A home equity line of credit (HELOC) is a revolving credit line secured by the equity in your home. It lets you borrow, repay, and borrow again up to an approved limit, typically at a lower rate than a credit card or personal loan. If you've owned your home for a few years, you may be sitting on more borrowing power than you realize, and a HELOC is one of the more misunderstood ways to access it.
The mechanics, and what happens once the draw period ends, trip up a lot of borrowers. This guide walks through how a HELOC works, what it can cost, and how it can fit into a broader plan to build your credit history.
What Is a HELOC?
A HELOC is a revolving line of credit secured by your home's equity. Unlike a personal loan or credit card, it's backed by real property, which typically means a lower interest rate, but also higher stakes if you miss payments: your home is the collateral.
Home equity is your home's current market value minus your remaining mortgage balance.
Example: if your home is worth $400,000 and you owe $250,000, you have $150,000 in equity. Most lenders let you borrow up to 85% of your home's value minus your mortgage balance.(b)
Because it's a secured loan, HELOCs typically offer more competitive rates than unsecured alternatives. The tradeoff is that defaulting could lead to foreclosure.
How Does a HELOC Work?
A HELOC works in two phases.
Draw Period (typically 5-10 years)
• Borrow funds up to your approved limit, repay, and borrow again, similar to a credit card
• Many lenders require only interest-only payments during this phase
• Monthly costs stay lower, but your principal doesn't shrink unless you pay extra
Repayment Period (typically 10-20 years)
• Withdrawals stop; you repay both principal and interest
• Payments can increase significantly compared to the draw period
• Budget adjustments are often necessary to avoid missed payments
Your credit limit is determined by your home equity, credit score, income, and debt-to-income (DTI) ratio, the share of your monthly income that goes toward debt payments.
A Real-World HELOC Example (Illustrative)
This is a composite example based on typical borrower scenarios and does not represent a specific individual.
Consider a homeowner named Marcus. His home is worth $380,000 and he owes $210,000 on his mortgage, giving him $170,000 in equity. His credit score is 688, and he wants to fund a $45,000 kitchen and bathroom renovation that will happen in two phases over 18 months.
Step 1: Calculate his borrowing limit.
Using the standard 85% LTV formula: ($380,000 x 0.85) - $210,000 = $113,000 available. His $45,000 goal is well within range, so he opens a HELOC with a $75,000 limit, keeping headroom for unexpected costs.
Step 2: Strategic draws during construction.
Marcus draws $22,000 in month one for the kitchen demo and materials, then another $23,000 in month nine when the bathroom phase begins. By drawing in stages, he only pays interest on what he's actually used, which keeps his monthly costs manageable.
Step 3: A rate increase mid-draw.
Eight months in, the prime rate rises by 1%. On his $22,000 balance, that adds roughly $18 a month, noticeable but not budget-breaking. Had his balance been $100,000, the same increase would add approximately $83 a month, a reminder to track rate changes closely.
Step 4: Building payment history.
Over 18 months of on-time HELOC payments, Marcus builds a consistent record. Payment history is the single largest factor in most credit scoring models,(a) so those on-time payments are the primary driver behind his stronger credit profile.
By the time Marcus enters the repayment period, his renovation has increased his home's value, and his credit profile is stronger for having made every payment on time.
What Can You Use a HELOC For?
HELOCs are flexible by design. Common uses include:
Home Improvements and Renovations
HELOCs are especially popular for multi-phase projects, since you draw funds as work progresses and pay interest only on what you use. Kitchen remodels, bathroom upgrades, solar panels, and outdoor living spaces can also increase your home's market value, indirectly building more equity over time.
According to the 2025 Cost vs. Value report, a minor midrange kitchen remodel recoups approximately 113% of its cost nationally at resale, making it one of the highest-ROI home improvements you can fund with a HELOC.(h)
Debt Consolidation
Paying off high-interest credit cards or personal loans with a lower-rate HELOC can reduce your monthly payments and total interest costs. Consolidating revolving debt can also lower your overall credit utilization ratio, a key factor in building your credit history.
As of mid-2026, average credit card APRs exceeded 20%,(f) while the national average HELOC rate was closer to 7.3%,(g) a gap of roughly 13 percentage points on every dollar you consolidate.
