Can You Put a HELOC Behind an FHA Loan on a Texas Homestead?

The Quick Read: Sometimes, but only when the FHA first lien is a purchase-money or ordinary rate-and-term loan rather than a Texas cash-out loan, and the combined debt stays at or below 80% of the home’s value. Texas law and FHA’s own rules both have to be satisfied, and a title review decides which side of the line the file lands on.

• A Texas homestead HELOC is a home equity loan under Section 50(a)(6) of the state constitution, and only one such lien can sit on the home at a time.
• An FHA purchase-money first lien is not a Section 50(a)(6) lien, so a HELOC behind it is legally possible.
• An FHA first lien that came from a Texas cash-out refinance usually blocks a HELOC behind it.
• Combined debt on a Texas primary residence caps at 80% of value on this network.
• A HELOC on a homestead is consumer equity. It is not a DSCR loan, and DSCR only enters the picture if the home becomes a rental.

Most Texas homeowners with an FHA loan ask this question for one reason: they want cash from equity without refinancing out of a first mortgage they like. The answer lives in two places. One is the Texas Constitution. The other is FHA’s own handbook. This article walks through both, shows where files break, and covers what changes if the home turns into a rental.

Why Texas Homestead Rules Change the Answer

Texas treats the homestead differently from almost every other state. The Texas Constitution, Article XVI, Section 50 shields the homestead from forced sale except for a short list of debts. A home equity loan is one of those listed debts, but only if it meets strict conditions.

The main conditions: the lien must be voluntary, and the new principal plus all other debt secured by the home cannot exceed 80% of fair market value on the day credit is extended. Texas also requires a written notice before closing and a closing at the office of the lender, an attorney, or a title company. The constitution’s HELOC notice language repeats the 80% limit.

A HELOC is not exempt from any of this. In Texas, a home equity line and a closed-end home equity loan are both Section 50(a)(6) loans. They share the same 80% cap and the same notice rules.

On the lending side, the network applies the same 80% combined cap to a Texas primary residence. Higher tiers on a standard equity-line matrix never apply to a Texas homestead. That is a program limit sitting on top of the constitutional one.

The One-Lien Rule and Why the First Mortgage Matters

Only one Section 50(a)(6) lien can sit on a homestead at a time. That means a closed-end equity loan and a HELOC cannot coexist. It also means the type of first mortgage matters more than most borrowers expect.

Here is the check that decides most of these files: is the existing first lien itself a Section 50(a)(6) loan?

• A purchase-money loan is a separate permitted category in the constitution. An FHA loan used to buy the home is in this group. It does not use up the one equity-loan slot.
• A cash-out refinance on a Texas homestead is generally a Section 50(a)(6) loan. If an FHA refinance paid out cash, the first lien may already hold the slot.
• A rate-and-term refinance with no cash out can stay outside Section 50(a)(6), but only if it did not refinance an earlier equity loan. Texas practitioners describe that as once an equity loan, always an equity loan: refinancing an equity lien into a new first lien does not always wash the label off.

The same logic shows up in agency material. The Fannie Mae Selling Guide section on Texas 50(a)(6) loans states that HELOC subordinate financing is not permitted behind a Texas 50(a)(6) first lien. That is conventional-agency material and not an FHA or DSCR rule. It shows how the industry treats the stacking problem.

Getting this wrong is costly. A HELOC placed behind a first lien that is already a 50(a)(6) loan is a defect that is hard to cure. Texas courts have treated liens that secure noncompliant home equity loans as invalid until the defect is fixed. A misclassified first lien can undo the whole structure.

Where Your FHA Loan Sits

The table below sorts the common FHA scenarios by how they interact with a later HELOC. It reflects the constitutional structure and general practice. A title review and Texas counsel have the final say on any file.

A freshly purchased FHA home usually has little room to work with. FHA purchase loans start at high leverage, so the combined-debt test often fails until the balance drops or the value rises. The legal path can be open while the math is still closed.

FHA’s Own Side of the Test

Texas law is the first gate. FHA is the second. FHA’s governing rulebook is HUD Handbook 4000.1. Subordinate financing behind an FHA loan has to be disclosed, and the borrower has to show they can afford the total payments. FHA also limits combined leverage of the first and any subordinate liens.

The details change over time, and current handbook sections should be read directly before relying on any one number. The practical takeaway is that a HELOC behind an FHA loan has to satisfy both sets of rules. A line that passes the Texas 80% test can still fail on FHA’s affordability or combined-leverage review.

FHA is also an owner-occupant program. If the plan is to rent the home out, that occupancy question comes up before the HELOC question does.

How to Check Your First Lien Before You Apply

Run this sequence before any application goes in:

1. Pull the title commitment and the recorded deed of trust. Look at whether the FHA lien is purchase-money, rate-and-term, or cash-out.

