Getting a HELOC in Texas in 2026: The 80% Rule, Minimum Draws, and How Texas Home Equity Lines Differ

The Rule Texans Know and the Three Rules That Decide More

A lot of homeowners I've talked with over the years believe the whole Texas home equity story comes down to one number. You can borrow up to 80% of your home's value, counting your first mortgage, and everything else works the way it does anywhere else. That belief is about a third right. The 80% cap is real, and the arithmetic is a few paragraphs down. The mechanics that actually reshape a Texas home equity line of credit live somewhere else in the same document.

Home equity lines are popular again nationally, with balances at $459 billion by the New York Fed's most recent count, and if your home is in Texas you're shopping for a version of that product that runs on its own rulebook.

Texas writes its home equity rules into the state constitution, Article XVI, Section 50. One subsection, 50(a)(6), governs every home equity loan or line secured by a homestead. Another, 50(t), stacks a second layer on top that applies only to lines of credit. Three of the rules in that second layer are the ones I'd want you to understand before you fill out an application.

I run processing at AmeriSave from Hawaii these days, but I worked out of our Plano office until it closed, and back then Texas home equity files had their own rhythm. The rhythm came from those three rules more than from the cap everyone already knows. Put together, they push a Texas line toward a few large, planned draws and away from the swipe-it-when-you-need-it use that makes lines popular elsewhere. In practice, a Texas HELOC behaves a lot like a home equity loan you're allowed to take in pieces.

Run the 80% Math First, Then Stop Fighting It

The 80% cap is the rule you've heard about, and the wording in Section 50(a)(6)(B) matters. The principal amount of the new loan or line, added to all other debt secured by your homestead, can't exceed 80% of the home's fair market value on the date it's made. The test covers the whole stack of homestead debt, so your first mortgage counts against the same ceiling as the new line.

Take an illustrative home worth $400,000. The 80% ceiling is $320,000, and that figure is the most that can be secured by the property in total. If you owe $220,000 on your first mortgage, the room left for a home equity line is $100,000. Move that balance to $250,000 and the room drops to $70,000. At a $310,000 balance, common among people who bought in the past few years, the room is $10,000, which I've rarely seen a lender set up as a line. That last case is the reason I tell people to run this number before they run anything else.

It's the same arithmetic every processor on my team at AmeriSave runs on an equity file before the file moves anywhere. You can do it in under a minute with two numbers you already have, your estimated value and your current first-mortgage balance. What you can't do is negotiate around the result. In most states a loan-to-value limit is a credit policy, and a strong credit score or a low debt-to-income ratio can sometimes buy you a higher one. In Texas the ceiling is constitutional. It's the same 80% for every lender and every homeowner, and no exception desk exists to call. Texas does hand you something in return for that rigidity: a homestead equity loan or line is without recourse for personal liability against you or your spouse unless you obtained it through actual fraud, so the home secures the debt, and that protection is a big part of why the rest of the rules are as strict as they are (Section 50(a)(6)(C)).

Every Advance Has to Be at Least $4,000

This is the rule that changes plans. Any single debit or advance under a Texas home equity line has to be at least $4,000, and the notice your lender is required to hand you before closing repeats the figure, so you'll see it in writing before you sign anything (Section 50(t)(2), echoed in the required notice at Section 50(g)(R)(2)).

Picture a kitchen remodel you'd planned to fund in stages, roughly $2,500 as each phase of work wraps up. On a line in most states you'd draw exactly what the invoice says, pay interest on that balance, and repeat as the next invoice lands. On a Texas line you can't draw $2,500. Your smallest possible advance is $4,000. Your realistic choices are to draw $4,000 and park $1,500 in checking until the next bill, or to let two invoices pile up and make one draw for both.

Either choice costs you something. Parking $1,500 of borrowed money means you're paying interest on dollars that aren't doing anything yet. Waiting means you're carrying your contractor on your own cash in between. Neither is a disaster. But the flexibility that made a line attractive in the first place, paying interest only on what you've actually used, shrinks when your draws are forced up to a $4,000 floor.

That's the simple version. The fuller picture is that the $4,000 floor changes what a Texas line is good at. A line you can only touch in $4,000 increments works well for two or three large planned expenses. It works poorly as a cash-management tool for irregular small costs. Draw $60,000 for a renovation in a single advance and the product fits. Draw the same $60,000 in twenty-four $2,500 pieces and the product fights you the whole way, because every one of those pieces sits under the minimum, and the most draws the line will allow on $60,000 is fifteen.

You Can't Draw With a Card or a Mailed Check

In many states, a home equity line comes with a card or a book of checks, and homeowners swipe it at the hardware store without a separate decision behind each charge. Texas shuts that path down. You may not use a credit card, a debit card, a solicitation check, or any similar device to obtain an advance, and an unsolicited preprinted check drawn against the line is barred as well (Section 50(t)(3)).

Every advance on a Texas line has to be a deliberate request you make and your lender processes. The line can't creep up a little at a time. It grows in $4,000 or larger steps that you asked for on purpose.

