This is me living in the land of the glass half full but:
Once it is proven that FD did this and he is locked away for the rest of his useless life, and it was 100% guaranteed that he cannot benefit from the sale of any of those homes...
I would love it if some of grandma’s rich friends bought these houses so that the grandma can be paid back and so that the kids will have what they need later on.
It makes me sad to think that some of their inheritance from their grandparents (when grandma dies hopefully no time in the next 20 years!) was squandered by their greedy dad, and now those properties will be foreclosed and sold at auction for cents on the dollar and the kids won’t get anything from it.
I mean, maybe grandma is so loaded that the debt on these homes is but a drop in the bucket but still.
It might be better for the children for her to specifically bequeath funds to them outside of Fore Group and completely bypass any chance FD's relatives have to lay claim on foreclosed properties.
If FD goes to prison (if, HA!) then Fore Group will have to file for bankruptcy and the properties will be sold for whatever.
I would prefer nothing do to with FD deals with the children he so horribly wronged
