Adding some one onto my bank accoun in order to show proof of fun

[Jose Collier]

Hello, I am in the process of buying an investment home with my brother as a cosigner, his income is qualifying the loan, but I have the money for closing and down payment in my account. do to a bankruptcy I had that wont clear for a few months the sale is on hold. my brother will qualify on his own, but proof of funds is with me on the bank account only. Can we simply add him onto my account as joint holder in order for him to have proof of funds to close A.S.A.P and not run the risk of loosing the property? Thanks in advance!