One of the first things a processor checks on any equity file is whether the plan for the money matches the shape of the product. If you'd planned around card access, that plan has to be rebuilt before closing. If you'd planned around two large draws, the no-card rule costs you nothing at all, and that's the difference between a homeowner who leaves a Texas HELOC satisfied and one who leaves frustrated.

The 80% Ceiling Keeps Working After You Close

This is where Texas departs furthest from a line of credit elsewhere. In most places a loan-to-value limit is a test you pass at origination and then forget about. In Texas the ceiling follows the account for as long as the account is open.

The most principal that can be extended under the line, added to all other debt secured by the homestead, is capped at 80% of the fair market value as of the date the line is established, and the required notice spells out what that means in practice (Section 50(t)(5), with the notice language at Section 50(g)(R)(5) and (6)). Once the outstanding balance under the line exceeds 80% of that fair market value, you can't request further advances until the balance is paid back under the threshold.

Two details in that sentence deserve a second look. The value is fixed when the line is set up, so appreciation after closing doesn't create headroom you can draw against. And the restriction doesn't close your account. The line stays open and the draw period keeps running while your ability to use it is suspended. If you're funding a project where the final phase matters most, drawing the early phases up to the ceiling can leave you unable to pay for the finish.

A piece of Texas history is worth clearing up here, because outdated guidance still circulates online. An older subsection, (t)(6), once limited additional advances to 50% of the home's value. Texas voters repealed it by constitutional amendment, the same amendment that brought the fee cap down to its current 2%, and the current constitutional text marks that subsection as repealed. If you're reading an article that still quotes a 50% draw ceiling on a Texas HELOC, it's describing law that no longer applies. The live percentage ceiling on further advances is 80%.

What the 2% Fee Cap Covers and What It Leaves Out

The fees you pay to originate, evaluate, maintain, record, insure, or service a Texas home equity loan or line are capped at 2% of the original principal amount (Section 50(a)(6)(E)). On a $100,000 line, that capped bucket is $2,000.

Several real costs sit outside the cap, and they're the ones to read closely on the fee disclosures your lender gives you before closing. The constitution excludes an appraisal performed by a third-party appraiser, a property survey performed by a state-registered or state-licensed surveyor, the state base premium for a mortgagee policy of title insurance, and a title examination report when its cost is less than that base premium. Your total cash to close is the capped bucket plus whatever those items run, and the constitution sets no dollar figure for any of them.

One more fee rule applies only to lines. Fees may be charged and collected only at the time the line is established, and no fee may be charged in connection with any individual advance, under Subsection 50(t)(4). Whatever you pay, you pay once at the front.

Twelve Days Before Closing and Three Days After

Texas builds two separate waiting periods into a home equity closing, and mixing them together is the most common calendar mistake I hear about on this product.

The first comes before closing. The loan can't close before the twelfth day after the later of two events, the date you submit your application or the date your lender delivers the required notice (Section 50(a)(6)(M)(i), with the notice itself at Section 50(g)). That notice is the written summary of your rights the constitution dictates almost word for word. The clock runs from the later event, which means a notice delivered late pushes your closing date back with it.

Where the closing happens is controlled too. A Texas home equity loan or line may close only at the office of the lender, an attorney at law, or a title company, under Section 50(a)(6)(N). The kitchen-table signing with a mobile notary that's routine in other states doesn't satisfy the requirement in Texas.

The second waiting period comes after closing. You and your spouse have the right to rescind the loan without penalty within three days after it's made, a right written into Section 50(a)(6)(Q)(viii). Federal law adds its own layer for lines of credit. The CFPB's Regulation Z, at 12 CFR 1026.15(a)(3), gives you three business days to rescind an open-end plan secured by your principal dwelling, measured from the latest of the transaction itself, delivery of your rescission notice, or delivery of all material disclosures.

The practical takeaway is a floor on the timeline. From application to usable money, a Texas home equity line carries roughly two weeks before closing and a few more days after it. Build the project schedule on that floor, and if someone promises same-week funding on a Texas homestead, ask more questions.

One Extension of Credit at a Time, and a Year Between Them

Two more rules govern how often you can do this at all, and together they explain why a Texas line deserves careful sizing upfront.

Only one Section 50(a)(6) extension of credit can be secured by your homestead at any one time, under Section 50(a)(6)(K). A Texas home equity loan, a Texas cash-out refinance, and a Texas home equity line are all extensions of credit under that same subsection, so you can't hold one alongside another. If you already have a Texas cash-out in place, opening a line means dealing with what's already there.

A timing rule stacks on top. A new Section 50(a)(6) loan or line on the same homestead can't close before the first anniversary of the closing date of the previous one, with a narrow exception tied to a declared state of emergency (Section 50(a)(6)(M)(iii)). If you closed a Texas cash-out eight months ago, a line isn't available to you for another four months no matter how much equity you've built or how clean your file looks.

The two rules stack in a way that punishes undersizing. If you open a $40,000 line, draw it, and realize six months later that the project needs $20,000 more, you have no quick path back to the well. That's why the sizing conversation belongs at the front of the process, and why the 80% math and the $4,000 floor should both be settled before you pick a number.

