To qualify for a Home Equity Line of Credit (HELOC), most lenders want to see your debt-to-income (DTI) ratio below 43%. If your credit is excellent, some lenders may allow up to 50%. If it’s fair, you’ll likely need to stay under 40%.
DTI is one of the most important metrics used to evaluate whether you can manage a new monthly loan payment — and ultimately, whether you’re eligible to tap into your home equity.
How to Choose Between HELOC and a Home Equity Loan
A HELOC works like a credit card with a flexible credit line you can draw from as needed, while a home equity loan provides a lump-sum payout with fixed payments over time.
To choose between them, consider whether you need predictable monthly payments (home equity loan) or flexible access to funds over time (HELOC) based on your financial goals.
How DTI Is Calculated for HELOCs
Lenders use two versions of DTI:
- Housing Ratio (Front-End DTI): Only includes mortgage-related costs
- Total Ratio (Back-End DTI): Includes all debts, plus your projected HELOC payment
If you’re unsure how a HELOC payment would fit into your budget, you can estimate it using HomeEQ’s HELOC loan calculator.
Formula Example:
Let’s say you earn $8,000/month and your total monthly debt (including your new HELOC payment) is $2,950:
($2,950 ÷ $8,000) × 100 = 36.9% DTI
That would fall well within most lenders’ comfort zone.
DTI Guidelines by Lender Type
Different types of lenders have varying debt-to-income (DTI) limits and underwriting flexibility when it comes to HELOCs:
- Major Banks typically cap total DTI at 43%, with a housing DTI limit of 28%. These institutions tend to follow stricter, more conservative lending guidelines and often require strong credit profiles.
- Credit Unions are a bit more flexible, allowing up to 45% total DTI and 30% for housing DTI. Because they are member-focused, they may offer more personalized service and leniency.
- Online Lenders often use automated underwriting and offer the widest DTI range — from 43% to 50% total DTI and 28% to 35% for housing DTI. Approval is typically credit-score driven and designed for speed and convenience.
- Portfolio Lenders may allow total DTIs of up to 55% with housing DTI limits around 35%. These lenders evaluate borrowers on a case-by-case basis and may consider total assets or alternative credit factors.

What Debts and Income Are Included?
Counted Toward DTI:
- Your current mortgage (principal, interest, taxes, insurance)

- Childcare and insurance premiums
- Property maintenance or repairs
Typical HELOC Timeline
Debts and incomes are verified during the HELOC approval process.
- Prequalification (same day): Many online lenders offer instant soft-pull prequalification.
- Application & Documentation (1–3 days): Submit income, asset, and property info.
- Underwriting (3–7 days): Lender verifies credit, debt-to-income ratio, and home equity.
- Appraisal or Valuation (0–7 days): Some lenders waive this or use automated valuation models (AVMs).
- Closing & Funding (3–5 days): After approval, you’ll sign documents and wait for the 3-day right of rescission (required by law).
Fast-Track Tip: Choose a digital lender that offers automated income and asset verification — this can cut the timeline to under 10 days, especially if no appraisal is required.
Credit Score vs. DTI: How They Work Together
Your credit score helps determine how much wiggle room you have with DTI limits:
- 740+ FICO: Lenders may accept up to 50% DTI
- 680–739 FICO: 43% DTI is typically the ceiling
- 620–679 FICO: Expect a limit around 40%
Estimating HELOC Payments for DTI
HELOC payments can be structured in a few different ways:
- Interest-only during the draw period (some lenders still use this for DTI estimates)
- Principal + interest amortized over 10–20 years (most common)
- 1% rule of thumb — some lenders use 1% of the total line amount to calculate a conservative estimate
Regardless of which method is used, the key is ensuring your total DTI — including the new HELOC — remains within your target range.
Ways to Improve Your DTI Before Applying
If your DTI is above 43%, here’s how to improve:
- Pay Down Existing Debt: Focus on high-balance credit cards first. Reducing revolving debt can have a big impact fast.
- Increase Your Documented Income: Include bonuses, side gigs, or a co-borrower if possible.
- Apply at the Right Time: If you’ve just received a raise or paid off a loan, wait until it’s reflected on your credit or pay stub before applying.

Quick Answers to Common DTI Questions
Can I still get approved with a DTI over 43%?
Yes, if you have excellent credit or lots of equity, some lenders will go up to 50%.
Does paying off a car or credit card help?
Absolutely. But wait until the payoff is reflected on your credit report — or bring proof when you apply.
What about variable or seasonal income?
Lenders will typically average your last 2 years of income. If your income fluctuates, be prepared to show consistent earnings over time.
