I didn’t know about this. I just read an article here [Rachats ultérieurs dans le 3e pilier dès le 1er janvier 2025 | Allnews](https://www.allnews.ch/content/r%C3%A9glementation/rachats-ult%C3%A9rieurs-dans-le-3e-pilier-d%C3%A8s-le-1er-janvier-2025) which says that this is possible! I wonder if this is possible to buy back what you used for a house purchase as well?
