<prompt> Human: So my GF and I are in the process of trying to get new roommates rent is 1200, there are two rooms, each room has a bathroom, shared kitchen, laundry, livingroom. Previously we were splitting rent with a friend of my GFs the number of people so everyone paid 400 per month. But Im also thinking now that it may not be fair since we are paying 800 for our room, and they would just be paying 400 for their room. If we charge by the room each room would be 600 per month.Side issue: We already posted an ad at 400 per month and had quite a few people respond. Would it be sketchy, or rude to change the price to 600 per month on them?Side issue: We already posted an ad at 400 per month and had quite a few people respond.
