What is house-hacking and where to get info about it?

[Lance Bolen]

Hey everyone! I am Turing 18 and want to immediately get my real estate license. My initial thought was to go into wholesaling once I got it but many people here have told that’s not a good idea. People have recommended something called house-hacking. If someone could inform me on what this is and where to get really good info about whether it be a YouTube channel or course let me know!
