HELOC vs Cash-Out Refinance: Which Saves More Money?

Homeowners seeking to tap accumulated home equity face a critical dilemma: should you take out a Home Equity Line of Credit (HELOC) as a subordinate second lien, or replace your entire first mortgage with a Cash-Out Refinance?

The Cost of Resetting a Low-Rate Mortgage

Over 80% of US mortgage holders enjoy fixed interest rates below 4.5%. Executing a cash-out refinance replaces your existing low-rate loan with a brand-new loan at today's prevailing rates (6.5% to 7.5%), subjecting your entire outstanding principal to higher interest costs.

HELOC Advantages & Structure

Leaves Your 1st Mortgage Untouched: Your existing low rate continues amortizing undisturbed.
Interest Only on What You Draw: HELOC functions like a credit card with an initial 10-year draw period where payments are interest-only.
Minimal Closing Costs: HELOCs typically involve zero to minimal closing costs, whereas cash-out refinances incur 2% to 4% in loan origination, title, and appraisal fees.

Frequently asked questions

Is HELOC interest tax deductible?

Under the Tax Cuts and Jobs Act, HELOC interest is tax-deductible ONLY if the borrowed funds are used to buy, build, or substantially improve the residence that secures the loan. Using HELOC funds for personal debts or car purchases is NOT tax-deductible.

What is the difference between a HELOC and a Home Equity Loan?

A HELOC is a revolving variable-rate line of credit. A Home Equity Loan is a fixed-rate second mortgage disbursed as a lump sum with predictable monthly payments.

How much equity can I borrow with a HELOC?

Most lenders permit a maximum combined loan-to-value (CLTV) ratio of 80% to 85% of your home's appraised value.
