# What Is a HELOC Loan? How It Works, Costs, and When Selling Makes More Sense By Opendoor Editorial Team | 2026-06-15 title: "What Is a HELOC Loan? How It Works, Costs, and When Selling Makes More Sense" slug: what-is-a-heloc-loan primary\_keyword: what is a heloc loan publish\_date: 2026-07-15 # What Is a HELOC Loan? How It Works, Costs, and When Selling Makes More Sense A HELOC — home equity line of credit — lets you borrow against the equity you've built in your home, drawing funds as needed up to an approved limit, much like a credit card. Unlike a traditional loan that pays out a lump sum, a HELOC gives you a revolving credit line with a variable interest rate, and you pay interest only on what you actually use. If you've been asking what is a HELOC loan and whether it's the right way to access [your home's value](https://www.opendoor.com/home-value-estimator), this guide covers how HELOCs work, what they cost, how they compare to other loan types, and when selling your home for cash is a stronger financial move than borrowing against it. ## Key Takeaways - A HELOC is a revolving line of credit secured by your home's equity, with a draw period (standard: 10 years) followed by a repayment period (standard: 20 years) (CU SoCal). - Lenders calculate your HELOC limit as 80–85% of your home's appraised value minus your outstanding mortgage balance (Comerica). - Borrowers need at least 15–20% home equity, a credit score of 680 or higher, and a debt-to-income ratio below 43% to qualify (CU SoCal). - HELOC interest is tax deductible only when the funds are used to buy, build, or substantially improve the home securing the line — a restriction set by the 2017 Tax Cuts and Jobs Act (IRS Publication 936). - If you sell your home while a HELOC is open, the outstanding balance is paid off from your sale proceeds at closing — reducing your net payout (Bank of America). ## What Is a HELOC Loan? A HELOC (home equity line of credit) is a revolving credit line secured by your home that lets you borrow, repay, and borrow again during an approved draw period — functioning more like a credit card than a closed-end loan. The [Consumer Financial Protection Bureau](https://www.consumerfinance.gov/ask-cfpb/what-is-the-difference-between-a-home-equity-loan-and-a-home-equity-line-of-credit-heloc-en-247/) draws a clear distinction: a home equity loan delivers a single lump sum at a fixed rate, while a HELOC gives you flexible access to funds at a variable rate. The term "HELOC loan" is common in everyday conversation, but it's technically redundant — HELOC already contains the word "credit." What matters more than the label is understanding the mechanics: your home serves as collateral, your equity determines how much you can borrow, and your interest rate moves with the market. To [find out what your home is worth](https://www.opendoor.com/articles/whats-your-home-worth-take-these-steps-to-find-out) — and therefore how much equity you have available — start with your remaining mortgage balance subtracted from your home's current [fair market value](https://www.opendoor.com/articles/fair-market-value-of-a-home-what-it-means-and-how-to-find-it). ## How Does a HELOC Work? You apply through a bank, credit union, or online lender; get approved for a credit limit based on your home's equity; then draw funds as needed during a set draw period and repay during a separate repayment period. You pay interest only on the amount you borrow, not the full credit line ([Bank of America](https://www.bankofamerica.com/mortgage/learn/what-is-a-home-equity-line-of-credit/)). ### How your credit limit is calculated Lenders set your maximum borrowing limit using this formula: your home's appraised value × 80–85%, minus your outstanding mortgage balance ([Comerica](https://www.comerica.com/insights/personal/home-ownership/how-does-a-heloc-work.html)). **Example:** Your home appraises at $400,000 and you owe $220,000 on your mortgage. At 80%, the lender allows $320,000 in total borrowing. Subtract the $220,000 mortgage and your HELOC limit is $100,000. Because the limit depends on an accurate appraisal, understanding [what appraisers look for](https://www.opendoor.com/articles/home-appraisal-tips-and-what-is-home-appraisal-based-on) — comparable sales, condition, square footage — directly affects how much equity you can access. If you're unsure whether your assessed value matches market reality, start with a [home value estimate](https://www.opendoor.com/articles/how-much-is-my-house-worth-7-ways-to-find-out-your-homes-value) before applying. ### Draw period vs. repayment period A standard HELOC has two distinct phases totaling roughly 30 years ([CU SoCal](https://www.cusocal.org/resources/blog/what-is-a-heloc-and-how-does-it-work/)): - **Draw period (10 years):** You can access funds, make interest-only payments, and re-borrow repaid amounts — similar to how a credit card balance revolves. - **Repayment period (20 