HELOC vs. Cash-Out Refinance: How to Decide
The most common refinance comparison, broken down by interest rate, equity, and cash use. The right answer changes based on your specific situation.
Both HELOCs and cash-out refinances pull equity out of your home, but they're structurally different products that fit different situations. Picking the wrong one can cost you tens of thousands over the life of the loan. Here's the framework I use when working through this decision with homeowners.
What's the actual difference between a HELOC and a cash-out refinance?
A HELOC adds a second loan on top of your existing first mortgage — your original loan stays in place untouched. A cash-out refinance replaces your existing mortgage with a new, larger one and gives you the difference in cash. The structural distinction matters because it determines what happens to your current rate, your total monthly obligation, and your closing costs.
A HELOC is also typically a variable-rate product tied to the Prime rate, while a cash-out refinance is usually a fixed-rate 30-year loan. That difference compounds over time: a HELOC payment can rise if rates rise, while a fixed-rate cash-out locks your payment in.
When does a HELOC make more sense than a cash-out refinance?
A HELOC is usually the better choice when your existing first mortgage rate is meaningfully below today's market rate. If you're sitting on a 3% mortgage from 2020-2021 and today's rates are around 6.75%, refinancing into a new 30-year loan throws away your most valuable financial asset to access equity. A HELOC lets you access the equity without disturbing the low first mortgage.
HELOCs also win on closing costs (often $1,500-$3,000 vs. $5,000-$8,000 for a refi) and on flexibility — you can draw funds as needed during the draw period rather than taking the full amount at closing. For renovations where costs unfold over time, this is a real advantage.
When does a cash-out refinance make more sense than a HELOC?
A cash-out refinance usually wins when your existing rate is at or above today's market rate, when you need a large amount of cash (typically $150,000+), or when you want the certainty of a fixed payment for the entire loan. If you're going to be paying interest on the borrowed amount for years anyway, locking the rate is often worth the higher closing costs.
Cash-out refinances also tend to be cheaper monthly when the rate environment is favorable, because the entire balance amortizes over 30 years at a fixed rate. HELOCs typically have a 10-year draw period followed by a 15-20 year repayment period, and the principal isn't amortized during the draw phase.
What about LTV (loan-to-value) limits?
Cash-out refinances on owner-occupied primary residences typically cap at 80% combined LTV for conventional loans. HELOCs can sometimes go to 85% or even 90% CLTV depending on the lender and your credit. For second homes and investment properties, both products have lower LTV caps — conventional cash-out on investment property tops out at 75%, and HELOCs on investment property are similarly restricted or unavailable.
If your equity position is tight, the HELOC's higher CLTV ceiling may be the only way to access the cash you need. If you have substantial equity (40%+), either product works and the rate math becomes the deciding factor.
How do closing costs compare between the two?
Cash-out refinances typically cost $5,000-$8,000 in closing costs on a mid-sized loan, including lender fees, title insurance, appraisal, escrow, and recording. HELOCs typically run $1,500-$3,000 in actual fees, though many lenders waive these fees as a promotion (often with a recapture clause if you close the line within 2-3 years).
The closing cost gap matters more on smaller cash-out amounts. If you're only accessing $50,000, the $5,000+ closing cost on a refinance is 10% of what you're borrowing — a huge drag on the math. On a $200,000 cash-out, the same closing cost is 2.5% — much more tolerable.
What about tax deductibility?
Under current federal tax law, interest on HELOC and cash-out funds is deductible only when the proceeds are used to buy, build, or substantially improve the home that secures the loan. Debt consolidation, education, and other personal uses don't qualify for the deduction. This applies equally to HELOCs and cash-out refinances — neither product has a structural tax advantage.
Talk to your tax advisor before making decisions based on deductibility. Tax law changes, and your individual situation determines what actually applies to you.
If your current rate is well below today's market and you need under $150,000, a HELOC is almost always the right answer. If your current rate is at or above market and you need a large fixed amount, a cash-out refinance typically wins. Run your specific numbers — the right answer depends on the gap between your current rate and today's rates, how much cash you need, and what you'll do with the funds.
