Starting out in a community property state

[Abraham Orozco]

Wanting to buy a house with my brother to start acquiring houses. He is able to move every 12 to 16 months. He will be living there as he rehabs the property.

I am married, and my wife does not want to have anything to do with acquiring more debt or me being in another mortgage and I live in Arizona a community property state.

These are my questions.

How is a join account seen if is my brother me on it? Would my wife have to be involved if I'm not on the mortgage.

How long would the funds need to be there, to satisfy any lender requirements?

How big of a gift can he receive from me for a down-payment?

Any other ideas are greatly appreciated.
