Holding N-1 of the A shares and a thousand of B-shares isn’t so bad for most such people.
I think you meant fifteen hundred B shares.
I think he probably did mean a thousand: if you don’t need $482 000 right away, convert one A-share to 1500 B, sell 500 B for $160 000 cash to pay for the property tax on your mansion (which is why you are doing this), and keep the other 1000 B-shares for the coming months’ expenses.
