Too lenient for our bank's blood; we would not do a 15 year loan for working capital purposes. Business lines of credit are typically for working capital and extending the line in full makes the bank an equity partner in the business, not a lender. Since we don't get compensated as an equity partner, we don't lend like one. Now, that is the lender's statement, you would get a distinctly different statement from one of our loan review folks. That being said, I applaud your bank for completing this analysis to begin with (many banks won't).
