San Antonio's cost seg story is about a specific demand driver almost no other market has: the military PCS (Permanent Change of Station) cycle, which creates constant 30-to-180-day housing demand from incoming and outgoing personnel, contractors on DoD contracts, and traveling medical/nursing staff at major hospitals. Furnished properties serving this market reclassify at STR-level percentages (25–30%+) because the full FF&E package qualifies as 5-year property — but the operational model is closer to LTR (stable multi-month tenants, low turnover, reduced management burden). Texas zero state income tax + federal-only math + non-passive MTR classification (when structured correctly) makes this one of the cleanest tax-shelter setups available.
Joint Base San Antonio: The Demand Driver No One Talks About
Joint Base San Antonio (JBSA) consolidates three formerly-separate installations into a single command:
- Randolph AFB (northeast suburbs, near Universal City): pilot training, Air Force Personnel Center. Approximately 11,000 personnel.
- Fort Sam Houston (central, near Alamo Heights): Army medical training, Brooke Army Medical Center (BAMC). Approximately 32,000 personnel.
- Lackland AFB (southwest, near Kelly Field): basic military training, cybersecurity. Approximately 37,000 personnel.
Add in civilian contractors, DoD program staff, and Air Force / Army reservists, and total JBSA footprint approaches 80,000+ personnel across Bexar County. That's larger than the population of most mid-sized US cities — and it's embedded within San Antonio's rental demand.
The rental demand pattern from this population has specific characteristics:
- Constant turnover: PCS orders rotate personnel on 2-to-4-year cycles. At any given time, ~25% of JBSA personnel are in some phase of PCS-related housing transition.
- Furnished preference: Incoming personnel often arrive before household goods ship; outgoing personnel ship furniture in advance. Both create demand for furnished short-to-medium-term housing.
- Per-diem / BAH-supported rates: DoD reimburses housing at Basic Allowance for Housing (BAH) rates + per diem for personnel in transit. For San Antonio, BAH rates (2025): $1,500–$2,400 depending on rank and dependent status. Furnished properties commanding $3,200–$4,800/mo fit within this reimbursement structure.
- Seasonal concentration: Summer PCS season (May–August) creates 2–3× normal rental demand. Properties that list MTR in May-August can often secure 4+ month contracts at peak rates.
Why MTR Reclassifies Like STR (But Operates Like LTR)
The IRS test for short-term-rental non-passive treatment under Treas. Reg. §1.469-1T is the 7-day average stay. Medium-term rentals (30+ day minimum stays typical) DON'T meet that test — average stays exceed 7 days by definition.
But the reclassification math is still favorable because MTR properties are furnished. All the 5-year personal property that drives STR reclassification (furniture, appliances, kitchenware, linens, electronics, specialty lighting) is still present in an MTR setup. The 5-year bucket reaches 15–22% of basis — comparable to an STR — because the furnishings are there regardless of the rental-period classification.
The passive-activity question is separate:
- MTR with 30-90 day stays = standard rental activity under §469. Passive by default unless REPS-qualified.
- MTR with significant services provided (daily cleaning, concierge) = could be argued as Schedule C trade or business. Rare; most MTRs don't provide hotel-level services.
- MTR that tracks average stay and keeps it below 7 days (mixing 2-4 night stays with 30+ day stays) = may qualify as STR-rules non-passive, but careful documentation required.
For most San Antonio MTR investors, the realistic scenario is: passive rental activity unless REPS-qualified (typically via a non-working spouse managing 4+ properties). The reclassification dollars are the same as an STR; the usability of the Year-1 loss depends on the passive-activity qualification.
Example 1: Stone Oak Furnished MTR
Stone Oak SFR — Furnished MTR Targeting BAMC Staff
A 1,850 sqft SFR in the Stone Oak neighborhood — walking distance to Fort Sam Houston's Brooke Army Medical Center. Owner purchased with the specific intent of serving traveling medical professionals (nurses, doctors, military medical staff) on 2-to-6 month assignments. Furnished to hotel-grade: full kitchen, designer bedrooms, work-from-home setup, commercial-grade WiFi. Currently commands $3,650/mo fully furnished + utilities.
