Prorating is used to calculate your move-in rental cost because the first month you rent from us may not be full length. Rent is always due on the 1st after initial move-in, but your lease can start any day of the month. Prorate means that if your lease begins after the 1st of the month, you only pay for the days actually rented that month. As a policy, we prorate in any rental that begins after the 1st of the month, but we do not prorate out for a partial month when you move out. Our staff is unable to refund partial rent if you move out of your unit mid-month. We recommend moving out of your unit at the end of the month so you are using your unit all the days you paid for.
