50 % pre-sales, 10–20 % equity, a completion guarantee mandatory.

Corporate finance

For large property companies and institutions: bond issues, capital increases, property debt funds. These instruments give access to substantial volumes on terms potentially better than bank credit.

Club deals and co-investment

For operations of 5 to 50 M€, co-investment structures, family offices, institutions, foundations, allow projects beyond a single operator's capacity to be funded, sharing the risks.

Financing public facilities

State deposit institution loans Long-term loans, 20–40 years, at subsidised rates for authorities and social landlords, funded from regulated savings.
State equipment grants Central grants to local authorities. The subsidy rate varies from 20 to 50 % according to the project.
European regional development funds Co-financing up to 50 % for eligible projects, managed by the regions.
Public-private partnership Entrusts finance, construction and maintenance to a private operator in exchange for a charge over 20–30 years.

Combining sources

The great majority of projects combine several sources. Optimisation means maximising the share of the cheapest capital, grants, subsidised loans, and minimising the share of the dearest.

An example, a typical social housing operation: 15 % landlord equity · 45 % subsidised state loan · 20 % local authority grant · 10 % central grant · VAT at 5.5 %, an implicit subsidy. That combination makes the operation viable despite rents capped below the open market.
