I think it is a really lovely house, generous room sizes, obviously needs much renovation, but could make a wonderful family home.
Pretty similar to what we had the move before last, very large detached family home, replaced kitchen/utility, replaced all three bathrooms, recarpeted/decorated throughout. And made it look great, sold it this year, as needed a bungalow due to my disability, sold for over double what we paid for it nearly 18 years ago.
If you can afford to do the work, I would go for it, just bear in mind that trades are difficult to get hold of at the moment and the cost of building materials have risen sharply.
Good luck with whatever you decide.
