A cash-out refinance replaces your first mortgage with a larger one and wires the difference. A HELOC leaves the first mortgage in place and adds a second lien you can draw. Payment, rate risk, and tax questions are not the same. Snapshot as of 2026-08. This is not tax advice and not a recommendation to take cash out.
HELOC vs cash-out: which structure are you actually comparing?
Both tap equity. They do not have the same payment, lien position, or tax questions. This is education, not a recommendation to take cash out.
| Question | Cash-out refinance | HELOC |
|---|---|---|
| Payment shape | One new first-lien payment replaces the old mortgage. Closing costs are usually financed or paid at closing. | The first mortgage stays. The line is a second payment (often interest-only in the draw period, then amortizing). |
| Lien position | Single first lien after closing. The old loan is paid off. | Second lien behind the existing first. Default risk and pricing follow that structure. |
| Rate structure | Usually a new fixed or ARM first mortgage. You re-spread closing costs over the new term. | Many HELOCs are variable after a draw period. Payment can rise without a refinance. |
| Tax questions (not tax advice) | Interest deductibility and whether cash-out is used for home improvement vs other purposes is a CPA question. This table is not tax advice. | HELOC interest deductibility also depends on use of funds and current tax law. Ask a tax professional. This is not tax advice. |
| When people compare it | You also want a new first-lien rate or term, or you need a lump sum large enough that a second lien would be awkward. | Your first-lien rate is worth keeping, the need is staged (draws over time), or you want to avoid resetting a 30-year clock. |
| Closing friction | Full mortgage close: appraisal, title, disclosures, three-day TRID wait on most files. | Usually lighter than a first-lien refinance, still an appraisal/valuation and title work. Not “no closing.” |

Decision framework
- Keep a low first-lien rate, need draws over time. HELOC is usually the comparison. HELOC overview.
- Want one payment and a new first-lien rate or term. Cash-out (or rate-and-term if you do not need cash). Cash-out.
- Need a lump sum larger than a comfortable second lien. Cash-out LTV overlays still apply.
If the goal is a lower rate without cash, that is break-even math, not this comparison.
