Second mortgage: what it means

A second mortgage (or junior lien) is a loan you take out using your home as collateral while you still have another loan secured by it. Home equity loans and HELOCs are common examples.

In Spanish it is

Segunda hipoteca

Also written as: junior lien · subordinate lien · subordinate mortgage

The full explanation

It is called "second" because, if you stop paying and the home is sold to pay the debts, this loan is paid after the first one; if there is not enough money, the second lender may not get everything it is owed. That is why it often has a higher interest rate. It adds to your total debt and, if you cannot repay it, you could lose your home.

An example

Alberto already has a mortgage and wants another loan with the home as collateral. Before deciding, he adds up both monthly payments and checks whether he could cover them if his income dropped.

You will see it in…

  • Your credit report

Words that go with it

You will rarely see this word alone. These are the ones that show up with it on the same papers.

A grandmother pushes her grandson on a playground swing.

Still confused by a paper?

A HUD-approved housing counselor can walk you through it. Agencies usually charge little or nothing, many work in Spanish, and they do not sell you anything.
