Is a Home Equity Loan a Good Idea? 5 Tests

Is a home equity loan a good idea? It is when you have a defined, one-off cost and can comfortably repay a fixed schedule. It is a poor idea when the payments would strain your budget, because your home is the collateral and, as the Consumer Financial Protection Bureau says, the lender could foreclose if you cannot repay.

The answer depends on your numbers, so this guide gives you five tests, a payment stress example, a comparison with a home equity line of credit and the questions to settle before you borrow. It is general information, not personal advice.

What a home equity loan is

Home equity is the part of your home's value that you own outright: the value minus what you still owe on it. A home equity loan lets you borrow against that equity. According to the Consumer Financial Protection Bureau, the equity is the collateral, the money is paid out as a lump sum, and the loan usually has a fixed interest rate. Because it sits behind your first mortgage, people often call it a second mortgage.

Three features follow. You receive the whole amount at once, so it suits a cost with a known size. A fixed rate means the rate itself does not move. And because the home secures the loan, falling behind has consequences beyond a damaged credit record.

Is a home equity loan a good idea? When it tends to make sense

The situations where a home equity loan fits best share a pattern: the cost is known, one-off and worth the risk, and the repayment is already within your means. They are criteria to check against your own situation, not recommendations.

• The amount is defined. A lump sum suits a single cost whose size you can estimate, rather than spending that arrives in stages.
• The payment fits with room to spare. Lenders commonly look for a debt-to-income ratio below 43%, according to LendingTree, but a lender's limit is not the same as your comfortable limit.
• You have a real equity cushion. LendingTree says lenders typically want at least 15% equity left in the home and cap combined borrowing at 80% to 85% of its value.
• A fixed schedule is an advantage. A fixed rate lets you plan the payment from the first month to the last.

To see what a particular amount would cost, put it through our home equity loan calculator, which shows the payment on a fixed lump sum over a term you choose.

When it is usually a bad idea

The same features that make a home equity loan attractive can make it a bad choice in other circumstances. The common thread is risk to the home.

• The payment is tight today. If the payment only just fits, a small drop in income turns a manageable loan into a problem. The CFPB's warning is blunt: if you cannot pay back the loan, the lender could foreclose on your home.
• The purpose has no lasting value. Borrowing against your home for spending that leaves nothing behind keeps the debt long after the benefit has gone. This is a judgement, not a rule, and only you can weigh it.
• Your equity is thin. With little equity, you are unlikely to meet the 80% to 85% combined cap, and a small fall in value would leave you with less cushion.
• Your income is uncertain. A fixed payment is predictable only if the income that pays it is.

Foreclosure is the legal process by which a lender can take a home to recover an unpaid secured loan. It is the reason this decision deserves more scrutiny than borrowing that is not secured by your house.

The five-test checklist

The checklist below turns the sources into five questions. Three of them (payment, equity and score) use limits LendingTree reports as typical. The other two are general good practice. A "pass" on every row does not guarantee approval or that borrowing is wise, and a single red flag is a reason to slow down.

We do not repeat the score tables here; our companion guide on getting a home equity loan with bad credit covers score floors in detail. The test with the most room for you to act is usually the payment, which is where the stress test comes in.

The tests applied to two fictional borrowers

Numbers make the tests concrete. Both borrowers below are invented, and the figures are illustrations, not advice or a prediction of what any lender would do.

Borrower A has a home worth $400,000 with a $250,000 mortgage and wants $40,000 for a defined, one-off cost. Combined borrowing would be $290,000, or 72.5% of the home's value, inside an 80% to 85% cap and leaving more than 15% equity. At an assumed 8% over 10 years the payment is about $485 a month. With $6,000 monthly income and $1,800 of existing debt payments, the debt-to-income ratio moves from 30% to about 38%, under the 43% level. On these tests Borrower A passes, though the resilience question still needs an honest answer.

Borrower B has a home worth $300,000 with a $240,000 mortgage and wants $30,000. Combined borrowing would be $270,000, or 90%, above the cap lenders cite, so the loan would likely be refused or reduced however good the credit score. The fix is not a cleverer application. It is waiting while the mortgage balance falls or the home's value rises, or borrowing a smaller amount.

A payment stress test

A good way to judge whether you can carry a loan is to see how much the payment changes if the rate is a point higher than you expected. The table is an illustration. The rates are assumptions chosen as inputs, not offers or market data, and the payments use the standard amortisation formula for a fixed-rate loan with equal monthly payments.

Two things stand out. First, a one-point difference in rate adds only about $16 to $43 a month on these loans, so the rate matters less than the amount and the term. Second, stretching the same $50,000 from 10 to 15 years lowers the payment by roughly $129 a month, but lengthens the time the loan is secured against your home. A smaller monthly payment is not the same as a cheaper loan.

Use the table the other way round as well. Take the payment you would be borrowing, add it to your existing monthly commitments, and ask whether you would still be comfortable if the household budget had to absorb an unexpected cost. If the honest answer is no, the loan is probably too large or too long.

Home equity loan or HELOC?

Many borrowers compare a home equity loan with a home equity line of credit before deciding. The two are both secured by the home but behave differently, as the CFPB's descriptions show.

The CFPB adds that during a HELOC's repayment period payments are often significantly higher than during the draw period, which is worth planning for. Our guide to HELOC versus home equity loan goes through the trade-offs. Other options you may weigh include a cash-out refinance or a personal loan, each with its own costs and risks that need separate comparison.

Tax note

Rules on whether the interest is deductible depend on how the money is used and on tax law that changes over time, so we do not state a rule here. Our page on whether HELOC interest is tax deductible explains the topic, and the Internal Revenue Service is the authority to check before you rely on any deduction.

Questions to settle before you borrow

• What is the exact cost I am borrowing for, and is it worth putting my home at risk?
• Does the payment still fit if my income falls for several months?
• How much equity will I have left after the loan?
• Would a smaller amount, or a different product, solve the problem?
• What fees and total repayment does the lender quote, in writing?

If the answers hold up, enter your own amount and term in the calculator linked above before you apply anywhere.
