If a person is deported from US, the ownership of his property (homes, cars, bank accounts) will not be affected. He may Sell property and transfer funds (via SWIFT code) before leaving.
If he has no time to sell the property, he can assign a trusted agent (family or friend) as Power of Attorney (POA) and grant the POA authority to manage finances, sell property, pay bills, and handle banking; or he also can set up a trust with a trustee to manage assets for his benefit.
