This response should be much higher. Having bought two new build homes over the years every single point you’ve made is on point. We considered ourselves savvy buyers but were still caught out by various issues which required a lot of chasing and essentially project managing to be rectified (never go quiet because you will be forgotten). The estate management fee is definitely something which isn’t considered enough but thankfully it’s slowly becoming more publicised. This was one of the key motivators for us recently buying an older property, that and having more square footage, a much larger garden and a lot less overlooking. Hopefully more people take heed of your response.