| Component | MACRS Class | Amount |
|---|---|---|
| Full furnishings (beds, living room, dining, office) | 5-yr | $32,000 |
| Kitchen: appliances, cookware, dishware, utensils, linens | 5-yr | $14,500 |
| Electronics (TVs, smart home, Wi-Fi mesh, smart locks) | 5-yr | $8,500 |
| Work-from-home setups (2 dedicated offices with monitors, desks) | 5-yr | $6,500 |
| Specialty lighting, decor, mirrors, art package | 5-yr | $7,000 |
| Appliance package (W/D, dishwasher, range, refrigerator) | 5-yr | $5,500 |
| Interior finishes (cabinets, counters — 2024 owner's update) | 5-yr | $12,000 |
| Backyard: patio, fire pit, string lights | 15-yr | $6,500 |
| Driveway, fencing, landscaping | 15-yr | $9,000 |
| Total reclassified (26.0% of $350K basis) | $91,500 |
26% reclassification on a fully-furnished MTR is comparable to most STR markets — and this is a $385K property where a comparable unfurnished SFR might reclassify at 17–20% (basic appliances + site improvements only). The furnished package drives nearly a 6 percentage-point improvement in reclassification rate. Texas zero state tax means the $33,855 is pure federal; no state conformity considerations.
Passive-activity note: Average 75-day stay = standard rental activity, passive by default. This owner isn't REPS-qualified (full-time W-2 professional), so the Year-1 loss gets suspended. Value releases at sale or against future passive income.
Example 2: Alamo Heights Luxury MTR Portfolio
Alamo Heights 3-Property Portfolio — REPS-Qualified Owner
A San Antonio investor couple built a 3-property MTR portfolio in Alamo Heights specifically targeting traveling medical staff rotating through BAMC and San Antonio's hospital network. The non-working spouse manages all three properties full-time (far exceeding 750 hours on real estate activities + real estate representing 100% of her personal services). Cost seg applied to the most recent 2024 acquisition:
| Component (Property 3 only) | MACRS Class | Amount |
|---|---|---|
| Luxury furnishings (4BR package, high-end rental spec) | 5-yr | $48,000 |
| Kitchen: appliances, custom built-ins, full kitchenware | 5-yr | $22,000 |
| Electronics, smart home, 2 dedicated work-from-home offices | 5-yr | $15,500 |
| Bath fixtures, specialty tile (2024 owner's renovation) | 5-yr | $18,000 |
| Interior finishes (cabinets, counters, flooring) | 5-yr | $28,000 |
| Specialty lighting, decor, designer art package | 5-yr | $12,000 |
| Appliance package (W/D, additional kitchen items) | 5-yr | $6,500 |
| Backyard: patio, pool shell with equipment split | 15-yr + 5-yr | $28,000 |
| Driveway, landscaping, fence, exterior lighting | 15-yr | $12,500 |
| Total reclassified (29.0% of $450K basis) | $190,500 |
REPS qualification makes the $70K Year-1 savings immediately usable against the household's W-2 income. Across the 3-property portfolio, combined Year-1 cost seg savings approach $180K–$220K — dropping effective household tax rate by ~15 percentage points on a roughly $500K W-2 income. Texas zero state tax means no state-level conformity complications, and the combined portfolio is large enough to comfortably meet both REPS tests without ambiguity.
The Texas Tax Math: As Clean As It Gets
Texas has no state income tax. That makes cost seg math in San Antonio among the cleanest in the country:
- Every dollar of federal Year-1 tax savings drops straight to the investor
- No state-level bonus depreciation conformity research required
- No state-level AMT interactions
- Zero state-level depreciation recapture at sale
For a 37% federal bracket investor, combined effective rate = 37%. Simple. Compared to neighboring states (Oklahoma 4.75%, New Mexico 4.9%, Arkansas 4.7%), Texas investors keep 4–5 percentage points more of every dollar of Year-1 cost seg savings.
The sell-within-5-years math also works cleanly in Texas. Federal Sec. 1250 depreciation recapture at 25% applies at sale (everywhere), but there's zero state recapture. This makes San Antonio — like Las Vegas and Florida — a market where shorter-hold cost seg strategies don't get eroded by state-level recapture.
