HELOC Credit Score Requirements in CO
640. That's the minimum credit score for a HELOC on a primary residence through our network. Not 700. Not 720. Not the number your bank quoted you. 640.
Most banks set their floor at 700 or higher because it's easier for them. Fewer risk profiles to evaluate, fewer files to underwrite. That's their convenience, not your benefit.
I work with homeowners across the entire credit spectrum — from 640 to 800+. The score changes your rate and your maximum CLTV, but it doesn't change whether you get access to your own equity.
What Each Credit Tier Gets You
Your FICO score determines three things: your rate (margin above prime), your maximum CLTV, and your maximum loan amount. Here's the breakdown:
| Credit Score | Max CLTV (Primary) | Max Loan Amount | Rate Impact | Best For |
|---|---|---|---|---|
| 640-679 | Up to 80% | $25,000-$400,000 | Higher margin above prime | Homeowners banks turned away |
| 680-719 | Up to 85% | $25,000-$400,000 | Moderate margin | Second homes and investment |
| 720-759 | Up to 85% | $25,000-$400,000 | Lower margin | Strong rate on standard HELOCs |
| 760+ | Up to 85% (75% over $400K) | $25,000-$750,000 | Lowest margin available | Large HELOCs over $400K |
The big jump is at 760. That's where HELOCs over $400,000 become available — with a 75% max CLTV and a full appraisal required. Below 760, you're capped at $400,000 but still have access to strong terms.
Look. The difference between a 660 and a 720 score matters on rate — but both get you a HELOC. Both get you access to your equity. Don't let a number stop you from checking.
Not Sure Where You Stand?
The initial check is a soft pull — no impact on your score. I'll tell you exactly what you qualify for.
Get Your Equity BlueprintWhat Actually Moves Your Credit Score
If you're sitting at 620 or 635 and need to get to 640, there are specific actions that move the needle fast. I tell homeowners to focus on these two things:
1. Pay Down Credit Card Balances Below 30% Utilization
Credit utilization — how much of your available credit you're using — makes up about 30% of your FICO score. If you have $20,000 in credit limits and $15,000 in balances, your utilization is 75%. That crushes your score.
Pay those balances down to $6,000 (30% utilization) and you could see a 20-40 point jump within 30-45 days. Pay them below $2,000 (10%) for the maximum boost.
Here's the thing. You don't need to pay them off entirely. Just getting below 30% utilization on each card triggers a scoring bump at the next reporting cycle.
2. Dispute Errors on Your Credit Report
About 1 in 5 credit reports contain errors according to the FTC. An incorrect late payment, a balance that's reporting wrong, or an account that isn't yours can drag your score down 20-50 points. Pull your reports from all three bureaus and dispute anything that's inaccurate.
These two moves alone — utilization and error disputes — can shift your score 30-60 points in 45 days. That's often the difference between a "no" from your bank and a "yes" from us.
From 635 to 650 in 45 Days. Then $180K in Equity.
Greg in Longmont called us about a HELOC. Home worth $560,000, mortgage balance $210,000 at 3.5%. Plenty of equity. But his FICO was 635 — five points below our minimum.
His bank had already said no at their 700 floor. He was frustrated.
I looked at his credit profile. Two things jumped out: his credit card utilization was at 68% ($8,200 across $12,000 in limits), and one card was reporting a late payment from 2023 that he said was paid on time.
I told him: pay the cards down below 30% utilization ($3,600 total) and dispute that late payment with documentation. He did both that week.
45 days later, his score updated to 652. The utilization drop added 22 points. The disputed late payment was removed and added another 15.
We ran his HELOC at 652. Approved at 80% CLTV on his primary residence: $238,000 in accessible equity. He drew $180,000 — $120,000 for a rental property down payment in Greeley and $60,000 for debt consolidation.
Two small changes. 45 days. $180,000 in equity access that his bank told him he couldn't have.

Why We Don't Require 700+
Honestly, the 700-minimum that most banks set is arbitrary. It's a risk management shortcut — they don't want to underwrite nuanced credit profiles, so they set the bar high and turn away qualified homeowners.
A homeowner with a 650 FICO, $200,000 in equity, stable income, and a clean payment history for 12+ months is a good credit risk. Their score might be lower because of a medical collection from three years ago or high utilization on a single card. Neither of those things means they can't handle a HELOC payment.
Our network starts at 640 because the equity in the home is the primary collateral. If you own the home and you have the equity, the score determines your terms — not whether you get access.
Second Homes and Investment Properties: 680 Minimum
The rules change for non-primary residences. If you want a HELOC on a vacation home or a rental property, the floor is 680. The reason is straightforward: if finances get tight, people prioritize their primary residence. The risk on a second home or investment property is higher, so the credit bar is higher.
Everything else — loan amounts, terms, draw periods, no prepayment penalties — stays the same. The rate margin is slightly higher, and CLTV limits are typically tighter than primary residence. But if you have a 680+ score and equity in a mountain property or a rental in the Springs, a HELOC is absolutely available.
The $400K Threshold: 760 Required
HELOCs over $400,000 have separate requirements:
| Requirement | Standard HELOC | Over $400K |
|---|---|---|
| Min Credit Score | 640 primary / 680 non-primary | 760 |
| Max CLTV | Up to 85% | 75% |
| Appraisal | AVM under $400K | Full appraisal required |
| Occupancy | Primary, second, investment | Owner-occupied only |
| Max Amount | $400,000 | $750,000 |
This tier exists for high-equity homeowners — typically Denver, Boulder, and mountain market properties where $400,000+ HELOCs are common. If you're in this range and your score is 760+, you have access to the largest lines available.
SCORE TIP
Don't apply for new credit cards, auto loans, or other debt in the 90 days before your HELOC application. New credit inquiries and new accounts temporarily lower your score. If you're close to a threshold (640, 680, or 760), even 5-10 points can make a difference.
