5 HELOC Myths Austin Homeowners Still Believe in 2026
Austin homeowners are sitting on a lot of paper wealth. The median sold price across the Austin area was $445,000 in Team Price Real Estate’s July 23, 2026 market report, and a large share of local owners bought before 2022 with mortgage rates in the 3s and 4s. That combination makes a HELOC (home equity line of credit) look like the obvious way to reach that equity without touching a low first-mortgage rate, and banks advertise them constantly. Here is the problem: Texas treats home equity borrowing differently than any other state, and much of the HELOC advice repeated online simply does not apply here. These five myths are the ones we hear most often from Austin homeowners, along with what actually happens when you borrow against a Texas homestead.
Key points:
- Texas caps all debt against your primary home at 80 percent of its market value, and that includes a HELOC.
- Texas requires a waiting period of at least 12 days between your home equity application and closing.
- On a $445,000 Austin home with $250,000 still owed, the realistic borrowing ceiling is about $106,000, well below the $195,000 of raw equity.
- Most HELOCs carry a variable rate, and the payment can jump when the draw period ends.
- A second lien can complicate a future refinance, even if the line balance is zero.
- Mortgage Austin does not originate HELOCs; sometimes a conventional cash-out refinance is the better tool, and sometimes the HELOC honestly wins.
How does a HELOC actually work in Texas?
A HELOC is a revolving credit line secured by your home as a second lien. In Texas, total debt against your primary residence cannot exceed 80 percent of its market value, you must wait at least 12 days after applying before you can close, and you can generally take out only one home equity loan in any 12-month period. Most lines offer a draw period of about 10 years, followed by a repayment period of 10 to 20 years.
During the draw period you borrow what you need, when you need it, and many lenders require only interest payments on the amount drawn. When the draw period ends, the line converts to a repayment schedule that includes principal, which is where many borrowers get an unwelcome surprise. Nearly all HELOCs use a variable rate tied to the prime rate, so the cost of what you borrowed can move up or down over the years you hold the line.
Those are the mechanics. Now for the myths.
Myth 1: A HELOC works the same in Texas as it does in other states
Texas has the strictest home equity rules in the country, written directly into the state constitution (Article XVI, Section 50). If you moved here from another state, most of what you knew about borrowing against a house needs an update.
The big differences: your combined mortgage debt cannot exceed 80 percent of the home’s value, while many other states allow 90 percent or more. You must wait at least 12 days after submitting your application before closing. The closing itself has to happen at the office of a lender, attorney, or title company, never at your kitchen table. And once you take out a home equity loan, you generally cannot take out another one against the same home for 12 months.
These rules exist because Texas has a long tradition of protecting the homestead from creditors. They slow the process down, and they also make it much harder to borrow your way into losing the house.
Myth 2: A HELOC is the cheapest way to borrow against your home
A HELOC is often the cheapest way to open access to your equity. Whether it stays cheap depends on rates and on how you use it.
Three costs catch borrowers off guard. First, the variable rate: when the prime rate rises, your HELOC rate rises with it, usually the very next billing cycle. Second, promotional pricing: many lines advertise a low introductory rate that expires after 6 to 12 months. Third, the payment jump at the end of the draw period: going from interest-only payments to full principal-and-interest amortization can raise the monthly bill substantially even if rates never move.
A HELOC used for a short-term need and paid off quickly can cost very little. The same line carried at a high balance for 15 years can cost far more than a fixed-rate alternative. Run the math on your actual plan, and if you want a second set of eyes on it, that is a conversation we have with Austin homeowners all the time.
Myth 3: You can borrow against all of your equity
The 80 percent combined cap does the real gatekeeping here, and the math surprises people. Take a home worth $445,000, the Austin-area median in Team Price’s July 23, 2026 report, with $250,000 left on the mortgage. On paper that owner has $195,000 of equity. The Texas ceiling is 80 percent of $445,000, which is $356,000 of total allowed debt. Subtract the $250,000 first mortgage and the maximum available through any home equity product is about $106,000.
Individual lenders can be more conservative than the constitutional cap, and many are. Credit score, income, and the appraised value they assign all shape the final line amount. Treat 80 percent as the best case, subject to credit, income, and property qualification, never the starting point.
Myth 4: A HELOC will not affect your future mortgage plans
A HELOC is a lien on your home, and it stays one until the line is closed, even when the balance is zero.
