Real estate fund manager Grant Cardone has gone from suing a critic to being sued by his own investors, which is bad news for Cardone and a warning sign for anyone with money in his funds.

• Cardone sued YouTuber Kevin Paffrath, but his own attorney dismissed the case in court after the judge signaled it was going badly.
• Cardone is now being sued for $250 million by fund investors who say he promised returns and did not deliver.
• Cardone publicly posted his own deposition testimony, which appears to back up earlier suspicions about how his funds were run.
• The reversal undercuts Cardone's push to silence critics and puts a spotlight on his fund promises.

Outlook: The investor lawsuit will likely drag on and draw more scrutiny to Cardone's real estate funds and their marketing claims.
