This sounds a bit different to me...but, in my opinion:
1. If you owned the property, the income was and is yours. By your father and sibling "taking" it, you are either gifting it to them, or paying them a management fee. You should be reporting the income and expenses related to this rental property. You cannot "assign" income to someone else.
2. Bank account...how do you receive the money? Here in the U.S. or overseas? If you currently don't have an overseas account, how do you get the money...or sibling get the money? Part of that is business convenience.
However, if you do have signature over a foreign bank account...there is certain reporting that needs to be done. First, on an income tax return, you have to answer yes to the question about a foreign account. After that, depending on balance(s), there may be more reports that are required to be filed...and if they aren't, there are stiff penalties.
