One year leases on commercial office real estate?!? That's unheard of around here (Boston). You'll be lucky if you find a commercial landlord who will rent to you for 5 years instead of the more usual 7, 10 or 20.
Sorry for my lack of semantic nuance. Most of the leasers rely on payments from their subletters to pay their leases, so the effects will translate over in either case, just with more "buffer time".
There are also a fair amount of 1-year direct commercial leases, depending on the area.
Subleases are a different story, of course.
