Texas Industrial Investment Report Q2 2025: A Data-Driven Analysis of the Austin-San Antonio Corridor

Executive Summary

For the discerning investor attempting to decipher the Central Texas industrial market, a cursory glance at the headline reports for Austin and San Antonio presents a confounding picture. In Austin, the narrative is one of a market absorbing a historic wave of new supply, with vacancy rates climbing past 12% even as its tech and manufacturing sectors signal long-term strength. Ninety miles to the south, San Antonio appears to be a model of stability, with single-digit vacancy and a more measured development pipeline, yet it lacks the explosive rent growth that has characterized the region.

A superficial analysis might lead to a simple, yet fundamentally flawed, conclusion: Austin is overbuilt, and San Antonio is stagnant. Both assessments miss the real story. The most dynamic, opportunity-rich industrial market in Texas—and arguably the nation—is not found within the urban cores of these metros, but in the explosive 80-mile corridor of growth that connects them. However, a complete analysis cannot stop at the I-35 spine. This report moves beyond the high-level summaries to provide the granular, on-the-ground intelligence that institutional reports often overlook. We dive deep into the industrial markets of Comal, Hays, and Guadalupe counties, and then expand our focus to the often-overlooked but increasingly critical US-281 and SH-46 corridors. These secondary arteries are creating new nodes of development and present a fertile ground for specific asset classes, most notably small-bay and flex industrial space. This analysis offers a clear, actionable playbook for investors seeking to capitalize on every facet of Central Texas’s unprecedented growth.

Part I: The Macro-Economic Landscape – The Engine of a Megaregion

To understand the opportunity in the I-35 corridor, one must first appreciate the powerful national and global trends that are funneling capital, talent, and commerce directly into Central Texas. This is not merely a local boom; it is the physical manifestation of a fundamental reordering of the North American economy.

The most significant driver is the creation of a true “megaregion” stretching from Georgetown to South San Antonio. This corridor is now home to nearly 5 million people, a figure projected to swell to almost 7 million by 2030. This demographic super-cycle, fueled by both domestic migration and international immigration, creates a compounding effect on commercial real estate. Every new household requires goods and services, driving demand for logistics, warehousing, and the last-mile delivery infrastructure needed to support them.

This population growth is occurring in lockstep with a strategic realignment of the continent’s supply chains. The push for nearshoring and reshoring manufacturing from overseas has made Texas, with its central location and proximity to Mexico, a primary beneficiary. The I-35 corridor, already the nation’s busiest inter-metro freight route, serves as the main artery for this new wave of trade. This has created immense demand for modern industrial facilities, from massive distribution centers to specialized manufacturing plants.

Recognizing the critical importance of this corridor, state and local governments are making generational investments in infrastructure, effectively de-risking the market for private investors. The I-35 NEX Program, a multi-phase expansion, and the massive $1.4 billion widening of SH 46 are not just road projects; they are billion-dollar catalysts for commercial development. These projects are designed to alleviate the strain on a route ranked as the 4th most congested interstate in the United States, unlocking previously inaccessible land parcels and dramatically improving logistics efficiency for businesses operating within the corridor. For an investor, this public spending is the ultimate market validator, signaling long-term commitment and underwriting the region’s future growth.

Part II: The Tri-County Deep Dive – A Comparative Data Analysis

The true story of the I-35 corridor is not monolithic. It is a mosaic of three distinct county-level markets, each with its own unique profile of risk, opportunity, and momentum. By analyzing them side-by-side, a much clearer investment thesis emerges.

¹ Data for Hays County is from a combined report including Bastrop and Caldwell counties.

² Data for Guadalupe County is based on the broader San Antonio Metro report.

On-the-Ground Intelligence: What the Numbers Really Mean

Data without context is just noise. Here’s our analysis of what’s happening on the ground in each county and where the opportunities lie for the informed investor.

Comal County: A Strategic Supply Wave Creates Opportunity

At first glance, a 10.6% industrial vacancy rate might seem concerning. However, for Comal County, this figure is not a sign of market weakness but rather a signal of a massive and necessary market evolution. Over the past year, 930,000 square feet of new industrial space came online, a significant addition that temporarily outpaced the 400,000 square feet of absorption.

