Investment Property HELOC Rules on a Texas Homestead

The Quick Read: Texas strictly limits a home equity line secured by your primary home, but it does not limit what you spend the money on. You can fund a rental purchase from a homestead line. You cannot put that line on the rental itself, because Texas home equity loans are not allowed on rental or second-home collateral. A line secured by the rental is a separate product governed by the lender’s own investment-property terms.

• A homestead line combined with every other lien on the home cannot exceed 80% of its value.
• A new homestead line carries a built-in 12-day waiting period and a one-lien-at-a-time limit, and it generally cannot close within a year of an earlier equity loan.
• A line secured by a rental follows the network’s investment terms instead: up to 70% CLTV (combined loan-to-value), a 700 minimum credit score, and a $500,000 maximum line.
• The rental purchase loan is underwritten on its own, and borrowed down payment funds are the lender’s call.
• Not all of your equity is spendable, because the 80% cap leaves a cushion you cannot touch.

Key Terms Defined

Homestead: the home you live in as your primary residence, which Texas protects from most forced sales.

50(a)(6) loan: the label for any Texas home equity loan or HELOC secured by a homestead, named after the part of the state constitution that allows it.

HELOC: a home equity line of credit, a revolving credit line secured by a property, from which you draw as needed.

CLTV: combined loan-to-value, meaning all loans secured by the property added together and divided by its value.

Non-homestead: any property that is not your primary home, such as a rental or a second home.

Vesting: how title to the property is held, whether in your own name, a trust, or an entity.

DSCR: debt service coverage ratio, which compares a rental’s monthly rent to its full monthly payment of principal, interest, taxes, insurance, and any association dues.

Seasoning: a required waiting period between two loan events.

Five Questions, Two Sets of Rules

Most confusion here comes from blending two separate questions. The first is whether you can use equity in your Texas homestead to buy a rental. The second is whether you can put a line on the rental. They run on different rules because the rules follow the collateral, not the purpose.

The first four rows are Texas homestead rules. They attach to the home you live in and nowhere else. The last row comes from the network’s investment-line terms, which are lender rules rather than constitutional ones.

How a Homestead Line Funds a Rental

A homestead line works as a normal source of cash for a rental purchase. Texas’ constitution governs this kind of loan. Texas A&M’s Real Estate Research Center explains that the new principal plus all other debt secured by the home cannot exceed 80% of fair market value, so you keep at least 20% equity. The same source says the loan cannot be secured by any other property and cannot be taken on a rental or second home. The restriction is on the collateral, not on how you use the money.

Here is the sequence a typical file follows.

1. Run the capacity math. Take 80% of the home’s value and subtract every existing lien. Picture a first mortgage equal to 30% of value. That leaves room for a new line of up to 50% of value, before the lender applies its own limits.

2. Check for blockers. An existing home equity loan or HELOC on the same homestead blocks a new line, because only one can sit on the home at a time. A new equity loan also cannot close before the first anniversary of an earlier one, even if the earlier loan was paid off. 7 Tex. Admin. Code §153.14 spells out that one-year rule.

3. Respect the waiting period. The lender must give you a prescribed written notice, and the loan cannot close before the 12th day after that notice. Plan the line well before the rental contract needs cash.

4. Draw in allowed ways. Texas requires a minimum of $4,000 for each later draw. Card and check access to the line is not allowed.

5. Keep a paper trail. The rental lender will want the line’s closing documents, the draw, and a clear path from your account to the title company.

6. Close the rental separately. The purchase loan is its own transaction with its own underwriting.

Texas homestead lines also come with a quiet risk. They are non-recourse in most cases, meaning the lender generally cannot chase your other assets. But your home is still the collateral, so a missed payment can still put your house at risk. If the rental underperforms, you still owe the homestead line payment from your other income.

How the Rental Loan Treats Borrowed Down Payment Money

A rental lender cares about two things: the property and you. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The ratio divides rent by the property’s full payment, which includes principal, interest, taxes, insurance, and any association dues. Your homestead line payment is not part of that ratio. You can read the full mechanics in the complete DSCR loans guide.

