I just saw this exact same model, in similar shape, at the thrift store for $30. The frame and drivetrain caught my eye, but the chain stay brake and lesser components made me question whether it would be worth it. I'm sure it would make a fine all-around bike, but does it have the used online market value of, say, a Stumpjumper or lugged Trek MTB of similar vintage? My gut tells me no, this bike is more like a Schwinn high plains: nice frame, but overall unremarkable bike that's never going to fetch the resale value of those other models.
