Has anyone replaced poly b piping in their home?

Hi! I am hoping to hear about other's experiences with replacing poly b piping in their home and how their process was in obtaining permits, time it took, costs and if they have any plumbing company recommendations for this type of work.

I am currently in the process of buying a home and it turns out they have poly b piping (ground floor is radiant floor heating and upper floor is water baseboard heating). I am trying to decide whether to walk away from this home, or just throw money at it to replace all the plumbing 🥲
