How Much Can You Borrow on an Investment Property HELOC on a Texas Second Home?

The Quick Read: It depends on how the lender classifies the property, but the Texas 80% homestead cap does not apply to a second home or rental, so the limit comes from the lender’s own program table, which on an investment property across Lendmire’s wholesale network is a 70% combined loan-to-value (CLTV) ceiling and a $500,000 maximum line.

• On an investment property, the 70% CLTV ceiling is open to credit profiles of 700 and up, which is also the minimum.
• On a second home, the ceiling reaches 90% CLTV, but only at a 720-or-better credit profile.
• Second-home and investment lines start at $25,000, and a line above $500,000 is reserved for primary residences.
• The title must be in an individual’s name or a revocable living trust, not an LLC.

Why Texas’s Famous 80% Cap Doesn’t Apply Here

Texas’ equity-lending limits protect a homestead, which is the owner’s primary residence. A second home or rental is a non-homestead property, so those limits do not attach to it.

Texas A&M’s Real Estate Research Center explains that the constitutional section covers cash-out refinances, home equity loans and HELOCs on the home. It also describes the 80% limit on the new loan, added to all other debt secured by the home, as applying to a homestead. The wording is about “your home.” Nothing in it reaches a lake house, a ski condo, or a duplex you rent out.

Here is what changes for a non-homestead Texas property:

• The 80% combined cap does not apply.
• The one-lien-at-a-time rule does not apply.
• The 12-day waiting period and the 12-month seasoning requirement do not apply.

Those rules bind primary residences only. Texas second homes and investment properties are eligible as non-homestead transactions.

Fewer rules does not mean unlimited borrowing. The lender’s table replaces the constitution as the ceiling, and that table can be tighter than the state’s own cap. NerdWallet notes that investment-property lines come with a smaller pool of lenders and less borrowing power than a line on a primary home.

How Is the Maximum Line Calculated?

The maximum line is the property’s value times the lender’s CLTV cap, minus every lien already on the property, then trimmed by the dollar limit and your credit and debt tests. Lenders count the full line as if you had drawn all of it.

The steps run in this order:

1. Establish value. Lines of $500,000 or less ordinarily use an automated valuation rather than a traditional appraisal. A higher CLTV may call for a secondary valuation, and a borrower can request a full appraisal in any case.

2. Apply the CLTV cap for the occupancy type and credit profile.

3. Subtract the first mortgage and any other liens.

4. Check the dollar ceiling. On a second home or rental, the line tops out at $500,000.

5. Run the borrower tests. Debt-to-income (DTI) is capped at 50%. A second home needs at least a 640 credit profile and an investment property at least 700, but a ratio above 45% still requires a credit profile of 680 or more, even for a file that clears those floors. The lender reviews your file on the interest-only payment calculated on the maximum draw.

That last point matters. A larger line can raise the payment used to qualify you, even if you plan to draw only part of it.

Second Home vs. Investment Property: Two Different Rows

The network’s table is tiered by occupancy, and the gap between the two rows is wide.

The 90% figure exists only for a 720-or-better credit profile. Lower scores sit in lower tiers, so a second-home borrower should not assume the top number applies to them. On the investment row, credit above 700 buys eligibility, not leverage, because 720 and 700 reach the same 70% ceiling.

For comparison, Experian reports that investment-property HELOCs are commonly capped near 80% CLTV across the broader market. That is a market-wide figure. On Lendmire’s network the investment-property ceiling is 70% CLTV. If a bank elsewhere advertises more, that is that bank’s table, not this one.

Is Your Property a Second Home or a Rental?

The lender decides, based on how the property is occupied and used. A home you use yourself and never rent is a second home. A property you rent out as a regular source of income is underwritten as an investment property, and the 70% ceiling and 700 credit minimum apply to it.

This is the decision that moves your borrowing power most. Occasional personal use of a rental does not turn it into a second home. The straightforward move is to tell the lender how the property is really used and let the right row apply. Misclassifying it to reach 90% creates a problem on the file, not a solution.

Two Worked Examples (in Percentages)

Both examples are modeled assumptions, not market data.

Example one: a Texas rental. Say the property is a duplex and the first mortgage sits at 45% of its value. At a 70% CLTV ceiling, the full line can add up to 25 more points of value. The borrower needs a 700 or better credit profile and title in their own name. On a higher-value property, the $500,000 line cap would bind before the percentage does.

