Bexar County, TX Investment Property Analysis

The Honest Thesis

Bexar County is a cash-flow market in a buyer-friendly correction, with a secondary value-add angle for operators willing to work the ADU code. At a 15.6x price-to-rent ratio and a 6.42% gross yield on a $257,675 median home, this is not a market you buy for appreciation. It is a market you buy because entry prices are down from a 2022 peak of roughly $345,200, 55.6% of sales are closing below asking price, and a supply-side catalyst is forming as 2024 apartment starts collapsed 80% to 1,874 units, their lowest level since 2009.

The net-yield math is the central tension. A 6.42% gross yield sounds healthy against a national median well above $300,000, but Bexar County's all-in property tax rate runs 2.1%–2.3% and homeowners insurance premiums jumped 15%–25% since 2023. Strip those out, add a vacancy allowance against a current 7.2% single-family rental vacancy rate, and net cash-on-cash returns compress to something far thinner than the headline yield implies. Buyers who underwrite to gross yield will be disappointed. Buyers who model the actual cost stack and target the right submarkets can still find workable deals.

The supply tightening story is the medium-term thesis. With almost no new multifamily pipeline arriving in 2026–2027, existing landlords who are positioned now should see vacancy tighten and rent growth resume. That is the trade.

Demand Drivers: Who Is Renting in Bexar County

Employment Base

From 2018 to 2023, Bexar County added 51,774 jobs, growing at 5.1% against a national rate of 3.9%. The employer base is anchored by three recession-resistant categories: restaurants and food service, local government education and hospitals, and federal government and military. That mix is not glamorous, but it is durable. Renters tied to military installations and public sector payrolls do not disappear in a downturn.

The corporate recruitment pipeline adds incremental upside. Greater:SATX, the regional economic development partnership, brought in an average of 3,000 jobs and $1.1 billion in investment per year between 2022 and 2024, supporting over 500 company relocations or expansions that collectively employ more than 120,000 San Antonians. H-E-B is separately seeking a $15 million tax incentive from Bexar County to expand its Foster Road supply chain campus, with a commitment to 1,232 new full-time jobs by 2038, most of them on the south side of the county. San Antonio is also pursuing Toyota for a $2 billion vehicle assembly line, having offered a $142.8 million incentive package. A Toyota win would be a step-change employment event; it has not been awarded yet, so underwrite without it.

Port San Antonio and CyManII are cementing the area as a national cybersecurity hub, attracting higher-wage knowledge workers who support upper-tier rental demand. That sector diversifies a job base that has historically skewed toward government and service employment.

Submarket Analysis by Neighborhood

Southtown, Tobin Hill, and Dignowity Hill

These three inner-city neighborhoods carry the best combination of near-term rental demand and medium-term appreciation potential in the county. Southtown and Tobin Hill are identified as high-rental-demand areas with strong investor ROI and active revitalization. Dignowity Hill, adjacent to downtown, has seen Victorian-style home appreciation and an influx of developer activity on vacant lots. Properties inside Loop 1604 are holding value better than outer suburban corridors. Gross yields in inner-ring neighborhoods tend to run at the lower end of the 6%–8% submarket range, but vacancy risk is lower and tenant quality is higher.

West San Antonio and Harlandale

These submarkets offer gross yields at the upper end of the 6%–8% range. The trade-off is a lower-income renter pool and more management intensity. The H-E-B Foster Road expansion, if completed, adds a specific demand catalyst on the south side by 2038. Cash-flow buyers who can manage operations here or partner with a strong local property manager will find better initial yields than the inner-ring neighborhoods.

Stone Oak and Alamo Ranch (North and Northwest)

These are the appreciation corridors. Prices in Stone Oak and Alamo Ranch are showing growth while the east and southeast sides have dropped more than 20%. Gross yields on north-side properties will be at or below 6%, which makes them thin cash-flow plays at best. A buyer prioritizing long-term appreciation over current income has a case here, but the math needs to work on a longer hold period and with realistic assumptions about rent growth.

East and Southeast Bexar County

Prices have dropped more than 20% as of early 2026. That creates asymmetric entry opportunities, but investors need to underwrite higher vacancy and slower appreciation against those discounts. Do not buy the southeast because it is cheap. Buy it only if the specific cash flow math clears your hurdle rate at actual operating costs.

