What gears to support a walking video ?

This real estate video https://www.youtube.com/watch?v=dktkJXp6LNc is amazing. It was smooth and stabilized while videographer walking through narrow room doors. At first I thought the camera on dolly but it's unlikely to go through small doors or walking up steps between floors. Just wondering what stabilizer was used in shooting this video ?

Steadicam/Glidecam (though the first shot is car/truck mounted and 2nd shot is aerial-gyro drone).

This one is similar, I think you´ll find the "making of" parts interesting.

Wow, such a Hollywood movie production, I guess the realtor paid certain amount of money to get this 3-4 min done.

Probably. I'm guessing ~$7500 (~$2k/finished minute or slightly less).
