How Much Equity Do You Need for a HELOC?

You need enough equity so that your first mortgage balance plus the new HELOC will not exceed 80 to 85 percent of your home's current appraised value. This ceiling is called the combined loan-to-value ratio, or CLTV.

To find your available equity, start with your home's current market value. Subtract your remaining mortgage balance.

Lenders order a professional appraisal or use an automated valuation model to establish your home's current market value. They do not rely on your purchase price, your tax assessment, or online estimates.

Your equity is the appraised value minus all liens against the property. The first mortgage is the largest lien, but if you have a second mortgage, a PACE loan for energy upgrades, or a tax lien, those amounts also reduce available equity.

The combined loan-to-value ratio is the sum of your first mortgage and your HELOC, divided by your home's appraised value, expressed as a percentage. A CLTV of 80 percent means lenders will let total debt reach four-fifths of your home's worth.

A lower CLTV improves your approval odds and usually unlocks better interest rates. Borrowers who keep their CLTV at or below 70 percent often receive rate discounts of 0.25 to 0.50 percentage points because they present less risk.

Lenders tier their equity requirements by credit profile. Borrowers with FICO scores above 740 can often access 85 percent CLTV with standard documentation.

A higher credit score also expands the pool of lenders willing to compete for your business, which can mean lower closing costs and more flexible draw periods. If your score sits near a threshold—say, 678—paying down revolving credit card balances or disputing errors on your credit report can push you into the next tier and unlock thousands of dollars in additional borrowing capacity.

Twenty percent total equity puts you at the entry threshold for most HELOC programs, but approval is not automatic. Lenders also evaluate income stability, employment history, property type, and occupancy status.

Investment properties and vacation homes often require 25 to 30 percent equity and a CLTV no higher than 75 percent. Condominiums may need an extra equity cushion if the homeowners association has delinquency issues or pending litigation, because those factors increase lender risk.

When your equity falls short, you have three main alternatives. A cash-out refinance replaces your existing mortgage with a larger loan, allowing you to pocket the difference.

A personal loan requires no home equity and can close in days, but interest rates typically range from 8 to 18 percent for borrowers with good credit, well above HELOC rates. Personal loans also carry fixed monthly payments and shorter terms—usually three to seven years—so the monthly cost is higher for the same borrowed amount.

Building equity takes time. Principal reduction on a 30-year mortgage is slow in the early years; most of each payment goes to interest.

If your equity barely clears the lender's minimum, a small shift in home values or a lower appraisal can derail the application or force you to accept a much smaller credit line than you planned. Waiting six to 12 months to pay down more principal or to benefit from seasonal price appreciation can expand your borrowing power and improve your rate.

Tax considerations can influence timing as well. Interest on a HELOC is deductible only if you use the funds to buy, build, or substantially improve the home securing the loan, and only up to $750,000 in total acquisition debt for loans originated after December 15, 2017.

Finally, if you anticipate selling the home within two to three years, opening a HELOC adds closing costs—typically $500 to $2,000 in appraisal, title, and recording fees—that you will not recoup. In that scenario, a zero-closing-cost personal loan or a 0 percent introductory APR credit card for smaller amounts may prove cheaper.

How is equity calculated when applying for a HELOC?

Can you get a HELOC with only 10 percent equity?

Most mainstream lenders require at least 15 to 20 percent equity to remain after opening the HELOC, so 10 percent total equity will not qualify. Specialty lenders occasionally offer programs at 90 percent CLTV, but rates and fees are significantly higher.

Does the equity requirement differ for a condo versus a single-family home?

Yes. Condominiums often require an additional 5 percent equity cushion because lenders face added risk from homeowners association finances, special assessments, and resale restrictions.

How does a recent appraisal affect how much you can borrow with a HELOC?

What if your home value has dropped since you bought it?

If your home is worth less than your purchase price and your mortgage balance exceeds 80 percent of current value, you will not have enough equity to qualify for a HELOC. You would need to pay down the mortgage, wait for appreciation, or explore unsecured financing.

Can you use gift funds or a cash deposit to create equity for a HELOC?

Lenders require seasoning for any large deposit or paydown that artificially inflates equity. Typically, funds must be in your account and applied to the mortgage for at least six to 12 months before they count toward HELOC equity calculations.
