If you’re a homeowner, you have a powerful tool in your financial arsenal: the home equity loan.

Home equity loans allow some consumers to borrow a large amount of money relatively easily and cheaply. But they aren’t right for all situations. Here’s a bit more about how they work and when they’re a good option.

How home equity loans work

A home equity loan is a loan secured by the value of the borrower’s house. Sometimes called second mortgages, home equity loans come with favorable terms because they’re low risk for lenders. Toqualify for one, you’ll needsignificant equity in your home — that’s the difference between what yourhome is worth and what youowe on it. Lenders use a figure called loan-to-value ratio, or LTV, to help determine which loan applicants qualify. For example, if your house is worth $250,000 and your mortgage balance is $150,000, you have $100,000 in equity. Your LTV, which is the amountyou currently owe on the house divided by its current value, is 60%. The lower the LTV on your first mortgage, the easier it is to qualify for a second. Keep in mind that a home equity loan isdifferent from a home equity line of credit, also called a HELOC. Home equity loans are installment loans with fixed payments, like auto loans; HELOCs are revolving debt with variable payments, like credit cards.

Pros and cons

Home equity loans have a number of advantages over personal loans and some other kinds of debt:

• They typically have lower interest rates.
• They’re easier to qualify for, even if you have average credit.
• Interest payments are tax-deductible in most cases.
• They offer potentially high loan amounts, depending on the home equity available.

There are also some downsides to home equity loans:

• If you miss payments on your loan, the lender can foreclose on your home.
• If your home value drops, you could end up with high LTV or even “underwater” on your mortgage, owing more than thehome is worth. And if you were to sell your home, you would owe your lender the difference between the sale price and your mortgage at closing.

How to usea home equity loan

Because home equity loans can provide a large amount of money, borrowers tend to use them to pay major expenses, such as:

• College tuition.
• Large medical bills.
• Home improvements or major repairs.

Some home owners use home equity loans to consolidate higher-interest debt, such as credit card debt. However, that’s considered a risky move by consumer groups like the Consumer Financial Protection Bureau, since failing to make payments on a second mortgage can lead to foreclosure.
