Add more factors to the fairness calculators
I think it would be a great idea to add some other factors to fairness calculators in rent. Pets should be an extra charge, helicopter roommates should be an extra charge (you know, those ones who hound you about missing chores once, but miss doing their own all the time), taking over tons of bathroom space should be an extra charge (especially when only 1 is available in the whole house), smoking too close to the house and stinking it up should be an extra charge...etc. How can you calculate those things?!
Those are definitely all valid things to consider, but it’s hard to do with a calculator, and they should generally be dealt with on a case-by-case basis. The cost of a pet can vary widely depending on the type of pet, while the values of chores, bathroom space, and smoking depend a lot on who you’re living with, and should probably be discussed as a group. (Another request we hear often is parking, which has very different values depending on where you live.) Sorry we can’t be of more help!
