Tax break Scheme for first time buyers in France?

I was told by an English neighbour that in my block that when they bought their flat there was a first time buyer scheme for french properties from the french government where up to the first 40,000 euros was tax free. She said I should check in case it’s still in existence as maybe I could also benefit from it. Does anyone know what it could be?

This may be of use:

Thank you Veronique. I had a look but could not see the tax break there of 40,000 euros. I guess it must exist though as a mortgage broker recently came back to be with a rate of 0% on the first 30,000 euros of the loan.