years):** The line closes. You can no longer draw funds. Monthly payments now include principal and interest, which means they increase — sometimes significantly. This two-phase structure is the biggest difference between a HELOC and a [standard mortgage](https://www.opendoor.com/articles/what-is-a-mortgage-and-how-does-it-work). During the draw period, your payments stay low because you're covering interest only. Once repayment begins, the jump in payment size catches some borrowers off guard. ### Variable rates and fixed-rate conversion options HELOC rates are variable, calculated as the prime rate plus a margin set by the lender — for example, prime + 1.5% ([CU SoCal](https://www.cusocal.org/resources/blog/what-is-a-heloc-and-how-does-it-work/)). Because the prime rate tracks the [federal funds rate](https://www.federalreserve.gov/monetarypolicy/openmarket.htm), your HELOC rate rises and falls with Federal Reserve decisions. Understanding [how mortgage rates work](https://www.opendoor.com/articles/how-mortgage-rates-work) helps you anticipate these shifts. Some lenders offer a fixed-rate conversion feature that lets you lock a portion of your outstanding balance at a fixed rate, shielding that portion from future increases ([Comerica](https://www.comerica.com/insights/personal/home-ownership/how-does-a-heloc-work.html)). This hybrid approach gives flexibility on the undrawn portion while adding predictability on large, committed balances. ## What Can You Use a HELOC For? Home renovations, debt consolidation, education expenses, and emergency reserves are the four most common uses. Because a HELOC is secured by your home and carries lower rates than unsecured debt, homeowners use it to replace higher-interest credit card balances or fund projects that [increase home equity](https://www.opendoor.com/articles/briefs/how-to-increase-home-equity) — like a kitchen remodel or a [new roof](https://www.opendoor.com/articles/does-a-new-roof-increase-home-value-roi-costs-and-what-sellers-need-to-know). One important restriction: HELOC interest is tax deductible only when you use the funds to buy, build, or substantially improve the home that secures the line ([IRS Publication 936](https://www.irs.gov/publications/p936)). If you use HELOC funds to pay off credit cards or cover tuition, the interest on those draws is not deductible. This distinction matters when calculating the true cost of your borrowing plan. ## HELOC Requirements, Costs, and Tax Rules Qualifying for a HELOC requires at least 15–20% equity in your home, a credit score of 680 or higher, and a debt-to-income (DTI) ratio below 43% ([CU SoCal](https://www.cusocal.org/resources/blog/what-is-a-heloc-and-how-does-it-work/)). Lenders also review income documentation and employment history — the same factors they weigh for a [primary mortgage](https://www.opendoor.com/articles/what-is-a-mortgage-and-how-does-it-work). ### Closing costs and ongoing fees HELOC closing costs run 2–5% of the credit line ([Bank of America](https://www.bankofamerica.com/mortgage/learn/what-is-a-home-equity-line-of-credit/)). On a $100,000 line, that's $2,000–$5,000 in appraisal fees, title search, origination charges, and recording fees. Some lenders waive closing costs during promotional periods but add an early-termination fee — often $300–$500 — if you close the line within the first two to three years. Annual maintenance fees of $50–$100 are common as well. ### Current rate environment HELOC rates are tied to the prime rate, which tracks the federal funds rate. The Federal Reserve held the federal funds rate at 4.25–4.50% through its June 2025 meeting ([Federal Reserve](https://www.federalreserve.gov/monetarypolicy/openmarket.htm)). With the prime rate at 7.50% during that period, average HELOC rates ranged from roughly 7.75% to 10.50% depending on creditworthiness and lender margin ([Bankrate](https://www.bankrate.com/home-equity/heloc-rates/)). ### Sample payment calculation On a $50,000 HELOC at 8.5% variable, the interest-only payment during the draw period is approximately **$354 per month** ($50,000 × 0.085 ÷ 12). Once the repayment period begins and principal is added, that payment rises — the exact amount depends on the remaining balance and the rate at the time of conversion. ### Tax deductibility rules under TCJA The 2017 Tax Cuts and Jobs Act narrowed the deduction for home equity interest. HELOC interest is deductible only when the borrowed funds are used to buy, build, or substantially improve the property securing the line ([IRS Publication 936](https://www.irs.gov/publications/p936)). Funds used for any other purpose — debt consolidation, medical expenses, education — do not qualify. Keep records of how you spend HELOC draws so you can support the deduction if the IRS reviews your return. ## HELOC vs. Home Equity Loan vs. Personal Loan vs. Bridge Loan | Feature | HELOC | Home Equity Loan | Personal Loan | Bridge Loan | | --- | --- | --- | --- | --- | | Structure | Revolving credit line | Lump sum, closed-end | Lump sum, unsecured | Short-term lump sum, secured | | Rate type | Variable (some offer partial fixed-rate lock) | Fixed | Fixed or variable | Fixed or variable | | Collateral | Your home | Your home | None | Your current home (and sometimes the new one) | | Draw period | 10 years standard | None — full amount disbursed at closing | None — full amount disbursed at closing | None — full amount disbursed; term is 6–12 months | | Interest deductible? | Only if used to buy/build/improve the home ([IRS Pub. 936](https://www.irs.gov/publications/p936)) | Same rule as HELOC | No | No | | Best for | Ongoing or variable expenses (renovations, reserves) | One-time large expense at a known cost | Borrowers who don't want to risk their home as collateral | Homeowners [buying and selling at the same time](https://www.opendoor.com/articles/buying-and-selling-at-the-same-time-heres-how-to-prepare) who need short-term liquidity | | Risk if you default | Foreclosure | Foreclosure | Credit damage, collections — no home loss | Foreclosure | The core trade-off: a HELOC and home equity loan offer lower rates because your home is collateral, but both put your home at risk if you can't repay. A personal loan carries higher rates but doesn't touch your property. A bridge loan solves a narrow timing gap — useful when you're [selling and buying at the same time](https://www.opendoor.com/articles/how-to-sell-and-buy-a-house-at-the-same-time) — but comes with high origination fees and a compressed repayment window. ## When a HELOC Makes Sense — and When Selling Does A HELOC is the right tool when you need flexible, lower-cost access to cash and plan to stay in your home long enough to repay the balance. Selling is the stronger move when you have significant equity, want to eliminate debt rather than add it, or need to relocate. ### Signs a HELOC is the right choice - You plan to stay in your home for five or more years, giving you time to draw, use, and repay without the pressure of a looming sale. - You have a targeted renovation — kitchen, roof, bathroom — that will [increase your home's value](https://www.opendoor.com/articles/briefs/how-to-increase-home-equity) and that you can fund in stages during the draw period. - Your income comfortably supports the interest-only payments now and the higher principal-plus-interest payments that start when the repayment period begins. - You have a clear repayment plan. Without one, the revolving nature of a HELOC makes it easy to carry a growing balance into the repayment phase. ### Signs selling makes more sense - You're planning to relocate within the next one to two years. Opening a HELOC and then paying it off at closing adds costs — origination fees, appraisal fees, and possible early-termination penalties — that eat into your net proceeds. - You have substantial equity and want to convert it to cash without adding debt. A [cash offer on a house](https://www.opendoor.com/articles/what-is-a-cash-offer-in-real-estate-and-why-consider-it) turns that equity into liquid funds without a monthly payment obligation. - Your home's value has grown significantly and you want to capture those gains before market conditions shift. Understanding [how much it costs to sell a house](https://www.opendoor.com/articles/how-much-does-it-cost-to-sell-a-house) helps you compare the net proceeds from a sale against the net cost of a HELOC over time. - You want simplicity. A HELOC adds a second lien, a second set of monthly payments, and a variable rate that can increase with each Federal Reserve adjustment. Selling removes all of that complexity. ### What happens to your HELOC when you sell When you sell a home with an open HELOC, the outstanding balance is paid from your sale proceeds at closing — just like your primary mortgage ([Bank of America](https://www.bankofamerica.com/mortgage/learn/what-is-a-home-equity-line-of-credit/)). The title company distributes funds in this order: first mortgage payoff, then HELOC payoff, then [closing costs](https://www.opendoor.com/articles/how-to-read-a-closing-disclosure-what-to-look-for), then your net check. If your HELOC balance is large relative to your equity, the payoff can substantially reduce — or eliminate — your take-home proceeds. Before opening a HELOC, run the numbers on what you'd net from a sale today versus what you'd net after borrowing and repaying over time. A HELOC is not the right tool if you're planning to sell within one to two years — between closing costs on the HELOC and the payoff at sale, the net cost can exceed what you'd save by skipping the line entirely and selling directly. Sellers in that window are better served by a straightforward sale that converts equity to cash without adding debt. Opendoor is not the right fit if you have a home with extensive custom upgrades that drive value beyond what comparable sales reflect, or if