She has lost confidence in the standard of build. It does not feel like a new house anymore with all that has had to be done to put things right. She has asked the developers for an independent inspection to document the problems but this has been ignored. She would quite happily get her money back and move out.
They will "put it right" so to speak at no cost but that is not her worry. If all this is happening to a new build i.e. dampness etc. there is something far wrong. She is the first occupant of twelve new houses in the development. She has no confidence that worse problems may develop and she can't sell the house in the future. She has put her life savins g into this new property and it is turning out to be somewhat of a lemon.
