Second Mortgage Versus Home Equity Loan
June 9, 2003, revised August 30, 2003, November 29, 2006
"What are the differences between a second mortgage and a home equity
loan?"
The terminology is confusing. A second mortgage is any loan that
involves a second lien on the property. Some second mortgages are for a
fixed dollar amount paid out at one time, in the same way as a first
mortgage. As with firsts, such seconds may be fixed-rate or
adjustable-rate.
The seeds of confusion were sown in the 1980s when second mortgages
appeared that were structured as a line of credit rather than for a
fixed dollar amount. Borrowers could draw up to some amount, when and as
they pleased. These loans were called "home equity loans" or "home
equity lines of credit", with the latter shortened to HELOC. They are
always adjustable rate.
I now avoid the term "home equity loan" and use "HELOC" to refer to any
mortgage loan structured as a line of credit. While most of these loans
are second mortgages, some are first mortgages. If you own your house
free and clear and you want a line of credit secured by a mortgage, that
loan is a HELOC, even though it is a first mortgage. Similarly, if you
use a HELOC to refinance your first mortgage, the HELOC becomes a first
mortgage.
I avoid "home equity loan" because the term is now used to mean many
different things. Some people in the marketplace use it as a synonym for
second mortgage, while others use it as a synonym for HELOC. Regulators
usually define it as a mortgage on a home that is used for some purpose
other than to purchase the home. And the National Home Equity Mortgage
Association defines it as a mortgage to a subprime borrower!
In terms of usage, a HELOC is most convenient when your cash needs are
stretched out over time. A common example is a series of home
improvements, one followed by another. College tuition payments is
another.
Fixed-dollar seconds are best when you need all the money at one time.
Many home purchasers take out such seconds to avoid mortgage insurance
on the first mortgage.
When taking a fixed-dollar second, borrowers can select between fixed
and adjustable rates, as they prefer. When taking a HELOC, they take an
adjustable because all HELOCs are adjustable. However, some can be
converted into a fixed-dollar second at the market rate prevailing on
the second at the time.
