A Texas cash-out refinance and a HELOC both let you turn home equity into cash, but they work in almost opposite ways. A cash-out refinance replaces your entire first mortgage with a new, larger one and hands you the difference as a lump sum. A HELOC leaves your first mortgage untouched and adds a separate, flexible line of credit behind it. Which one is better depends less on which product is objectively superior and more on what your current mortgage rate looks like, how you plan to use the money, and whether you want a fixed payment or ongoing flexibility.
Here’s how each actually works, the Texas rules that apply to both, and how to think through the decision.
The Core Difference Between the Two
A Texas cash-out refinance is a single new loan. It pays off your existing mortgage and combines it with the cash you’re accessing into one new first lien, with one monthly payment.
A HELOC is a second, separate loan. Your existing mortgage stays exactly as it is, rate and all, while the HELOC sits behind it as a revolving line of credit. A HELOC allows you to draw from, repay, and draw from again during a set draw period, often 10 years.
That structural difference, one loan versus two, is what drives almost every other difference between them.

How a Texas Cash-Out Refinance Works
You refinance your current mortgage into a new, larger loan and receive the difference in cash at closing. Because it replaces your first lien entirely, your new loan carries whatever rate is available at the time of the refinance, for better or worse. Payments are fixed and predictable, typically over a standard 15 or 30-year term.
How a HELOC Works in Texas
A HELOC gives you access to a credit line, up to an approved limit, that you draw from as needed rather than receiving all at once. You only pay interest on what you’ve actually drawn, and as you repay it, that credit becomes available again during the draw period. HELOC rates are typically variable, meaning your payment can change over time as rates move.
Texas HELOCs fall under the same Article XVI, Section 50(a)(6) rules that govern Texas cash-out refinances, since a HELOC secured by your homestead is still a form of home equity lending in Texas. That means the 80% combined loan-to-value cap, the one-home-equity-loan-at-a-time rule, and the 12-day notice and 3-day rescission period all apply here too. It also means Texas HELOCs can’t include the kind of minimum-draw or minimum-balance requirements some other states allow, since Texas law protects a homeowner’s ability to pay the balance to zero at any time.
Side-by-Side Comparison
Loan structure: Cash-out refinance = one loan, replaces your first mortgage. HELOC = two loans, first mortgage stays untouched.
Funds disbursement: Cash-out refinance = lump sum at closing. HELOC = draw as needed during the draw period.
Rate type: Cash-out refinance = typically fixed. HELOC = typically variable.
Payment structure: Cash-out refinance = one fixed payment. HELOC = interest-only or variable payment during the draw period, often converting to principal-and-interest afterward.
Effect on existing mortgage rate: Cash-out refinance = replaces it entirely. HELOC = leaves it untouched.
Texas rules that apply: Both are subject to the 80% LTV cap, the 12-month rule between home equity loans, and the 12-day notice/3-day rescission period.
When a Cash-Out Refinance Tends to Make More Sense
A cash-out refinance is often the stronger fit when your current mortgage rate is higher than what’s currently available, so refinancing improves your rate and accesses equity at the same time. It also tends to fit better when you need a large, specific lump sum for something like debt consolidation or a major one-time expense, and you want the predictability of a fixed payment rather than a variable one.
When a HELOC Tends to Make More Sense
A HELOC often fits better when your current mortgage rate is meaningfully lower than today’s rates, since a cash-out refinance would mean giving that rate up on your entire loan balance just to access a portion of your equity. It also tends to fit situations where you don’t need all the money at once, like a phased renovation, or where you want the flexibility to borrow, repay, and borrow again without refinancing every time your needs change.
Texas Rules That Apply to Both
Regardless of which you choose, Texas law caps combined borrowing at 80% of your home’s value, allows only one home equity loan on your homestead at a time, requires a 12-month wait between closing one home equity loan and closing another, and guarantees a 12-day notice period before closing plus a 3-day right to cancel afterward. These protections exist specifically because Texas treats home equity borrowing, in either form, as a decision serious enough to require extra safeguards.
Common Mistakes When Choosing Between Them
The most common mistake is comparing the two purely on interest rate without accounting for what happens to your existing first mortgage. A HELOC’s higher rate on a small balance can easily cost less overall than refinancing a large, low-rate first mortgage away entirely. The second common mistake is choosing a HELOC for a large, one-time, fully-known expense, where the payment predictability of a cash-out refinance would likely serve better.
Mortgage Planner’s Perspective
Neither option is better in the abstract. What matters is your current rate, how you plan to use the funds, and whether predictability or flexibility serves your situation better. That’s the analysis worth running before choosing either one, not after.

FREQUENTLY ASKED QUESTIONS
How They Work
Q: What’s the main difference between a Texas cash-out refinance and a HELOC?
A: A cash-out refinance replaces your entire first mortgage with one new loan and gives you the difference as a lump sum. A HELOC leaves your first mortgage untouched and adds a separate, flexible line of credit behind it.
Q: Are HELOC rates always variable in Texas?
A: Typically, yes. Most HELOCs carry a variable rate, meaning your payment can change as market rates move, unlike the fixed payment structure common with a cash-out refinance.
Q: Do the same Texas rules apply to both?
A: Yes. Both fall under Texas Constitution Article XVI, Section 50(a)(6), including the 80% loan-to-value cap, the 12-month waiting period between home equity loans, and the 12-day notice and 3-day rescission requirements.
Choosing Between Them
Q: Which is better if I have a low mortgage rate already?
A: A HELOC often makes more sense in that case, since it leaves your existing low rate untouched rather than replacing your entire mortgage at a potentially higher current rate.
Q: Which is better for a large one-time expense?
A: A cash-out refinance tends to fit better for a large, known lump sum, since it offers a fixed, predictable payment rather than a variable one.
Q: Can I get a HELOC if I already have a cash-out refinance on my home?
A: Not right away. Texas law requires 12 months between closing one home equity loan, including a cash-out refinance, and closing another, such as a HELOC, on the same homestead.
