Introduction

A home equity line of credit is one of the cheapest ways to borrow money in 2026 — rates averaged 8% to 9%, far below credit cards near 24% — but it is also one of the hardest loans to qualify for. Because the line is secured by your house, lenders underwrite HELOCs like mortgages: they verify your equity, your credit, your income, and even how long you have owned the home.

This guide breaks down HELOC Requirements: Minimum Equity, Credit Score, and DTI with the specific thresholds lenders actually use in 2025–2026, so you know before you apply whether you will qualify — and what to fix if you will not.

Minimum Equity: 15–20% Retained, 80–85% CLTV Max

The single most important requirement is equity. Most lenders want you to retain 15% to 20% equity in the home after the line is opened, which means your combined loan-to-value (CLTV) — your first mortgage plus the HELOC divided by the home's value — can reach at most 80% to 85%. A borrower with a 700 credit score often qualifies for the full 85% CLTV; a borrower at 640 might be capped at 80%.

The math matters. On a $400,000 home, an 85% CLTV cap allows $340,000 of total debt. If your first mortgage has a $250,000 balance, your HELOC limit is $90,000. But if the home is worth $320,000 and you still owe $280,000, your CLTV is already 87.5% — you do not qualify at all until you pay down the mortgage or the home appreciates. Note that lenders count the full credit limit, not just what you draw, when they calculate CLTV.

Credit Score Minimums: 620–680

Credit score floors vary by lender type. The absolute minimum across most banks and credit unions is 620, but the typical approved HELOC borrower in 2026 has a score of 680 or higher, and the best rates go to scores of 720+. A score in the 620–679 band usually means a higher rate margin (prime plus 1.5 points instead of prime plus 0.5), a reduced maximum CLTV of 80%, and a smaller line — often capped at $50,000 to $100,000.

Your score also determines your rate tier more than any other single factor. The difference between a 640 and a 760 score in 2026 was roughly 0.75 to 1.25 percentage points on a HELOC — on a $50,000 balance, that is $375 to $625 a year. Before applying, check all three credit bureaus for errors: a single late payment incorrectly reported on one report can drop you below a lender's cutoff.

DTI Caps: 43–50%

Your debt-to-income ratio — total monthly debt payments divided by gross monthly income — is capped at 43% to 50% by most HELOC lenders, with 45% the most common cutoff. On $8,000 of gross monthly income, a 45% cap allows $3,600 of total monthly debt: mortgage, car loans, student loans, credit card minimums, and the HELOC payment combined.

Two details trip up applicants. First, lenders often qualify the HELOC payment on the full credit limit, not the amount you plan to draw — a $50,000 line at 8.5% amortized over 20 years counts as roughly $434 a month even if you borrow $10,000. Second, the front-end (housing-only) ratio is usually softer, but the back-end (all-debt) ratio is rarely flexible above 50%. If you are near the cap, pay off a car loan or credit card balance before applying rather than hoping for an exception.

Seasoning Requirements

Seasoning is the length of time you have owned the property or held your current mortgage, and lenders enforce it strictly. Most require the home to be owned for 6 to 12 months before you can open a HELOC; a few lenders allow it immediately if you bought with cash or put down a very large down payment. If you recently completed a cash-out refinance, most lenders also want that loan seasoned at least 6 months — a rule designed to stop borrowers from immediately re-leveraging.

Adverse-event seasoning is stricter. After a Chapter 7 bankruptcy, most lenders wait 2 to 4 years from discharge; after a Chapter 13, 1 to 2 years of on-time payments; and after a foreclosure or deed-in-lieu, 3 to 7 years (Fannie Mae requires 7, many portfolio lenders accept 3 to 4). A prior short sale typically needs 2 to 4 years. If you are within these windows, the application is a guaranteed decline — wait them out rather than burning a hard inquiry.

Income Verification

HELOCs are full-documentation loans, not stated-income products. W-2 employees provide two years of W-2s, the most recent 30 days of pay stubs, and consent to an employment verification call. Self-employed borrowers provide two years of personal and business tax returns, a year-to-date profit-and-loss statement, and often a CPA-prepared letter. Rental income counts only with a two-year history on tax returns.

Lenders also review two months of bank statements for all accounts, and they look hard at your first-mortgage payment history: most require the current mortgage to be paid on time for the last 12 months. One 30-day late in the past year can trigger a manual review or an additional 10% reduction in your line amount. Gather everything before applying — document requests that drag out past the rate-lock window can cost you the quoted margin.

Other Factors Lenders Check

Beyond the headline numbers, lenders evaluate the property itself. Most HELOCs are limited to owner-occupied primary residences and second homes; investment properties usually need a commercial-style line at a higher rate. The appraisal method matters too — many lenders use an automated valuation model for lines under $100,000, but a full appraisal for larger lines, and a low appraisal can shrink your line by tens of thousands of dollars.

You also cannot use gift funds to satisfy the equity test: the equity must be genuinely yours, built through down payment, principal paydown, or appreciation. And lenders pull your credit again at closing — a new car loan taken out between application and closing can kill an approval that was already granted.

How to Improve Your Chances

• Pay down the first mortgage to push CLTV under 80% — this is the single fastest fix
• Raise your score above 680: dispute errors, keep credit card balances under 30% of limits, and pay everything on time for six months
• Lower your DTI by paying off small debts before applying, since the HELOC payment is counted on the full limit
• Wait out seasoning windows rather than applying early and taking a denial on your record
• Prepare documents in advance: two years of returns, W-2s, statements, and mortgage history so the file closes fast

If you meet the 15–20% equity test, score above 680, and keep DTI under 45%, you are in the approval zone at most lenders in 2026. If you miss one requirement, fix it first — a HELOC denial is a hard inquiry that costs points and leaves a paper trail, so apply only when the checklist is fully checked.
