The Quick Read: A HELOC on a Texas homestead works alongside your first mortgage, with both liens counted together against an 80% combined loan-to-value cap, so the line is sized by the equity left after the first mortgage balance. In Texas, “combining” almost never means merging the two loans into one. It means stacking a line behind or beside the first mortgage, or replacing both with one new loan that carries its own rules.
- The combined cap on a Texas primary residence is 80% of the home’s value, counting the first mortgage and the full line.
- Only one equity-type loan can sit on a homestead at a time, so the first mortgage’s origin matters.
- The home you live in is never DSCR collateral. The line sits on the homestead, and the DSCR loan sits on the rental.
- Clearing the DSCR ratio on the rental is a separate test from qualifying for the line on the home.
What Does “Combining” Actually Mean?
Combining means one of three things in practice. You keep the first mortgage and add a line behind it. You take a line in first position and skip the first mortgage entirely. Or you refinance both liens into a single new loan.
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.
Each path gets a different answer on a Texas homestead. Texas treats home equity borrowing as its own legal category, not as an ordinary second mortgage. That is why the generic advice about merging a first mortgage and a HELOC fails here.
The more common move among investors is not a merger at all. It is a line on the home they live in, used for the cash needed on a rental purchase. The homestead stays the homestead, and the rental gets its own loan.
For the conventional version of merging two liens into one, Lendmire’s piece How to Combine a First Mortgage and a HELOC Into One Conventional Loan covers the general mechanics. This article stays on the Texas-specific problems.
Why Is a Texas Homestead Different?
A Texas homestead is protected from forced sale except for a short list of debts, and home equity lending is one of the exceptions. A lien that does not follow the rules can be invalid. That is the whole reason the process looks different from other states.
Texas A&M’s Real Estate Research Center lists the practical effects. A lender must give a separate written notice before closing, and timing varies by file and lender. Only one such loan can be made in a 12-month period, even if the earlier loan was repaid. No prepayment penalty is allowed. These loans cannot be taken on a secondary residence or a rental.
Those last two facts matter for investors. The homestead rules bind only the homestead. A line on a rental property is a different transaction with different guidelines.
A line on the homestead also needs Texas-specific closing steps. The closing documents must be prepared or reviewed by a Texas-licensed attorney, per the same Texas A&M article. That is a plan-ahead item, not a last-minute one.
Key Terms Defined
HELOC: A revolving line of credit secured by a property, with a draw period where you borrow and a repayment period where the balance is paid down.
Combined loan-to-value (CLTV): All liens on the property added together and divided by its value. On a Texas homestead, the cap is 80%.
Homestead: The home you occupy as your primary residence, which receives special protection under Texas law.
Equity-loan category: The Texas legal bucket that covers cash-out refinances, home equity loans, and lines on a homestead. Only one can be in place at a time.
Lien position: Whether the line sits first or second behind a mortgage. The network’s lines can sit in either position.
DSCR: The ratio of a rental’s income to its full monthly obligation (principal, interest, taxes, insurance, and HOA dues where they apply).
How Do You Size the Line? The Ceiling Math
Take the home’s value at 80%, subtract what the first mortgage balance represents, and what remains is the room for a line. The test also counts the full credit limit, not just the amount you draw on day one. A line you plan to draw lightly still uses its entire limit against the cap.
Expressed as percentages of the home’s value, the picture looks like this.
| First mortgage balance | Room under the 80% cap | Result |
|---|---|---|
| About 55% of value | About 25% of value | Room for a meaningful line |
| About 70% of value | About 10% of value | A small line fits |
| About 80% of value | None | No line fits |
The network’s own tiers sit under that state cap. On a Texas primary residence, a 640 or better credit profile can reach the 80% combined ceiling, with lines up to $500,000. A 620-plus profile reaches 70% combined on lines up to $400,000, and a 600-plus profile reaches 60% on lines up to $400,000. The 90% and 85% tiers that appear in the program matrix never apply to a Texas primary residence. Every figure here is subject to lender guidelines and a full file review.
Two more guardrails apply on the lender side. Debt-to-income is capped at 50% maximum, with 45% for credit profiles from 600 to 679. And lines at or below $500,000 ordinarily run an automated valuation, while anything above that needs a full appraisal. A borrower can always ask for a full appraisal.
What Does the One-Lien Rule Do to Your Options?
It decides whether a HELOC can be added at all. The first thing a title company checks is how your current first mortgage was classified.
