Cash Out Refi vs. HELOC: The Best Tool to Pay Off High-Interest Debt

Sagewise Editorial

Writer & Blogger

For many seniors, access to home equity isn’t about funding a luxury remodel; it’s about solving a problem: high-interest debt. A medical bill, credit card balances, or a lingering car loan can quickly drain a fixed income.

Using your home equity is a smart way to clear that expensive debt and replace it with a lower-interest, tax-advantageous loan.

The two best tools for this job are the Cash-Out Refinance and the Home Equity Line of Credit (HELOC). They are built for entirely different repayment styles. Choosing the wrong one can cost you thousands in hidden interest or fees.

As your trusted advocate, we will provide an honest, strategic guide to help you decide if you need Fixed Rate Security or Flexible Access.

Key Takeaways

  • Fixed vs. Variable: The core choice is between the stable, fixed rate of a Refi and the lower, variable interest rate of a HELOC.
  • Refi is for Security: Best when you want to lock in a new, lower mortgage rate and eliminate the risk of future interest rate hikes.
  • HELOC is for Flexibility: Best when you want low upfront fees and plan to pay off the debt quickly.
  • The Goal: Use your equity to pay off high-interest credit card debt (which can be 18-30% interest) and replace it with a low-single-digit interest rate.

Tool 1: The Cash-Out Refinance (Fixed Rate Security)

A Cash-Out Refinance replaces your existing mortgage with a new, larger one. The difference is paid to you in a lump sum.

Pros (The Security Wins):

  • Fixed Rate Protection: This is the biggest advantage. Your new monthly payment is stable, and you are 100% protected if interest rates rise over the next 15-30 years.
  • Debt Consolidation: Provides one clean, large lump sum to pay off all high-interest debt immediately.

Cons (The Cost and Time):

  • High Closing Costs: You must pay new closing costs, title fees, and appraisal fees (often $3,000 to $6,000), even though you are only taking cash out.
  • Extends Debt Repayment: You are trading short-term debt (credit cards) for long-term debt (a mortgage), potentially extending the repayment period of that debt for decades.
Loan Type
HELOC: COMoney Received is Tax-Free Because...NS
Interest Paid is Potentially Deductible?
HELOC
It is a loan that must eventually be repaid.
YES, but only if the funds are used to substantially buy, build, or improve your home.
Cash-Out Refinance
It is a loan that must eventually be repaid.
YES, but only if the funds are used to substantially buy, build, or improve your home.
Reverse Mortgage (HECM)
It is a loan advance against your equity that must be repaid (upon moving/death).
NO, because you do not pay the interest until the loan is due.

Tool 2: The Home Equity Line of Credit (HELOC)

A HELOC is a flexible line of credit you draw from as needed, secured by your home.

Pros (The Flexibility Wins):

  • Low Upfront Cost: Many lenders (especially credit unions) offer HELOCs with minimal or zero closing costs up front.
  • Pay-as-You-Go: You only pay interest on the money you actually use, making it ideal for managing unexpected medical bills or home repairs.
  • Tax Advantage: If you use the cash for home improvements, the interest paid is often deductible.

Cons (The Major Risk):

  • Variable Rate Risk: This is the primary danger. If the Federal Reserve raises interest rates, your monthly HELOC payment will increase immediately and unexpectedly.
  • Foreclosure Risk: Like all home equity loans, failure to make the minimum required payment can put your home at risk.

HELOC Warning: The "Interest-Only" Trap

A HELOC is often sold with a low payment because, during the first 5-10 years (the draw period), you may only be paying the interest.

  • The Problem: When the draw period ends, the loan shifts to the repayment phase, and you must start paying back the principal and interest. This can cause your monthly payment to triple or quadruple overnight.
  • The Strategy: Always know your repayment start date and what your maximum future payment will be. Do not assume your payment will stay low forever.

Actionable Guide: Which Tool Is Best for My Debt?

The smartest choice depends on your ability to pay off the debt quickly.

If Your Financial Situation Is...
The Recommended Tool Is...
The Strategic Reason Why
I have $40k in debt, and I need the lowest fixed monthly payment possible.
Cash-Out Refinance
Security wins. You lock in a new, low fixed rate and eliminate the risk of future interest rate hikes.
I have $15k in debt, and I can pay off $500/month.
HELOC
Flexibility wins. Since you can repay the debt quickly (in 3 years), you minimize the risk of the variable rate rising substantially, and you save thousands on closing costs.
I want a line of credit for medical emergencies, not debt payoff.
HELOC
The pay-as-you-go structure is perfect for an emergency fund, as you only pay interest when you use the cash.

The Final Step: The Debt Consolidation Strategy

No matter which loan you choose, the debt payoff strategy is simple:

  1. Clear the Debt: Use the loan proceeds (lump sum or HELOC draw) to immediately pay off all your high-interest credit card debt.
  2. Destroy the Cards: To prevent falling back into the debt trap, destroy the cards.
  3. Focus on the New Payment: Dedicate the cash flow you previously used for high-interest credit card bills entirely to paying off your new, low-interest mortgage or HELOC. This is the fastest way to become debt-free.

Frequently Asked Questions (FAQ)

A HELOC is usually faster, often closing in 3-4 weeks. A Cash-Out Refinance requires a full new underwriting process and often takes 4-8 weeks.

No. Be skeptical of “zero-cost HELOCs.” While the origination fee is often waived, you will still typically pay for the required home appraisal and title search (around $500–$1,500).

  1. A Reverse Mortgage requires that any existing liens (like a HELOC) be paid off in full first. If you still have a balance on your HELOC when you apply for a Reverse Mortgage, the HECM proceeds must be used to clear that balance.

No. The IRS (Internal Revenue Service) allows you to deduct home equity interest ONLY if the funds were used to buy, build, or substantially improve the home. Using the funds to pay off credit cards is NOT a deductible expense.

The greatest risk is the cost of the transaction. You pay high closing fees (up to $6,000) for the loan. If you plan to move within a few years, those closing costs will wipe out any savings you gained.
