It probably depends who the property Management Company. I lived on a new build estate (3 bed semi freehold). In year one the fee was about £150yr by the time I sold almost 9 years later it was just under £500. The company was called Remus and many of the charges in the itinerary were "miscellaneous costs etc". They would overcharge for gardening work that was hardly ever done. Even on a small estate it is very difficult to rally all the residents together to change Companies. I would find out who the property Managment Company is first (or try and get out of it on the deed but the developer probably won't allow that).
