HELOC in Texas: Rules, Limits, and How to Qualify

How HELOCs Work in Texas: The Constitutional Framework

Texas home equity lending operates under a unique constitutional framework that doesn’t exist in any other state. Article XVI, Section 50 of the Texas Constitution governs all home equity lending, and its provisions create meaningful differences from how HELOCs work in other states. Before applying for a HELOC in Texas, understanding three key constitutional constraints shapes your planning:

The 80% combined LTV ceiling: Texas prohibits any home equity debt — first mortgage plus HELOC plus any other liens — from exceeding 80% of the property’s appraised value. On a $450,000 home with a $280,000 first mortgage (62% LTV), the maximum home equity debt is $450,000 × 80% = $360,000. Your HELOC maximum is $360,000 – $280,000 = $80,000. You cannot exceed this regardless of creditworthiness or lender willingness. This is a constitutional limit, not a lender’s underwriting preference.

The 12-day waiting period: Texas requires a 12-day cooling-off period between the date the lender provides the required disclosure documents and the date the loan can close. This applies to every Texas HELOC and home equity loan — including refinances and modifications. There are no exceptions. If you need funds in 10 days for a closing, a Texas HELOC cannot accommodate that timeline. Plan accordingly.

The one-year waiting period after a prior home equity loan: Texas homeowners cannot take out a new home equity loan within 12 months of closing a prior home equity loan on the same property. Back-to-back HELOCs within a year are prohibited constitutionally. If you closed a HELOC in February 2024, you cannot close a new HELOC on the same property until after February 2025 regardless of any changes in your equity position or financial circumstances.

Texas HELOC vs. Cash-Out Refinance: When to Choose Each

Texas homeowners considering accessing equity have two primary options: a HELOC (revolving line of credit secured by home equity) or a cash-out refinance (replacing the existing first mortgage with a new, larger first mortgage). The right choice depends on several variables:

Choose a HELOC when: You need flexible access to funds over time rather than a lump sum upfront. A HELOC allows you to draw funds as needed up to your credit limit during the draw period, repay, and re-draw — functioning like a credit card secured by your home. For ongoing renovation projects where you’ll draw funds as contractors complete phases, a HELOC matches the spending pattern. You also preserve your existing first mortgage rate — critical if your current rate is significantly below today’s market rates. A homeowner with a 3.5% first mortgage rate from 2021 should strongly prefer a HELOC over a cash-out refinance, which would replace the low-rate first mortgage with a new mortgage at today’s 7%+ rates.

Choose a cash-out refinance when: You need a large lump sum and your existing rate is already near current market rates. A cash-out refi combines the cash access and the first mortgage into one product at a single rate. If you’re going to access $100,000 in equity and your current rate is 6.75% and today’s rate is 7.00%, the cash-out refinance adds only 0.25% to your rate while giving you $100,000 — a much smaller rate-change cost than what someone with a 3.5% existing rate would face. The simplicity of one loan, one payment, one servicer is also an administrative advantage over maintaining a first mortgage plus a HELOC.

How Texas HELOC Rates Are Priced

HELOC rates are typically variable, tied to the Prime Rate published by the Federal Reserve. The standard structure: Prime Rate + a margin set by the lender, typically 0.25% to 2.00% depending on creditworthiness and LTV. As of 2025, with Prime Rate at 7.50%, a borrower with 740 FICO and 60% CLTV might receive Prime + 0.25% = 7.75%. A borrower with 680 FICO and 75% CLTV might receive Prime + 1.50% = 9.00%.

Some Texas HELOC products offer a fixed-rate option for all or part of the drawn balance — allowing you to lock a portion of your draw at a fixed rate while keeping the remainder variable. For large draws (over $50,000) you expect to hold for 5+ years, the fixed-rate option provides payment predictability in exchange for a slightly higher rate than the variable option at any given point.

Texas HELOCs typically have three phases: the draw period (commonly 10 years during which you can draw and repay flexibly, with interest-only minimum payments), the repayment period (commonly 20 years during which the balance amortizes — minimum payments increase significantly because you’re now paying principal plus interest), and some products include a balloon structure requiring full payoff at draw period end rather than a repayment period. Understand which structure your HELOC uses before signing — the difference between interest-only during draw period and fully amortizing during draw period meaningfully affects your cash flow during the draw years.

HELOC Qualification Requirements in Texas

Texas HELOC qualification uses similar metrics to mortgage qualification — lenders evaluate your credit score, DTI including the new HELOC payment, and the property’s appraised value:

Credit score: Most Texas HELOC lenders require 620 minimum; 680 is the comfort zone for competitive pricing; 720+ for best rates and maximum LTV. Below 660, some lenders decline or require lower CLTV to compensate.

Combined LTV (CLTV): Lenders typically prefer CLTV below 80% (which aligns with Texas’s constitutional limit), and some set internal limits of 70–75% CLTV for competitive pricing. Your CLTV = (first mortgage balance + HELOC limit) ÷ appraised value. The appraiser’s value, not your tax assessment or an automated estimate, governs — expect an appraisal to be ordered.

DTI including HELOC payment: Lenders calculate DTI using the fully-drawn HELOC payment (what you’d owe if you drew the full line). This conservative approach ensures you can service the maximum potential debt. A $100,000 HELOC at 8.5% interest-only = $708/month drawn. Add this to your existing PITI and other obligations to confirm the combined DTI is within program limits.

Debt service on the HELOC: During the draw period, interest-only minimum payments don’t trigger new required principal payments. This makes the qualifying payment calculation more manageable than if principal amortization were required immediately.

Legitimate Uses That Justify Home Equity Access

Texas law has traditionally restricted and scrutinized home equity lending more than most states — rooted in the historical “homestead protection” principle of Texas law. The constitutional framework reflects an underlying premise: your home should be the last asset deployed for general consumption, not the first. This philosophy is worth taking seriously even where the law permits borrowing.

Uses that generate financial return — home improvements that increase market value (kitchen and bath renovations, additions, energy efficiency upgrades), debt consolidation that reduces total interest cost by replacing high-rate revolving debt with lower-rate home equity debt, or investment in a business with positive return potential — are the cases where home equity access is financially defensible.

Uses that generate no financial return — consumer goods, vacations, vehicles, general lifestyle consumption — are where the risk-adjusted case for using home equity is weakest. Your home equity is a reserve against housing security, not a revolving spending fund. A HELOC used for a $45,000 kitchen renovation on a home that would sell for $60,000 more afterward is a defensible financial decision. A HELOC used to fund annual vacation and consumer purchases is trading long-term home equity security for short-term spending flexibility in a way that compounds risk to your housing stability.