This is not speculative excess; it is the market building the capacity to meet a tidal wave of demand. Comal County’s population growth is among the highest in the nation, with New Braunfels being recognized as the second-fastest-growing city in the U.S.. This demographic explosion is creating intense demand across all commercial sectors. The arrival of bellwether brands like Costco, Topgolf, and Portillo’s—companies with famously rigorous, data-driven site selection processes—serves as a powerful third-party endorsement of the region’s long-term economic trajectory.

The current vacancy is heavily concentrated in large, newly constructed logistics facilities (12.8% vacancy), while the smaller flex space market remains exceptionally tight at just 4.9% vacancy. This bifurcation presents a clear strategic window. For investors, the temporary market softness in the big-box sector is an opportunity to acquire Class A assets before the next wave of demand—driven by the very growth these new developments were built to serve—fills this new inventory and drives prices upward.

Hays County: The Epicenter of Austin’s Gravitational Pull

Stretching from San Marcos north to Kyle and Buda, Hays County is feeling the direct gravitational pull of the Austin metro area. The county is a primary pressure-release valve for Austin’s explosive growth, attracting businesses and residents seeking more affordable real estate and a business-friendly environment. This dynamic is reflected in the investment data: with a market cap rate of 7.9% and an average sale price of $120 per square foot, capital is actively being deployed here.

The market is in the midst of a historic development boom, with over 2 million square feet of new industrial facilities recently delivered or under construction in the city of Kyle alone. This has pushed the submarket’s overall vacancy rate to a high of 14.9%. While this figure appears elevated, it is largely a function of the sheer volume of new speculative space hitting the market simultaneously. Demand remains robust, with the submarket posting an impressive 2.3 million square feet of positive net absorption year-to-date. For developers and investors, Hays County represents the leading edge of Austin’s southward expansion, offering opportunities to serve a rapidly growing population and a diverse tenant base that ranges from last-mile distribution to advanced manufacturing.

Guadalupe County: The Next Frontier of Industrial Development

While granular data for Guadalupe County is often rolled into the broader San Antonio metro reports, the qualitative signs on the ground point to it being the next major frontier for industrial growth. The county’s strategic location at the intersection of I-35 and I-10 makes it a critical future hub for regional distribution, connecting the Austin-San Antonio corridor with Houston and the Gulf Coast.

Developers are taking notice. The city of Schertz is aggressively developing large-scale industrial parks like Park 35, and developers are actively acquiring land for new flex-industrial projects in Seguin, citing it as an “underserved submarket”. The San Antonio metro report, which includes Guadalupe County, shows a healthier vacancy rate between 8.6% and 9.9% and a massive 6.1 million square feet of space currently under construction, indicating strong forward-looking momentum. With a market cap rate of 7.2%, slightly compressed compared to Hays County, investors are pricing in the area’s strategic importance. For investors with an eye for land acquisition and build-to-suit opportunities, Guadalupe County offers the chance to get in on the ground floor before the market fully matures.

Part III: Submarket Spotlight & Product Type Analysis

A truly sophisticated investment strategy requires looking beyond county lines to the specific product types and sub-sectors that are driving performance. The I-35 corridor is not a homogenous market; it is a collection of micro-markets, each with its own story.

The Bifurcation of the Market: Big-Box vs. Small-Bay

The most significant trend shaping the corridor is the clear bifurcation between large distribution centers and smaller flex/light industrial spaces.

The Rise of the “Big Box”: The national trend of e-commerce and supply chain optimization has led to a boom in the construction of large-scale logistics and distribution facilities (100,000+ SF). This is particularly evident in Comal and Hays counties, where much of the new supply and resulting vacancy is concentrated in this product type. While this has created a temporary oversupply and a tenant-favorable environment in the short term, these modern, high-clear-height facilities are precisely what large national distributors and manufacturers are seeking as they expand into Central Texas. The current market softness presents a rare opportunity for well-capitalized investors to acquire Class A assets at pricing that does not yet reflect the full long-term demand.

