Home Equity
How Much Equity Do I Need for a HELOC?
How much home equity HELOC programs typically require, why lenders keep an equity cushion, and what to do when you are close but not quite there.
Updated 2026-08-21| Applies to: Homeowners who are unsure whether they have enough equity to open a line.
The short answer
Most HELOC programs require you to keep some equity in the home after the line is in place, so the usable amount is your value multiplied by the program's maximum combined loan to value, minus what you owe. Practically, homeowners with less than roughly 10% to 20% equity often find little or no usable line, while homeowners with 25% or more equity usually have workable options.
Why lenders keep a cushion
A HELOC sits behind the first mortgage. In a forced sale, the second lien is paid only after the first is satisfied and selling costs are covered. The equity cushion is the lender's protection, which is why maximum combined loan to value exists at all.
If you are short on equity today
- Wait for principal paydown and market appreciation to close the gap
- Make a lump sum principal reduction on the first mortgage if you have the funds
- Ask whether a different program allows a higher CLTV tier at your credit score
- Consider whether the underlying need is better solved another way
Value matters as much as balance
Two homeowners with identical loan balances can get very different answers if one home has appreciated more. Recent comparable sales in your neighborhood drive the valuation, which is why an estimate from an online model is a starting point and not an answer.
General education, not a commitment to lend. HELOC availability, credit line limits, rates and closing timelines vary by lender, program, property type and current guidelines. Manny Oloyede | Mortgage Broker | NMLS 1824463 | Ultimate Mortgage Brokers LLC.
Common mistakes to avoid
- Counting improvements at their cost rather than their contributory market value
- Assuming a HELOC is impossible because a single lender said no
- Overlooking a small existing second lien that consumes the remaining room
