Someone's Getting Screwed And It Ain't The Tenant

This 2 bed apartment for sale doesn't have anything special about it except for this little note at the bottom:

Tenanted till Nov 2012.

November 2012? That's over four years away! Now if any tenant with half a brain signs a lease agreement that long then I sure hope that they got a decent rent discount,wrote into the lease agreement a rental escalation clause that is below inflation and some serious concessions (i.e. rent back) if the lease is cut short.
