I am in attorney review for a home with a pool. Love the home, but after prying for an inspection of the pool I was informed it was constructed in the 70s with wooden walls. This now seems like a bad investment. Should I be concerned about it? It has apparently had vinyl lining replaced in the last 5-8 years but I'm worried about the underlying structure as I'm not the most familiar with pool care. Any help would be much appreciated.
