The Quick Read: A Texas homestead can carry a HELOC behind a first mortgage, but only when the first lien is not itself a home equity or cash-out loan, and only while total debt stays at or below 80% of the home’s value. The state constitution sets that ceiling, not the lender. A prior cash-out refinance can block the line entirely.
- The combined cap on a Texas primary residence is 80% of fair market value, first mortgage included.
- A purchase-money first mortgage or a rate-and-term refinance generally leaves room for a line. A prior cash-out or equity loan generally does not.
- Texas allows one home equity lien on a homestead at a time, so a HELOC and a closed-end equity loan cannot coexist.
- These rules attach to the homestead only. Rental properties sit outside them.
- Lendmire arranges these lines through select wholesale lenders in its 16 full-service states, Texas included, subject to lender guidelines.
An investor who lives in a Texas home often asks a practical question. Can the equity in that house fund the down payment on the next rental? Sometimes. This piece walks through how the state rules treat the first mortgage, how the lender then layers its own limits on top, where the rules break, and what the decision looks like when the real goal is buying rentals. For the broader picture of investor financing, the complete DSCR loans guide covers the rental side.
How large a line the equity supports in Texas.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 80% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
Key Terms Defined
Homestead: The home a Texas borrower lives in as a primary residence, which gets special constitutional protection and special lending rules.
Combined loan-to-value (CLTV): The first mortgage balance plus the full HELOC limit, divided by the home’s value.
50(a)(6) loan: A home equity loan under Article XVI, Section 50 of the Texas Constitution. Cash-out refinances, closed-end equity loans, and HELOCs all fall in this category.
Purchase-money loan: The loan used to buy the home. It is not a 50(a)(6) loan.
Rate-and-term refinance: A refinance that replaces the old loan without taking cash out.
Cash-out refinance: A refinance that pays the borrower cash from equity. In Texas it is a 50(a)(6) loan.
Why Does Texas Treat Homestead Equity Differently?
Texas treats homestead equity differently because the constitution writes the lending rules directly into its text. Texas Real Estate Research Center at Texas A&M notes that many of the home equity rules sit in the constitution itself, with Section 50(a)(6) setting out the requirements and covering cash-out refinances, home equity loans, and HELOCs.
That has a consequence most borrowers miss. A HELOC is not a separate legal regime. It is a 50(a)(6) loan with extra rules attached. Whatever limits apply to a cash-out refinance on the homestead also shape the line. A lender cannot waive them, and a borrower cannot negotiate around them.
Texas also barred home equity lending for most of its history. A 1997 amendment opened the door, and a later change specifically authorized lines of credit. That history is why the rules read as conservative. They were written to protect the homestead from being stripped by a bad loan.
How Does the First Mortgage Count Toward the 80% Cap?
The first mortgage counts dollar for dollar. Texas measures the new principal plus every other debt secured by the home against 80% of fair market value on the date credit is extended, which leaves the owner with at least 20% equity, per Texas A&M’s Real Estate Research Center.
Here is the formula, step by step.
1. Take the home’s value and multiply by 80%. That is the ceiling.
2. Add the first mortgage balance to the full HELOC limit, not just the drawn amount.
3. If the total is at or under the ceiling, the line fits. If not, the limit shrinks until it does.
The word “full” matters. The test runs against the amount the lender can extend, not against what the borrower draws on day one. A borrower who opens a large line and draws little still uses the room.
Consider a homeowner whose first mortgage is a modest share of the value, say 40%. The state cap leaves room for a line that takes combined leverage up to 80%. A homeowner at 70% already has little room. A homeowner at 80% or above has none. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
The lender’s credit tiers sit underneath the state cap. A Texas primary residence caps at 80% combined, and no higher primary-residence tier applies to a homestead here. For example, a 640-or-better profile can reach 80% CLTV on lines up to $500,000, while a 620-or-better profile reaches 70% up to $400,000. These are typical ranges from select wholesale lenders, subject to lender guidelines and full file review.
Value is also fixed at closing. A home that appreciates later does not enlarge an existing line.
What Kind of First Mortgage Do You Have?
The type of first mortgage decides whether a HELOC can sit behind it at all. A purchase-money first or a rate-and-term refinance does not block a line. A prior cash-out or home equity loan does, because Texas allows only one 50(a)(6) lien at a time.
| First lien type | Can a HELOC go behind it? | What decides it |
|---|---|---|
| Purchase-money mortgage | Generally yes | Combined leverage within 80% |
| Rate-and-term refinance | Generally yes | Combined leverage within 80% |
| Prior cash-out refinance | Generally no | It already holds the 50(a)(6) slot |
| Closed-end home equity loan | No | One 50(a)(6) lien at a time |
| Existing HELOC | No second 50(a)(6) lien | One line at a time |
The one-lien rule comes from Section 50(a)(6)(K), which Texas law firm Polunsky Beitel Green discusses in its MortgageLaw Minute. The firm explains that a HELOC and a closed-end equity loan cannot encumber a homestead at the same time.
