You should bear in mind that at least the banks I know will check the new owners of the company and may ask for additional security in order to maintain the credit line for the company after a sale.
For instant we have a 1985 aged company for sale which is incorporated in Cyprus, it has all annual reports etc. and a established bank account and credit line, however, if the new owner want to take over the company and need the credit line the bank will most often have several demands / requirements in order to keep it.
