The utilities covered in an apartment's rent differ depending on the apartment complex. The lease should state which utilities are covered in the price.
Lights, water, cable, Internet and trash may be covered in the cost of renting an apartment. However, if all utilities are covered, the price of the rent may increase. The landlord can explain what is covered in the rent. They can also explain what companies should be contacted if the utilities are not covered by them.
Most apartments are unfurnished but generally include a stove and refrigerator. That should also be taken into consideration, when discussing the price of rent.
