Bought a house cash, need cash out refi advice!

[Jessie Lozano]

Hey BP. I've finally found a property to get my feet wet in REI. I've ran all my #'s on this deal and it's meets all the ROI requirements I have made for myself. An agent friend found this deal when he picked up a client that was going through a divorce and needed to unload a duplex fast and for cash. I didn't have the full amount of $ on hand so I solicited by brother and sister to go in with me. We are about to get into contract and I want to start looking at a cash out refi and start the BRRR process.

All three of us would be on the title. Does anyone have experience in something like this? Would we all need to be on a loan application or can I carry the note under my name with their approval (I have the best credit score and a very low DTI ratio)?
