Keep Your Second Lien or Pay It Off?

If you have a HELOC or second mortgage, refinancing gets more expensive — lenders add a pricing adjustment and use your combined LTV for pricing. Sometimes paying off the second with a cash-out refi costs less overall. Let's find out.

Understanding Your Second Lien

HELOC (Home Equity Line of Credit)

A revolving credit line secured by your home. During the draw period (typically 10 years), you make interest-only payments and can borrow up to your limit. After the draw period ends, it converts to a repayment period — the balance becomes fully amortizing over 15-20 years, and payments jump significantly. The rate is variable (tied to prime), meaning your payment changes as rates move. At the end of the term, any remaining balance is due as a balloon payment.

Fixed-Rate Second Mortgage

A one-time lump sum with a fixed rate and fixed payment. Simpler than a HELOC — no draw period, no rate changes, no balloon. But the rate is typically higher than a first mortgage because the lender is in second position.

Why Paying It Off Might Make Sense

  • Eliminates the variable rate risk (HELOCs can get very expensive when rates rise)
  • Avoids the balloon payment surprise when the HELOC draw period ends
  • Removes the subordinate financing pricing penalty on your first mortgage
  • Simplifies to one payment instead of two
  • No subordination fee (~$200) and no waiting for the second lien holder to approve

Why Keeping It Might Make Sense

  • Cash-out refi means a larger loan amount and higher first mortgage payment
  • Cash-out has its own pricing adjustment (potentially worse than the sub financing hit)
  • If your HELOC balance is small, the pricing impact may not justify closing costs
  • You keep access to the credit line for future use
  • Cash-out refi above 80% LTV is restricted or unavailable for conventional loans

Why does keeping a second lien cost more on the first? Two reasons: (1) lenders use your combined loan-to-value (CLTV) — first mortgage plus second lien divided by property value — for pricing, pushing you into a worse LTV tier. (2) There's a separate pricing adjustment just for having subordinate financing, typically 0.625 to 1.875 points depending on LTV. These stack on top of each other.
