The PTZ is a household support scheme created in 1995 for a means-tested purchase of a main residence. Its interest rate at 0% allows beneficiaries to repay only the borrowed capital.

It is proposed by the bank when designing the financing plan for a real estate purchase. The PTZ cannot finance the entire purchase, but only a portion, the maximum of which is now set at 40%. Conventional bank financing can complement the rest of the loan.

The PTZ can be applied to partially finance a purchase of housing:

  • new or to be constructed;
  • old (completed more than 5 years ago, including renovations or energy-saving work);
  • social.

PTZ: Can you ask?

The PTZ is for individuals who did not own their primary residence during the 2 years prior to loan application (not required for some profiles).

Obtaining the loan depends on several conditions : the level of resources, the geographical location of the dwelling purchased, the type of project or the composition of the household; your income must not exceed a certain ceiling which varies according to the geographical area of the future dwelling. offers you a simulator to use if you apply for PTZ by the end of 2023: Is PTZ possible in your municipality?

By indicating only the municipality in which the dwelling to be acquired is located, you can know:

  • in which area (A, Abis, B1, B2 or C) the municipality is located;
  • the type of PTZ you can request.
