How Much Can You Borrow on an Investment Property HELOC on Texas Acreage?

The Quick Read: It depends on the property’s value and your existing liens, but on Lendmire’s wholesale network an investment-property line tops out at 70% combined loan-to-value (CLTV), up to a $500,000 maximum, and extra acreage does not raise that ceiling.

• Formula: value × 70% CLTV, minus every lien already on the property. The result is capped at $500,000 and must clear the $25,000 minimum line.
• Texas’s 80% cap is a homestead rule. It does not govern a rental or non-homestead tract. A Texas primary residence on this network also stops at 80% combined.
• Credit floor is 700. A 720 score reaches the same 70% ceiling on an investment line, so a higher score buys eligibility, not leverage.
• Title matters. The line goes to an individual or a revocable living trust. An LLC cannot hold title.
• Acreage does not raise the ceiling. Texas properties are limited to 10 acres, and agricultural zoning is not eligible.

What Do These Terms Mean?

Equity lines have their own vocabulary. These are the terms the rest of this article uses.

Key Terms Defined

• HELOC: a revolving line of credit secured by a property you own, with a draw period followed by repayment.
• CLTV (combined loan-to-value): all liens on the property, drawn or not, divided by the property’s value.
• Homestead: the Texas property you live in as your primary residence, which carries special constitutional protections.
• Non-homestead: any Texas property you do not live in, such as a rental, a second home, or a vacant tract you hold for income.
• Contributory land value: how much of a property’s appraised value comes from the land rather than the buildings.
• DSCR: debt service coverage ratio, which compares a property’s rent to its monthly obligation (principal, interest, taxes, insurance and any association dues).

Why Doesn’t Texas’s 80% Cap Apply to Your Rental?

The 80% limit protects homesteads, not rentals. The Texas A&M Real Estate Research Center explains that Texas home-equity loans under Section 50(a)(6) of the state constitution cannot exceed 80% of the home’s fair market value, counting all other debt on it. The same article says these loans cannot be taken on a secondary residence or on a rental or investment property.

So a rental tract sits outside the constitutional cap. That does not mean you can borrow without limit. The ceiling becomes whatever the lender’s investment-property program allows, and that is lower than 80%.

Market surveys point the same direction. BiggerPockets reports that most lenders offer 75%–80% LTV on rental properties. That is a market-wide figure, not a Lendmire network figure. On the network Lendmire places investment lines through, the ceiling is 70% CLTV, with no higher tier. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.

Many consumer sites blur this and say Texas investment-property equity loans reach 80%. Treat that as the homestead cap leaking into rental advice.

How Do You Calculate What You Can Borrow?

Start with a valuation and subtract what you already owe. The room you have is:

Value × 70% − first mortgage − every other lien = available room

Then two program limits apply. The line cannot exceed $500,000, and it cannot be smaller than $25,000. If your room falls under $25,000, there is nothing to write. The full credit limit counts toward CLTV whether you draw it or not.

Here are three modeled scenarios. Each uses percentages of your own value estimate, not dollars.

1. A standard rental, owned with a first mortgage. Say existing liens equal 50% of value. At a 70% ceiling, the room is 20% of value. Whether that clears the $25,000 minimum depends on the property’s value.

2. An acreage rental with a valuation haircut. Say you believe the tract is worth 100% of your estimate. The valuation comes back at 85% because surplus acres add little. Liens equal 50% of your original estimate. Room is 70% of 85%, or 59.5%, minus 50%. That leaves 9.5% of your original estimate. The same liens cost you more than half your expected borrowing power.

3. A free-and-clear tract with high value. If value × 70% lands above $500,000, the maximum line governs. Extra value above that point does not produce a bigger line.

Run your own numbers before you apply. The calculator on this page gives an illustrative estimate only. It is not a quote or an approval.

What Does Acreage Change?

Acreage changes the valuation and the eligibility. It does not change the percentage.

Valuation. An investment line of $500,000 or less ordinarily uses an automated valuation model, and no traditional appraisal is typical. An automated model prices a rural tract off nearby sales. Acreage has fewer comparable sales and wide spreads in land value. That is where the haircut in the second scenario comes from. You can request a full appraisal in any case, and on odd parcels that may produce a fairer number.

Eligibility. On this network, Texas properties are limited to 10 acres. Agricultural zoning is not eligible. Manufactured homes, log homes, commercial and mixed-use properties are also not eligible. Barndominiums are not financeable through the network’s DSCR programs either, and a rental in that category should be run as a separate question. Lenders also review parcels listed for sale, or listed within the past 60 days, as ineligible in Texas.

