HELOC vs. Home Equity Loan: Which Way of Borrowing Against Your House Is Less Painful

Once you have owned a home for a few years, you start getting mail about your equity like it is free money. Your house is worth more than you owe, and banks are happy to let you borrow against the difference. There are two main ways to do it: a home equity loan and a home equity line of credit, or HELOC. They sound similar, they use the same equity, and picking the wrong one for your situation can cost you thousands. The difference is simple: one is a lump sum with a fixed payment, the other is a credit line you draw from as you go.

A home equity loan works like a second mortgage. You borrow a set amount — say $40,000 — and the bank deposits it all at once. You pay it back over a fixed term, usually 5 to 30 years, at a fixed interest rate, with the same payment every month. You know exactly what you owe, what it costs, and when it is gone. That predictability is the whole appeal. If you are paying for something with a known price tag — a $35,000 roof, a $40,000 kitchen, consolidating $30,000 of high-interest debt — a home equity loan fits, because you know the number upfront and you want the payment to stay the same.

A HELOC works more like a credit card secured by your house. The bank approves you for a maximum — say $50,000 — and you draw from it when you need it, pay interest only on what you actually borrowed, and can borrow again as you pay it back. Most HELOCs have a draw period of about 10 years, then a repayment period of 10 to 20 years where you pay down the balance and cannot draw anymore. The catch is the rate: HELOCs are almost always variable, tied to the prime rate, so your payment moves up and down with the market. Borrow $20,000 at 7 percent and your payment is one thing; if the rate climbs to 9 percent, your payment climbs with it. That flexibility is great for costs that come in stages — a renovation that takes a year, college tuition paid semester by semester — and risky if you need a stable payment you can plan around.

The math that matters is not just the rate, it is the total cost and the timeline. A home equity loan at 8 percent fixed for 15 years on $40,000 costs about $382 a month and roughly $28,800 in total interest. A HELOC at 7.5 percent variable on the same $40,000 starts cheaper, but if rates rise a couple of points during the draw period, your interest cost climbs past the fixed loan fast — and during the draw period you might only be paying interest, which means the balance barely moves for a decade and then the repayment period hits with a much bigger payment. That jump catches people off guard. If your HELOC has a minimum draw or an annual fee, add those in too. Some HELOCs charge $50 to $75 a year just to keep the line open, and some charge a fee every time you draw.

Both options share the risk that makes people nervous, and it should: your house is the collateral. If you cannot make the payments, the lender can foreclose. That is the real difference between borrowing against your house and borrowing on a credit card. A credit card default wrecks your credit. A home equity default can cost you your home. That is why the reason for borrowing matters as much as the rate. Borrowing against equity to fix the roof, fund a renovation that adds value, or wipe out 24 percent credit card debt can be a smart trade. Borrowing against it for a vacation, a car, or a wedding is turning a long-term asset into short-term spending, and if the payments get tight later, you will wish you had not.

There are also tax wrinkles worth knowing. Interest on home equity borrowing is only tax-deductible if the money is used to buy, build, or substantially improve the home that secures the loan. Using a HELOC to pay off credit cards or buy a boat? The interest is not deductible. Using it to remodel the kitchen? It can be. The rules changed in 2018 and they are not as generous as they used to be, so do not count on a deduction unless the money goes into the house itself.

A few practical rules. Do not borrow the maximum just because the bank offers it. On a $300,000 home with a $200,000 mortgage, you have $100,000 of equity, and lenders will often let you borrow up to 80 or 85 percent of the home's value minus what you owe — around $40,000 to $55,000 in that example. Just because you can borrow $55,000 does not mean you should. Borrow the amount the project actually costs, not the amount the bank will approve. And keep an emergency fund separate. If you drain your equity for a renovation and then lose your job, you have no cushion and a new monthly payment at the same time.

So which one wins? If the cost is a fixed number and you want a fixed payment you can set and forget, take the home equity loan. If the costs are spread out over months or years and you only want to pay interest on what you actually use, take the HELOC — and make sure you can handle the payment if rates rise two points, because they might. Either way, you are putting your house on the line, so the purchase needs to be worth that. A new roof is. A vacation is not.
