I have always used by end of business which normally means by 5pm. I think that it depends on who you are sending the email to. If it is a superior you might want to reconsider and define an exact time deadline.

Depending on what your purchase contract stipulates and whose fault the delay is, if you don't close on time, you may have to pay the seller a penalty for every day that the closing is late. The seller could also refuse to extend the closing date and the whole deal could fall through. In a best-case scenario, the seller could simply agree to extend the closing date with no penalty. After all, if the deal doesn't close, the seller will have to start all over again, too. Training for a Successful Finish.
