As of my last knowledge update in January 2022, I do not have information about Rick Ross buying Meek Mill’s Atlanta mansion for $4.2 million in cash. Real estate transactions involving celebrities can occur, but the details may not always be readily available or accurately reported.

To confirm the latest and most accurate information about Rick Ross’s real estate acquisitions, including any potential purchase of Meek Mill’s Atlanta mansion, I recommend checking recent news sources, official statements from the parties involved, or reliable real estate databases for the most up-to-date details on the transaction.

Celebrities often engage in high-profile real estate deals, and if this transaction has occurred, it might be covered by reputable news outlets or confirmed through official channels. Real estate transactions can be subject to change, and new information may have emerged since my last update.
