I am a rental sole proprietor LLC with expenses such as truck, phone, home office. Can I deduct this under E rather than C? If so, how - against which property?

I have done Schedule C in the past, but if I have no income on the C since it is all reported on the Schedule E, what I am writing those expenses against? Should I instead write general (ie non-individual property specific) expenses such as the truck against a specific property or divided equally under "other expenses" in each?
