Sure, you can sue. I hope you have $25k for an initial retainer to give your attorney.

With regard to the real estate disclosures, that is a document you completed, right? Questions like "has the roof ever leaked", etc. In most jurisdictions these days if there is a hidden defect that a buyer could not readily observe, you knew about it, and didn't disclose it, you're on the hook. So yes, it's a CYA document - but it's your "A" that's being protected. If the disclosures were inaccurate, that's on you.

As far as your "kicker" goes, the company would have been subject to all sorts of legal ramifications if it has illegally disclosed to you the negotiations for its sale to you.

The rest of your "issues" sound more like they fall in the category of disappointment. If you can point to a specific objective misrepresentation the company made to you, on which you relied, then there could be some valid claim of fraudulent inducement. But you'd better have far more than your personal disappointments as evidence.
