What Is HELOC (Home Equity Line of Credit)?
A HELOC is a revolving line of credit secured by your home that lets you borrow against your equity as needed. Unlike a home equity loan that provides a lump sum, a HELOC works like a credit card — you draw funds, repay, and borrow again during the draw period (typically 10 years). After the draw period, you enter a repayment period where you must pay down the balance.
Key Facts
- Total HELOC balances across U.S. households reached approximately $434 billion as of late 2025, rising steadily after years of post-2008 deleveraging — a signal the American Distress Index tracks through its Buffer Depletion component
- HELOCs typically carry variable interest rates tied to the prime rate plus a margin of 0.5-2.0% — when the Fed raises rates, HELOC payments increase immediately
- The draw period (typically 10 years) allows flexible borrowing, but the transition to the repayment period can cause payment shock — monthly payments can double or triple when principal repayment begins
- Most lenders allow combined loan-to-value (CLTV) up to 80-85%, meaning your first mortgage plus HELOC limit cannot exceed 80-85% of your home's appraised value
- HELOCs originated during the 2004-2006 housing boom reached their repayment periods around 2014-2016, contributing to a wave of defaults that extended the housing crisis aftermath

How Does a HELOC Work?
A HELOC has two distinct phases:
- Draw period (typically 10 years): You can borrow up to your credit limit, repay, and borrow again — similar to a credit card but secured by your home. During this period, many HELOCs require only interest payments (no principal), keeping monthly costs low.
- Repayment period (typically 10-20 years): You can no longer draw new funds. The outstanding balance converts to a fully amortizing loan with both principal and interest payments. This transition often causes significant payment shock.
The Payment Shock Problem
The transition from draw period to repayment period is the most dangerous moment in a HELOC's life. Consider a $100,000 HELOC at 8.5% interest:
- During draw period: Interest-only payment = $708/month
- During repayment period (15 years): Fully amortizing payment = $985/month
That's a 39% payment increase on the same balance — and if rates have risen since the draw period began, the shock is even larger. Borrowers who stretched to afford the interest-only draw period payments may be unable to handle the repayment period.
HELOC vs. Home Equity Loan
- HELOC: Variable rate, revolving credit, draw-as-needed, interest-only option during draw period. Best for: ongoing expenses, emergency access, uncertain funding needs.
- Home equity loan: Fixed rate, lump sum, predictable payments from day one. Best for: one-time large expenses, debt consolidation where you want payment certainty.
In a rising rate environment, fixed-rate home equity loans protect against rate increases. In a falling rate environment, variable-rate HELOCs become cheaper automatically.
HELOCs and Home Price Risk
HELOCs amplify the risk of falling home prices. If you have an 80% LTV first mortgage and a HELOC bringing your CLTV to 95%, even a modest 10% price decline puts you underwater. During the 2008 crisis, many homeowners who had drawn heavily on HELOCs found themselves owing far more than their homes were worth, with no ability to refinance or sell.
Additionally, if home values drop, lenders can freeze or reduce your HELOC — cutting off access to the credit line just when you might need it most. This happened to millions of homeowners during 2008-2010.
Why HELOCs Matter for Financial Distress
Rising HELOC balances are a direct measure of equity extraction — households converting their home equity buffer into consumable cash. The American Distress Index tracks HELOC balance growth as part of the Buffer Depletion component. When HELOC borrowing accelerates alongside declining savings rates and rising hardship withdrawals from retirement accounts, it signals households are depleting multiple financial reserves simultaneously — the pattern that preceded the 2008 crisis by approximately two years.
State-by-State Variations
HELOC regulations follow federal TILA requirements with some states adding additional protections, particularly around rate caps, minimum draw periods, and cooling-off periods.
| State | Key Difference |
|---|---|
| Texas | Uniquely restrictive: combined LTV capped at 80% for all home equity lending (Texas Constitution). HELOCs count toward this cap. 12-day waiting period, cannot close at borrower's home, minimum $4,000 advances. |
| New York | Mandatory 3-day right of rescission (federal TILA). Additional state disclosures required about variable rate risks and potential payment increases during the repayment period. |
| California | Anti-deficiency protections generally do NOT apply to HELOCs — they apply to purchase money mortgages. A lender can pursue a deficiency judgment on a defaulted HELOC even after foreclosure by the first mortgage holder. |
| Maryland | Maryland's mandatory mediation program covers HELOC defaults as well as first mortgage foreclosures, giving borrowers an opportunity to negotiate with the HELOC lender. |
| Georgia | Georgia's fast non-judicial foreclosure process (as quick as 37 days) applies to HELOC defaults, meaning a HELOC lender can foreclose rapidly if the first mortgage holder doesn't act first. |
Frequently Asked Questions
What is the difference between a HELOC and a home equity loan?
A HELOC is a revolving line of credit with a variable rate — you draw and repay like a credit card. A home equity loan is a lump-sum second mortgage with a fixed rate and fixed payments. HELOCs offer more flexibility; home equity loans offer more predictability. Both use your home as collateral.
What happens when my HELOC draw period ends?
Your HELOC converts to a repayment period (typically 10-20 years) where you can no longer draw funds and must begin paying both principal and interest. This transition often causes payment shock — your monthly payment can increase 30-50% or more. Contact your lender before the transition to discuss options.
Can my HELOC be frozen or reduced?
Yes. Lenders can freeze or reduce your credit line if your home's value drops significantly, your creditworthiness changes, or the lender has financial concerns. This happened to millions of borrowers during the 2008 crisis. A HELOC is not a guaranteed source of emergency funds.
Are HELOC payments tax-deductible?
Interest on a HELOC is deductible only if the funds are used to buy, build, or substantially improve the home that secures the loan. Using HELOC funds for debt consolidation, vacations, or other purposes does not qualify for the deduction under the Tax Cuts and Jobs Act of 2017.
Is a HELOC a good idea right now?
It depends on your financial situation and rate environment. HELOCs have variable rates tied to the prime rate — when rates are high or rising, HELOC costs increase. Consider whether you can handle higher payments, whether a fixed-rate home equity loan might be safer, and whether you truly need to borrow against your home.
