Unfortunately I don’t know anything about inheritance laws, i.e. whether the property is at some point owned by you personally, as opposed to in your capacity as executor / administrator of the estate.
From a VAT perspective, an option to tax applies to all supplies by the person who made it – and that extends to an executor / administrator after that person’s death, because you’re effectively seen to be running their “business”. However, if the property is now owned by you personally, you will not be affected by any option to tax which may have been made by your father.
