I've been studying for the past 4 month my Real Estate Sales course and been reading REI books, listening to BP podcasts and gaining as much information as possible.

I definitely would love to gain a mentor, sooner than later.I listen to the Bigger Pockets Podcast regularly now.

Looking to gain as much knowledge as possible about exactly how REI will benefit my family and peers.

I was having an informal conversation with a lender yesterday and he mentioned that house-hacking can provide the benefit of more favorable lending terms, but I didn't get the full details...I'm seeking insight as to whether purchasing a MFR as a personal residence (house hacking) can allow a smaller down payment (20%) or more favorable interest rates than if purchasing a MFR and renting out all units.

I am still trying to gain knowledge about the different loans out there and what would work for us, We would hope to network enough and find an investor to partner with that can help us on the financial side.

You'll gain some insight into what the City Might consider. 

Yes, there are of benefits to the 529, much like there are benefits to IRAs and 401ks, but I trust you're finding here on BP that wealth can be, and is, amassed more quickly when you take control of things.
