HELOC Requirements: What Lenders Check Before They Open a Line

By LoansGenerator.com · Last updated October 26, 2026

A home equity line of credit (HELOC) lets you borrow against the part of your home you own outright. Lenders decide whether to open one, and how large, from five things: how much equity you have, the combined loan-to-value ratio after the new line, your credit score, your debt-to-income ratio, and income you can document. This page sets out what named lenders publish for each one, checked October 26, 2026, and shows the math with a worked example. A HELOC is secured by your home. The CFPB puts it plainly: "If you fall behind or can't repay the loan on schedule, you could lose your home."

Key takeaways

• Equity is the first gate. Bank of America's HELOC explainer says you can "typically" borrow up to 85% of your home's value minus what you owe, and Freedom Mortgage says many lenders allow 80% to 85%. That limit is a combined loan-to-value (CLTV) ratio.
• Published credit score floors we found range from 640 (Freedom Mortgage) to 660 (U.S. Bank). Bank of America and Navy Federal publish no number on the pages we read.
• Lenders add an estimated HELOC payment to your existing debts before checking DTI. Rate says a typical lender maximum is 43% and allows its own borrowers under 50%; loanDepot calls 50% or less the standard goal.
• Expect to document income, the mortgage balance, homeowners insurance and the home's value (an appraisal or another valuation).
• Meeting a published rule does not mean a lender will approve you. Each lender sets its own criteria.

This page is part of our guide to home equity loans, HELOCs and refinancing.

What are the requirements for a HELOC?

The CFPB booklet on HELOCs describes the same pattern from the lender's side: many lenders set the line by taking a percentage of the home's appraised value and subtracting the balance owed on the existing mortgage, and they also look at your income, debts and credit history.

How much equity do you need for a HELOC?

Equity is your home's value minus what you owe on it. Lenders do not let you borrow all of it. They cap the total of your mortgage plus the new line at a percentage of the home's value. That percentage is the CLTV limit.

Fannie Mae's Selling Guide defines CLTV as the first mortgage amount, plus the drawn portion of any HELOC, plus the unpaid balance of other second loans, divided by the property's value. Fannie Mae uses a second ratio, HCLTV, that counts "the full amount of any HELOCs (whether or not funds have been drawn)". Fannie Mae writes these rules for first mortgages it buys, not for HELOC lenders, but they show the two ways a line can be measured. When a HELOC lender sets your limit, it counts the whole line you are asking for, because you could draw all of it.

Worked example: equity and the maximum line

Hypothetical inputs: home value $400,000, first mortgage balance $220,000, no other liens.

1. Equity = $400,000 minus $220,000 = $180,000 (45% of the value).
2. Current LTV = $220,000 ÷ $400,000 = 55.00%.
3. Maximum total debt at an 85% CLTV limit = $400,000 × 0.85 = $340,000.
4. Maximum line = $340,000 minus $220,000 = $120,000.
5. At an 80% limit: $400,000 × 0.80 = $320,000, minus $220,000 = $100,000.
6. Even at 85%, $60,000 of equity (15% of the value) stays unborrowed. That cushion is what protects the lender if prices fall.

To run your own numbers at 75%, 80%, 85% and 90% limits, use the HELOC borrowing limit calculator.

What credit score do you need for a HELOC?

Of the lenders on this page, two publish a number: Freedom Mortgage requires 640 and U.S. Bank requires a FICO score of 660 or higher. Bank of America and Navy Federal publish no minimum on the pages we read; Navy Federal says its rates are "based on credit history" along with loan-to-value and other factors. A score near a lender's floor usually narrows your choices and raises the price, and a higher equity cushion or lower DTI can matter more than a few points of score. If your score is in the low 600s, read can you get a HELOC with a 640 credit score for which lender types publish floors in that range and what to fix first.

How do lenders count your debt-to-income ratio?

The CFPB defines DTI as "all your monthly debt payments divided by your gross monthly income." For a HELOC, lenders add an estimate of the new HELOC payment to the debts you already pay. loanDepot lists what goes in: your current mortgage payment, "the projected payment for your new HELOC or HE Loan", property taxes and homeowners insurance, and other recurring debts.

Worked example: DTI with the new line

Hypothetical inputs: gross monthly income $8,000; mortgage payment including taxes and insurance $2,100; car loan $400. Line drawn: $40,000.

