We live in the downstairs flat of a Victorian house and the freehold is held by our council. This has always worked fine before as they do the work pretty well. Our upstairs neighbour wants to buy the freehold as they want to extend into the roof and have had bad experiences getting the council to fix a fault in their wall. I feel a bit uneasy about this because a) the existing arrangement suits us and b) because if they can't get a repair done through the council I worry how they will project manage a roof conversion. I am also worried that a roof conversion will mean scaffolding in our garden and all kind of mess and noise. We are hoping to move soon so not sure if share of freehold would be a selling point or not? They are willing to pay the legal fees for the freehold. They are a nice couple but quite ineffectual and a bit on another planet. What would you do?
