Can you refinance your first mortgage and keep your HELOC?

What does HELOC subordination mean?

A lien is a claim against the home securing a debt. Your refinance lender generally wants the new mortgage ahead of an existing HELOC in lien priority. Subordination lets the HELOC remain behind that replacement mortgage. It addresses the order of the claims, rather than paying off the HELOC balance.

For loans sold to Fannie Mae, existing subordinate financing generally needs a signed and recorded resubordination agreement when the first mortgage is refinanced. There is an exception when applicable state law preserves the required position and its conditions are met. Let the refinance lender and title team determine what your transaction needs.

Treat the request as a review, not an automatic approval. PNC's public FAQ, for example, says the refinance lender submits information for PNC to evaluate. Its published target is two to three weeks after all required documents arrive. That is one lender's target checked November 11, 2026, not a universal deadline or a West Capital Lending promise.

CFPB cautions that a HELOC lender may refuse the request, which can make paying off the line necessary for the refinance. If that happens, compare a revised payoff plan before committing. Do not assume that meeting the new mortgage lender's guidelines also means the HELOC lender has agreed.

Separate the lien decision, loan approval and account choice

1. Lien position: Can the existing HELOC stay behind the proposed new mortgage, and what documentation is needed?
2. New-loan eligibility: Does the refinance qualify with that HELOC still attached to the home? A subordination agreement alone does not answer this.
3. Account choice: Do you want to keep the line, permanently reduce it, or pay it off and close it? Ask for a comparison before authorizing a change.

For an eligible Fannie Mae loan, the full HELOC limit generally enters the home equity combined loan-to-value ratio (HCLTV), even if the balance is zero. A documented permanent reduction can change that calculation. The unused HELOC guide explains the ratios and required-payment review. Other programs and individual lenders can differ.

Compare keeping the line with paying it off

If you keep the HELOC, compare the new first-mortgage payment plus the HELOC payment. Review the line's remaining draw period, repayment schedule, rate terms and fees. Keeping it open does not create a fresh draw period. The end-of-draw guide explains why the later payment deserves a place in your budget.

If the refinance will pay off the HELOC, ask the new lender to classify that transaction before comparing quotes. Fannie Mae generally treats paying off a second lien that did not fund the purchase as cash-out, even when you receive no extra spending money. Its purchase-money second-lien rules differ. Program-specific exceptions need review.

For each feasible path, write down the total new debt, cash needed at closing, combined payment, fees and payoff dates. Moving a balance into a longer mortgage can lower the monthly requirement while extending repayment. Use the refinance calculator for an initial comparison, then include HELOC costs it does not model. The calculator does not decide lien priority or loan eligibility.

If you close the line, a future replacement would need its own approval and terms. CFPB notes that HELOC plans can also have fees and initial or minimum borrowing requirements. Avoid a plan that depends on automatically reopening the same credit later.

What to confirm before setting the closing date

• Send the current records: first-mortgage and HELOC statements, credit limit, balance, agreement and details of any other liens.
• Describe the exact refinance: proposed loan amount, use of proceeds and whether the HELOC should stay open.
• Identify who submits the request: confirm the HELOC servicer's process, required documents, fees and current turnaround with your refinance lender.
• Match the timelines: ask whether the expected review fits the proposed closing and rate-lock expiration, including what happens if it takes longer.
• Confirm the final account outcome: if the HELOC stays open, confirm the required lien-priority documentation and separately document any permanent limit reduction. If it closes, confirm payoff, closure and the required lien-release steps.
