I rent a room and bathroom in my house to a guy for $400/month which includes all utilities. He’s leaving for 2 months this summer to go home and I don’t know what to charge for rent while he’s gone. He won’t be there, but all of his things will and I won’t have access to the room or bathroom while he’s gone. I don’t know what’s fair… if he were renting an apartment there’d be no room for negotiation. He thinks it should be free! What is fair guys?
