HELOC vs Cash-Out Refinance

TL;DR: A HELOC is a revolving credit line at variable rates. A cash-out refinance is one lump sum that replaces your entire mortgage at today's rate. Right answer depends on your current mortgage rate.

_Last reviewed: July 2026 · 4 min read_

If you have home equity you want to tap and are choosing between a HELOC and cash-out refinance, the honest answer is: if your current mortgage rate is BELOW today's rates, keep it and get a HELOC. If your current rate is ABOVE today's rates, cash-out refinance can consolidate at a better rate. The comparison usually hinges on that single question.

What's a HELOC?

A Home Equity Line of Credit is a revolving credit line secured by your home. It has:

• Variable interest rate — typically Prime + a margin (currently 8-11% in most markets)
• Draw period — 5-10 years where you can borrow, repay, reborrow
• Repayment period — 10-20 years of fixed payments after draw ends
• Interest-only payments during draw period (optional)
• Closing costs — usually $0-$500

Your first mortgage stays untouched. HELOC is a second lien.

What's a cash-out refinance?

A cash-out refinance replaces your first mortgage entirely with a new, larger mortgage — the difference paid to you in cash. It has:

• Fixed interest rate at today's market rate
• New 30-year (or 15-year) term resets your amortization clock
• Closing costs — $3,000-$6,000 typical
• Full mortgage underwriting — income, credit, appraisal

Your old mortgage is paid off; you have one new bigger mortgage.

The rate comparison that matters

Say your current mortgage is at 3.5% (locked in 2021). Today's rate is 7%.

• HELOC at 9.5%: high but only on the borrowed portion; keeps your $300K first mortgage at 3.5%
• Cash-out refi at 7%: replaces $300K at 3.5% AND $50K new borrowing with $350K at 7%

Cash-out refi costs you 3.5 percentage points on your existing $300K = $10,500/year more interest just to consolidate. Only worth it if the HELOC's higher rate on $50K exceeds that. It usually doesn't.

Conversely, if your current mortgage is at 8% and today's rate is 6%, refinancing reduces your rate on the entire balance — cash-out refi wins.

What's the tax angle?

Under IRS rules (Publication 936), interest on either option is deductible on Schedule A only if the funds are used to buy, build, or substantially improve the home securing the loan.

Using either for debt consolidation, tuition, or a car? Interest is not deductible.

Total acquisition-debt cap for post-2017 mortgages: $750,000 ($375K for MFS). See mortgage interest deduction rules for 2026.

Comparison table

| Factor | HELOC | Cash-Out Refi | |---|---|---| | Rate type | Variable | Fixed | | Rate level (2026 typical) | 8-11% | 6-7.5% | | Closing costs | $0-$500 | $3,000-$6,000 | | Impacts current mortgage | No | Yes (replaces it) | | Flexibility (borrow/repay) | High | None | | Best when current rate is | LOW | HIGH |

When each wins

HELOC wins:

• Current mortgage rate is significantly below market
• Need flexibility (draw as needed, repay to reborrow)
• Small draws ($10K-$50K)
• Uncertain if you'll use all the money

Cash-out refi wins:

• Current mortgage rate is above market
• Need large lump sum ($100K+)
• Want fixed rate certainty
• Willing to pay closing costs upfront

Frequently asked questions

Can I have both a HELOC and cash-out refi?

Yes, but rarely makes sense. Some homeowners refinance to a lower rate on the mortgage AND take out a HELOC for future flexibility.

What if I might sell in a few years?

HELOC is more flexible for short-hold. Refinance closing costs need years of savings to break even — see should I refinance if I'll move in 3 years?.

Do I have to draw the full HELOC amount?

No — that's the point. Draw what you need, when you need it. Only pay interest on drawn balance.

FAQ

How much equity do I need to qualify for a HELOC or cash-out refinance?

Most lenders require you to keep at least 15-20% equity after the loan, meaning you can borrow up to 80-85% of your home's value minus what you owe. A cash-out refinance typically caps at 80% loan-to-value, while some HELOCs allow up to 85%.

What happens to my HELOC rate if the Fed cuts rates?

Your HELOC rate will drop because it's tied to the Prime rate, which moves with Federal Reserve changes—usually within 30 days. If Prime falls 0.5%, your HELOC rate falls 0.5%, lowering your monthly payment on the outstanding balance.

Can I pay off a HELOC early without penalty?

Most HELOCs have no prepayment penalty, so you can pay down or close the line anytime during the draw period. Check your specific lender agreement—some charge an early-closure fee if you close within the first 2-3 years.

If I refinance, do I lose the remaining years of low payments on my original mortgage?

Yes—a cash-out refinance resets your loan to a new 30-year term, so even if you had 18 years left at 3.5%, you now have 30 years at the new rate. This extends how long you'll pay interest unless you make extra principal payments.

Which option is faster to close?

A HELOC typically closes in 2-3 weeks with minimal paperwork and low fees. A cash-out refinance takes 30-45 days and requires full income verification, appraisal, title work, and closing costs of $3,000-$6,000.
