You want to refinance your first mortgage to lock in a lower rate, but you already have a HELOC sitting in second position. Without the right paperwork, that HELOC could automatically move into first position when you pay off the original loan—and your new lender won't close until the lien order is fixed. That's where a subordination agreement comes in.
What a subordination agreement does
A subordination agreement is a legal document signed by your HELOC lender that keeps the HELOC in second lien position after you refinance the first mortgage. Lien priority matters because the first-position lender gets paid first in a foreclosure. Your new mortgage lender needs written confirmation that the HELOC will remain subordinate, or they won't fund your loan. Consult a CPA or attorney; this is not tax or legal advice.
How the process works
Once your refinance is in underwriting, your loan officer requests a subordination agreement from the HELOC lender. You'll typically need to provide the HELOC account number, a copy of the original HELOC note, and details about the new loan. The HELOC lender reviews the request to confirm that the new loan amount doesn't exceed the original first mortgage balance by too much and that you're not pulling out excessive cash. Most HELOC lenders charge a processing fee—anywhere from $50 to $500, depending on the institution. Some credit unions process subordinations internally within a week; large banks may take three to six weeks. The subordination must be signed and recorded before your refinance can close.
When the HELOC lender says no
Occasionally a HELOC lender refuses to subordinate. This happens if you're refinancing into a much larger loan amount, if your credit or property value has deteriorated significantly, or if the HELOC lender's internal policy has changed. If that occurs, you have three options: pay off the HELOC entirely at closing (using cash or refinance proceeds), apply for a new first mortgage large enough to pay off both liens and replace them with a single loan, or shop for a different refinance lender willing to accept a higher combined loan-to-value ratio. These figures are illustrative; rates and products are subject to change and this is not a commitment to lend.
The Alliance take
Subordination adds a step to your refinance timeline, but it's routine. Start the process early—ask your loan officer to request the subordination as soon as your appraisal is ordered. If your HELOC is with a community bank or credit union, call them directly to confirm their timeline and fee before you lock your rate. Most subordinations go through without drama, and keeping that HELOC open preserves a ready line of credit for future needs. Questions about lien priority or timing?
