Sorry - to clarify - flip taxes were instituted to capture money from the rapid flipping that often took place just after buildings converted to cooperatives due to people selling who bought at 'insider' prices. Our building missed that wave. The sponsor currently owns aprox 1/3 of the apartments and will not be paying any tax yet will benefit form regular shareholders who get drained by this fee. I understand it is highly unusual for an older coop (30 years in our case) - to institute a flip tax when we already missed rapid turn-over, have 1/3 of apt who do not have to pay and can also anticipate very few sales in the near future. The excuse is that a tax is commonplace however I think this is partially a myth if you really examine finances and I do see many apartment listings advertising NO tax as a selling point.
