Mortgage CoSign Question

[Noah Stout]

Novice Here:

Im curious if its possible or wise to have my brother cosign a FHA mortgage with me?
The property would be a duplex that I House hack, ideally using a FHA loan. I am only asking bc my w2 income is not sufficient enough to get a loan on the type of property we want. Is there anyway to take him off the loan after a year so he doesn't have the added DTI?

Down the road we plan on owning several more rentals together in a LLC.

Any thoughts/insight/advice is greatly appreciated!
