HELOC vs Cash-Out Refinance: Which Way to Tap Equity Costs Less in 2026
A HELOC gives you a revolving credit line against your equity without changing your first mortgage. A cash-out refinance replaces your existing mortgage with a larger one and gives you the difference in cash. If you have a low first mortgage rate, a HELOC preserves it. If your current rate is above market, a cash-out refi lets you access equity and improve your rate simultaneously.

HELOC Basics
- Structure: A revolving line of credit secured by your home equity — draw what you need during the draw period, pay interest only on what you use
- Rate type: Variable rate tied to prime, currently resulting in rates of 8-10% for most borrowers with good credit in 2026
- First mortgage: Your existing first mortgage stays untouched — you keep your current rate, balance, and payment schedule
- Action: Best when you have a low first mortgage rate below 5% that you do not want to refinance away
Cash-Out Refi Basics
- Structure: Replace your existing mortgage with a new, larger mortgage and receive the equity difference as cash at closing
- Rate type: Fixed rate on the new first mortgage — currently 6.25-7.0% for cash-out depending on credit, LTV, and program
- First mortgage: Your existing first mortgage is paid off and replaced — you lose your current rate and start a new amortization schedule
- Action: Best when your current rate is 6%+ and you can refinance into a similar or lower rate while accessing equity
Cost Comparison
- HELOC closing costs: Typically $0-$2,000 — many lenders waive closing costs on HELOCs, making them cheaper to open
- Cash-out refi costs: $3,000-$8,000 in closing costs — same as any mortgage refinance with origination, title, and appraisal fees
- Monthly cost: HELOC interest-only payments are lower initially but variable; cash-out refi payments are fixed but include principal
- Action: Calculate total cost over your expected use period — HELOC is cheaper short-term, cash-out refi is often cheaper long-term
Equity Limits
- HELOC CLTV: Most lenders allow combined loan-to-value up to 80-90%, meaning your first mortgage plus HELOC cannot exceed 80-90% of home value
- Cash-out LTV: Conventional cash-out max is 80% LTV, FHA cash-out max is 80% LTV, VA cash-out allows up to 90-100% LTV
- Minimum draw: HELOCs have no minimum draw — only take what you need. Cash-out refi requires a minimum cash-out amount, typically $2,000-$5,000
- Action: Calculate your available equity at 80% LTV minus your current mortgage balance — that is your maximum access under either option

The Bottom Line Up Front
If your first mortgage rate is below 5%, use a HELOC to access equity — replacing a low rate with a 6.5% cash-out refi costs more over time even though the HELOC rate is higher. If your first mortgage rate is 6%+ already, a cash-out refinance often makes more sense because you are not sacrificing a valuable low rate.
The decision hinges on one number: your current first mortgage rate. About 80% of homeowners locked rates below 5% during 2020-2022. For them, a HELOC at 8.5% on $50,000 costs less in total interest than refinancing a $300,000 mortgage from 3.5% to 6.5% just to access that same $50,000. The math changes when the amount of equity needed is large or when the first mortgage rate is already above market.
What Are the Key Differences Between a HELOC and Cash-Out Refinance?
A HELOC adds a second lien. A cash-out refinance replaces your first lien. That structural difference drives every cost, rate, and risk comparison between the two.
With a HELOC, your existing mortgage continues unchanged — same rate, same payment, same amortization schedule. The HELOC sits behind it as a separate credit line with its own rate and payment. With a cash-out refi, your old mortgage is paid off and replaced with a new, larger mortgage at today’s rates.
| Feature | HELOC | Cash-Out Refinance |
|---|---|---|
| Lien position | Second lien (behind first mortgage) | New first lien (replaces existing) |
| Rate type | Variable (prime + margin) | Fixed (30-year or 15-year) |
| Current rate range | 8-10% (2026) | 6.25-7.0% (2026 cash-out) |
| First mortgage impact | Unchanged — keep current rate | Replaced — lose current rate |
| Closing costs | $0-$2,000 | $3,000-$8,000 |
| Draw flexibility | Draw as needed during draw period | Lump sum at closing |
| Payment structure | Interest-only during draw period | Fully amortizing P&I |
| Max LTV/CLTV | 80-90% CLTV | 80% LTV (conv) / 100% (VA) |
| Tax deductibility | Home improvement use only | Home improvement use only (post-TCJA) |
Deal Math
Example: You have a $280,000 mortgage at 3.25% and need $60,000 for a kitchen renovation. Option A: HELOC at 8.75% on $60,000 = $437/month interest-only. Option B: Cash-out refi at 6.50% on $340,000 = $2,149/month P&I. With Option B, your old payment was $1,219/month at 3.25% — you now pay $930/month more to access $60,000. The HELOC costs $437/month extra on the same $60,000. The HELOC saves $493/month despite the higher rate because it does not disturb the low-rate first mortgage.
How Do Current Rates Compare Between HELOC and Cash-Out Refi?
HELOC rates are variable and currently higher — 8-10% versus 6.25-7.0% fixed on cash-out. But the HELOC rate applies only to the drawn amount, not your entire mortgage balance.
This is the most common source of confusion. A HELOC at 9% sounds worse than a cash-out refi at 6.5%. But the 9% applies to the $50,000 HELOC draw, while the 6.5% applies to the entire $350,000 new mortgage. If your existing mortgage was at 3.5%, the cash-out refi costs you 3% more on $300,000 you were not even trying to access — an additional $9,000/year in interest on the untouched portion.