The firm also calls the most common and hardest-to-cure error a second-lien HELOC placed on a property whose first lien turns out to be a 50(a)(6) loan. This is the trap. The new line looks like an ordinary second lien. The paperwork reveals that the first mortgage already used the slot.
Violations are costly. An uncured violation can carry penalties that include forfeiture of principal and interest, the same exposure as a closed-end equity loan. That is why lenders check the first lien’s history carefully, and why a file with an unclear first-lien history stalls.
How Do You Find Out Which Kind of First Mortgage You Have?
Look at the closing documents from the loan that is now on the property. The settlement statement and the loan documents show whether the loan was a purchase, a rate-and-term refinance, or a cash-out. If the home has been refinanced more than once, trace each step.
Three places answer the question.
- Closing documents: The loan type is stated, and a Texas cash-out carries 50(a)(6) disclosures and notices.
- Title history: The title commitment lists recorded liens in order. Lenders classify the first lien from it.
- Servicer records: The current servicer can confirm how the loan originated.
Prior equity debt leaves a lasting mark. The refinance provision in Section 50, reproduced by FindLaw, says a refinance of an equity-loan debt is valid only if it is itself an equity loan or meets listed conditions, including an 80% test on the refinance date. In practice a prior HELOC or equity loan can taint later refinances of that same homestead. The shorthand is once an equity loan, always an equity loan.
What Rules Does the State Set, and What Does the Lender Add?
The state sets the cap, the advance rules, and the one-lien limit. Lenders add credit, valuation, and draw terms. Keeping the two apart prevents confusion, because lender numbers vary from the constitutional floor.
State rules (constitutional):
- The 80% combined cap.
- A HELOC is an open-end account where the owner requests advances, repays and reborrows, and cannot use a credit card, debit card, or preprinted check to take advances. Each advance must be at least $4,000, per the Texas Constitution, Article XVI, Section 50, as reproduced by Justia.
- One 50(a)(6) lien at a time.
- Required disclosures and closing-location rules.
- Texas properties are limited to 10 acres under the network’s guidelines.
One caution on that reproduction. The Justia copy appears to include older language, including a clause that halts advances when the balance passes 50% of value. That restriction has been described as no longer applying to newer lines. Check current text with a Texas attorney rather than relying on a reproduction.
Network rules (lender policy, typical):
- Minimum credit of 600, with tradeline and housing-history standards that vary by program. Sub-640 profiles are limited to single-family residences with a clean 12-month housing history.
- Line size from $25,000 to $750,000. A line above $500,000 requires a full appraisal and a credit profile of 700 or better (720 on the longer-runway structure), and caps at 75% CLTV.
- Debt-to-income at 50% maximum, 45% for credit profiles from 600 to 679, and qualified on the interest-only payment at the maximum draw.
- After closing, the minimum subsequent draw in Texas is $4,000, matching the state floor.
- At least 75% of the line is drawn at closing.
- Lines at or below $500,000 ordinarily run an automated valuation, though a higher CLTV may require a second valuation and a borrower can request a full appraisal.
A Texas homestead also carries a 12-day waiting period, 12-month seasoning, and the one-lien-at-a-time rule. These bind primary residences only. A second home or an investment property in Texas is eligible as a non-homestead transaction.
Two draw structures exist on primary residences. One runs a 3-year interest-only draw with a 17-year amortizing repayment. The longer-runway structure runs a 5-year draw with a 25-year repayment. Pricing floats and does not convert to fixed on either. Every figure here is a typical guideline from select wholesale lenders, subject to full file review and not a commitment to lend.
HELOC vs. Home Equity Loan vs. Cash-Out Refinance
All three are 50(a)(6) loans on a Texas homestead. They differ in what happens to the first mortgage and how the money comes out.
| Factor | HELOC | Home equity loan | Cash-out refinance |
|---|---|---|---|
| First mortgage | Stays in place | Stays in place | Replaced |
| Liens after closing | First plus line | First plus loan | One new lien |
| Access to funds | Draw and repay | One lump sum | One lump sum |
| 50(a)(6) slot | Used | Used | Used |
The choice often turns on the first mortgage. A borrower with a low-cost first mortgage may prefer to keep it and add a line behind it. A borrower whose first mortgage is already a cash-out has no slot left for a second 50(a)(6) lien.
Sequencing: Four Cases
Order matters because each 50(a)(6) transaction uses the single slot.
Case one: purchase-money first, no other debt. The slot is open. A line behind the first mortgage works if combined leverage stays within 80% and the borrower meets credit and DTI limits.
Case two: rate-and-term refinance, no cash taken. Same result. The refinance did not use the slot.
Case three: prior cash-out refinance. The slot is taken. A new HELOC generally cannot go behind that first lien. Options narrow to refinancing the first mortgage as an equity loan or waiting out the issue with counsel.
