The short answer
If your HELOC payment is unaffordable, contact the servicer about hardship or modification promptly; a HELOC is secured by the home, even when it is a second lien.
What changes the answer
Find out whether the increase came from a variable rate, the end of the draw period, principal repayment or a balloon requirement. Those causes need different solutions. Read both the first-mortgage and HELOC obligations when assessing affordability.
A refinance may be available only if equity, credit and income support it. Ask the existing servicer about alternatives before assuming a new lender will approve the balance.

A practical next step
- Request the payment calculation and remaining draw or repayment term.
- Ask about fixed-rate conversion, modification or other available hardship terms.
- Compare the total secured payments with a sustainable budget.

Before you agree or pay
Do not treat a charged-off or dormant junior lien as automatically extinguished. A collection letter concerning an old home-equity loan deserves a document and legal review before payment or acknowledgment.

Keep the wider debt picture in view
A familiar monthly payment can change for more than one reason. Start with the contract and latest statement, then ask the servicer to explain the new calculation. Label the account as a revolving HELOC or an installment home-equity loan rather than relying only on the words second mortgage.

Questions worth asking

- Which part of my records changes this answer, and what should I do next?
Common questions
Is my first mortgage at risk if only the HELOC is unpaid?
A HELOC is secured by the home, so default can create foreclosure risk even when the first mortgage is current. Lien priority and the holder’s available remedies matter. Contact the HELOC servicer early and treat any legal notice as time sensitive.
Where should I start?
Request the payment calculation and remaining draw or repayment term. Ask about fixed-rate conversion, modification or other available hardship terms.
Does using this guide change a payment or legal deadline?
No. Reading a guide or completing Find My Options does not file an appeal, answer court papers, stop collection, or create an agreement. Use the actual notice and the responsible court or agency to verify deadlines.
