Unlocked verizon note 4 on swappa

Maybe I have missed it somewhere in the forums but I'm looking at upgrading out of my note 3. I lost root a while back. Now in my search for the next rootable phone I've come across a lot of UNLOCKED NOTE 4 VZW . What does that mean when it comes to root-ability? I understand you can unlock bootloader and you can unlock sims. What does it mean to advertise a unlocked phone and will it be rootable.
