HELOC pros
A HELOC's main advantage is flexibility: you open one line and borrow from it only when, and as much as, you need. The CFPB describes it as borrowing, spending and repaying as you go,[1] and interest accrues only on the amount drawn.
- Lower rates than most other credit. Because your home lowers the lender's risk, HELOC rates are generally lower than rates on other types of credit.[2]
- Low payments while you draw. Many plans require only interest during the draw period.[1] On $30,000 at 8.00% that is $200.00 a month.
- Reusable. Principal you repay during the draw period can be borrowed again without a new application.
- Possible tax deduction. Interest can be deductible when the money is used to buy, build or substantially improve the home that secures the line.[7]
HELOC cons
The main drawbacks all come from two features: a variable rate and a house as collateral.
- The rate can climb without a yearly limit. Supervisors note that HELOCs generally lack caps that limit rate increases.[3] The law requires only a lifetime maximum rate in the contract.[5]
- Payment shock. When the draw ends, principal comes due through higher monthly payments or, on some plans, a balloon.[4]
- The line can be frozen. If the home's value declines significantly or your finances change materially, the lender may stop draws or cut the limit, possibly just when you need the money.[6]
- Fees. Appraisal, application and closing costs up front, and possibly annual or per-draw fees; the APR does not include them.[2]
- Your home is at stake. If you cannot repay, or cannot pay a balloon, you could lose the house.[1]
| Feature | Pro | Con |
|---|---|---|
| Variable rate | Falls when prime falls | Rises when prime rises, often with no yearly cap |
| Interest-only draw | Low early payments | No principal repaid; payment jumps later |
| Revolving line | Borrow only what you need, reuse it | Easy to keep borrowing |
| Secured by your home | Lower rate than unsecured credit | Home at risk; line can be frozen |
| Tax treatment | Deductible when used on the home | Not deductible for other uses |
How rate rises change the payment
Each point of prime adds about $25.00 a month in interest on a $30,000 balance during the draw, and more once principal is due. The prime rate has moved from 3.25% at the start of 2022 to 7.00% on November 12, 2026.[8] The same $30,000 line at today's rate and after rises:
| Rate | Draw-period payment | Repayment payment | Total interest |
|---|---|---|---|
| 8.00% | $200.00 | $250.93 | $54,224 |
| 9.00% (+1) | $225.00 | $269.92 | $61,780 |
| 10.00% (+2) | $250.00 | $289.51 | $69,482 |
| 11.00% (+3) | $275.00 | $309.66 | $77,318 |
| 12.00% (+4) | $300.00 | $330.33 | $85,278 |
Is a HELOC a good idea? Five questions
A HELOC is a good idea when you need money in stages, can afford the payment after the draw period at a higher rate, and will keep plenty of equity. Answer these before you apply:
- Do you need a set amount once? The CFPB's booklet suggests a traditional second mortgage when you need a set amount for a specific purpose, such as an addition.[2] Compare both on the home equity loan vs. HELOC page.
- Can you pay the repayment payment at a higher rate? Lenders are expected to check whether you could repay the fully drawn line if rates rise;[3] do the same with the calculator above.
- Will you sell soon? The line usually has to be paid off at sale, and setup costs may not be worth it for a short stay.[2]
- What is the money for? Using it on the home can keep the interest deductible; see is HELOC interest tax deductible.
- How much cushion is left? Borrowing near 90–100% of the value leaves little room before the line can be frozen; see high LTV HELOC.
Worked example
A homeowner with a $500,000 house and a $260,000 mortgage wants $30,000 for repairs over the next year. Prime is 7.00% and the lender quotes a 1-point margin: 8.00%.
- Room under an 85% limit: $165,000, so the draw fits with a large cushion (CLTV 58%).
- Interest-only payment: $200.00. After 10 years, repaying over 20: $250.93.
- If prime is 3 points higher by then: $309.66. If that number fits the budget, the HELOC passes the stress test.

Frequently asked questions
Is a HELOC a good idea right now?
It depends less on the date than on your numbers. With prime at 7.00% on Nov 12, 2026, check the payment after the draw at a rate 2–3 points higher; if you can carry it and keep a healthy equity cushion, a HELOC can be a reasonable way to borrow.
What is the biggest disadvantage of a HELOC?
The variable rate on a loan secured by your home. Payments can rise with rates and again when the draw ends, and falling behind puts the home at risk.[1]
Is it better to get a HELOC or a home equity loan?
A HELOC suits costs that come in stages or an uncertain amount. A home equity loan suits a known, one-time cost and gives a fixed payment from the start.
Does a HELOC hurt your credit?
Opening one adds a credit inquiry and a new account, and a large balance raises your debt. Paying on time builds a positive history; missing payments damages it and risks the home.