The Resilience of Flex & Small-Bay Industrial: In stark contrast to the big-box market, the small-bay industrial sector (properties under 50,000 SF) remains exceptionally tight. In Comal County, for example, flex space vacancy is a mere 4.9%.[12] Nationally, this product type has seen chronically low levels of new development, creating a persistent supply-demand imbalance. These properties are the lifeblood of the local economy, serving a diverse tenant base of contractors, local distributors, and service-oriented businesses that are directly benefiting from the region’s population boom. For investors, these assets offer stable cash flow, lower risk of long-term vacancy, and a direct play on the local growth story.

Land & Development: Where is the Smart Money Going?

The land market along the corridor is also telling a nuanced story. The frenzied, speculative land grabs of 2021 and 2022 have subsided. Today, builders and developers are far more selective, prioritizing certainty and speed to market.

Unentitled raw land has seen price reductions, as the costs and timelines associated with the entitlement process have become more challenging. Conversely, properties that are fully entitled, zoned for industrial use, and have utilities readily available are commanding a significant premium. The focus has shifted from speculative land banking to acquiring “shovel-ready” sites that allow for immediate development. This creates a clear opportunity for investors with the expertise and patience to navigate the local entitlement process. Acquiring well-located raw land and taking it through the zoning and permitting process can create substantial value in the current market environment.

Part IV: The Overlooked Arteries – Uncovering Opportunity Along the US-281 and SH-46 Corridors

While the I-35 corridor rightfully commands the lion’s share of attention, sophisticated investors know that the most compelling opportunities often lie just off the beaten path. Two such arteries—the US-281 corridor north of San Antonio and the SH-46 corridor running east-west—are rapidly evolving from secondary routes into critical economic lifelines. These corridors are creating new nodes of development and present a fertile ground for specific asset classes, most notably small-bay and flex industrial space, that are underserved by the large-scale development focused on I-35.

The US-281 Corridor (Bulverde/Spring Branch): The Affluent Frontier and the Demand for Flex Space

Stretching north from San Antonio through the rolling hills of western Comal County, the US-281 corridor, encompassing communities like Bulverde and Spring Branch, represents the region’s affluent suburban frontier.[14] This area is a magnet for high-earning families and professionals drawn by its scenic beauty and top-rated school districts. This demographic is not just building luxury homes; it is creating powerful, localized demand for a specific type of commercial real estate.

The primary catalyst for this submarket is the ongoing expansion of US-281 itself. Identified as one of Texas’s most congested corridors, the multi-phase project is converting the highway into a controlled-access freeway, vastly improving mobility and connectivity to San Antonio. This infrastructure investment is unlocking the commercial potential of adjacent land, creating opportunities for developers who understand the unique needs of the local population.

The demand here is not for massive distribution centers, but for high-quality flex space. The affluent residents of Bulverde and Spring Branch require a robust ecosystem of local services: high-end home builders, specialized contractors, medical and dental practices, and professional services like wealth management and law offices. These businesses need functional, modern spaces that combine a professional office front with a small warehouse or workshop component for storage and light operations. This is the definition of flex space, and the demand is currently outpacing the available supply.

Development in this corridor requires navigating a complex local regulatory environment. The City of Bulverde, for instance, has specific zoning districts (C-1, C-2, C-3 for commercial and I-1 for industrial) that dictate everything from permitted uses to building materials and setbacks. This complexity, managed by entities like the Bulverde/Spring Branch Economic Development Foundation, creates a significant barrier to entry for out-of-town developers, giving local experts with established relationships a distinct competitive advantage. For the savvy investor, this presents a clear opportunity: acquire well-located land, partner with local experts to navigate the entitlement process, and develop the exact type of flex space this underserved and affluent market is clamoring for.

The SH-46 Corridor (Boerne to Seguin): The East-West Connector Creating New Industrial Nodes

If I-35 is the region’s primary north-south artery, State Highway 46 is its increasingly vital east-west counterpart. This corridor is a strategic connector, linking I-10 in the burgeoning city of Boerne, crossing US-281 and I-35, and continuing to I-10 again in the manufacturing hub of Seguin. For years, it was a secondary highway. Today, it is the focus of a massive, $1.4 billion expansion project designed to transform it into a four-lane controlled-access highway.

