Subordination is the workaround. A senior lienholder agrees to drop to a lower priority on a specific asset so a new lender can take first position on it. When an existing blanket lien is blocking a new secured deal, subordination is usually how it gets unblocked without forcing the old debt to be paid off first.
Here is how it plays out. The new lender reaches out to the existing lienholder and asks for a subordination or intercreditor agreement. The existing lienholder does its homework first. It wants to know the size of the new financing, which collateral is involved, and how healthy the business actually is. If it is comfortable, it signs a formal subordination agreement saying that for a defined piece of collateral, maybe one specific machine, maybe all the accounts receivable, the new lender now ranks ahead of it.
Whether you can even get subordination depends heavily on who holds the lien. Established institutional lenders, the banks, equipment finance companies, and SBA lenders, handle these requests all the time, especially when the relationship is in good shape and the new loan makes sense for the business. Alternative lenders are a different story. MCA providers and fintech lenders rarely subordinate, partly because their model was never built around the kind of multi-lender arrangements that require it. Some go further and flatly prohibit subordination right in the funding agreement.
What does a lender want in return? Often nothing formal, as long as the ask is reasonable. A lender sitting on a $50,000 balance is not going to torpedo a $500,000 equipment purchase that helps the business generate revenue and pay everyone back faster. But a lender that suspects the new financing will strain the borrower's cash flow, and raise the odds of default, may say no or attach conditions.
Here is the part owners miss. Figure out which of your lenders will and will not subordinate before you take the original money, not in a panic when you suddenly need it. Read the subordination provisions in the funding agreement before you sign. If it bars subordination outright, or demands lender consent for any future lien, know exactly what that does to your flexibility for the entire life of the deal.
