Four numbers decide approval. Here's exactly where the bar sits, and what to do if you're short on one of them.
Lenders don't approve HELOCs on gut feel, they run four numbers. Hit all four and you'll qualify almost anywhere. Fall short on one and you'll either get declined or pushed into a worse rate. Here's what each one actually means, where the real bar sits in 2026, and what to do if you're not quite there yet.
Most lenders cap your combined loan-to-value (CLTV) at 80-85%, meaning your mortgage balance plus the new HELOC can't exceed that share of your home's appraised value. This is the number that decides whether you can apply at all, everything else affects your rate and terms.
Real example: Home worth $400,000. Mortgage balance $250,000.
At 85% CLTV, your max combined debt is $340,000, meaning you could access up to $90,000 in a HELOC.
The floor is lower than most people assume. But the real breakpoints, the ones that change your actual outcome, sit higher:
| Score range | What it gets you |
|---|---|
| 620–639 | Approval possible at select lenders, expect a higher rate |
| 640–679 | Standard approval range for most online lenders and credit unions |
| 680–719 | Qualifies with major banks, meaningfully better rate tier |
| 720+ | Best available rate and highest CLTV limits |
The gap between a 640 and a 760 score isn't small. On a $100,000 HELOC, it can run a full percentage point or more, roughly $1,000/year in extra interest for the exact same loan.
Lenders add up your total monthly debt, including the new HELOC payment, and divide it by your gross monthly income. Stay under 43% and you're in good shape. Some lenders flex up to 50% for otherwise strong applicants.
Real example: $6,000/month gross income, $2,000/month in existing debt.
That's a 33% DTI before the HELOC, plenty of room. Add a $400/month HELOC payment and you're still under 40%.
Expect to gather these before you apply, having them ready is the single easiest way to speed up approval:

A late mortgage payment in the past 12 months is close to an automatic decline regardless of everything else, that one's non-negotiable. But outside of that, the four factors above trade off against each other more than most people realize. Strong income and low DTI can offset a lower credit score. High equity can offset a thinner credit file. The fastest fix is usually shopping multiple lenders, not waiting a year to improve one number in isolation while the other three sit fine.
As of mid-2026, the national average HELOC rate sits around 7.17% APR. Borrowers with 740+ credit scores and 80% or lower CLTV are seeing rates as low as 6.25-7.00% at the best-pricing lenders, a meaningful gap from the average, and proof that the numbers above aren't just approval hurdles, they directly set your price.
It's difficult but not always impossible. A handful of lenders will consider scores in the high 500s to low 600s if your equity and income are unusually strong, but your options and rate will both be worse. Getting to 620+ first opens meaningfully more doors.
Applying triggers a hard inquiry, which can cause a small, temporary dip. Shopping multiple lenders within a short window (typically 14-45 days) is usually treated as a single inquiry for scoring purposes.
Paying down credit card balances below 30% utilization can lift your score within one to two billing cycles. Disputing errors on your credit report can add points within 30-45 days once corrected. Both are faster wins than waiting out negative history.
No, but adding one with stronger credit or income can help you qualify or unlock better terms. Keep in mind both borrowers become equally responsible for repayment.
Your CLTV is the number every lender starts with. Run your numbers first so you know your real borrowing range before you talk to anyone.
