Don't forget you would still have a $100 next-day availability requirement.
So you have:
$100 next day
$4,900 on 5th business day (under case-by-case)
$25,000 on 11th business day under large item exception
Of course if any other exception hold reason applies, you could hold the entire $30,000 under that exception hold to the 11th business day.
Now, having said all that, make sure you explain to your customer that making the funds available doesn't mean that the bank is saying the check they deposited is good and won't come back. You might want to explain to the customer about the various scams out there involving cashiers checks, especially in light of their curiousity about availability. That could be a warning flag that they may be falling victim to one of those scams. If you have significant doubts yourself, you may want to consider not accepting the cashiers check for deposit, but offer to send it for collection instead. You'll have to weigh the balance of your customer relationship with this customer in making that call.