Case four: existing HELOC, borrower wants to refinance the first mortgage. The line holds the slot. A refinance of the first must be reviewed against the equity-debt rules, which can treat the transaction as an equity loan. Plan the order with a Texas attorney before moving.
Where the Rule Breaks: Edge Cases
Stale rules still repeated online. Some pages still repeat an older draw-stop at 50% of value. Treat that with caution and confirm current text.
Lender minimums versus the statute. The constitution sets a $4,000 minimum advance. Some banks set higher draw minimums in their own products. Those are lender choices, not state law. The network’s Texas subsequent-draw minimum matches the state figure.
LLC-held property. A home equity line requires title held by the individual borrower or a revocable living trust. LLCs, corporations, partnerships, and irrevocable or land trusts cannot hold title. That is the sharpest structural difference from a DSCR loan. A property already deeded to an LLC needs a vesting change or a DSCR cash-out instead, depending on program terms.
Property type. Single-family, 2-4 unit, PUD, townhome, and condominium (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not offered.
Listed for sale. A Texas property listed for sale, or listed within the past 60 days, is ineligible.
Foreclosure history. Bankruptcy needs 4 years from discharge or dismissal. Foreclosure history is seasoned at 7 years, and a deed-in-lieu or short sale at 4.
Exposure. A borrower is limited to three lines, and one owning more than 15 financed properties is not eligible.
What the Investor Decision Looks Like
Texas homestead rules apply to the home the borrower lives in. They do not govern the rental. That separation drives the whole investor strategy.
A borrower who lives in a Texas home with a purchase-money first can draw on a line to fund a down payment or reserves on a rental. The line adds a lien and a balance to personal debts. The lender counts the interest-only payment on the maximum draw in DTI, so a large line can crowd out the next purchase if the personal ratios are tight.
Using the money for an investment does not change the collateral’s status. The home stays a homestead and the 50(a)(6) rules keep applying to it.
On the rental side, a DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Most files land at 75%-80% LTV on a purchase. Select high-leverage programs reach 85% at roughly a 700+ score. Coverage of 1.00 is where select programs start, not a universal rule, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Clearing 1.00 is not the same as positive cash flow, since repairs, vacancy, and management sit outside the calculation. Reserves vary by lender, leverage, and loan size, commonly around 6 months of PITIA.
The strongest files clear two tests: enough equity in the homestead to open the line, and enough rental coverage on the investment property. See Lendmire’s piece Texas Rental HELOC vs Homestead Equity Rules That Apply for how the two collateral types differ.
Investment-property lines, for comparison, are a different product. They cap at 70% CLTV, require a 700 credit profile, and top out at $500,000.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Pre-Application Checklist
- Closing documents showing how each current lien originated.
- A title commitment listing recorded liens in order.
- Current first-mortgage balance and servicer contact.
- Evidence the property is the primary residence and under 10 acres.
- Credit report no more than 90 days old at closing, with tradelines and housing history in order.
- Confirmation that title is held by the individual or a revocable living trust.
- Confirmation the home is not listed for sale.
Common Mistakes
- Assuming the 80% cap is new borrowing room rather than total debt.
- Treating any first mortgage as acceptable without checking whether it was a cash-out.
- Opening a line when the first lien already holds the 50(a)(6) slot.
- Quoting an old 50% draw-stop as current law.
- Confusing a lender’s higher draw minimum with the state floor.
- Expecting appreciation to enlarge an existing line.
- Holding the home in an LLC and expecting a line to follow.
Several figures often cited online, including the 12-day waiting period, the 3-day rescission right, and a 2% fee cap, should be confirmed against the primary Texas text before anyone relies on them. A Texas attorney can verify the current requirements for a specific loan.
Frequently Asked Questions
Can I get a HELOC on a Texas homestead if I already have a first mortgage?
Usually, if that first mortgage is a purchase-money loan or a rate-and-term refinance and combined debt stays within 80% of value. A prior cash-out or equity loan generally blocks the line because only one 50(a)(6) lien can sit on the homestead.
Does my first mortgage count against the 80% limit?
Yes. The first mortgage balance plus the full HELOC limit must total no more than 80% of the home’s fair market value on the date credit is extended, per Texas A&M’s research center. Appreciation after closing does not expand the line.
Can I have a HELOC and a home equity loan at the same time?
No. Section 50(a)(6)(K) allows only one 50(a)(6) lien at a time, so a property cannot secure both. A cash-out refinance counts toward the same limit.
Do these rules apply to my rental properties?
No. The 50(a)(6) framework applies to the homestead. A DSCR loan on a rental is a business-purpose loan reviewed on the property’s rental income, subject to lender guidelines. Texas second homes and investment properties are eligible as non-homestead transactions.
What is the minimum I can draw on a Texas line?
The constitution sets $4,000 as the minimum single advance, and the network’s Texas subsequent-draw minimum matches it. Some banks set higher minimums in their own products, which is lender policy and not state law.
