To qualify for a HELOC, you generally need a credit score of at least 680, enough equity in your home to keep your combined loan-to-value ratio at or below 85 percent, and a debt-to-income ratio within your lender’s cap, which usually falls between 43 and 50 percent. You’ll also need to document a steady income, let the lender establish a current value for your home, and pass a review of your full credit history — not just the score.
Credit Score You’ll Need
Most lenders set 680 as the minimum score for HELOC approval. Some will go as low as 620 if you have strong equity or income to offset the risk. Scores of 740 and above typically unlock the lowest rates, while borrowers in the 680 to 739 range can qualify but should expect a higher margin added to their rate.
A high score alone isn’t enough. Lenders read your full credit report for patterns. A long history of on-time payments carries more weight than a high number built on a thin or recently opened profile. Multiple late payments, accounts in collections, or a cluster of recent hard inquiries can lead to a denial or significantly worse terms, even with a score above the minimum.
If a lender offers you less favorable terms because of something in your credit report, federal regulations require them to send you a risk-based pricing notice explaining that decision.1eCFR. 12 CFR Part 1022 Subpart H – Duties of Users Regarding Risk-Based Pricing That gives you a chance to review your credit data and dispute any errors before accepting the offer.
Equity in Your Home
Your available equity determines how much you can borrow. Lenders calculate your combined loan-to-value (CLTV) ratio by adding your existing mortgage balance to the HELOC credit limit you’re requesting, then dividing that total by your home’s current appraised value.2Fannie Mae Selling Guide. B2-1.2-02, Combined Loan-to-Value (CLTV) Ratios Most lenders cap the CLTV at 85 percent, meaning you need to keep at least 15 percent equity after the new line is in place.
Take a $400,000 home. The total of your mortgage balance plus the new HELOC cannot exceed $340,000 under an 85 percent cap. If you still owe $280,000 on your first mortgage, your maximum HELOC credit limit would be $60,000.
How Your Home Gets Valued
Lenders need a current property value to run the CLTV math. Traditionally, that meant hiring a certified appraiser to inspect the home inside and out and compare it to recent nearby sales. An in-person appraisal typically costs between $300 and $700 depending on the size and location of the home.
Most HELOC originations now rely on automated valuation models, which use public records and sales data to estimate value, or on desktop valuations that involve no physical inspection. Lenders are more likely to waive a traditional appraisal if you have a strong credit score and are borrowing a modest amount compared to your equity. If a full appraisal is required, the cost is typically passed to you as part of closing.
Property Type Matters
Single-family homes face the fewest hurdles. Condominiums often carry tighter restrictions. Many lenders cap CLTV lower for condos, closer to 70 to 80 percent, and scrutinize the condo association’s financials, owner-occupancy rate, insurance coverage, and any pending litigation before approving a line. Some lenders won’t offer HELOCs on condos at all. Investment properties and manufactured homes may face additional requirements or outright exclusions depending on the lender.
Debt-to-Income Ratio
Your DTI ratio measures how much of your gross monthly income already goes to debt payments. Add up your mortgage, the projected HELOC payment, car loans, student loans, and minimum credit card payments, then divide by your gross monthly income. Most HELOC lenders want that number at or below 43 percent, though some allow up to 50 percent if you bring strong compensating factors — excellent credit, significant equity, or substantial cash reserves.
For loans sold to Fannie Mae, the ceiling depends on how the loan is underwritten. Manually underwritten loans top out at 36 percent, or up to 45 percent with strong credit scores and reserves. Loans processed through Fannie Mae’s automated underwriting system can go as high as 50 percent.3Fannie Mae Selling Guide. B3-6-02, Debt-to-Income Ratios Borrowers approved at the higher end of the range should expect a higher interest rate or a lower credit limit as a tradeoff.
Income and Employment History
Lenders look for at least a two-year history of stable employment income, supported by recent pay stubs and W-2 forms covering that period.4Fannie Mae Selling Guide. B3-3.1-03, Base Pay (Salary or Hourly), Bonus, and Overtime Income A shorter history may be acceptable when your profile shows positive factors, such as graduating and immediately starting a well-paying job in your field.
Self-employed borrowers face additional scrutiny. Expect to provide at least two years of personal and business tax returns, along with profit-and-loss statements or a CPA letter verifying your income. Significant year-over-year income drops or recent gaps in employment can result in a denial or a requirement for a co-signer.
Documents to Have Ready
Having a complete document package before you apply prevents back-and-forth delays. Lenders typically ask for:
- W-2 forms from the past two years and pay stubs from the most recent 30 days, or tax returns and profit-and-loss statements if you’re self-employed
- Your most recent mortgage statement showing the outstanding principal balance on your first mortgage
- Proof of a current homeowners insurance policy, since lenders require coverage to protect their collateral
- Property details, including the address, an estimated value, and information about any other liens
- A list of your assets (bank accounts, investments) and liabilities (car loans, credit cards, other debts)
Federal regulations require the lender to give you a brochure titled “What You Should Know About Home Equity Lines of Credit,” or a suitable substitute, at the time you receive the application.5eCFR. 12 CFR 1026.40 – Requirements for Home Equity Plans The lender also cannot charge any nonrefundable fees until three business days after you’ve received the brochure and required disclosures.
Closing Costs to Plan For
HELOC closing costs generally run between 1 and 5 percent of your credit limit. The exact amount depends on your lender, loan size, and location, but common charges include:
- Appraisal fee of $300 to $700, if a traditional appraisal is required
- Origination fee, typically 0.5 to 1 percent of the credit limit
- Title search, $75 to $200, to confirm there are no unexpected liens
- Recording fees, $15 to $50, paid to your local government to record the lien
- Credit report fee of $20 to $50
Some lenders waive closing costs or roll them into the line. Read the fine print, because waived costs often come with a requirement to keep the line open for a minimum period or pay a cancellation fee. Beyond closing, watch for recurring charges: annual maintenance fees, inactivity fees if you don’t draw within a set period, and transaction fees on individual withdrawals. Ask about every ongoing fee before you sign.
From Application to Funded Line
You can submit your application through the lender’s online portal, over the phone, or at a branch. Once received, the lender begins underwriting: verifying income, pulling credit, and ordering a property valuation. When documents are complete and no issues surface, the process from application to funding typically takes about 30 days, though some lenders advertise approval within two weeks when borrowers turn documents around quickly.
After the underwriter gives final approval, you’ll attend a closing, either in person or with a mobile notary, to sign the loan agreement and security instruments. Federal regulations then give you a three-business-day right of rescission, a cooling-off period during which you can cancel the agreement for any reason. The lender cannot disburse any funds or activate your line until that window passes.6eCFR. 12 CFR 1026.15 – Right of Rescission Once it does, the line is active and you can start drawing funds.
