Good luck. Because of the drug war, doing anything with more than ten thousand dollars raises red flags all over the banking world. And paying cash for things over that amount does the same.
I had to wait over a week to clear a check from my inheritance because of that.
All to stop people from getting high...
There are ways around the foolish banking laws. You would be surprised how much cash gets moved around and who is moving it. In my business we often do very large deals (well over 10k)with foreign entities that have no way of paying for it in the US (we do not accept letters of credit). It is all cash on barrel head. We then process it according to the needs of our company. Only been tagged once and when the DEA guys saw what business we were in they said thanks and left.
