Hi we are about a week from exchanging on a house with 5 acres. We have found out the land has mineral/mining rights, there is an old gravel pit next door that is now a lake/ private house. The rights were not in the property details and the agent didn’t mention them. Does this reduce the reduce the value of the property? I have not overly concerned about the rights and we will take out an indemnity, just whether the house been valued to high. As I said the agent said they didn’t know.