A purchase-money first mortgage, or a refinance that only replaced it, leaves the equity slot open. A first mortgage that was itself a cash-out refinance already used the slot, so a line cannot be stacked behind it. The title commitment is the arbiter here, not your memory of the closing.
The same logic means a homeowner who already has an equity loan or line on the home cannot add a second one. There is also the 12-month limit noted above. Repaying a loan does not reset that clock, per the Texas A&M article. For that reason, the first mortgage type you choose when you buy a home affects your options years later.
The network applies this to primary residences only. The 12-day waiting period, the one-lien-at-a-time rule, and the 12-month seasoning all bind a Texas primary residence. Second homes and investment properties in Texas are eligible as non-homestead transactions.
Your Three Paths on a Homestead
Which path fits depends on whether the first mortgage is worth keeping and whether the slot is open.
| Path | First mortgage | The line | Best when |
|---|---|---|---|
| Keep both | Stays in place | Added behind it | The first mortgage is worth keeping and the slot is open |
| Line only | None, or paid off separately | Sits in first position | There is little or no first mortgage |
| Replace both | Paid off by a new loan | Paid off by the same loan | Combined balances fit under the cap and a single payment makes sense |
The third path carries the most legal weight. A new loan that pays off both liens has to follow the Texas equity-loan rules, and the details of classification belong to a Texas title attorney. This article stops at saying that special refinance rules exist for refinancing an equity loan. The right move is to get that structure confirmed by counsel before applying.
What Is the Step-by-Step Sequence?
The sequence is the same in most Texas files. Skipping a step causes the delays, not the market.
1. Confirm the homestead and the slot. Pull the title commitment and check how the existing first mortgage was classified.
2. Run the ceiling. Check the first mortgage balance and the full proposed credit limit against the 80% combined cap.
3. Choose the structure. The network offers a 3-year interest-only draw with a 17-year repayment period, and a 5-year interest-only draw with a 25-year repayment period. On a primary residence, either one can apply. Pricing floats during both periods and never converts to a fixed structure. At least 75% of the line is drawn at closing.
4. Apply and receive the notice. Under the constitutional text mirrored by FindLaw, the earliest closing date is the 12th day after the later of two events: the application or delivery of the notice. Closing happens at a lender’s office, an attorney’s office, or a title company.
5. Close, then wait out the cancel period. The State Bar of Texas explains that the owner or spouse can cancel without penalty during a rescission period after closing, and both spouses must sign. The length of that window and the timing of when funds become available vary by file and lender.
6. Draw as needed. After closing, each Texas advance must be at least $4,000. No credit card, debit card, or unsolicited pre-printed checks can be used to draw. A named borrower may request an advance, and 7 TAC §153.82 notes that a HELOC agreement can require all borrowers to consent.
Plan the full sequence before you go under contract on a rental. A line that is not in place when the contract needs cash is a line that does not help you.
What Does the Lender Look At Besides the Cap?
The constitution controls the collateral, and the lender controls the borrower. A file can pass one test and fail the other.
On the lender side, the credit floor for the network’s lines is 600, and the score model is a single-bureau score keyed to the primary wage earner. A report cannot be more than 90 days old at closing, and there are no rescores. Tradeline and housing-history standards vary by program. Bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure-family history is treated differently across the network. Some lenders season a foreclosure at 7 years and a deed-in-lieu or short sale at 4 years, and others decline the history regardless of its age.
On the property side, single-family, 2-4 unit, PUD, townhome, and condominium properties are eligible, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered. Texas properties are limited to 10 acres. A property listed for sale, or listed within the past 60 days, is ineligible in Texas.
Title has to be held by the individual borrower or a revocable living trust. An LLC cannot hold title on these lines. A Texas attorney’s analysis adds that deeding a homestead to an LLC with a condition such as a repurchase option or a lease may be declared void, which leaves the property as the borrower’s homestead. For a homestead, the LLC is the wrong vehicle.
Network availability applies only to Lendmire’s 16 full-service states, Texas among them, which is narrower than its DSCR footprint. Lendmire brokers these lines through select wholesale partners and is never the lender.
Where Does the DSCR Loan Come In?
The DSCR loan goes on the rental, not the home. A homestead is owner-occupied, so it never becomes DSCR collateral. A DSCR loan is built for non-owner-occupied investment property, and it is reviewed differently from a standard owner-occupied mortgage.