Important: consolidation only works if you commit to not running up new balances. Otherwise, you risk carrying both new debt and HELOC debt at the same time.
Emergency Expenses
A HELOC can act as a financial safety net for unexpected medical bills, major repairs, or urgent needs, without relying on costly payday loans or maxing out credit cards. Keeping your HELOC balance low also protects your credit utilization.
Education and Career Development
Some homeowners fund tuition or certifications through a HELOC, especially when the rate is lower than private student loans. This is a long-term financial commitment backed by your home, so it should align with a clear return on investment.
What Are the Key HELOC Terms You Need to Know?
• Draw Period: the initial borrowing phase (5-10 years). You access funds up to your limit, make minimum payments (often interest-only), and can reborrow repaid amounts throughout the draw period.
• Repayment Period: the phase after drawing ends (10-20 years). You pay both principal and interest, and monthly payments often rise substantially.
• Credit Limit: set by your lender based on your equity, credit score, income, and DTI ratio.(b)
• Credit Utilization: the percentage of your available HELOC limit you're using. High utilization can work against your credit evaluation. Most credit scoring models treat utilization above 30% as a risk signal, and HELOC balances factor into this calculation alongside your other revolving accounts.
• Hard Inquiry: a credit check that happens when you apply for a HELOC. It causes a small, temporary dip in your score.
Fixed vs. Variable Interest Rates: Which Should You Choose?
Most HELOCs start with a variable rate tied to the U.S. prime rate or another market index. Some lenders let you lock in a fixed rate on part, or all, of your balance.
Variable Rates
• Start lower than fixed rates
• Payments fluctuate with market conditions
• Can strain your budget if rates rise significantly
• A 1% rise in the prime rate adds roughly $83 a month on a $100,000 HELOC balance, so budget accordingly
Example: a HELOC at 7% tied to the prime rate becomes 8% if the prime rate rises by 1%, and your payment rises accordingly.
Fixed Rates
• Predictable payments that don't change
• Generally higher than the initial variable rate
• Many lenders allow partial locks (for example, fix $20,000 at 8% while keeping $30,000 variable)
What Are the Requirements to Qualify for a HELOC?
Most lenders require:
• 15%-20% equity in your home
• A credit score of 620 or higher (higher scores tend to get better rates)
• A good payment history, with no recent major delinquencies
• A DTI ratio below 43%(c)
• Steady, verifiable income
Your credit score and credit report affect both your approval odds and your interest rate. The stronger your credit profile before you apply, the more favorable your terms are likely to be.
What Does a HELOC Cost?
Beyond interest, HELOCs can carry several fees:
• Application and origination fees
• Appraisal and title fees
• Closing costs
• Annual or membership fees
• Inactivity fees, if the credit line goes unused
• Early closure fees, if you cancel within the first few years
• Conversion fees, for switching to a fixed rate
Always compare multiple lenders. The lowest interest rate doesn't always mean the lowest total cost once fees are factored in.
What Are the Pros and Cons of a HELOC?
Pros
• Lower interest rates than unsecured loans or credit cards
• Flexible, on-demand access to funds during the draw period
• An interest-only payment option keeps initial costs manageable
• Can improve your credit utilization if used to consolidate revolving debt
Cons
• Variable rates can increase monthly payments unpredictably
• Your home is at risk if you miss payments
• Fees add to the true cost of borrowing
• Lenders can reduce or freeze your credit line if home values drop(e)
How Does a HELOC Affect Your Credit Profile?
Credit Factor
HELOC Impact
Payment History
On-time payments strengthen your credit history; missed payments can stay on your report for up to 7 years(d)
Credit Utilization
A high HELOC balance relative to your limit can raise utilization and work against your score(a)
Hard Inquiry
Applying triggers a small, temporary score dip (typically 2-5 points)
Account Age
Opening a new HELOC slightly lowers your average account age
Key takeaway: The most controllable factor is paying on time, every time. Missed HELOC payments can stay on your credit report for up to seven years.(d)
Best Practices for Managing a HELOC
• Keep utilization below 30% of your credit limit; most credit scoring models flag usage above this threshold as a risk signal
• Pay more than the minimum during the draw period to reduce principal
• Track rate changes closely if you have a variable rate; a 1% prime rate increase adds roughly $83 a month on a $100,000 balance
• Budget ahead for the repayment period, when payments will likely increase
• Combine a HELOC with credit-building tools to maintain or build your credit history at the same time
How Can You Build Credit While Managing a HELOC?
