california: I am trying to figure out our prorated rent because I think it should be based on the rent divided by how many days there are in a month and my landlord says it should be just 30 days. Anyone out there have any info with regards to prorated rent formulas or laws or guidelines in California? Thanks!|||Your landlord is correct. There are only 360 days in a banking or tax year. It's not the same as a calendar year of 365 days. This allows for 12 equal months/payments of 30 days each. Do you pay less rent in a 28 or 29 day month than you do in a 30 day month? Or more rent in a 31 day month than you do in a 30 day month? Of course not.|||Rent is usually prorated when you move in, but not when you move out. If you have a written lease, if you read it, the landlord can legally NOT entertain proration of rent. However, if you do not have a written lease, it is prorated. There is no law that states in a written lease that a landlord must prorate it...that is why you can't find it.|||Your landlord is correct. All months have 30 days for legal purposes.
