How loan subordination affects your mortgage position

Loan subordination changes lien priority on your property so a new loan (for example, a HELOC or a cash-out refinance) can take first claim to the collateral. If your lender signs a subordination agreement, the older loan remains on the title but becomes subordinate (lower priority). Lien order matters because, in a sale or foreclosure, senior liens are paid first.

How the process typically works

  • You apply for a new mortgage or HELOC. The new lender orders an appraisal and title search.
  • The title search shows existing loans. The new lender asks the current first-mortgage lender for a subordination agreement so the new loan can be in first position.
  • The first lender reviews the request — often checking credit, the appraisal, and combined loan-to-value (CLTV).
  • If approved, the first lender signs a subordination agreement and title is updated. If denied, the new lender may require the existing loan be paid off or ask for different terms.

In my practice helping homeowners with refinances and HELOCs, the most common hold-up is lenders refusing subordination when CLTV is high or if the original mortgage has restrictions. Lender policies vary, so early communication is essential.

Why a lender might refuse

Lenders can deny subordination for business reasons, not as a personal slight. Common reasons:

  • Combined loan-to-value (CLTV) is too high for the lender’s risk tolerance.
  • The original mortgage has a clause that restricts subordination (rare but possible).
  • The borrower’s credit or income situation deteriorated since the first loan was made.
  • The first mortgage servicer requires payoff on refinance-type transactions (some servicers prefer to be paid off rather than subordinate).

If a first lender refuses, options include paying down principal to lower CLTV, asking the new lender to accept second position at better terms, or arranging a simultaneous close where the first mortgage is paid off at the new closing.

Real-world example

Sarah wanted a HELOC for renovations while keeping her original mortgage with Bank A. Bank B wanted first position, so Bank A reviewed Bank B’s loan package, the appraisal, and Sarah’s credit. Because Sarah’s combined LTV was 70% and her credit remained strong, Bank A signed a subordination agreement. If her CLTV had been above the lender’s threshold, Bank A likely would have declined.

Who is most affected

  • Homeowners applying for HELOCs, second mortgages, or partial cash-out refinances while keeping an older mortgage.
  • Borrowers with high CLTVs, recent credit issues, or loans serviced by a lender with strict subordination rules.

Practical steps to increase your chances of approval

  1. Ask the new lender early whether it requires first-lien position or if it will accept a subordinate lien.
  2. Provide a recent appraisal and a current title report to the first lender.
  3. Improve CLTV by paying down principal or increasing your down payment when possible. Many lenders prefer combined LTVs in the 80–85% range or lower, though policies vary.
  4. Keep credit and income documents ready — the first lender will often reassess borrower risk.
  5. If the first lender refuses, consider a simultaneous close or a cash-out refinance that replaces the first mortgage (see our Refinance Checklist for documents lenders commonly ask for).

Common misconceptions

  • “Subordination is automatic.” It is not — it requires a signed agreement and lender approval.
  • “Subordination changes the loan terms.” Priority changes; loan interest rate, balance, and payment schedule remain set by each loan’s contract.

Alternatives if subordination fails

  • Have the new lender accept a second position (may mean higher rate or different terms).
  • Pay off or refinance the first loan so the new lender can be first.
  • Use other credit sources (unsecured loan, personal loan) if home-secured options are blocked.

Frequently asked questions

Q: How long does a subordination decision take?
A: It can take a few days to several weeks depending on lender responsiveness and whether additional documentation or a title update is required.

Q: Are there fees for subordination agreements?
A: Some lenders charge administrative or recording fees; ask your servicer up front.
