Past due rent or late payment?

Any rent or other debt not paid to PuebloPlex within 30 days is considered a late payment. Late payment of rent and other debts owed to PuebloPlex by Sublessee will be subject to a penalty charge of an interest rate equal to the prime interest rate prevailing on the date such payment is due plus 6% per annum, plus all recoverable administrative and legal costs, including attorney’s fees, required and incurred by PuebloPlex to process and collect such late payments and penalties. All penalties and interest will accrue from the date due and continue to accrue until the debt is paid in full.
