Texas HELOC Guide & Calculator

Everything Houston homeowners need to know about tapping home equity in Texas — including the state’s unique constitutional rules.

How Houston Homeowners
Use Their Equity

Houston’s strong home appreciation means many homeowners are sitting on significant equity. Here’s how our clients put it to work:

🏊
Pool & Outdoor Living
Houston summers make a pool a near-necessity. A HELOC is one of the most popular ways to finance a new pool, outdoor kitchen, or covered patio.
🎨
Home Renovation
Kitchen remodels, primary suite additions, and whole-home updates. Draw what you need as your project progresses.
🌿
Landscaping & Hardscaping
Transform your yard with professional landscaping, drainage solutions, and outdoor entertainment spaces.
💳
Debt Consolidation
Pay off high-interest credit cards or personal loans with a significantly lower HELOC rate.
🎓
Education Expenses
Fund college tuition or private school costs at home equity rates rather than student loan rates.
🏠
Down Payment on Investment
Use your primary home’s equity as a down payment on a rental property or investment opportunity.

This calculator provides estimates based on Texas’s 80% combined LTV constitutional cap (Article XVI, Section 50). Actual HELOC availability depends on your lender’s appraised value, credit score, debt-to-income ratio, and other underwriting criteria. This is not a commitment to lend.

What is a HELOC?

A Home Equity Line of Credit (HELOC) lets you borrow against the equity you’ve built in your home — similar to a credit card, but secured by your property. You’re approved for a maximum credit line, and you draw from it as needed during the draw period (typically 10 years), paying interest only on what you use. After the draw period ends, you enter the repayment period and pay back principal plus interest.

Because your home secures the loan, HELOC rates are significantly lower than credit cards or personal loans — making it one of the most cost-effective ways for homeowners to fund large projects, consolidate debt, or create a financial safety net.

Texas is unique. Texas has the strictest home equity lending rules in the country, enshrined in Article XVI, Section 50 of the Texas Constitution. Before you apply, you need to understand what’s different here.

🤠 Texas HELOC Rules — What Makes Texas Different

📐

80% LTV Cap — Constitutional

Your first mortgage + HELOC cannot exceed 80% of your home’s appraised value. This is a constitutional limit — no lender can exceed it regardless of creditworthiness. You must always retain at least 20% equity.

1️⃣

One Loan at a Time

Texas allows only one active home equity loan or HELOC per property at a time. You cannot have a HELOC and a home equity loan simultaneously on the same homestead.

⏳

12-Day Cooling-Off Period

You must wait at least 12 days after applying before closing on a Texas HELOC. This is a constitutional right — it cannot be waived.

🏢

Closing Location Required

Texas HELOCs must close at a lender’s office, attorney’s office, or title company. You cannot close at your home or other locations.

💰

Fees Capped at 2%

Lender fees on a Texas home equity loan or HELOC are capped at 2% of the loan amount — not including third-party costs like appraisal or title.

🔄

Annual Zero-Out Requirement

Texas HELOCs require the borrower to reduce the outstanding balance to zero at least once per year. This is unique to Texas and not required in other states.
