What to do with Wallpaper

[Matthew Rembish]

So I'm in the process of evaluating a possible flip opportunity but the only thing that is scaring me is the fact that most of the walls are covered in wallpaper. Does anyone have any recommendations for what to do with it? Is there an easy way to remove it or cover it?

I would really prefer not to have to replace the sheetrock. As I'm sure you can tell, I don't have a lot of experience with wallpaper so any feedback is very appreciated. Thanks!!!
