Cash-Out Refinance vs. HELOC: Which Should You Choose?
Cash-Out Refinance vs. HELOC: Which Should You Choose?
You have equity. Now you need to access it. A cash-out refinance replaces your entire mortgage. A HELOC adds a credit line on top of it. Here’s how to choose the right tool for your situation.
The Core Difference
Both products let you tap home equity, but they work in fundamentally different ways:
- Cash-out refinance: You replace your existing mortgage with a new, larger mortgage. The difference is paid to you in cash at closing. You have one loan, one payment, at a fixed or adjustable rate.
- HELOC (Home Equity Line of Credit): You keep your existing mortgage and add a second lien — a revolving credit line. You draw from it as needed, pay interest only on what you use during the draw period, then repay over the repayment period.
Quick rule of thumb: If you have a low-rate first mortgage you don’t want to disturb, use a HELOC. If rates are similar to or lower than your current rate, a cash-out refi may make more sense — especially for large lump-sum needs.
How a Cash-Out Refinance Works
In a cash-out refinance, you take out a new mortgage for more than you currently owe. The difference between your new loan amount and your existing balance — minus closing costs — is paid to you at closing.
Example: You owe $250,000 on a home worth $450,000. You refinance to $330,000. After paying off the original $250,000 and closing costs (~$7,000), you receive roughly $73,000 in cash.
Key features:
- Fixed interest rate available (stable payment)
- Replaces your existing mortgage and rate
- Closing costs typically 2–3% of new loan amount
- Most lenders allow up to 80% LTV (some go to 90%)
- Proceeds can be used for anything — home improvement, debt consolidation, investment

How a HELOC Works
A HELOC is a revolving credit line secured by your home, similar to a credit card but with much lower rates. It has two phases:
- Draw period: Typically 10 years. You can draw from the line as needed. Most HELOCs are interest-only during this period.
- Repayment period: Typically 10–20 years. The line closes and you repay the outstanding balance through amortized payments.
Key features:
- Variable interest rate (tied to Prime Rate, currently 6.75% in June 2026)
- You only pay interest on what you actually draw
- Lower closing costs than a full refinance
- Flexible — draw what you need, when you need it
- Preserves your existing first mortgage and rate
Our HELOC calculator can model payment scenarios for your specific draw amount and timeline.
The Rate Environment Factor
This is the most important variable in 2026:
If you have a mortgage at 3–4% (from 2020–2021), a cash-out refinance would replace that rate with today’s rates (near 7%). Even if you need $100,000, replacing a $300,000 mortgage at 3.5% with a $400,000 mortgage at 7% dramatically increases your monthly payment and total interest cost.
In this scenario, a HELOC almost always wins — you preserve the low-rate first mortgage and only pay the higher HELOC rate on the $100,000 you need.
Conversely, if your current rate is already near today’s market rates, a cash-out refi may be competitive — you get a fixed rate on the total balance and simplify to one payment.
Side-by-Side Comparison
| Factor | Cash-Out Refinance | HELOC |
|---|---|---|
| Loan structure | Replaces existing mortgage | Second lien on top of first mortgage |
| Interest rate | Fixed or adjustable | Variable (tied to Prime) |
| Closing costs | 2–3% of new loan | Lower (often $500–$2,500) |
| Disbursement | Lump sum at closing | Draw as needed over 10 years |
| Best for | Large lump-sum needs; rate is competitive | Flexibility; protecting low first mortgage rate |
| Risk | Higher payment if rate rises | Variable rate exposure; balloon payment risk |
When a Cash-Out Refinance Wins
- Your current mortgage rate is at or above today’s rates
- You want a fixed rate on the full balance for payment certainty
- You need a large lump sum ($150,000+) and want to simplify to one payment
- You plan to stay in the home long enough to recoup closing costs
- You want to consolidate high-interest debt into a single fixed payment
When a HELOC Wins
- You have a below-market first mortgage rate you don’t want to lose
- You need flexibility — drawing money over time rather than all at once
- Your need is temporary — a project you’ll complete and then pay down
- You want lower upfront costs
- You’re not sure of the exact amount you’ll need
Tax Considerations
Interest on home equity debt (both cash-out refi and HELOC) is tax-deductible only when used to “buy, build, or substantially improve” the home securing the loan. Using proceeds for debt consolidation, vacations, or investments does not qualify for the mortgage interest deduction. Consult a tax professional for your specific situation.
The Bottom Line
For most homeowners with pre-2023 mortgages at 3–5%, a HELOC is the smarter play in today’s rate environment — it lets you access equity without disturbing a rate you can’t get back. For homeowners who bought or refinanced at current rates, a cash-out refi may be competitive depending on the amount needed.
