Investing Outside the Core: Top Austin MSA Secondary Markets for Multifamily Capital

Austin’s core submarkets continue to attract institutional capital, but compressed cap rates, elevated acquisition basis, and rising operating costs have pushed many multifamily investors to look outward. The opportunity increasingly sits in Austin MSA secondary corridors—especially Caldwell County, Lockhart, and nearby Guadalupe County—where metro spillover, workforce housing demand, and comparatively manageable tax environments can support stronger cash-flow underwriting.

This guide outlines how investors can evaluate these corridors, what makes them different from core Austin, and why local market access matters when sourcing and underwriting deals outside the urban core.

Why Investors Are Looking Beyond Central Austin

Austin added more than 58,000 residents between 2023 and 2024, a 2.3% increase, while Travis County grew 1.2%. Caldwell County, just southeast of Travis County, grew 4.6% during the same period—roughly twice the metro rate and among the fastest-growing counties nationally for jurisdictions with populations above 20,000.

That growth pattern matters for multifamily investors because population movement typically precedes housing demand. As home prices and rents in central Austin remain elevated, households increasingly seek lower-cost ownership and rental options within commuting distance of employment centers.

For investors, the trade-off is straightforward:

Investment factor	Core Austin	Secondary MSA corridors
Acquisition basis	Typically higher	Often lower
Cap-rate environment	More compressed	Potentially wider
Tenant demand	Deep but competitive	Growing, workforce-driven
Property taxes	Material operating expense	Varies by jurisdiction
Competition	Institutional and private capital	Often less crowded
Underwriting complexity	Established data sets	Requires stronger local diligence

Texas has no state-level property tax; property taxes are set and collected by local governments, so county, city, school district, and special-district levies can materially affect multifamily net operating income. That makes tax diligence a core part of underwriting—not an afterthought.

Caldwell County: Growth Beyond the Southern Edge

Caldwell County has become one of the most compelling secondary-market stories in the Austin MSA. The county’s population was estimated at about 55,200 in 2025, and its recent growth has been driven in part by households seeking more affordable housing alternatives near the Austin employment base.

Caldwell County’s growth is not merely a continuation of Austin’s expansion; it reflects a distinct affordability and land-availability dynamic. Investors should evaluate it as a workforce-housing market with its own employment, infrastructure, and household-formation trends rather than assuming it will behave like a direct extension of Travis County.

Key underwriting questions include:

• What share of residents commute toward Austin, San Marcos, or local employers?
• How much new multifamily supply is planned or under construction?
• Are rents supported by household income growth or primarily by short-term migration?
• What are the county, municipal, school-district, and special-district tax burdens?
• How resilient is demand if Austin’s job growth slows?

Lockhart: A Case Study in Workforce-Housing Demand

Lockhart, the Caldwell County seat, illustrates why secondary corridors can attract multifamily capital. The city’s population was 14,379 at the 2020 Census, but later estimates placed it around 17,146 in 2024—a 19.2% increase from the Census count.[post-register]

Lockhart’s demographic profile supports rental demand: its largest age cohort is 25 to 39, and the Lockhart Economic Development Corporation reports a median age of 38.8 and a median household income range of $50,000 to $75,000 for a meaningful share of residents. These are classic indicators for workforce rental housing: employed households, family formation, and demand for practical, well-located multifamily product.

For investors, Lockhart may offer a different risk-return profile than central Austin:

• Lower basis: Land and existing asset pricing can be more attainable than in core Austin.
• Workforce demand: Rental demand is tied to local households and regional commuters, not solely lifestyle-driven urban migration.
• Supply discipline: Smaller markets may have less new multifamily construction, though investors must verify pipeline data locally.
• Operational leverage: Effective management, expense control, and tax strategy can have an outsized impact on returns.

The key is not to assume every growing town supports institutional-quality multifamily. Investors should distinguish between population growth caused by housing affordability, employment access, infrastructure investment, and short-lived migration cycles.

Property Taxes: A Central Underwriting Variable

Property taxes are one of the most important variables in Texas multifamily underwriting. Travis County’s median effective property tax rate has been reported at 1.30%, while Guadalupe County’s countywide rate has been reported at 1.28% in one tax calculator dataset.

Those figures should be treated as starting points rather than deal assumptions. Actual taxes depend on assessed value, exemptions, improvements, taxing jurisdictions, and annual rate changes. Travis County’s own rate, for example, increased from 37.5845 cents to 38.621 cents per $100 of taxable value in its latest budget cycle.

