Just caught up on Sundays episode. Surely Mark will have formed a limited company, to buy / manage the hotels. This means that his personal assets can't be touched by the debts of the buiness - so how has he (personally) managed to go bankrupt?
Presumably he injected cash into the company that was his personal savings or he took out loans to get cash to inject in, that were secured on his personal property/assets. So when the company went down he will have lost what he put in.
