The 30-second answer
Mainstream HELOC lenders want a minimum FICO of 680. Best pricing kicks in at 740+. A borrower between 620-680 can usually find a HELOC but pays a rate premium of 1.5-3.0 percentage points and faces stricter LTV limits (typically 70-80% CLTV instead of 85%). Below 620, options narrow to specialty non-QM and portfolio lenders with even higher premiums. Compensating factors — high equity, low DTI, cash reserves, clean mortgage history — matter more than the FICO score in isolation.
What "bad credit" actually means for HELOC approval
Lenders don't think in terms of "good" or "bad" — they think in credit tiers, each of which corresponds to a specific pricing bucket and set of overlays:
| FICO tier | Typical availability | Rate premium over best tier | Max CLTV |
|---|---|---|---|
| 780+ | All lenders, best pricing | Baseline | 85-90% |
| 740-779 | All lenders | +0.00% to +0.25% | 85% |
| 700-739 | Most lenders | +0.25% to +0.75% | 85% |
| 680-699 | Most lenders | +0.50% to +1.25% | 80-85% |
| 640-679 | Some mainstream + non-QM | +1.00% to +2.50% | 75-80% |
| 620-639 | Non-QM and portfolio only | +2.00% to +3.50% | 70-75% |
| Under 620 | Specialty only | +3.00% to +5.00%+ | 60-70% |
The most important thing to notice: below 700 the game shifts from "which lender's rate is best" to "which lender will even look at this file." Shopping matters more, not less, when credit is imperfect.
Why the rate premium exists (it's not what most people think)
Borrowers often assume the rate premium is punishment for past credit mistakes. It's not. It's actuarial pricing.
A lender who books 1,000 HELOCs at 740+ FICO can expect roughly 1-2% default rates over the life of the line. At 620-680, defaults roughly triple. The rate premium is the lender covering the higher expected loss rate across the pool of similar borrowers — not a moral judgment about any individual file.
This matters because it tells you how to negotiate. If you can present compensating factors that lower the expected loss rate on your file (high equity, cash reserves, stable job history), the rate premium should shrink. Underwriters have discretion within pricing tiers.
The five compensating factors that unlock bad-credit HELOCs
These are the levers that turn a borderline file into an approval:
1. Equity above 40%. The most important compensating factor by far. A HELOC lender's downside risk is bounded by the equity cushion. A borrower at 620 FICO with 55% equity is a much better risk than one at 660 FICO with 15% equity. Every point below 700 gets partially offset by every 5 points of equity above 40%.
2. Clean mortgage payment history. Twelve to 24 months of on-time mortgage payments carries enormous weight even if the FICO is dragged down by credit cards, medical collections, or old lates. The lender cares most about the debt you're most likely to prioritize — your primary mortgage — and if that history is spotless, they'll often overlook other blemishes.
3. Documented income and low DTI. A back-end DTI under 40% with fully documented W-2 income is a significant offset. If DTI including the new HELOC payment stays under 40%, lenders find room to approve marginal FICOs. Above 45% DTI, no compensating factor overcomes the debt-load concern.
4. Cash reserves. Six months of full PITI + HELOC payment sitting in a bank account demonstrates that a job loss or income disruption doesn't immediately create a delinquency. This is powerful. Reserves are the single easiest compensating factor to show if you have savings.
5. Explanation letters for old derogatories. A specific, believable, documented story for the negative marks on your report — medical event, divorce, business loss followed by recovery — helps underwriters understand the file as "one-time event, recovered" rather than "chronic pattern." This won't override structural issues, but it moves close calls to the approve side.
What kills a bad-credit HELOC file
Some issues are dealbreakers regardless of compensating factors:
Recent mortgage lates. Even one 30-day late on your primary mortgage in the last 12 months makes a HELOC nearly impossible. This is the one late that matters most.
Bankruptcy under 4 years old. Chapter 7 typically requires 4 years discharged for HELOC eligibility, Chapter 13 requires 2 years after discharge or 4 years after dismissal.
Foreclosure under 7 years old. Some non-QM lenders shorten this to 3-4 years with strong compensating factors, but mainstream HELOCs require 7.
Active collections over $2,000. Medical collections are often forgiven; commercial collections typically must be paid off at or before closing.
DTI over 50%. Regardless of credit score, most HELOC lenders cap total DTI at 43-50%. Add the new HELOC payment and you have to stay under.
Should you wait to improve credit first?
Often yes. Here's when waiting pays off and when it doesn't:
Wait if your low score is being driven by high revolving utilization, a few recent lates that will age off, or credit errors you can dispute. These are fixable in 60-120 days and can move you a full tier — from 640 to 700, which changes your rate by roughly 1-1.5 percentage points and opens up better lenders. On a $50,000 balance, that's $750/year in savings for a couple months of work.
Don't wait if your low score is driven by older structural issues (bankruptcy, foreclosure, chronic pattern) that won't move materially with short-term action. You'll get roughly the same terms in six months as today, so applying now and using the HELOC to consolidate/pay down debt often accelerates the score improvement more than waiting does.
Don't wait if Prime is expected to rise before your score improves. A 50-basis-point rise in Prime can wipe out a full tier of credit-score improvement. In an uncertain rate environment, locking in today's rate at a moderate premium can beat waiting for a slightly lower spread on a higher base.
The lender's honest verdict
If you're in the 640-700 range, HELOCs are available at a rate premium that's often smaller than the rate you're paying on the debt you're trying to consolidate. A 640 borrower paying 24% on cards who gets a 9.5% HELOC is still saving 14+ points. The premium matters, but not as much as some articles make it sound.
If you're below 620, the honest advice is usually to work on credit first for 6-12 months, unless you have overwhelming compensating factors (60%+ equity, high income, no derogatories in 24 months). The rates and terms available at that tier are punitive enough that the HELOC often stops making sense against alternatives.

FAQ
What's the minimum credit score for a HELOC in 2026?
Most mainstream lenders require 680 minimum, with best pricing at 740+. Some non-QM lenders go to 620-640 with tighter LTV and higher rates.
Can I get a HELOC with a 580 credit score?
Difficult but possible with 40%+ equity, strong income documentation, no recent mortgage lates, and 6+ months of reserves. Rates run Prime + 3% to Prime + 5%.
How much higher is the rate on a bad-credit HELOC?
For 620-680 vs 740+, expect 1.5-3.0 percentage points higher. Below 620, the premium widens to 3-5 points if a lender will approve.
Should I wait to improve my credit before applying for a HELOC?
Yes if your score is being dragged down by fixable issues (utilization, disputes, recent lates aging off). No if the issues are older and structural, or if Prime rates are expected to rise before your score improves.
