HELOC Requirements: Credit Score and Equity Minimums and How to Qualify
Most HELOC lenders require a 680-700 credit score, at least 15-20% equity in your home, and a combined loan-to-value ratio of 80-90% or less. Your existing first mortgage balance plus the HELOC cannot exceed the CLTV limit. Income documentation and DTI requirements apply just like a mortgage — you are borrowing against your home, and lenders underwrite accordingly.

Credit Score
- Minimum: Most HELOC lenders require 680-700 FICO minimum, with some going as low as 620 at higher rates and lower CLTV limits
- Best rates: 740+ FICO gets the best HELOC rates — the spread between 680 and 740 can be 1-2% in rate, translating to significant interest savings
- Below 680: Options narrow to credit unions, a few online lenders, and portfolio products — expect higher rates and lower credit lines
- Action: Check your credit score before applying and address any errors on Experian and TransUnion reports first
Equity Requirements
- Minimum equity: Most lenders require at least 15-20% equity in your home after accounting for the first mortgage balance
- CLTV limit: Combined loan-to-value (first mortgage + HELOC) typically capped at 80-90% depending on the lender and your credit profile
- Calculation: Home value minus first mortgage balance equals available equity — multiply home value by CLTV limit and subtract first mortgage for your max HELOC
- Action: Estimate your home value using recent comparable sales, then calculate available equity at 80% CLTV to see your maximum line amount
Income & DTI
- Income docs: HELOC lenders require income verification — W-2s, pay stubs, or tax returns for self-employed borrowers, similar to a mortgage application
- DTI limit: Most HELOC lenders cap DTI at 43-50% including all existing debt payments plus the projected HELOC payment
- HELOC payment for DTI: Lenders typically calculate the HELOC payment as 1% of the credit limit or the interest-only payment at the fully drawn amount
- Action: Calculate your current DTI before applying — add 1% of your desired HELOC amount as a monthly payment to see if you stay under 43%
Property Requirements
- Property type: Primary residence is the easiest to qualify — second homes and investment properties are eligible at some lenders with stricter terms
- Appraisal: Most HELOC applications require a property appraisal or automated valuation model (AVM) to confirm home value and available equity
- Title: A title search confirms your ownership and identifies any existing liens — the HELOC lender needs clear subordinate lien position
- Action: HELOCs on condos may require additional project review similar to a mortgage — check with your lender on property type restrictions

The Bottom Line Up Front
Qualifying for a HELOC is similar to qualifying for a mortgage — lenders check credit, equity, income, and DTI. The primary difference is that HELOC lenders focus on combined loan-to-value rather than purchase LTV, and most require higher credit scores than first mortgage programs.
The 680-700 minimum credit score requirement is the biggest barrier for most borrowers. FHA mortgages require only 580, but HELOCs have no government backing — they are portfolio products where the lender holds the risk. That means the lender sets the rules, and most set them conservatively. If your credit is below 680, you may need to improve it before a HELOC becomes available, or consider a home equity loan or cash-out refinance as alternatives.
What Credit Score and Equity Do You Need?
Most HELOC lenders require 680-700 minimum FICO and at least 15-20% equity. The better your credit and equity position, the larger the line and lower the rate.
HELOC underwriting is more credit-driven than first mortgage underwriting because there is no government guarantee. FHA, VA, and Fannie Mae/Freddie Mac all provide lenders with insurance or guarantees that reduce risk on first mortgages. HELOCs have no such backstop — the lender absorbs the full loss if you default. This is why credit requirements are higher.

