Jenni Rivera -- Kids Moving On … Time to Cash In On Mom’s Estate

Jenni Rivera's family is ready to unload one of her prized possessions -- the massive estate she designed 3 years before her death ... and they're hoping to get $4.5 mil for it.

Jenni’s dream home sits on 4 acres of hilltop land overlooking Encino, CA. The estate has 7 bedrooms and 10 baths including marble floors and a double wrought iron staircase.

The legendary Mexican singer originally bought the property in 2009 for $3.3 mil, but sunk another $500k worth of personal upgrades into the place. Right now Jenni’s kids are living there, but we're told they're ready to bolt if the right buyer comes along.
