Even if the buyer was carrying only $20K in cash, that's still a large cash amount which is unusual. A typical person doesn't keep that much amount in cash, unless he totally doesn't trust the banking system or deals in shady/illegal business which uses only cash so it's untraceable. When you deposit $10K+ in cash (all at once or in a short period of time) into a PERSONAL bank account, the bank is required to report it to the IRS. Do it repeately and you'll be on some government watchlists.
