Just get an umbrella and keep the home in your name. 

Quote from @Derrick Roland II: "but based on my pre-approval"  This is the most important phrase of your post.Where did you get that pre-approval? 

Everything on my side was set to close, and then today the seller is refusing to close on Monday as they have not moved a few pieces of furniture they were supposed to get movers for.

I think we will see more "adult" families living together...kids move back in or parents move in with kids.The traditional apartment model was based on 12month leases, but jobs are not always 12 months and people want flexible terms, so co-living often offers that.Seems like younger people between 20-30 and some other age groups don't want to get married and start that housing pathway our parents and grandparents took.   

At the same time you're figuring that all out, get your brother and friend under a lease, or at least, a written agreement both parties can agree on.

Look for warning signs like wall cracks, misaligned doors, or uneven floors, and always get an inspection from a structural engineer (not just a foundation repair company).

You never get hurt taking a profit.  

- That could get you a Class A duplex or Class B 4-plex in the suburbs of Detroit. - You can get more units in the City of Detroit, but you will need to understand the City's demographics or you'll get taken advantage of.City of Detroit has 183+ residential Neighborhoods.

He gets half and we get half. 

Do it yourself and get good at it.
