Anyone else got screwed by misrepresentation of property taxes?

Hi There, My husband and I recently purchased a new condo in Brooklyn and received the shock of our lives with a tax bill double the estimate listed on the advertisement and offering plan. We wonder if there are any other folks out there who encountered the same issue, and how they’ve dealt with it? We are really pissed off with our broker and developers for falsely quoting tax prices that are just plain lies and wrong. They should not be allowed to do this. We understand that the language throughout reads “estimate” but to be 100% off is simply insane. I cannot believe there is really no recourse? Who is responsible for the interest of the buyer and clearly defining a potential disastrous outcome like this? I would appreciate anyone else to share similar stories or advice. Thank you.