That does not make the line payment disappear. Clearing 1.00 on coverage is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation. A fully borrowed down payment puts two loans on one stream of rent, and your own cash flow has to carry the line.

Across a wholesale network, programs differ on borrowed funds. Down payment, closing costs, and reserves are three separate buckets, and a lender may treat each differently. Ask before you draw, not after.

For reference, purchase files in the network usually land at 75% to 80% LTV on a purchase, which means 20% to 25% down. Select high-leverage programs reach 85% LTV with roughly a 700 or better score. Coverage of 1.00 is where many select programs start. A separate select-lender path accepts coverage below 1.00, with leverage and terms adjusted. Every file is reviewed individually, and none of this is a commitment to lend.

What About a Line on the Rental Itself?

A line on the rental sits outside the homestead rules entirely. Texas second homes and investment properties are eligible as non-homestead transactions in this network, so the homestead waiting and seasoning requirements are not part of the picture.

The terms are tighter than many investors expect. In the network, an investment-property line is built like this:

• Leverage: up to 70% CLTV, with no tier above it.
• Credit: a 700 minimum, which is a hard floor with no tier beneath it. A score above 700 buys eligibility but not extra leverage, because the ceiling stays at 70% CLTV.
• Line size: $25,000 to $500,000 maximum.
• Structure: a 5-year interest-only draw followed by a 25-year repayment period. At least 75% of the line is drawn at closing. Pricing floats and never converts to fixed.
• Valuation: because the line caps at $500,000, it ordinarily uses an automated valuation without a traditional appraisal, though a borrower can request one.
• Debt ratio: 50% maximum DTI, meaning your total monthly debts against your income, calculated on the interest-only payment at the maximum draw.
• Properties: single-family, 2-4 units, PUD, townhome, and condominium, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not eligible.

Here is a quick illustration. If your first mortgage on a rental equals 50% of value, a 70% CLTV ceiling leaves room for a line of up to 20% of value, still capped at $500,000. Equity alone does not set the number. The ceiling, the credit tier, and the payment test all do.

The network offers these lines in 16 full-service states, Texas among them. That footprint is narrower than the 41-market DSCR footprint, which covers 40 states plus Washington, D.C. Programs change, so confirm current availability.

Where the General Rule Breaks

The headline rule says a homestead line is fine and a rental can’t carry one under Texas’ equity-loan category. These edge cases bend that picture.

• A prior equity loan or recent cash-out refinance on the homestead. It blocks a new line until it is paid off or replaced, and the one-year clock runs from its closing date. A modification before one year is not barred, and under the state rule the original loan and the modification count as one transaction. Pay-off-and-replace is a different thing.
• Merging a first mortgage and a line. Combining them produces a new equity transaction, so every homestead rule applies again.
• A rental already deeded to an LLC. The network’s investment line requires title in your name or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A property already in an entity needs a vesting change, or a DSCR cash-out refinance instead, subject to program terms.
• A property listed for sale. It is ineligible in Texas if currently listed or listed within the past 60 days.
• Acreage. Texas properties in these programs are limited to 10 acres.
• Portfolio size. A borrower is limited to three lines in total, separate from the size of any single line, and an owner of more than 15 financed properties is not eligible.
• Former residence turned rental. Occupancy decides which rules apply. A home you live in is a homestead. Once it is a true rental, the investment-line terms apply, and the lender decides how to classify it.
• Ineligible property types. Manufactured homes, log homes, and barndominiums fall outside the network’s DSCR programs entirely.

Which Route Fits Your Deal?

There is no single best route. The right one depends on how much equity sits where, what else is on your homestead, and how the rental will be held.

A DSCR cash-out refinance can be the better fit when the rental is in an LLC, when your score is under 700, or when you want rent coverage rather than a revolving line. Standard rental collateral tops out around 75% LTV on a cash-out across most of the network. Short-term rentals tend to run lower, with 70% the cash-out ceiling for that collateral.

The strongest files clear both tests: enough equity and enough rental coverage. A bigger down payment can lift the coverage ratio, but it never erases leverage caps, credit floors, reserve rules, or property eligibility.