2. Check for prior equity liens. A past equity loan that was refinanced into the FHA loan can carry the label forward.

3. Run the 80% test. Add the FHA balance, every other lien of record, and the full HELOC limit. The total must stay at or below 80% of fair market value, which the appraisal or valuation supports.

4. Plan for the notice period. Texas requires the equity-loan notice well before closing, and the loan cannot close until the waiting period has run.

5. Gather the Texas documents. Expect the title commitment, the FHA deed of trust, the HELOC security instrument with the Section 50(a)(6) disclosure, the notice, and the Texas home equity affidavit and agreement. The Texas Bankers Association confirms the security instrument has to carry that disclosure.

6. Ask for attorney review. Lenders often skip a separate title policy on a HELOC, so counsel may be the only check on the lien’s validity.

Draw rules matter too. Texas has its own framework for how a line can be drawn after closing, and the network sets a $4,000 minimum subsequent draw in Texas. Program terms change, so confirm them at the time of the request.

Three Scenarios

These are modeled borrowers, not real files, and the leverage figures are illustrative.

Scenario one: the clean purchase-money file. A buyer used an FHA loan to buy a primary residence a few years ago. The title shows no prior equity lien. Appreciation and paydown have pushed combined leverage, including a proposed line, to a level that sits within the primary-residence tier for a credit profile in the 700 range, and Texas caps the combination at 80% of value. This file can work, subject to lender guidelines and a full review.

Scenario two: the FHA cash-out file. A homeowner refinanced into an FHA loan and took cash out. Texas treats that loan as a Section 50(a)(6) loan, so the one equity slot is already used. A HELOC behind it is generally blocked. The options are to wait, to refinance the first lien into a structure that clears the slot, or to take equity another way. Counsel confirms which path applies.

Scenario three: the recent buyer. An FHA purchase closed recently with minimal equity. The legal path is open, but combined leverage is already near the FHA starting point. The HELOC math fails the 80% test, so the practical answer is to wait for paydown or appreciation.

If the Answer Is No

A no on the HELOC does not end the equity conversation. The usual alternatives:

• Wait. Paydown and appreciation improve the 80% test. Seasoning can also matter, since Texas spaces out 50(a)(6) loans and the network applies a 12-month seasoning rule on primary residences.
• Restructure the first lien. A refinance that clears the equity label is a different transaction with its own review.
• Use equity from a non-homestead property. Rentals and second homes sit outside the homestead rules. Texas A&M’s Real Estate Research Center explains that Texas home equity loans are secured by the homestead only and cannot be made on a rental or investment property. A line on a Texas investment property is a non-homestead transaction, with its own network terms: a 700 minimum credit profile, a 70% combined ceiling, and a $500,000 maximum line.

When the Home Becomes a Rental

This is where the investor decision starts. Moving out and renting the home does not end homestead status on its own. Homestead is lost through abandonment, alienation, or death, and a lease by itself does not end it. Texas homestead protection also runs to individuals, not to LLCs. A homeowner who stacks a HELOC on a homestead and later converts the property is carrying a Section 50(a)(6) lien into the rental phase.

Plan the exit before borrowing. A prior equity lien can follow the title, and it may need to be cured or addressed before an investor-terms refinance. Once the property is truly a non-owner-occupied rental, DSCR is the relevant lens. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.

On most DSCR files the property qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Cash-out refinance tops out around 75% LTV across most of the network, with about 6 months of seasoning as the common expectation. Coverage of 1.00 is where select programs start, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Credit of 660 is typical, and 700 or better opens the strongest leverage tiers. Reserves vary by lender, leverage, and loan size, commonly around 6 months of PITIA.

Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, and capex sit outside the calculation. For the full program picture, see the complete DSCR loans guide.

Where These Files Break

The failure points are predictable:

• Misread first lien. The most common and hardest-to-cure error is placing a HELOC behind a first lien that is already a 50(a)(6) loan.
• Stale value. The 80% test runs on value on the date credit is extended. A value that was fine at application can drift.
• Missing Texas documents. The notice, the affidavit, and the disclosure language all have to be in the file.
• Title held in the wrong name. The network requires title held by the individual borrower or a revocable living trust. A property deeded to an LLC cannot take the line and needs a vesting change or a DSCR cash-out instead.
• Ineligible property. Manufactured homes, log homes, and co-ops are not eligible, and Texas properties are limited to 10 acres.
• Listed property. A property listed for sale, or listed within the past 60 days, is ineligible in Texas.

Key Terms Defined

Homestead: the home a Texas owner lives in as a primary residence, which state law shields from forced sale except for listed debts.

Section 50(a)(6) loan: a Texas home equity loan or HELOC that must meet the constitution’s conditions, including the 80% combined cap.

Combined loan-to-value (CLTV): all loans secured by the home added together and divided by its value.

Purchase-money lien: a loan used to buy the home, which Texas treats as a separate permitted category.

Subordinate financing: a second lien that sits behind the first mortgage.
