Does anyone have any information on this building?
Six sales in seven years seems like extremely low turnover for a building that has 84 units. (~1%) Are many of the units combined? Is the building listed under another address?
On that note, what is annual turnover normally in a co-op of this type? 10%? The units are small for large families, so I see it as the type of building a young couple might move before buying a larger unit when there are more children.
