Partnering on a House Hack. best way to set up?

[Jesse Stephenson]

I have a brother in law that is young and single. He has good credit and a decent job. Never owned real estate yet. I was considering partnering with him on a house hack. Where I give him the down payment for instance on a 2,3, or 4 plex and he gets the loan in his name (lower down payment Better terms) and moves in and then overseas the rentals and doing upgrades and repairs. Should I have him pay rent for his unit into a repair fund maybe? And what would be a fair split of ownership etc 50/50? Also will a bank give him a primary residence loan with a partner on the deed? Also will IRS give him/ me tax free profit at the sale or how would that work? Any ideas on best ways to structure such a scenario?
