During rentals, one or two month rent is required in security deposit. In some cases you may have to pay a 2 month deposit instead of one if it’s a negative output. It cannot be paid any later than 10 days before the set move in date according the your lease. If you would sign a lease sooner than 10 days prior to starting date the deposit invoice will be due within 2 days. You can always see your upcoming payments under "leases" .
