If it is at GoDaddy you can not change accounts within 5 days period. Otherwise, if it is anywhere else you can transfer it to an account with that registrar, but you can not transfer it to a different registrar until 60 days.
Also, the Sedo buyer will have a choice to either have it transferred to Sedo's account at that registrar and get the name or wait the 60 days. So if they choose to wait your money could end up being tied up for about 60 more days.
So the answer is basically, yes... it is okay....
