Biggest difficulties that come with working with a partner?

[Ethan McRae]

My business partner and I are interested in househacking a multifamily together. Everything seems to be going great so far. We are working with an excellent agent and we are preapproved for a loan. 

However, I know that challenges will arise. Problems will come up no matter what and it is inevitable that we will disagree on some things moving forward. I am curious to know what some of the biggest difficulties have been for other RE investors who have worked with partners. More importantly though, I would like to know how me and my business partner can avoid difficulties that come with partnerships. 

Many many thanks!