1. DTI today = ($2,100 + $400) ÷ $8,000 = $2,500 ÷ $8,000 = 31.25%.
2. Illustrative HELOC payment: interest only on $40,000 at a hypothetical 8.00% variable rate = $40,000 × 0.08 ÷ 12 = $266.67 a month. This is an illustration, not an offer. The rate on a real HELOC is usually variable and can change, a lender may qualify you on a higher principal-and-interest payment, and the figure excludes property taxes and insurance, which are already in the $2,100. On a plan with a 10-year interest-only draw and a 20-year repayment period at that constant rate, the schedule would be 120 payments of $266.67 followed by 240 payments of $334.58.
3. DTI with the line = ($2,500 + $266.67) ÷ $8,000 = $2,766.67 ÷ $8,000 = 34.58%.

That result sits under every published limit in the table above. For how lenders pick the payment they use, and what to do when the ratio lands near 43% or 50%, see HELOC debt-to-income limits. Our DTI calculator works out the ratio from your own figures.

For comparison, Fannie Mae's Selling Guide caps total DTI at 36% for manually underwritten first mortgages, up to 45% with stronger credit and reserves, and 50% for loans run through its automated system. HELOC lenders set their own limits, which is why the published figures differ.

Before you apply, check three numbers. Your mortgage balance from your latest statement, a realistic home value (recent nearby sales, not the highest estimate you can find), and your DTI with a principal-and-interest payment on the full line. If all three work on your numbers, you are inside the published equity and DTI rules above, subject to the lender's own appraisal and payment estimate. Check your credit score against each lender's minimum separately. That still is not an approval.

What documents do you need for a HELOC?

Rate's published checklist is typical: government-issued photo ID, recent mortgage statements, proof of homeownership, insurance information, a property appraisal, recent pay stubs, tax returns or W-2s for the past two years, and bank, retirement or investment account statements. Self-employed borrowers should expect to show more years of tax returns. Navy Federal notes that members "must carry homeowners' insurance on the property that secures the HELOC."

If the home is your principal dwelling, Regulation Z gives you a right to rescind the line until midnight of the third business day after it is opened (or after you receive the required notice and disclosures, if later). The CFPB booklet says that if you cancel in writing within that period, the lender must cancel its security interest in your home and return the fees you paid to open the account.

Shopping for a line. The service below compares HELOC options from several lenders. Loans Generator may be paid through an affiliate network when you click or submit a request; this does not change what we report. A HELOC is secured by your home: if you cannot repay it, you could lose your home. No lender has to approve you, and no rate or line amount is promised. If the home is your principal dwelling, you generally have three business days after the line opens to cancel it under Regulation Z, and the lender must return the fees you paid to open it.

What if you do not meet HELOC requirements?

• Not enough equity: wait for more principal paydown, or ask for a smaller line that keeps CLTV inside the limit.
• Score below the floor: fix report errors and lower card balances first; our guide to raising your score before a loan covers the steps.
• DTI too high: pay off a small installment debt, ask for a smaller line, or add a co-borrower whose income can be documented.
• You need the money for a short, defined project: an unsecured loan avoids putting your home up as collateral. Our home improvement loan vs HELOC flowchart walks through that choice, and using a HELOC to pay off credit cards covers the risk when the money goes to card debt.

What to do next

1. Work out your equity and the line size at an 80% and 85% CLTV limit.
2. Calculate DTI with a principal-and-interest payment on the full line, not only the interest-only figure.
3. Pull your credit reports and fix errors before any lender pulls your credit.
4. Gather the documents in the checklist above.
5. Compare at least three lenders on fees, the rate after any introductory period, the draw and repayment periods, and when the lender can freeze the line.

Common questions

How much equity do I need for a HELOC?

Enough that your mortgage plus the new line stays under the lender's CLTV limit. At an 85% limit you need more than 15% equity before any line is possible, and every dollar of line needs another dollar of equity above that cushion.

What is the minimum credit score for a HELOC?

It depends on the lender. Freedom Mortgage publishes 640 and U.S. Bank publishes 660 (FICO). Bank of America and Navy Federal publish no number on the pages we read.

Do lenders count the HELOC payment in my DTI?

Yes. loanDepot lists "the projected payment for your new HELOC or HE Loan" as part of the DTI calculation. Lenders vary in whether they use an interest-only or a principal-and-interest payment.

Do I need an appraisal for a HELOC?

Usually some valuation of the home. Rate lists a property appraisal in its documents, and the CFPB lists an appraisal fee among common HELOC fees. Some lenders use automated valuations for smaller lines.

Can I lose my home with a HELOC?

Yes. The CFPB warns that if you fall behind or cannot repay on schedule, you could lose your home. The line is secured by a lien on the property.