How I'd Decide Between the Line, the Fixed Loan, and Something Else

When somebody asks me whether to use a line or a fixed home equity loan, I work through four things, the same four my processors at AmeriSave are trained to pull from any equity file. How much are you actually borrowing. What's the money for. What do you still owe on the first mortgage. And what other debt are you carrying that a full picture has to account for. The answer comes out of those four, and the first two usually settle it.

The decisive axis is whether the money is already spent. If contractors are hired, work is underway, and bills are arriving, you're committing to amortize that balance either way, so a fixed structure with a fixed payment usually does better than a variable one. Fixed comes in two shapes, and they're different products. A cash-out refinance replaces your first mortgage with a larger one and prices off the first-mortgage market, where the 30-year fixed-rate mortgage averaged 6.76% and the 15-year averaged 6.09% in Freddie Mac's most recent weekly survey, figures that are useful as environment and useless as a quote on your own loan. A fixed home equity loan is a second lien, subordinate to your first mortgage and priced on its own terms, and it leaves that first mortgage alone. The line sits on the variable side of the comparison. Home equity lines commonly price off the prime rate, which stood at 6.75% in the Federal Reserve's most recent weekly release, plus a margin your lender sets.

If the money isn't spent yet, a line usually wins, because you only pay interest on the balance you've drawn. In Texas, apply the $4,000 floor to that logic before you commit. A line only helps you avoid financing dollars you never use if your real draws clear $4,000 apiece. If your idea of flexibility is pulling $800 for an unexpected repair, a Texas line can't deliver it, and a fixed home equity loan for the planned work plus an unsecured personal line for the small surprises will serve you better.

There's an exception worth keeping, and it's aimed at the cash-out. When the amount you need is small relative to the first mortgage, the line can win even when the money is spent. Reworking a $600,000 first mortgage through a cash-out refinance to reach $30,000 of equity rarely pencils, because you'd reprice the whole balance to access a fraction of it. At that size, the higher variable rate on a small second usually costs less than disturbing the first, and a fixed home equity loan, as a second lien itself, sits on the same side of that comparison. The bigger the amount you need, the more the math tips toward the cash-out. In Texas, remember that the cash-out, the fixed home equity loan, and the line all fall under the same Section 50(a)(6) one-at-a-time rule, so whichever you pick occupies the only slot your homestead has for at least a year. That's what makes this a one-shot choice. Pick the structure that fits the full amount, because a second pass is a year away at the earliest.

Spearheading the logic behind Scenario AI at AmeriSave, the pricing tool that runs every program and rate combination against a homeowner's full debt picture, reinforced something I'd seen on files for years. The winning structure is almost always the one that moves the monthly obligation the least. Payment shock is the outcome to minimize. Money borrowed versus money repaid is the frame that gets you there, and the headline rate is only one input.

Tax treatment belongs in the same conversation. The IRS limits the home equity interest deduction to situations where the proceeds buy, build, or substantially improve the home that secures the debt, and only on acquisition debt up to $750,000 combined, or $375,000 if you're married filing separately. Publication 936 lays out the tests. A tax professional should apply them to your return, because the answer depends on how you use the money.

Ask the Section 50(a)(6) Question on the First Call

One step belongs before all of the above. Not every lender is allowed to make this loan. Texas limits who may originate a Section 50(a)(6) extension of credit to a defined set of lender types, among them banks, credit unions, and state-regulated mortgage companies, and Section 50(a)(6)(P) carries the full list.

That restriction, stacked on top of the constitutional mechanics, is why some lenders don't offer lines on Texas homesteads at all, including some who'd happily quote you a line on a home in another state. Ask directly on the first call whether the lender originates Section 50(a)(6) lines of credit, and use that phrase, because it separates people who run this program from people who don't.

Ask direct questions early rather than politely late; the habit matters more on a Texas equity file than almost anywhere else. While you have someone on the phone, ask what the margin over the index looks like on a line your size, and ask what the appraisal, survey, and title costs outside the 2% cap are expected to run. Those two answers, plus the 80% math you've already done, tell you most of what you need to know before you spend a 12-day waiting period finding out.

The Bottom Line

A Texas home equity line is a good tool held to an unusual set of rules, and the rules push it toward large, deliberate borrowing. The $4,000 floor keeps you from nibbling at it, and the no-card rule means it can't grow in the background. On top of those, the continuing 80% ceiling stops you from drawing past the cap and expecting more. Combined, they make a Texas HELOC behave less like a revolving line you tap for small amounts and more like a lump-sum loan you're allowed to take in a few large, planned pieces.

Before you apply, run two numbers. Take 80% of what your home is worth, subtract everything secured by the property, and look honestly at whether the remainder covers what you're planning. Then ask whether the draws you actually intend to make will each clear $4,000. If both answers are yes and you're holding a first-mortgage rate you'd rather keep, a Texas line does the job well. If your draws are small and frequent, the structure will frustrate you no matter how good the pricing looks, and a fixed home equity loan or an unsecured option deserves a look instead.

The option that fits both your size and your timing is usually the one worth signing. That's the whole test.
