Mel Gibson's Malibu estate -- where he and Robyn raised their 7 children -- has just been put on the market again for an affordable $14.5 million.

Mel and Robyn put the house on the market a year ago for $14.5 mil, but took it off recently.  One source familiar with the home tells TMZ, "They wanted to spruce it up and re-list it." 

The property is 5,403 square feet, with 6 bedrooms in the main house.
