Generally, a sublandlord cannot charge a subtenant more rent than what they pay to the landlord. If a sublandlord is renting out their entire rental space, they often charge 80 to 100% of their rent to help recoup as much money as possible. If a sublandlord is subletting a portion of the property, determining a fair rent price depends on the amount of space they are supplying. If you’re unsure how much rent to charge, research the costs for similar properties in your area. Also, consider any perks your space offers to a subtenant (such as location, amenities, or furniture) and whether this should be reflected in your rental price.
