Most lenders want you to have at least 15% to 20% equity in your home before they will approve a HELOC. Some specialty HELOC lenders go up to 85% combined loan-to-value (CLTV), meaning you can borrow against everything except 15% of your home’s value. A few will stretch to 90% or even 100% CLTV, but those programs are rarer and cost more.
What Equity Means
Equity is the part of your home you actually own. To find it, take your home’s current value and subtract what you still owe on your mortgage.
Example: Your home is worth $400,000. You owe $250,000 on your mortgage. Your equity is $150,000. That equals 37.5% equity in your home.
Lenders care about equity because it protects them. If you stop paying, they can sell your home to get their money back. The more equity you have, the safer the loan is for the lender.
The 15% to 20% Rule
Most HELOC lenders want you to keep at least 15% to 20% of your home’s value as equity after the loan. That means the total of your first mortgage plus your HELOC cannot go above 80% to 85% of your home’s value.
The math the lender uses is simple:
Maximum HELOC = (Home Value × Max CLTV%) − Current Mortgage Balance
Example with 85% CLTV:
- Home value: $400,000
- Current mortgage: $250,000
- Max total liens at 85%: $340,000
- Max HELOC available: $340,000 − $250,000 = $90,000
At a 7.17% interest rate (the national HELOC average as of March 2026), a $90,000 HELOC at interest-only payments would cost roughly $538 per month during the draw period (Bankrate, 2026).

Equity Requirements by CLTV Tier in 2026
Different lenders allow different CLTV limits. Here is what to expect:
- 80% CLTV (most common): Requires 20% equity after the HELOC. Best rates available.
- 85% CLTV (very common): Requires 15% equity after the HELOC. Slightly higher rates.
- 89% to 90% CLTV (less common): Requires 10% to 11% equity. Rates are higher and lender pool is smaller.
- 95% to 100% CLTV (rare): Available from credit unions and specialty lenders. Significantly higher rates and stricter credit.
Other Things Lenders Check
Equity is the first test, but it is not the only test. Most HELOC lenders also look at:
- Credit score. Usually 620 minimum, 680 standard, 720+ for the best rates
- Debt-to-income ratio. Usually 43% or lower
- Income. Steady employment with documented earnings
- Payment history. Clean recent payment record on your existing mortgage
If your credit is lower than 620, your options narrow. Borrowers in this group should explore HELOC options for borrowers with credit challenges before applying with mainstream lenders.
How to Find Your Available Equity
You can estimate your available equity in three quick steps:
- Look up your home’s value using a recent appraisal or a comparable sale on Zillow or Redfin.
- Find your current mortgage balance from your most recent mortgage statement.
- Apply the lender’s CLTV formula to see how much HELOC you may qualify for.
Lenders verify the value with their own appraisal during the application process.
When You Do Not Have Enough Equity
If you do not yet have 15% to 20% equity, you have a few choices:
- Wait for your home to gain value through normal appreciation
- Pay down your existing mortgage to build equity faster
- Consider a fixed-rate home equity loan instead, which may have different LTV thresholds
- Look at a cash-out refinance if your current first mortgage rate is at or above current market rates
For homeowners who want a fixed payment, fixed-rate home equity loan alternatives to a HELOC compares the two product types.
Bottom Line on LTV and HELOCS
Most lenders want you to have at least 15% to 20% equity in your home before they approve a HELOC, which keeps your combined loan-to-value at or below 80% to 85%. Calculate your available equity with a quick value-minus-balance math check, compare lenders to find the highest CLTV you qualify for, and confirm credit score and DTI also fit the program. The right HELOC depends on your full financial picture, not just your equity.

FAQ on HELOCs and Equity Requirements
What is the minimum equity I need for a HELOC in 2026?
Most HELOC lenders in 2026 require a minimum of 15% to 20% equity in your home, which means your combined loan-to-value (first mortgage plus HELOC) cannot go above 80% to 85% of your home’s appraised value. Some specialty lenders stretch to 90% or even 100% CLTV, but these programs charge higher rates and typically require stronger credit scores. A small number of credit unions also offer high-LTV HELOC programs.
How do I figure out how much equity I have in my home?
To figure out your equity, subtract your current mortgage balance from your home’s current market value. Use a recent appraisal, a comparable sale value from Zillow or Redfin, or request a professional appraisal for the most accurate number. For example, on a $500,000 home with a $300,000 mortgage balance, you have $200,000 in equity, which equals 40% equity. Lenders verify this with their own appraisal during the application process.
Can I get a HELOC with only 10% equity in my home?
Yes, but options are limited in 2026. A few credit unions and specialty lenders offer high-CLTV HELOC programs that allow borrowing up to 90% or even 100% of home value, meaning you only need 0% to 10% equity. These programs typically require credit scores of 720 or higher, low debt-to-income ratios, and charge higher interest rates. Most mainstream lenders still require at least 15% to 20% remaining equity.
Does the equity requirement change for investment property HELOCs?
Yes, investment property HELOCs require more equity than HELOCs on primary residences. Most lenders cap CLTV at 70% to 75% on investment properties — meaning you need 25% to 30% equity. Pricing also runs 1% to 2% higher than primary residence HELOCs. Some investors prefer a DSCR loan or a hard money second mortgage for investment property financing, which use different qualification rules.
