Zsa Zsa Gabor's Husband Has to Move Out of Their Home

Zsa Zsa Gabor struck a sweet deal on her Bel-Air mansion, and now that she's died ... it means her widower has to find a new place to live ASAP.

Sources close to Zsa Zsa tell TMZ ... Frederic Prinz von Anhalt has to move out of the home he shared with her because he has no ownership rights. Gabor actually sold the mansion in 2013, but made a "life estate" deal which allowed her to live out her days there. Hugh Hefner has the same setup at the Playboy Mansion.

We're told the buyer has been great to Zsa Zsa and her husband, so Frederic isn't being rushed out -- escrow still has to close and he'll likely have 90 days to find a new pad. Zsa Zsa's realtor, Roger Perry, is currently helping him with that.

Our sources say Gabor's home was listed for $14.9 million, and sold to a commercial real estate mogul who plans to renovate it, or possibly tear it down.