you're in a position to wait 90+ days and manage showings in exchange for maximizing every dollar on the open market. But for homeowners who want certainty and speed — a cash offer in 24 hours, a [closing timeline you choose](https://www.opendoor.com/articles/how-long-does-closing-take), and no second lien on the property — requesting an offer takes minutes and comes with no obligation. Since 2014, Opendoor has bought 100,000+ homes because the model works on volume: a 5% service fee, no hidden costs, and 98% of offers close on time. ## Top Questions People Ask About HELOCs ### Is a HELOC a good idea right now? It depends on your timeline and purpose. With the federal funds rate at 4.25–4.50% as of the Fed's June 2025 meeting ([Federal Reserve](https://www.federalreserve.gov/monetarypolicy/openmarket.htm)), HELOC rates remain elevated compared to 2020–2021 levels. A HELOC still makes sense for homeowners with strong equity who need flexible access to cash for home improvements — especially improvements that increase [appraised value](https://www.opendoor.com/articles/market-value-vs-appraised-value-how-they-differ-and-when-each-one-matters). For homeowners considering a HELOC solely to access equity they plan to spend down without a clear repayment path, selling and capturing that equity as cash is a more straightforward option. ### What is the monthly payment on a $50,000 HELOC? At an 8.5% variable rate, the interest-only payment during the draw period is approximately $354 per month ($50,000 × 0.085 ÷ 12). During the repayment period, when principal payments begin, the monthly amount increases. The exact repayment-period payment depends on the balance and rate at conversion — if $50,000 remains at 8.5% over 20 years, the monthly payment rises to roughly $434. ### Is it better to refinance or get a HELOC? A cash-out refinance replaces your entire mortgage with a new, larger loan at a single rate. A HELOC adds a second lien and lets you borrow only what you need. Refinancing makes sense if current rates are lower than your existing mortgage rate and you want one predictable payment. A HELOC makes sense when your first mortgage already has a low rate you don't want to lose and you need flexible access to a smaller amount. ### Can your lender freeze or reduce your HELOC? Yes. If your home's value drops or your credit profile deteriorates, the lender can reduce your credit limit or freeze the line entirely ([Comerica](https://www.comerica.com/insights/personal/home-ownership/how-does-a-heloc-work.html)). This means your access to funds is not guaranteed for the life of the draw period. A significant local market downturn — or a missed payment on another account — can trigger a review. ### Do you need an appraisal to get a HELOC? In most cases, yes. The lender needs to confirm your home's current value to calculate your equity and credit limit. Some lenders accept an automated valuation model (AVM) for lower loan-to-value requests, but a full [home appraisal](https://www.opendoor.com/articles/home-appraisal-guide-what-it-is-how-long-it-takes-what-to-expect) — conducted in person by a licensed appraiser — is the standard requirement. Expect the appraisal to take one to two weeks to schedule and three to seven days for the report. ### How long does it take to get a HELOC? From application to funding, a HELOC takes two to six weeks. The timeline includes document submission, credit review, home appraisal, title search, and closing. Delays happen when appraisals take longer than expected or when documentation is incomplete. Having your income verification, tax returns, and mortgage statements ready at application shortens the process. ### What happens to my HELOC if my home value drops? Your lender can reduce or freeze the line ([CU SoCal](https://www.cusocal.org/resources/blog/what-is-a-heloc-and-how-does-it-work/)). If you've already drawn funds, you still owe that balance — a lower home value doesn't reduce what you've borrowed. In a steep decline, you can end up owing more on your combined mortgage and HELOC than your home is worth, which limits your ability to sell or refinance without bringing cash to the closing table. ### When does it make more sense to sell instead of opening a HELOC? Selling is the stronger choice when you're relocating within one to two years, when you want to convert equity to cash without monthly repayment obligations, or when your equity is high enough that the net sale proceeds exceed what you'd gain from a HELOC after accounting for interest, fees, and the payoff at sale. If you're weighing both paths, [request a cash offer](https://www.opendoor.com/articles/what-is-a-cash-offer-in-real-estate-and-why-consider-it) to see your actual number — then compare it to a HELOC scenario. **Frequently asked questions** --- *Originally published at [https://www.opendoor.com/articles/what-is-a-heloc-loan](https://www.opendoor.com/articles/what-is-a-heloc-loan)*
