There are many other items, listed in the schedule of finishes for an off-the-plan apartment, that need careful studying.
Generally, if an apartment is listed as investor quality, this means it is of lower quality. Some buildings have apartments with different quality -- for example, a lower floor apartment may have lesser finishes than an apartment on a higher floor. In the Flow development, the apartments on one side of the building (the river side) have a higher quality finish than the apartments on the other side of the building (the city side). So take care!