This is not just a road-widening project; it is the creation of a new economic corridor that is opening up previously overlooked areas for industrial development. The improved connectivity is creating new industrial nodes at key intersections, and the primary opportunity for investors is, once again, in the flex space sector.

The investment thesis for SH-46 is built on its unique ability to connect diverse economic zones. It provides a crucial link between the high-growth residential communities of Boerne and Bulverde, the commercial center of New Braunfels, and the established industrial base of Seguin. This creates a powerful demand for flex and light industrial properties from a wide range of tenants:

Suppliers and Service Providers: Businesses that support the major manufacturers in Seguin (like Caterpillar and Continental) and the distribution centers along I-35 need smaller, strategically located facilities along SH-46 for rapid access to their clients.

Construction and Trades: The explosion of residential development in communities like Boerne and Spring Branch requires a network of plumbers, electricians, and other contractors who need workshop and storage space.

Last-Mile Distribution: As the population grows along the entire corridor, so does the need for smaller distribution points to facilitate last-mile delivery.

Proof of this thesis is already materializing. In early 2025, Partners Development announced the acquisition of 20 acres in Seguin specifically to develop multiple flex-industrial buildings, citing the area as a “rapidly growing and underserved submarket”. This move by an experienced developer is a clear market signal that the demand for smaller, flexible industrial space along the SH-46 corridor is real and growing.

Part V: The Investor’s Playbook – Actionable Strategies for Q3/Q4 2025

For Landlords & Sellers: The current market is highly dependent on your asset type. If you own smaller, well-located flex or light industrial space, you are in a position of strength. Tenant demand is high, and supply is limited, allowing for strong rental rate growth and favorable lease terms. If you own a large, newly delivered but vacant warehouse, be prepared for a competitive lease-up period. Offering concessions and flexible terms will be crucial to attract tenants in the short term. However, the long-term fundamentals remain solid, so a strategic, patient approach to leasing will ultimately be rewarded.

For Investors & Buyers: This is a strategic acquisition window, but a targeted approach is essential. The temporary supply/demand imbalance in Comal County’s logistics sector offers a rare opportunity to acquire Class A assets without the intense competition we expect to see in 12-18 months. In Hays County, with its more mature development cycle, look for value-add opportunities in older, well-located assets that can be repositioned to serve the growing population. In Guadalupe County, land is the primary play. Securing well-located industrial-zoned land now will pay significant dividends as development continues to push east.

For the US-281 and SH-46 Corridors: The strategy here is laser-focused on flex space. Along US-281 in the Bulverde/Spring Branch area, target land parcels suitable for developing high-quality flex office/warehouse projects for service-based businesses catering to the affluent local demographic. Along SH-46, focus on land acquisition near key interchanges (I-10, US-281, I-35) for future flex and light industrial development, particularly in underserved markets like Seguin where development is already underway.

For Business Owners & Tenants: If you are a user looking to lease industrial space, particularly a larger footprint, you currently have more options and negotiating leverage than you’ve had in years. Landlords of new, large-scale projects are motivated to make deals to secure anchor tenants and stabilize their properties. This is an ideal time to lock in favorable long-term lease rates and generous tenant improvement allowances before the current supply wave is absorbed and the market inevitably tightens once again.

Conclusion

The I-35 corridor between Austin and San Antonio is not just a line on a map; it’s the most dynamic and strategically important economic artery in Texas. The data tells a clear story of growth, but the real opportunities are found by understanding the unique narrative of each county and each submarket. While the national headlines focus on the rebalancing of the Austin and San Antonio metros, the most compelling story for the savvy investor is happening in the spaces in between.

A complete picture of the region’s industrial market requires looking beyond the primary I-35 spine to the vital east-west and north-south arteries of SH-46 and US-281. It is here, in the affluent suburbs of western Comal County and along the newly expanding connectors, that the next wave of growth is taking shape. The demand for smaller, flexible industrial space in these overlooked corridors presents a powerful, underserved niche. By understanding these nuanced, hyper-local dynamics, investors can position themselves to capitalize not just on the growth that is happening today, but on the growth that is destined to happen tomorrow.
