Second mortgage advanced as a fixed lump sum instead of a revolving credit line.
A closed-end second mortgage is a second mortgage advanced as a fixed lump sum instead of a revolving credit line.
Closed-end second mortgage matters because not every second mortgage gives ongoing access to credit. Some second liens are fixed loans with a defined amount, repayment term, and scheduled payment.
It also matters because borrowers often use “second mortgage” and “HELOC” interchangeably. A closed-end second mortgage behaves more like a fixed installment loan than a reusable line of credit.
Borrowers encounter this structure when comparing a Home Equity Loan with a Home Equity Line of Credit (HELOC).
The term becomes practical when the borrower wants one known amount rather than the ability to draw more later.
| Structure | Borrower-facing difference |
|---|---|
| Closed-end second mortgage | Fixed amount advanced up front |
| Open-End Home Equity Credit | Revolving access to an approved line |
| Home Equity Loan | Common closed-end home-equity product |
| HELOC | Common open-end home-equity product |
A homeowner borrows $35,000 against equity and receives the funds as a lump sum with a fixed repayment schedule. That loan is a closed-end second mortgage.
Closed-end second mortgage differs from Second Mortgage because second mortgage is the broader lien-position category, while closed-end describes a fixed, non-revolving loan structure.
It differs from Home Equity Line of Credit (HELOC) because a HELOC is revolving and can allow repeated draws during the draw period.
It also differs from Cash-Out Refinance because a closed-end second mortgage usually leaves the first mortgage in place instead of replacing it.
