Overmount or undermount sink with younger tenants?

[Tarun Kapoor]

I am installing granite in my kitchens. My install guy will charge $75 less if he doesnt have to polish the sink cut for an undermount sink. I am not worried about the $75 right now, but more worried about the long term costs of an undermount sink.

From what i have gathered by reading forums and google, the undermounts take much longer to uninstall if there is a problem. Plus i heard there can be leakage. My tenants are 25-30 yr olds who wont take the best care of it. So i thought i'd ask if people run into any issues with undermount sinks in the long run with younger tenants.