A HELOC can support your overall credit health when you manage it responsibly, but it isn't a standalone credit-building tool on its own. If you're also working to build your credit history, tools like Ava can work alongside your existing HELOC and other financial habits.
Ava reports your rent and utility payments to TransUnion, and reports your Ava credit products to all three major credit bureaus.(8) Your credit score may increase or decrease, and Ava cannot guarantee results. Membership fees apply.(10) There's no hard credit check to start rent and utility reporting, no interest charged on the bills you report, and no need to take on new debt to participate. If you're using a HELOC for home improvements or debt consolidation while also building your credit history, pairing responsible HELOC use with Ava's reporting features can create separate, positive payment history streams on your credit report.
Frequently Asked Questions About HELOCs
What is the difference between a HELOC and a home equity loan?
A HELOC is a revolving credit line with a variable rate: you borrow as needed up to your limit. A home equity loan provides a lump sum at a fixed rate. HELOCs tend to work better for ongoing expenses; home equity loans tend to work better for one-time fixed costs.
Can you get a HELOC with bad credit?
It's difficult. Most lenders require a credit score of at least 620, and scores below that typically lead to denial or much higher rates. Improving your credit profile before you apply, through on-time payments, lower utilization, and credit-building tools like Ava, may help you qualify for better terms.
Does a HELOC hurt your credit score?
Applying for a HELOC triggers a hard inquiry, which causes a small, temporary dip. Once the line is open, how you manage it matters more: high utilization and missed payments can hurt your score, while consistent on-time payments strengthen your credit history.
What happens when the HELOC draw period ends?
You can no longer borrow against the line. You enter the repayment period and must pay both principal and interest. Monthly payments often increase significantly, so it's worth planning ahead.
Can a lender reduce or freeze your HELOC?
Yes. If your home's value drops significantly or your financial situation changes, your lender can reduce your credit limit or freeze access to funds, even during the draw period.(e)
Is a HELOC a good idea for debt consolidation?
It can be, if the HELOC rate is meaningfully lower than the debt you're consolidating and you commit to not adding new balances. With credit card APRs averaging over 20% and HELOC rates averaging closer to 7.3%,(f)(g) the savings can be substantial, but without spending discipline, this strategy can put your home at risk.
How does Ava compare to Self for building credit?
Ava and Self use different models, and the cost structure is meaningfully different. Self's credit-builder loan carries an APR of roughly 15.5% to 15.9% depending on the plan, plus a late fee of up to 5% of the scheduled payment if you pay 15 or more days late.(i) Ava Membership adds no new debt or interest charges to your budget, though membership fees apply.(10) Self is a credit-builder loan: you take on new debt, make monthly payments, and receive the saved principal at term end, minus fees and interest. Ava reports bills you're already paying, like rent and utilities, to TransUnion, and your Ava credit products to all three bureaus,(8) building positive payment history without new debt, interest, or a hard credit inquiry. If a forced-savings component or installment loan history is a specific goal, Self offers that structure, though it comes with fees, interest, and an added monthly obligation on your budget. For someone already managing a HELOC, Ava layers positive credit history from bills you're already paying, without added debt, interest, or a hard inquiry, keeping your financial footprint simple while you build credit history. Neither product requires a hard credit check to get started.
The Bottom Line
A HELOC tends to make the most sense when your equity exceeds 20%, your DTI is below 40%, and your planned use has a clear return, like a renovation that increases your home's value or paying off high-interest debt you're committed to not rebuilding. If you can answer yes to those three conditions, it's one of the lower-cost borrowing tools available to homeowners.
Combined with a credit-building strategy, like using Ava to report your rent and utility payments to TransUnion, a HELOC can be part of a broader plan to build your credit history over time.