If you refinance your first mortgage later, the HELOC lender must either be paid off or agree to resubordinate, which means formally accepting second position behind the new loan. Subordination requests add time to a refinance and lenders can decline them. Underwriters also count the HELOC in your numbers twice: the payment lands in your DTI (debt-to-income ratio, the share of monthly income going to debt), and the full line amount can factor into combined loan-to-value limits on the new loan.
None of this makes a HELOC a mistake. It does mean the line should fit your longer plan. If you expect to refinance or move within a couple of years, open the line with that in mind.
Myth 5: A HELOC is your only option besides selling
Texas homeowners have two other main paths to their equity, and both live under the same 80 percent rules.
A home equity loan (a fixed-rate lump sum, sometimes called a second-lien term loan) trades the HELOC’s flexibility for a rate and payment that never change. A cash-out refinance replaces your first mortgage entirely with a larger loan and hands you the difference at closing. There is also a quieter option worth knowing about: if your goal is a lower payment rather than cash, a mortgage recast may get you there without new debt at all.
Which path wins depends on the size of the need, how long you will carry the balance, and the rate on your current mortgage. That last variable matters more than most people expect.
When does a cash-out refinance beat a HELOC?
A conventional cash-out refinance usually wins when you want a larger lump sum, a fixed payment, or your current mortgage rate sits close to today’s market. The 30-year fixed averaged 6.66 percent for the week ending July 30, 2026, per Freddie Mac’s Primary Mortgage Market Survey, so an owner still paying 7 percent or more may be able to pull equity and improve the first-mortgage rate in a single step. A HELOC tends to win for smaller, staged expenses when your existing rate is far below the market.
Full disclosure: Mortgage Austin does not originate HELOCs. We focus on Conventional, VA, and FHA loans because a narrow product line lets us push files through at competitive rates with fast turn times. That focus means the honest answer is sometimes “keep your 3.25 percent first mortgage and get the HELOC from your bank.” When the numbers point the other way, a conventional cash-out often delivers more money at a predictable cost. You can see where rates stand this week on our Austin mortgage rates page, and our conventional loan overview covers how cash-out qualifying works.
| Factor | HELOC | Conventional cash-out refinance |
|---|---|---|
| Rate type | Usually variable, tied to prime | Fixed for the life of the loan |
| Lien position | Second lien behind your mortgage | Replaces your first mortgage |
| Interest charged on | Only what you draw | The full new loan balance |
| Texas borrowing cap | 80% combined loan-to-value | 80% loan-to-value |
| Monthly payment | Can rise or fall with rates | Same every month |
| Often the better fit | Smaller, staged expenses while keeping a low first-mortgage rate | Larger lump sums, or when your current rate is near today’s market |

Frequently Asked Questions
How much can I borrow with a HELOC in Texas?
Texas caps all debt secured by your primary home at 80 percent of its market value. On a $445,000 home with a $250,000 mortgage balance, that leaves roughly $106,000 of borrowing room across all home equity products. Individual lenders often set lower limits based on credit, income, and the appraisal.
Do Texas HELOCs have a waiting period?
Yes. Texas law requires at least 12 days between your home equity application and the closing. The closing must also take place at the office of a lender, attorney, or title company. Expect a Texas HELOC to take longer to open than lines advertised in other states.
Can I get a HELOC on a rental property in Texas?
The Texas home equity rules discussed here apply to your primary residence, called your homestead. Investment properties fall under different rules, and far fewer lenders offer equity lines on them. Investors more often use a cash-out refinance on the rental, which follows conventional investment-property guidelines instead.
Will opening a HELOC hurt my credit score?
Expect a small, usually temporary dip from the hard inquiry and the new account. The bigger long-term factor is how much of the line you keep drawn, since high utilization can weigh on your score. A HELOC with a modest balance that is paid on time generally has little lasting effect.
Is HELOC interest tax deductible?
Under current IRS rules, interest on home equity borrowing is generally deductible only when the funds are used to buy, build, or substantially improve the home securing the loan, and only if you itemize. Money drawn for other purposes, like paying off credit cards, typically does not qualify. Confirm your situation with a tax professional.
Does Mortgage Austin offer HELOCs?
No. Mortgage Austin originates Conventional, VA, and FHA loans, including conventional cash-out refinances. When a HELOC from a bank or credit union is the better fit for your situation, we will tell you that directly. When a cash-out refinance pencils out better, we can run both sets of numbers so you can compare.