Example two: a Texas second home. Say the borrower has a 720-plus credit profile and the first mortgage sits at 55% of value. At a 90% CLTV ceiling, the line could add up to 35 points of value, subject to the $500,000 cap and full file review. Drop below 720 and the tier changes, so the headroom shrinks.

The pattern: the same first mortgage leaves very different room depending on occupancy. A rental with a modest first mortgage still has room. A rental carrying a heavy first mortgage may have none at 70%.

Who Can Hold Title, and What Gets Declined

Title must sit with the individual borrower or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind or land trusts cannot hold title. This is the sharpest structural difference from a DSCR loan, which can be written to an entity, subject to lender program eligibility. A rental already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead.

Several property features end the conversation:

• Properties over 10 acres in Texas are not offered.
• A property listed for sale, or listed within the past 60 days, is ineligible in Texas.
• Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agriculturally zoned properties are not offered.
• A borrower can hold up to three lines in the network, and anyone with more than 15 financed properties is not eligible.

Eligible property types include single-family homes, 2-4 units, PUDs, townhomes and condominiums, including non-warrantable condos.

How the Line Is Structured

An investment line is a standalone line, in first or second lien position, with a 5-year interest-only draw followed by a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing. Pricing floats through both the draw and the repayment period and does not convert to a fixed structure.

After closing, the minimum subsequent draw in Texas is $4,000 on the longer-runway program, which is the 5-year-draw, 25-year-repayment structure. The higher-leverage program, which carries the 90% second-home tier, does not state a subsequent-draw minimum. Where the two programs differ, each figure applies only within its own terms.

Practically, the 75% draw requirement means this is not a “borrow only when needed” cushion the way a primary-residence line can feel. Plan for most of the line to be outstanding from day one.

Credit has its own mechanics. Lenders use a single-bureau score keyed to the primary wage earner, and the report can be no more than 90 days old at closing. Investment lines floor at 700, and housing and tradeline history standards vary by program. Bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure-family history on an investment file follows a 7-year seasoning path, with 4 years for a deed-in-lieu, pre-foreclosure or short sale.

When the Texas Property Is Actually Your Homestead

Everything above flips if the property is your primary residence. A Texas homestead caps at 80% combined loan-to-value, carries the 12-day waiting period and the one-lien-at-a-time rule, and requires 12-month seasoning. The network’s higher tiers never apply to a Texas primary.

Using homestead equity to buy or fund a rental is a separate route. The homestead line stays tied to the homestead, and the constitutional protections that govern it are described in Texas A&M’s explainer. You cannot pledge the rental as additional collateral to stretch it. If you own both a homestead and a second home, each property is evaluated under its own rules, and each line counts toward your three-line limit.

Key Terms Defined

CLTV (combined loan-to-value): Your first mortgage plus the full line plus any other liens, divided by the property’s value.

Homestead: The Texas owner’s primary residence, which carries the state’s special equity-lending protections.

Non-homestead property: A second home or rental, which sits outside those constitutional limits.

Draw period: The stretch when you can borrow from the line and pay interest only.

Revocable living trust: A trust you can change or cancel, which may hold title on these lines when the individual borrower is the trustor.

Is a HELOC the Right Tool, or Is DSCR?

A HELOC and a DSCR loan answer different questions. A HELOC keeps your first mortgage in place and qualifies you personally, using credit, income and DTI. A DSCR cash-out refinance replaces the first lien and qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.

The DSCR side works like this. Coverage compares rent to the full monthly obligation, meaning principal, interest, taxes, insurance and any HOA dues. A 1.00 coverage ratio is where select programs start, and stronger ratios open better pricing and leverage. 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. Cash-out on a standard rental generally tops out near 75% LTV, with about six months of seasoning as the common expectation. Credit expectations are around 660 on most programs, with 700 and above unlocking the strongest tiers.

Lendmire brokers DSCR financing across 41 markets, including Washington, D.C., and arranges HELOCs only in its 16 full-service states, which include Texas. For a deeper walkthrough, the complete DSCR loans guide covers qualification.

The flip points are practical. If the rental sits in an LLC, or you need more than a $500,000 line, the HELOC is off the table and DSCR is the realistic path. If your first mortgage carries terms you want to keep, a HELOC preserves them. If your credit sits below 700 and the property is a rental, the HELOC is not available at all.