For multifamily underwriting, investors should model:

• Current assessed value and anticipated reassessment after acquisition
• County, city, school, and special-district levies
• Potential protest strategy and appeal history
• Insurance, utilities, turnover, and maintenance alongside taxes
• Sensitivity cases for tax increases, rent growth, and vacancy

A lower headline tax rate does not automatically produce a better investment. A market with modestly higher taxes but stronger rent growth, lower vacancy, and better employment fundamentals can outperform a low-tax market with weak demand.

How Local GPs Source Secondary-Market Deals

Secondary-market investing requires more than scanning public listings. The best opportunities often emerge through broker relationships, off-market outreach, municipal planning insight, and granular knowledge of submarket rent and expense trends.

That is where local sponsorship matters. While national sponsors may analyze Texas from a distance, experienced Austin real estate investment firms leverage boots-on-the-ground market access to identify mispriced workforce assets across expanding Austin MSA secondary corridors.

A disciplined local underwriting process typically includes:

1. Submarket mapping: Identify corridors with employment access, population growth, infrastructure investment, and rental-demand indicators.
2. Asset-level diligence: Review rent rolls, delinquency, unit mix, deferred maintenance, and historical operating expenses.
3. Tax and insurance modeling: Build conservative assumptions for reassessment, insurance premiums, and operating-cost inflation.
4. Supply analysis: Confirm planned projects, entitlements, and construction timelines that could affect lease-up.
5. Exit planning: Evaluate both refinancing and sale scenarios under conservative rent and cap-rate assumptions.

Investment Thesis: Follow Demand, Not Headlines

The strongest Austin MSA secondary-market thesis is not simply “Austin is growing, therefore every nearby county is a good investment.” It is more specific: identify corridors where affordability, employment access, household formation, and limited near-term supply converge.

Caldwell County and Lockhart fit that profile because they combine rapid population growth with a workforce-oriented demographic base. Caldwell County’s 4.6% recent annual growth and Lockhart’s estimated 19.2% population increase since 2020 suggest meaningful demand pressure beyond Austin’s core.

For investors evaluating multifamily opportunities in the Austin MSA, the practical question is no longer only “Which Austin neighborhood has the best location?” It is also: Which secondary corridor offers durable workforce demand at a basis that supports cash flow?

Final Takeaway

Secondary corridors such as Caldwell County, Lockhart, and Guadalupe County can offer multifamily investors an alternative to core-Austin cap-rate compression. But these markets reward operators who understand local taxes, employment drivers, supply pipelines, and tenant demand—not investors relying solely on metro-level headlines.

For sponsors and private-equity investors, the advantage lies in pairing regional growth data with local execution: sourcing assets early, underwriting taxes conservatively, and managing workforce housing with an operating plan built for the specific submarket.

Detailed Fact-Check Notes

Austin MSA & County Growth Metrics:

• Claim: Austin added over 58,000 residents between 2023 and 2024 (a 2.3% increase), while Travis County grew 1.2% and Caldwell County grew 4.6%.
• Fact Check: Accurate. U.S. Census Bureau estimates confirmed that Caldwell County surged by roughly 4.6% (adding over 2,300 residents) during that specific window, making it one of the fastest-growing counties nationwide for its population tier.

Lockhart Population Data:

• Claim: Lockhart’s population grew from 14,379 (2020 Census) to an estimated ~17,146 in 2024 (a ~19.2% increase).
• Fact Check: Mixed / Nuanced. While the 2020 decennial census count for Lockhart was 14,379, various ACS datasets and local estimates place current figures around 15,300 to over 17,000 depending on the specific multi-year survey release or extra-territorial jurisdiction (ETJ) inclusions used by local economic groups. The growth trajectory itself is solidly supported, though the precise 19.2% figure leans toward local economic development projections rather than a strict baseline Census count.

Tax and Underwriting Premise:

• Claim: Texas has no state-level property tax, and rates are dictated by a patchwork of county, city, school, and special districts that heavily impact Net Operating Income (NOI).
• Fact Check: Accurate. This is a vital baseline point for Texas commercial real estate underwriting. Special utility districts (MUDs/PIDs) and school district I&S/M&O rates create wide tax deltas between core cities and outer secondary corridors.
