Yes, credit unions offer home equity lines of credit, and a credit union home equity line of credit often costs less than the equivalent product at a bank. Because credit unions return earnings to members instead of shareholders, the savings tend to show up as smaller margins on the variable rate, waived or reduced closing costs, and fewer recurring fees. The trade-offs are real too: you have to join the credit union before you can apply, and the home securing the line is genuine collateral.
You Have to Join Before You Can Borrow
Every federal credit union is required to define a “field of membership” — a group tied together by an employer, a geographic area, or an organizational affiliation.1eCFR. Appendix B to Part 701, Title 12 – Chartering and Field of Membership Manual If you fit one of those categories, you can join by opening a share account with a small deposit. Federal law requires each member to subscribe to at least one share and pay the initial installment, but the dollar amount is set by each credit union’s board, not a federal rule.2Office of the Law Revision Counsel. 12 USC Chapter 14 – Federal Credit Unions In practice it usually falls between five and twenty-five dollars. Once that account is open, you’re a member-owner and can apply for a HELOC like any other lending product.
What It Takes to Qualify
Approval depends on four things: how much equity you have, your credit score, your debt load relative to income, and the type of property.
Equity and Combined Loan-to-Value
The combined loan-to-value ratio measures all mortgage debt on the home — including the new line — against the home’s appraised value. Most credit unions cap this at 80% to 90%, and a few go higher. More equity means a larger available line and a better rate.
Credit Score and Debt-to-Income
A score around 680 is a common minimum. Scores above 740 or 750 unlock the best pricing. Credit unions also look at debt-to-income — your total monthly debt payments divided by gross monthly income. At or below 43% is a comfortable range, though some will go higher when the rest of the application is strong.
Property Type
Primary residences and second homes are the standard. Some credit unions will lend against investment properties at lower CLTV limits and higher rates. Manufactured homes are frequently excluded.
How the Rate Is Built
Nearly every HELOC carries a variable rate made of two parts: an index, almost always the prime rate, and a margin the lender adds on top. The margin is fixed for the life of the line; the index moves with the economy. If prime is 6.50% and your margin is 2%, your rate is 8.50%. When prime rises a quarter point, so does your rate.
This is where credit unions tend to beat banks. Without shareholders to pay, their margins often run a half-point to a full point lower. On a five- or six-figure balance over a ten-year draw period, that difference adds up.
Federal regulations require every HELOC to disclose a maximum annual percentage rate — a lifetime cap your rate can never exceed, no matter where prime goes.3eCFR. 12 CFR 1026.40 – Requirements for Home Equity Plans Ask for that number before you sign; it’s your worst-case budget scenario, and it varies a lot from lender to lender. Some credit unions also offer a fixed-rate conversion feature, letting you lock part of your balance at a fixed rate during the draw period.
What You’ll Need to Apply
Gathering documents up front shortens the process:
- Income verification: recent pay stubs covering the last 30 days and W-2s from the previous two years. If you’re self-employed, bring federal tax returns and profit-and-loss documentation instead.
- Current mortgage statement showing your balance and payment history.
- Recent property tax assessment and your homeowners insurance declarations page.
- Government-issued ID and Social Security number for each applicant.
Make sure income figures match your tax documents exactly. Small mismatches flag the file for manual review and can add weeks. Use the same version of your property address across all documents too. Your insurance policy will need to list the credit union (or its servicer) in the mortgagee clause; if yours doesn’t, your insurer can add it before closing.
How Long Funding Takes
From application to funded line, expect two to six weeks. The biggest variable is the property valuation. An automated model can return a result in days; a full appraisal with an on-site visit and comparable research can take two weeks on its own.
After you sign closing documents, federal law gives you a three-business-day right of rescission on any credit line secured by your home.4eCFR. 12 CFR 1026.15 – Right of Rescission You can cancel for any reason during that window without owing anything. No money is disbursed until it closes.
Closing Costs and Ongoing Fees
HELOC closing costs typically run 2% to 5% of the credit line and cover appraisal, title search, recording, and any origination charge. Many credit unions absorb some or all of these costs. No-closing-cost HELOCs — where the institution picks up appraisal, title, and recording fees — are common at credit unions and much less so at large banks.
Three recurring charges are worth asking about before you commit:5Consumer Financial Protection Bureau. What Fees Can My Lender Charge if I Take Out a HELOC? an annual maintenance fee just for keeping the line open, an inactivity fee if you don’t draw within a set period, and an early termination fee if you close the line within the first two or three years. The early closure charge is often a flat few hundred dollars or a percentage of the outstanding balance.
The Draw Period and the Payment Jump
A HELOC has two phases. The draw period, usually five to ten years, is when you can pull funds up to your limit through checks, transfers, or a dedicated card. Most credit unions require only interest payments on what you’ve actually borrowed during this phase, which keeps costs low but doesn’t reduce the principal.
When the draw period ends, the line closes to new borrowing and a repayment period of roughly 20 years begins. Payments now include principal and interest, and they jump. Say you borrowed $60,000 at 8% and paid only interest — around $400 a month. Amortized over 20 years at the same rate, the payment climbs to roughly $500, and if the rate is still variable it can keep moving. Plan for that step up well before it arrives.
When the Interest Is Tax-Deductible
HELOC interest is deductible on your federal return only if you use the money to buy, build, or substantially improve the home securing the line.6Internal Revenue Service. Publication 936, Home Mortgage Interest Deduction A kitchen renovation or a new bathroom qualifies. Paying off credit cards, funding a vacation, or covering tuition does not, even though the funds come out of the same line. The IRS looks at how you spent the proceeds, not where the loan is secured.
There’s also a cap on total qualifying mortgage debt: interest on up to $750,000 in combined mortgage and HELOC balances for loans taken out after December 15, 2017 ($375,000 if married filing separately).6Internal Revenue Service. Publication 936, Home Mortgage Interest Deduction The One Big Beautiful Bill Act, signed in mid-2025, made that limit permanent. If your first mortgage is already near $750,000, a HELOC won’t add deductible interest regardless of how you spend it. Keep records of each draw and what it paid for; in an audit, you carry the burden of proving the money went to home improvement.
Risks Worth Taking Seriously
Your Home Is Collateral
A HELOC is a mortgage. If you stop paying, the credit union can foreclose to recover its money.7Federal Trade Commission. Home Equity Loans and Home Equity Lines of Credit That’s true at any balance. Because the access mechanics — checks, cards, online transfers — feel like a credit card, it’s easy to forget. The consequence of default is not the same.
The Credit Line Can Be Frozen or Reduced
Federal regulations let your lender suspend or shrink the available credit in specific circumstances: a significant drop in the home’s value below its original appraisal, a material change in your finances that calls repayment into question, default on a material term of the agreement, or government action affecting the lender’s security interest. When the triggering condition clears, the lender has to restore your credit privileges, but in the meantime you may lose access to funds you were counting on.
Variable Rate Exposure
In a rising-rate period, your payment goes up with every prime adjustment. On a $100,000 balance, each quarter-point increase adds roughly $20 to monthly interest cost. The lifetime cap sets the ceiling, but rates well below the cap can still strain a budget on a large balance. If predictability matters, ask about fixed-rate conversion before you finalize the line.
