Cash-out refinance vs HELOC: Which builds equity faster?

Updated July 2026 · 11-minute read · Reviewed by a licensed loan officer

If you've built equity in your home, you can borrow against it with a cash-out refinance or a home equity line of credit (HELOC). Both let you tap your home's value, but they work very differently. This shows how to choose the right option for your situation in 2026.

Quick comparison: Cash-out refi vs HELOC

What is a cash-out refinance?

A cash-out refinance replaces your current mortgage with a new, larger mortgage. You pay off your existing loan and take the difference in cash. For example, if you owe $200,000 on a $400,000 home, you could refinance for $320,000, pay off the $200,000, and pocket $120,000 in cash.

✅ Choose cash-out refi if:

• You want a lower interest rate. Cash-out refis typically have lower rates than HELOCs (6.5-7.5% vs 7.5-9.5%).
• You need a large lump sum. You're doing a major renovation, consolidating debt, or paying for college.
• You want a fixed payment. Cash-out refis have fixed rates and payments, so your budget won't be disrupted by rising interest rates.
• You're okay with resetting your loan term. You'll start over with a new 15-30 year mortgage, which could mean paying more interest over time.
• You want to build equity faster. A shorter loan term (15 years) can help you build equity faster than a HELOC's interest-only period.

❌ Avoid cash-out refi if:

• You have a low rate on your current mortgage. If you locked in a 3-4% rate in 2020-2021, refinancing at 6.5-7.5% will cost you more in interest.
• You don't want to pay closing costs. Cash-out refis have 2-5% closing costs ($6,000-$15,000 on a $300,000 loan).
• You need flexibility. Cash-out refis give you all the money at once, you can't draw more later.
• You're close to paying off your mortgage. Resetting the clock with a new 30-year loan could cost you tens of thousands in extra interest.

What is a HELOC?

A HELOC (Home Equity Line of Credit) is a second loan that gives you a revolving line of credit secured by your home equity. It works like a credit card: you have a credit limit, you can borrow as needed, and you only pay interest on what you've borrowed.

✅ Choose HELOC if:

• You want to keep your current mortgage. A HELOC is a second loan, so you don't have to refinance your existing mortgage (and lose a low rate).
• You need flexibility. You can draw funds as needed during the draw period (typically 10 years), and only pay interest on what you've borrowed.
• You have ongoing expenses. Home renovation projects that span months, college tuition paid over several years, or emergency funds for unexpected costs.
• You want to avoid closing costs. Many HELOCs have no closing costs, or very low costs ($0-$500).
• You expect interest rates to drop. HELOCs have variable rates, so if the Fed cuts rates, your payments decrease.

❌ Avoid HELOC if:

• You want a fixed payment. HELOCs have variable rates, so your payment can increase if interest rates rise.
• You need a large lump sum. HELOCs are designed for ongoing draws, not one-time expenses.
• You want to build equity fast. HELOCs have interest-only payments during the draw period, so you're not building equity.
• You're a disciplined borrower. The revolving nature can tempt you to keep borrowing, leading to a cycle of debt.

Cash-out refi vs HELOC: Cost comparison

Let's compare the real cost of borrowing $100,000 with each option:

Cash-out refinance

• Loan amount: $100,000 (in addition to existing mortgage)
• Interest rate: 7.0% fixed
• Term: 30 years
• Closing costs: $5,000 (2-5% of loan)
• Monthly payment: $665 (principal + interest)
• Total interest paid over 30 years: $139,400
• Total cost: $144,400 ($139,400 + $5,000 closing costs)

HELOC

• Credit limit: $100,000
• Interest rate: 8.5% variable (starts at 8.5%, could go up or down)
• Draw period: 10 years (interest-only payments)
• Repayment period: 10 years (principal + interest)
• Closing costs: $0 (no closing costs)
• Monthly payment (draw period): $708 (interest-only on $100,000)
• Monthly payment (repayment period): $1,090 (principal + interest over 10 years)
• Total interest paid over 20 years: $108,000 (if rates stay at 8.5%)
• Total cost: $108,000

Result: The HELOC saves you $36,400 over 20 years, but your payment jumps from $708 to $1,090 after the draw period. If you can afford the higher payment and rates don't increase significantly, the HELOC is cheaper. If you want payment stability and don't mind paying more, the cash-out refi is better.

How each option affects your equity

Cash-out refinance

• Reduces equity immediately. You're borrowing against your equity, so your home equity drops by the cash-out amount.
• Builds equity over time. Each payment goes toward principal and interest, so you're building equity with every payment.
• Resets the clock. If you refinance into a new 30-year loan, you're starting over. It will take 30 years to build full equity again.

HELOC

• Reduces equity as you draw. Each time you draw funds, your equity drops by that amount.
• Doesn't build equity during draw period. Interest-only payments mean you're not paying down principal, so you're not building equity.
• Builds equity during repayment period. Once the draw period ends, you start paying principal + interest, and you build equity again.

Bottom line: A cash-out refi builds equity faster because you're paying principal from day one. A HELOC delays equity building until the repayment period (after 10 years).

When to choose each option

Scenario 1: Major home renovation ($100,000)

Best choice: Cash-out refi if you want a fixed rate and can afford closing costs. HELOC if the renovation will take 6-12 months and you want to draw funds as needed.

Scenario 2: Debt consolidation ($50,000)

Best choice: Cash-out refi if you want a fixed payment and can afford closing costs. HELOC if you want to avoid closing costs and are disciplined enough to pay off the debt quickly.

Scenario 3: College tuition ($30,000/year for 4 years)

Best choice: HELOC. You can draw $30,000 each year as tuition is due, and only pay interest on the outstanding balance during the draw period.

Scenario 4: Emergency fund

Best choice: HELOC. Open a line of credit and don't use it unless needed. You only pay interest on what you borrow, and it's there when you need it.

Can you combine both?

Yes. Some borrowers use a cash-out refi for a large, one-time expense (like a major renovation) and a HELOC for ongoing expenses (like college tuition). However, this means you'll have two loans to manage, and you'll be paying interest on both.

Frequently asked questions

Bottom line

Choose cash-out refi if: you want a lower fixed rate, need a large lump sum, and can afford closing costs. Cash-out refis build equity faster and offer payment stability, but they reset your loan term and have higher upfront costs.

Choose HELOC if: you want to keep your current mortgage, need flexibility, or have ongoing expenses. HELOCs have lower (or no) closing costs and let you draw funds as needed, but they have variable rates and don't build equity during the draw period.
