Backstabbed outlets in a flip? That's the laziest shortcut there is. Those spring clips lose grip over time and the next thing you know a kitchen appliance is arcing behind the drywall. Did you pull the cover off any of them or just spot it from the outside? Curious if they at least used 12 gauge on the kitchen runs or cheesed it with 14. And what else did they cut corners on, because somebody who backstabs is usually hiding three more things.
