Ben Affleck And Jennifer Lopez Visit New $50 million Bel-Air Estate

Jennifer Lopez and Ben Affleck are already taking steps to make their new mid-$50M house a home ... visiting the property with family and snapping pics inside the massive estate.

We're told the two spent more than 2 hours at the Bel-Air estate over the weekend, but they didn't go alone -- J Lo's daughter, Emme, tagged along -- as did the couple's security team.

Ben was spotted snapping pics inside the 20,000 sq ft pad, just before heading out again with the fam. Unclear if Ben wanted the pics for some design ideas, or just to show friends ... but either way, the home is spectacular.

The sale is significant in more ways than one for the couple ... you gotta assume there's an engagement on the horizon followed by an over-the-top wedding.

Of course, $50M can get you a lot -- even in Bel-Air -- the house is decked out with a home theatre, a gym, multiple kitchens, an infinity-edge pool with a view ... just to name a few.
