If you own a second home in Texas — a lake house, a Hill Country retreat, a beach place on the coast — you may be able to tap its equity with a HELOC. And here’s something many Texas homeowners don’t realize: borrowing against a Texas second home actually works differently, and in some ways more flexibly, than borrowing against your primary Texas residence.
The reason comes down to a quirk of Texas law that most people — and even many lenders — don’t explain clearly. Understanding it can change how you approach accessing your second home’s equity.
The Texas Rule That Changes Everything
Texas is famous for having the strictest home equity laws in the country. Those rules come from Section 50(a)(6) of the Texas Constitution, and they impose things like an 80% borrowing cap and various borrower protections.
But here’s the key point that gets lost in most discussions: those constitutional restrictions apply only to your primary residence — your Texas homestead.
Second homes and investment properties in Texas are not subject to the Section 50(a)(6) constitutional home equity rules. That means a HELOC on your Texas second home is treated as a traditional home equity product, following standard lending guidelines rather than the special constitutional homestead framework that governs your primary residence.
This is a genuinely important distinction, and it’s one we cover in depth for primary residences as well. Your homestead is the constrained asset. Your second home is the more flexible one.
What This Means for You in Practice
Because your Texas second home isn’t bound by the homestead constitutional rules, a second-home HELOC in Texas functions much like a second-home HELOC anywhere else in the country.
That means it follows standard second-home lending guidelines rather than the Texas homestead framework. You’re working within conventional rules for non-primary properties — the same rules a lender would apply to a vacation home in any state — rather than the specialized constitutional restrictions unique to Texas homesteads.
For many second-home owners, this is welcome news. The property you use for weekends and getaways is treated under a more familiar, standard set of rules.
How Much Can You Borrow on a Texas Second Home?
On a second home, the maximum combined loan-to-value is typically capped around 80% — meaning your existing mortgage plus the new HELOC generally can’t exceed 80% of the home’s value.
Here’s how the math works:
- Second home value: $500,000
- 80% ceiling: $400,000
- Existing mortgage on second home: $250,000
- Maximum available HELOC: $150,000
So on a $500,000 Texas second home with a $250,000 mortgage, you could potentially access up to $150,000, subject to your credit and income qualifying. If the second home is a condo rather than a single-family home, the CLTV cap is often somewhat lower, reflecting the additional risk considerations condos carry. Understanding your equity position before applying helps set realistic expectations.
Why Second Homes Have Stricter Qualifying
While Texas second homes escape the constitutional homestead rules, they still face something all second homes face nationally: stricter qualifying than a primary residence.
Lenders view second homes as higher risk, because a borrower under financial stress is more likely to prioritize the home they live in every day. That risk shows up as:
- A lower maximum CLTV than a primary residence
- Stronger credit requirements — often a higher minimum score
- Tighter debt-to-income limits
- Cash reserve requirements — you may need to show several months of combined payments in reserve
- Proof it’s a genuine second home, not a rental in disguise
That last point matters: a true second home and an investment property are underwritten differently, with investment properties facing even tighter limits.
HELOC or Home Equity Loan for a Texas Second Home?
Both products are available on a Texas second home, and neither is bound by the homestead constitutional rules.
A HELOC gives you flexible, revolving access — good for phased projects or ongoing needs. A home equity loan gives you a fixed lump sum with predictable payments — good when you know exactly how much you need. The same HELOC vs. home equity loan tradeoffs apply here, within the second home’s 80% CLTV limits.
Real Borrower Scenario
A Texas homeowner who owned a lake house on the water came in wanting to renovate it and build a boat dock. The property was worth around $480,000 with an existing mortgage of $230,000, and she wanted to leave her primary residence’s low-rate mortgage completely untouched.
She had assumed the strict Texas 80% homestead rules and various constitutional restrictions would apply, and was bracing for a complicated process. But because the lake house was a second home — not her homestead — those constitutional rules didn’t apply at all. It was treated as a standard second-home HELOC.
Running the second-home CLTV cap of 80%:
- $480,000 × 80% = $384,000 maximum total borrowing
- $384,000 − $230,000 existing mortgage = $154,000 available
That comfortably covered her renovation and dock. Her credit was strong, she had solid reserves, and the property was clearly a genuine second home she used seasonally — so it qualified cleanly. She was pleasantly surprised that her second home was actually the more flexible asset compared to her primary Texas residence.
Ready to Tap Your Texas Second Home’s Equity?
A HELOC on a Texas second home lets you access your vacation or seasonal property’s equity — typically up to 80% CLTV — under standard lending rules rather than the strict constitutional framework that governs your primary Texas homestead. For qualified borrowers, it’s a flexible, practical option.