Approval Watchpoint
Your available HELOC amount is capped by CLTV, not just equity. If your home is worth $350,000 and your first mortgage is $300,000 (86% LTV), you have $50,000 in equity — but at an 80% CLTV cap, your max HELOC is $0 ($350,000 × 80% = $280,000, which is less than your $300,000 first mortgage). You need the first mortgage below the CLTV threshold before a HELOC becomes available.
How Do HELOC Lenders Calculate Your DTI?
HELOC lenders calculate DTI the same way mortgage lenders do — total monthly debt obligations divided by gross monthly income. The HELOC payment is added to your existing obligations.
The key question is how the lender calculates the HELOC payment for DTI purposes. Most lenders use the interest-only payment at the fully drawn credit limit, even if you plan to draw less. Some use 1% of the credit limit as a monthly payment proxy. Either way, a $100,000 HELOC at 9% adds $750/month to your DTI whether you draw the full amount or not.
- HELOC payment for DTI is typically calculated on the full credit limit, not the initial draw — a $75,000 HELOC at 9% = $562.50/month interest-only payment added to your DTI
- Most HELOC lenders cap DTI at 43-50% including the first mortgage, HELOC payment, and all other debt obligations — this is similar to first mortgage DTI standards
- Income documentation requirements mirror mortgage standards: 2 years of W-2s and recent pay stubs for employed borrowers, 2 years of tax returns for self-employed
- Some credit unions and portfolio lenders offer asset-based HELOC qualification where strong reserves can offset income shortfalls — ask about alternative qualification methods if your income is irregular
How to Improve Your Chances of HELOC Approval
If your credit, equity, or DTI is borderline, there are specific actions you can take to improve your HELOC approval odds before applying.
- Pay down revolving credit card balances to below 30% utilization before applying — this can boost your FICO by 20-40 points, potentially crossing the 680 or 700 threshold
- Pay down your first mortgage to reduce CLTV — every dollar of additional principal payment creates a dollar of additional HELOC borrowing capacity under the CLTV cap
- Request a smaller HELOC than you might want — a $50,000 line at 80% CLTV is easier to approve than a $100,000 line at 90% CLTV, and you can request a limit increase later
- Apply at a credit union where you have an existing relationship — member credit unions often have lower minimum credit scores and more flexibility on CLTV and DTI than large banks
- If your credit is below 680, consider a home equity loan (fixed-rate second mortgage) instead — some lenders have lower credit score requirements for fixed-rate home equity loans than for revolving HELOCs
Lender Reality Check
HELOC underwriting has tightened since 2022 as home values plateaued in some markets. Lenders that offered 90% CLTV HELOCs in 2021 now cap at 80% in markets with softening values. If you are in a market where home values have declined, your available HELOC may be smaller than expected because the appraised value dropped even if your equity percentage has not changed.
What Are the Costs of Getting a HELOC?
HELOC closing costs are typically lower than mortgage closing costs. Many lenders waive fees entirely or charge only a few hundred dollars for appraisal and title.
- Many HELOC lenders waive closing costs entirely as a promotional incentive — check whether the waiver is conditional on keeping the line open for a minimum period (usually 2-3 years)
- When closing costs apply, expect $0-$2,000 total covering appraisal or AVM ($0-$600), title search ($150-$300), recording fees ($50-$200), and possibly an origination fee ($0-$500)
- Annual fees of $25-$75/year are common on HELOCs — some lenders waive the annual fee if the line has a balance or if the borrower maintains a minimum balance in a checking account
- Early termination fees of $300-$500 apply at some lenders if you close the HELOC within 2-3 years of opening — this is the lender’s way of recovering waived closing costs if you leave quickly
Deal Saver
If you are not sure you need a HELOC right now but want the option available, open the line while you qualify. There is no cost to have an open HELOC with a $0 balance if the lender has waived closing costs and the annual fee is minimal. Having a HELOC available gives you instant access to equity without needing to reapply if an emergency or opportunity arises.
The Bottom Line
HELOC qualification requires stronger credit than a first mortgage (680+), sufficient equity (15-20%+ after the first mortgage), and DTI under 43-50%. The requirements are firm because HELOCs have no government backing — the lender holds all the risk.
If your credit is below 680, work on it before applying. If your CLTV is above the lender’s cap, pay down the first mortgage or wait for appreciation. And compare at least three HELOC lenders — credit unions, banks, and online lenders often have meaningfully different credit score floors, CLTV limits, and rate tiers for the same borrower profile.
Frequently Asked Questions
Can I get a HELOC on a second home?
Yes, some lenders offer HELOCs on second homes, but requirements are stricter — typically 700+ credit score, 75% CLTV maximum, and higher rates. Not all HELOC lenders finance second homes, so you may need to shop specifically for lenders that offer this product.
Can I get a HELOC on an investment property?
Very few lenders offer HELOCs on investment properties. The risk is higher because the borrower does not live in the collateral. If available, expect 720+ credit score, 70-75% CLTV maximum, higher rates, and a limited pool of lenders. A cash-out refinance on the investment property may be a more readily available alternative.
How long does it take to get a HELOC?
Most HELOCs close in 2-6 weeks from application. If the lender uses an AVM instead of a full appraisal, the process is faster. Credit unions and smaller banks sometimes close in 2-3 weeks. Large banks may take 4-6 weeks due to processing volume.
Can I get a HELOC if I just bought my house?
Most lenders require a seasoning period of 3-12 months after purchase before approving a HELOC. Some lenders will approve immediately if you can demonstrate significant equity (20%+ down payment on the purchase). Check with your lender on their specific seasoning requirements.
Is a HELOC better than a personal loan?
A HELOC typically has a much lower interest rate than a personal loan (8-10% vs 12-20%+) and higher credit limits. However, a HELOC is secured by your home — if you cannot make payments, the lender can foreclose. A personal loan is unsecured and has no foreclosure risk. Use a HELOC for larger amounts where the rate savings justify the home collateral risk.
What happens to my HELOC if I sell my house?
The HELOC balance is paid off from the sale proceeds at closing, just like the first mortgage. The title company handles the payoff and releases the lien. If you have an unused HELOC with a $0 balance, it is still closed at sale and the lien is released. There is no penalty for closing the HELOC through a sale.
