Quite honestly I do not think it is a good idea to attempt this. Ferrets are naturally meat eaters & in the wild rats,mice, etc are considered food for the ferret.
You could have a ferret in the same house with a rat but NOT in the same cage. If you were to get a ferret I would strongly suggest you keep the two separate. I have heard many stories about ferrets getting along with many other animals but NOT rodents... they almost always kill them.
I wish you the best of luck!
