How much would it cost (Part itself and Labor combined) to replace rear wheel bearing on 1998 BMW 328ic?

I'm thinking about buying a 1998 BMW 328ic sport coupe. I can get a good price on the car, but it has a bad rear wheel bearing. I was just wondering if I could buy the car and replace the bearing, and still come out on top? Thanks.How much would it cost (Part itself and Labor combined) to replace rear wheel bearing on 1998 BMW 328ic?ok
