In North America, we have probably seen this type of complaint in nearly every urban area with some density in skyline and an accompanying residential mix. or the dreaded, so-called 'residential ghetto'. Some of the newer developments advertise that they will 'never' have an obstructed view, based on site configuration (of course that is not in the contract that you sign).
Indeed. Advertising and pretty pictures of "things to be" in real estate sales materials mean squat. The Purchase and Sale Agreement is what holds water. My experience has been forget a real estate broker when buying an unbuilt property, it's a waste of time if you are a good negotiator and know what you want. Spend the time and money with a good lawyer prior to purchasing in order for him/her to scrutinize the P & S Agreement with you.
Given all the activity in the region I'm a little surprised some of these projects are moving ahead so quickly given the high demand for materials and skilled labour. Blu went from sales to a hole in the ground in pretty good time, about 13 months.