Underwriting Considerations

Property Taxes

The Bexar County rate sits at $0.299999 per $100 of assessed value, unchanged since 2021. The City of San Antonio adds $0.54159 per $100, also unchanged from 2024. Combined with the ISD levy, the all-in effective rate runs 2.1%–2.3%. On a $257,675 purchase, that is roughly $5,411–$5,927 per year in property tax before any exemptions. Residential assessed values rose only 2.1% for tax year 2025, but commercial and multifamily values rose 7.68% and 4.31% respectively, meaning apartment investors face steeper assessment growth.

The biennial appraisal freeze beginning in 2026 means successfully protesting your 2025 value locks that basis through 2026. File the protest.

The county faces a projected $145 million general fund deficit by FY 2029, driven partly by a $203 million drop in residential assessed value. Tax rates have been stable, but that fiscal gap raises the probability of rate increases in future budget cycles. Do not assume current rates persist for a ten-year hold.

Insurance

Homeowners insurance premiums rose 15%–25% since 2023, driven by hail and wind coverage. This is not recoverable from the tenant and must sit in your operating expense model. San Antonio's hail exposure is a structural cost, not a one-year anomaly.

Flood Risk

FEMA's draft maps for Bexar County show 5,639 buildings being added to flood hazard zones, using rainfall data that replaces estimates from the 1960s. The San Antonio River Authority mapped over 1,700 stream miles to produce these maps. Any property near a creek corridor or in a low-lying area carries regulatory risk until FEMA adoption is complete. Properties newly mapped into Special Flood Hazard Areas will face mandatory flood insurance on federally backed loans, directly increasing carrying costs and potentially reducing sale values. Verify current and draft FIRM panels before closing on anything in a transitional zone.

Landlord-Tenant Rules

Texas has no statewide rent control and no transfer tax. San Antonio has not enacted local rent control. The environment is landlord-friendly on rent-setting, lease enforcement, and eviction procedures. Short-term rental operators using ADUs must maintain owner-occupancy to comply with the current city ordinance.

Where to Buy by Investor Profile

Cash-Flow Buyer

Target West San Antonio or Harlandale at the upper end of the 6%–8% gross yield range. The H-E-B south-side expansion provides a long-dated demand catalyst. Buy below $250,000 in the sub-$300K segment that accounted for 40.3% of closed sales in 2025, which confirms a deep buyer and renter pool at that price point. Model the 2.1%–2.3% tax rate and insurance step-up before committing; the yield spread above expenses is workable but not wide.

Appreciation Buyer

Focus on Stone Oak or Alamo Ranch on the north side, or the gentrifying inner-ring neighborhoods (Dignowity Hill, Tobin Hill) where the Green Line BRT corridor along San Pedro Avenue creates a specific transit premium catalyst. Do not expect near-term price recovery; the correction from the 2022 peak of $345,200 is ongoing and inventory stands at 6.0 months with 17,131 active listings. Appreciation here is a 2028-and-beyond story tied to the supply tightening cycle and transit opening.

Value-Add Operator

The ADU (casita) framework is the most specific opportunity in this market. The 2022 UDC amendment already allows detached ADUs with separate utilities, removed the one-bedroom limit, and permits construction closer to property lines. The 2024–2025 UDC overhaul is pushing toward citywide ADU legalization up to 1,000 square feet with simplified permitting. An operator who buys a single-family asset in Southtown or Tobin Hill, adds a permitted casita, and leases both units captures incremental yield on a lot that was already purchased. Model conservative: ADUs over 800 square feet require one parking space under the current code.

Where the Puck Is Going

The supply picture is the clearest forward signal. With only 1,874 multifamily units starting in 2024, the pipeline into 2026–2027 is nearly empty. Vacancy at 7.2% and rents currently declining are the entry condition; tighter supply is the exit condition. Investors who position now are buying at the soft point of the cycle.

The VIA Rapid Green Line breaks ground in 2025 and begins service in early 2028 along a 10.35-mile north-south BRT corridor on San Pedro Avenue from the airport through downtown to Steves Avenue. Properties within a half-mile of Green Line stations are the most specific forward opportunity for transit-premium pricing. A second Silver Line running east-west from Frost Bank Center toward Our Lady of the Lake University is projected for late 2030, extending the transit-oriented corridor.

The $2.5 billion San Antonio International Airport expansion adds nonstop international capacity and directly supports demand near the northern terminus of the Green Line. If Toyota awards the $2 billion assembly line to San Antonio, it would be a population and employment event that the current price deck does not reflect.

The ADU code evolution is still in progress; final UDC adoption expected in late 2025 will determine how broadly citywide ADU rights expand. Operators who are already familiar with the permitting process will move faster than those who are not.
