Hey @Mitch Jorgensen welcome to BP! You're absolutely on the right track - house hacking can save you thousands of dollars every year in rent, allow you to build equity, benefit from appreciation, and you gain experience as a landlord without the risk of a sole investment property.
Similar to yourself, I recently graduated with a Finance degree and just bought a 3/3 duplex to house hack in Milwaukee. To give you some perspective, the PITI on the duplex is $1,275 and the other unit will rent for around $1,050. I won't be completely living for free, but having another roommate will take care of it.
One thing I would do immediately is get connected with an experienced agent and start analyzing deals every day. When it's time to pull the trigger, you'll be confident that you're buying a good deal. It seems we're in a pretty similar situation in life so feel free to shoot me a message if you have any questions.
Hope this helps!
Drew