Why San Antonio Beats Austin for Military MTR
Austin gets the headlines for Texas rental investing, but San Antonio is quietly a better market for specific strategies. Comparison on military-MTR-relevant factors:
- Entry pricing: San Antonio $275K–$475K target properties vs. Austin $500K–$900K — 40–45% lower entry
- Military demand: San Antonio has JBSA (80,000 personnel); Austin has no major military installation
- Medical MTR demand: San Antonio has BAMC + University Health + Methodist; Austin has Dell Seton but smaller scale
- STR regulatory: San Antonio has STR-permitted zones but is tightening; Austin is even more restrictive
- Property tax burden: Texas high property tax applies to both (~2.2–2.5%), but San Antonio's lower purchase prices mean lower absolute tax bills
- Appreciation potential: Austin has had higher historical appreciation but also more volatility; San Antonio's growth is slower but steadier
For investors optimizing specifically for MTR cash flow + cost seg tax shelter (rather than pure appreciation), San Antonio is a cleaner mathematical bet. Austin attracts Bay Area-style appreciation bets; San Antonio attracts yield-focused investors who want the tax shelter without the pricing risk.
The Alamo Heights / Stone Oak / Universal City Triangle
The highest-value MTR markets in San Antonio cluster in three specific submarkets, each serving a different piece of the JBSA + medical demand:
- Alamo Heights / Terrell Hills: Premium MTR targeting BAMC staff, senior military officers, hospital executives. $400K–$650K purchase range. Higher rents ($3,800–$5,500/mo furnished). Walkable to restaurants and amenities.
- Stone Oak / Thousand Oaks: Family-friendly MTR targeting relocating military families and dual-income hospital couples. $325K–$475K. Good schools. 15–20 min drive to BAMC.
- Universal City / Schertz / Selma: Randolph AFB proximity. Lower entry ($275K–$400K). Target demographic: Air Force pilot training personnel, young families.
All three submarkets benefit equally from the zero-state-tax + MTR-furnished-reclassification combination. The submarket choice is more about targeting which demographic and matching price-to-rent expectations.
A note on VRBO/Airbnb vs. dedicated MTR platforms: Traditional STR platforms (Airbnb, VRBO) discourage listings with 30+ day minimums. The MTR community has moved to dedicated platforms: Furnished Finder (travel-nurse-dominant), Blueground, Landing, Sabbatical, and corporate-housing brokers. San Antonio investors running MTR models typically list on Furnished Finder first (where they reach the BAMC travel-nurse market directly) and supplement with corporate-housing-broker relationships for direct-to-relocating-personnel placements.
When San Antonio Cost Seg Doesn't Work
- Property outside the MTR-demand zone. San Antonio has significant inventory (East Side, South Side, far-out suburbs) that doesn't capture MTR demand. A property there defaults to standard LTR — still works for cost seg but at lower reclassification (furnishings absent) and lower rent.
- Unfurnished LTR with passive-activity non-REPS owner. Same situation as most LTR markets — cost seg produces passive losses that wait for sale or REPS qualification. Value exists but not immediate W-2 offset.
- Property under $225K. Cost seg math tightens on low-basis properties. Below $225K purchase, the study fee starts to eat a non-trivial share of Year-1 savings.

Frequently Asked Questions
How much does a cost segregation study cost in San Antonio?
Cost Seg Smart studies start at $495 for properties under $300K and $795 for properties up to $1M — the same price nationwide. There are no travel fees or site visit charges because the IRS does not require a physical inspection. Traditional firms in the San Antonio market typically charge $3,000 to $10,000 for the same analysis.
What's the typical accelerated depreciation for a San Antonio rental property?
San Antonio investment properties typically reclassify 20-35% of depreciable basis into 5-year and 15-year MACRS categories through cost segregation. For a $325,000 rental property, that translates to roughly $24,000 in Year 1 tax savings at the 37% bracket. Short-term rentals tend toward the higher end of this range due to furniture, fixtures, and equipment.
Does Texas conform to federal bonus depreciation rules?
Texas has no state income tax, so cost segregation savings are entirely at the federal level. This simplifies the analysis — there are no state-level depreciation adjustments to track.
How fast can I get a cost segregation study for my San Antonio property?
Under one hour from order to delivery. Cost Seg Smart reports are generated using the same RSMeans construction cost data and IRS classification methodology as traditional firms — but delivered in minutes instead of weeks.