- HELOC rate is higher per dollar borrowed, but the total interest cost is often lower because it applies to a smaller balance — $50,000 at 9% = $4,500/year versus replacing $300,000 at 3.5% with $350,000 at 6.5% = $12,750/year more in interest
- Cash-out refi locks in a fixed rate, eliminating variable rate risk — if prime increases, your HELOC payment rises but your cash-out refi payment stays constant
- HELOC rates will decrease if the Fed cuts rates — if you expect rate cuts in the next 2-3 years, the variable HELOC rate may come down to 6-7%, narrowing the gap further
- For large equity draws ($100,000+), cash-out refi becomes more competitive because the fixed rate advantage compounds over the larger balance and the closing cost is amortized over a larger amount
Which Option Is Better for Your Situation?
Use a HELOC when you want to preserve a low first mortgage rate and need modest equity access. Use a cash-out refi when your current rate is already at or above market and you want a lump sum with a fixed payment.
- HELOC wins when: current first mortgage rate is below 5%, equity need is under $75,000, you want flexible access (draw only what you need), or you expect rates to drop and plan to pay the HELOC down quickly
- Cash-out refi wins when: current first mortgage rate is 6%+ (so you are not sacrificing a valuable low rate), you need a large lump sum ($75,000+), you want payment certainty with a fixed rate, or you want to consolidate the first mortgage and equity access into one payment
- Consider both when: current rate is 5-6% — this is the crossover zone where the math depends on draw amount, hold period, and rate trajectory expectations
- Third option: A fixed-rate home equity loan (second lien, fixed rate, lump sum) can be the middle ground — fixed rate like a cash-out refi but second lien like a HELOC, preserving your first mortgage
Lender Reality Check
Some lenders will not approve a HELOC if your combined loan-to-value exceeds 80%. If your first mortgage balance is already near 80% LTV, your available HELOC draw may be minimal or zero. In that case, a cash-out refi may be your only option to access equity — even if it means replacing a low rate. Run the CLTV math before applying for a HELOC to confirm there is enough equity headroom to make it worthwhile.
What Are the Risks of Each Option?
Both options use your home as collateral. The primary risks differ by structure: HELOC carries rate risk, cash-out refi carries amortization reset risk.
- HELOC variable rate risk — if prime increases by 2%, your HELOC rate increases by 2%, potentially adding hundreds per month to your payment with no ceiling protection on most products
- HELOC repayment period shock — after the 10-year draw period ends, the HELOC converts to fully amortizing repayment over 15-20 years, which can double or triple the monthly payment
- Cash-out refi amortization reset — replacing a mortgage you have been paying for 10 years with a new 30-year resets your payoff clock, meaning you pay interest for 40 years total instead of 30
- Cash-out refi rate risk (upward) — if you replace a 3.5% mortgage with a 6.5% cash-out and rates drop to 4.5% next year, you are stuck with 6.5% until you can refinance again at additional cost
The Bottom Line
The HELOC vs cash-out refinance decision comes down to your current first mortgage rate. Below 5%, protect it with a HELOC. Above 6%, a cash-out refi makes sense because you are not sacrificing much. Between 5-6%, run the numbers both ways.
Get quotes for both a HELOC and a cash-out refinance. Calculate total monthly cost under each option for the amount of equity you need. Factor in closing costs, rate variability, and how long you plan to carry the debt. The right answer is the one that costs you the least over your expected timeline — and that answer is different for every borrower depending on their existing mortgage rate.
Frequently Asked Questions
Can I get a HELOC right after buying a house?
Most lenders require a seasoning period of 3-12 months after purchase before approving a HELOC. Some lenders allow immediate HELOC origination at closing, but these are less common. Cash-out refinance seasoning is typically 6-12 months for conventional and 6 months for FHA loans.
What credit score do I need for a HELOC?
Most HELOC lenders require 680-700 minimum FICO. Some go as low as 620 with higher rates and lower CLTV limits. Cash-out refinance is available at 620+ through conventional and 580+ through FHA. If your credit score is below 680, cash-out refi may be easier to qualify for.
Can I pay off a HELOC early?
Yes. Most HELOCs have no prepayment penalty. You can pay down or pay off the balance at any time without fees. Some HELOCs charge an early termination fee (typically $300-$500) if you close the line within 2-3 years of opening. Check the terms before signing.
Will a HELOC affect my ability to get a new mortgage?
Yes. An open HELOC — even if unused — may be counted as a monthly obligation by a new mortgage lender. Some lenders count 1% of the credit limit as a monthly payment for DTI purposes. If you plan to buy another property, the HELOC may reduce your qualifying power even if you have not drawn on it.
Can I convert my HELOC to a fixed rate?
Some HELOC products offer a fixed-rate conversion option that lets you lock a portion of your balance at a fixed rate. This gives you the flexibility of a HELOC with the payment certainty of a fixed rate on the amount you have drawn. Not all HELOCs include this feature — ask before you apply.
Is a home equity loan different from both HELOC and cash-out refi?
Yes. A home equity loan is a fixed-rate, lump-sum second lien — it combines the second-lien position of a HELOC (preserving your first mortgage) with the fixed rate and lump sum of a cash-out refi. It can be the best of both worlds for borrowers who want to preserve a low first mortgage rate but prefer a fixed payment over a variable HELOC.