Homestead law uses its own acreage test. FindLaw says Texas limits a rural homestead to 200 acres for a family and 100 for a single adult, and an urban homestead to 10 acres. Those limits matter when part of your land is your home. They are not the lender’s investment limit.

Which Parcels Count as a Homestead?

Classify the parcel first. Everything else follows from that.

If you live on the property as your primary residence, it is a homestead. On this network, a Texas primary residence caps at 80% combined loan-to-value. The 12-day waiting period, the one-lien-at-a-time rule, and 12-month seasoning are homestead restrictions that bind primary residences only. A Texas second home or investment property is eligible as a non-homestead transaction and does not carry those restrictions.

Mixed parcels need care. Say your house and a rented cabin sit on one deed. Lenders can treat the home portion under homestead rules. Fannie Mae’s Selling Guide is a useful contrast here. It limits Texas 50(a)(6) loans to a single-unit homestead and asks for a survey showing the mortgaged homestead is a separate parcel when adjacent land is owned. DSCR files do not follow that guide, but the survey logic shows why splitting a parcel matters.

Do not label a lived-in tract as a rental to reach a different product. A law-firm article from Doss Law says a homestead cash-out written as a business-purpose loan would be a constitutionally noncompliant, unenforceable lien, and that homestead status requires a person, not an entity. If the history of the tract is unclear, ask a Texas attorney and your title company before you apply.

Who Qualifies for the Line?

An investment HELOC qualifies the borrower, not the rent. That is the main difference from a DSCR loan.

• Credit: the minimum is 700 on an investment property. A 720 score reaches the same 70% CLTV.
• Debt-to-income: 50% maximum. The lender calculates it on the interest-only payment at the maximum draw, which is more conservative than it sounds.
• Title: the property must be held by an individual or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind or land trusts cannot hold title. A property already deeded to an LLC needs a vesting change or a different product.
• Draw structure: a standalone line in first or second lien position. Investment lines run a 5-year interest-only draw followed by a 25-year repayment, with at least 75% of the line drawn at closing. The line does not convert to a fixed structure.
• Property type: single-family, 2-4 unit, PUD, townhome and condominium, including non-warrantable condos.
• Exposure: a borrower is limited to three lines, and an owner with more than 15 financed properties is not eligible.

Eligibility is subject to lender guidelines, and every file is reviewed individually. The line is brokered through select wholesale partners in the 16 states where Lendmire offers full-service lending, Texas among them. That footprint is narrower than Lendmire’s 41-market DSCR footprint, which includes Washington, D.C.

If the rental sits in an LLC, Lendmire’s guide to investment-property HELOC rules for LLC-titled borrowers covers the vesting problem in more detail.

HELOC or DSCR Cash-Out: Which Fits Acreage?

Choose by first-mortgage terms, vesting and how the property earns. A HELOC leaves your first mortgage alone. A DSCR cash-out replaces it.

A DSCR cash-out qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Across the wholesale network, a coverage ratio of 1.00 is the usual starting point, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Credit typically runs around 660, with a 620 floor in parts of the network. Loans run up to $3,000,000 on standard programs (smaller balances available through select lenders), and reserves commonly sit near 6 months of PITIA, varying by lender, leverage and loan size.

Clearing 1.00 does not mean positive cash flow. Repairs, vacancy, management, utilities and capital expenses sit outside the calculation.

DSCR programs do not offer manufactured homes, log homes or barndominiums, so acreage does not change that answer. Agricultural zoning also falls outside what the network offers on these loans.

Which Mistakes Cost Texas Acreage Owners the Most?

• Using the 80% number. Plan around 70% CLTV on an investment line.
• Counting the whole tract as value. The valuation prices what comps support, not what you paid.
• Forgetting the minimum. Thin room under $25,000 means no line.
• Holding title in an LLC. Fix vesting before you apply, or move to DSCR cash-out.
• Ignoring zoning. Agricultural zoning is not eligible.
• Skipping the homestead question. If you live on part of the land, get the parcel split right.

The stronger play for a mixed or LLC-held tract is often a straight comparison of both products against your first-mortgage terms. For some owners it is a toss-up. For owners with a first mortgage they want to keep, the HELOC wins. For owners who want one new loan, the DSCR cash-out wins.

Next Step

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. Reach the team at 828-256-2183. Program details are subject to lender guidelines and are not a commitment to lend.

A tract with more acres is not a bigger line. It is a harder valuation, so price the land honestly before you count on the equity.
