timing the credit increase request for unsecured Biz line of credit

[Luis Montanez]

Around February I requested and was approved $15k unsecured business line of credit. I have been using it responsibly and currently have an unpaid balances of $1,500.  

The question is, when would you request a credit increase?  Would you do it know with the unpaid balance? Or would you pay off the balance first before requesting the increase?

I have an excellent credit but low on cash so will have to wait about 3 months if I deicide to pay of balance first.