The pairing works like this. The investor draws on the homestead line and puts the funds toward the rental’s down payment or closing costs. The DSCR loan then qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
On most files in the network, a purchase lands at 75% to 80% LTV, which means 20% to 25% down. Select high-leverage programs reach 85% LTV with a score around 700 or higher. A DSCR of 1.00 is where select programs start, not a universal standard, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Reserves vary by lender, leverage, and loan size, commonly around 6 months of PITIA.
Consider an investor buying a rental at 75% LTV with rent covering the full obligation at roughly 1.2x. That investor needs 25% of the price in cash, and the homestead line is one way to source part of it. Whether a given DSCR program accepts borrowed down-payment funds, and how it treats the line’s payment, depends on the lender and the file. Draw early enough that the funds season in your statements, and expect the line’s payment to show up in any debt-to-income review.
Keep one distinction clear. The line is extra debt on the home you live in, with variable-rate exposure after the interest-only draw period. Texas requires substantially equal payments in the repayment period. And clearing 1.00 on a rental is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capex sit outside the calculation. Lendmire’s complete DSCR loans guide covers how the ratio is built.
A practitioner note from across the network: files that stack a homestead line and a DSCR purchase most often run into sequencing, not qualification. The line closes later than the contract needs it, or the draw lands in the bank a few days before the lender reviews statements. Treat the line as a first step, not a final one.
What About a HELOC on the Rental Itself?
A line on a rental is a different transaction. The homestead rules do not apply to it, since Texas A&M notes the homestead equity-loan category does not reach rentals or second homes.
The network’s investment-property lines cap at 70% combined loan-to-value, require a 700 minimum credit profile, and top out at $500,000 total. Investment lines run only the 5-year interest-only draw with a 25-year repayment structure. There is no tier above $500,000 on an investment property. Lines above $500,000 are available only on a primary residence.
The vesting rule applies here too. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out instead, subject to program terms. For a related option, see Lendmire’s piece Can You Keep Your First Mortgage and Open a Bank Statement HELOC in Texas?.
Where Does the General Rule Break?
A few edge cases change the answer.
An existing line. A homeowner with an existing HELOC may be able to take further advances up to the original maximum and terms. The $4,000 minimum draw still applies. That is older regulator guidance, so confirm it for your specific line.
Refinancing an equity loan. Special rules cover this, and they are a counsel question. No plain-language shortcut exists.
Bank-held lines. Some lenders do not offer Texas lines, or offer them only in modified form, because of the draw rules. Card-linked lines and non-use fees are the usual casualties.
Exposure limits. A borrower is limited to three lines in the network. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the program with the longer interest-only runway. A borrower owning more than 15 financed properties is not eligible.
Common Misreadings
“The waiting period runs after closing.” It runs before it. Closing cannot occur until the required waiting period has passed after the later of application or notice, and the actual timing varies by file and lender.
“A Texas line is looser than a cash-out refinance.” It is not. Texas treats both in the same legal category, with the same penalties for violations.
“The 80% cap applies only to the new line.” It counts every lien, including the first mortgage.
“Repaying the loan resets the one-year clock.” It does not.
“The rules apply to my rentals too.” They apply only to the homestead.
Frequently Asked Questions
Can I merge my first mortgage and a HELOC into one loan on a Texas homestead?
Only by replacing both with a new loan that follows the Texas equity-loan rules. The combined balances and the new line must fit under the 80% combined cap. Because the classification of that new loan has legal consequences, confirm the structure with a Texas title attorney first.
How much can I borrow against my homestead?
The maximum is set by the 80% combined cap, minus the first mortgage balance, and the full credit limit counts. The network’s own tiers add credit and line-size limits under that state cap. A 640-plus profile can reach 80% combined on lines up to $500,000, subject to lender guidelines.
Can a Texas HELOC fund the down payment on a rental?
The funds can be used that way, but each DSCR program decides whether borrowed down-payment funds are acceptable. Draw early so the funds season, and expect the line’s payment to count in any debt-to-income test. A DSCR loan on the rental qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
Does a Texas HELOC work on a rental or second home?
The homestead rules do not reach them, but different guidelines apply. On the network, second homes and investment properties in Texas are eligible as non-homestead transactions. Investment lines cap at 70% combined loan-to-value, require a 700 credit profile, and top out at $500,000.
Can I put my homestead in an LLC before borrowing against it?
No. These lines require title held by an individual or a revocable living trust. A homestead deeded to an LLC with conditions may also be declared void, which leaves it the borrower’s homestead.
Next Steps
If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals. 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. Programs change, and every file is reviewed individually, so none of this is a commitment to lend.
