<prompt> Human: My father has been in real estate and working for many years of his life. He has accumulated 7 rental properties, with 4 of the homes completely bought in cash. He mistrusts banks and has his cash, about 180k, lying around in secrets spots that only he knows about. He has accumulated this money all legally by the way. I lose sleep every night at the thought of his money losing value by just being stored away and not gaining any interest. Also, I am afraid that one day his money will be destroyed by fire, eaten by mice, or stolen by burglars, etc. He doesnt even own a safe to store this money in...I have done some research about online savings accounts with higher interest rates. Ally Bank, 1.45 interest and so forth. However, my dad is worried that depositing a large amount of money would be suspicious. What are his options? My dad is 48 years old, has no 401k or IRA savings account. He would be considered very old school, and believes his money and rental properties he has accumulated and Social Security checks when he retires will cover him for the rest of his life... he has about 80k in his checking as well. I just want my dad to be financially okay when he does get older and retires.  <response>: Your dad is financially OKHes making money off his rentals to the point he builds up piles of cash.As for his paranoia, maybe hell get over it when he is burgled and loses all his cash
