Rental Arbitrage in San Antonio, TX: Rules, Rents and Landlords

Is rental arbitrage legal in San Antonio?

Yes, with a permit for nightly stays and the owner's written authorization. Ordinance 2018-11-01-0858, amended by Ordinance 2024-06-13-0433, defines a short-term rental as a house, apartment, condo or accessory dwelling rented for less than 30 consecutive days (and at least 12 hours). Each unit needs its own permit, valid three years, non-transferable, with the permit number on every listing. Type 1 covers the owner's or operator's primary residence and has no cap. Type 2 covers everything else, including an arbitrage unit.

The city's application is plain: if the applicant is not the owner, "a notarized authorization from the owner is needed." Type 2 permits are capped at 12.5% of dwelling units per block face or multifamily building, rounded down, with at least one per block face or property. Past that, you need a Board of Adjustment special exception ($690 for non-homestead applicants, plus 8%), and the city's own report shows 25% of 87 cases approved. The unit also needs an off-street parking space, a 24/7 operator, and zoning other than C-3, L, I-1 or I-2. Permits are city-limits only: Alamo Heights, Leon Valley, Hollywood Park and the other enclave cities set their own rules.

Enforcement is real. In FY2025 the city had 3,339 active permits (77% Type 2), ran 1,820 investigations, found 582 violations and revoked 516 permits. Since the 2024 amendment, platforms must remove listings without a valid permit number, and three citations in three years costs the permit. Stays of 30 or more consecutive days fall outside the definition: no permit, no hotel tax, and no 31-day quirk.

What does a San Antonio 2-bedroom cost, and what does it rent for furnished?

Low, and still falling. Zumper's October 2026 median for a two-bedroom apartment is $1,204, with two-bedrooms of all types down 6% in a year; Apartment List's October figure is $1,173, down 3.5%.

Furnished 30+ night rates are listing asks with no index behind them, so treat them as a ceiling. Corporate housing listings for two-bedrooms run $1,504 on the far west side, $2,029 in 78238 and $2,542 in 78248, and a 2026 travel-nurse guide quotes $2,600–3,600 for a furnished 2BR. Furnished Finder's 206 live two-bedroom asks across central San Antonio put the middle half at $1,800–2,610 (median $2,100), so plan on $1,800 to $2,600 for a clean two-bedroom; on the far west and south sides, assume the low end. The Medical Center has the deepest travel-nurse demand but not the top rates: listings with Medical Center in the title have a $1,950 median, and none ask more than $2,500. The top-performing units ask about $2,800 and up (the top 10% of independent hosts, a $2,838 median for Landing-managed Class-A units, $2,800–3,805 at Republic at Alamo Heights), sit in Alamo Heights, King William, Southtown and Pearl, and nearly all include utilities (worth about $250 a month), in-unit laundry (98% of top-quartile listings vs 82% of the rest), parking, two or more baths, pets and a 30-night minimum; these are asks, not booked rents.

Nightly numbers are weak for Airbnb arbitrage. One vendor estimate (AirROI, October 2025 to September 2026) shows 41% occupancy at a $204 average daily rate across 5,399 listings, and a median two-bedroom grossing about $13,400 a year. That is less than a year of rent at the median, before the hotel tax and the permit.

Does the math work in San Antonio?

Yes at the median, and comfortably with a concession or a top-of-range rate. We ran four two-bedroom scenarios through our Deal Analyzer with its default assumptions: 85% occupancy, 90-night stays, $150 per turnover, 3% platform fees, $365 a month for utilities, insurance and supplies, $5,000 per bedroom to furnish, a deposit equal to one month's rent, and $800 to source the unit.

At the $1,204 median rent and a $2,300 furnished rate, the unit nets about $280 a month at a 72% break-even occupancy, with a 49-month payback: workable but slow. Take the rent down to $1,070 (a free month spread over a year plus a small negotiated discount) and it nets about $410 at 66% break-even. Hold the median rent but get $2,600, the top of the typical range, and it's about $525 a month, 64% break-even, 26-month payback. At the $2,800 top-performing rate it nets about $690 a month at 59% break-even with a 20-month payback, well past the twice-rent test. Getting that rate takes an Alamo Heights, King William, Southtown or Pearl location, utilities included, in-unit laundry, parking and a second bath, not a Medical Center address. The quick test is that the furnished rate should be about twice the rent. In San Antonio that means roughly $2,400 against a $1,204 lease, inside the typical furnished range rather than at the top of it.

Who books 30+ night stays in San Antonio?

Clinicians and the military. The South Texas Medical Center on the northwest side has 14 hospitals and about 87,000 employees, including University, Methodist, Methodist Children's and CHRISTUS. Travel nurses on 13-week contracts are the core furnished tenant.

Joint Base San Antonio (Lackland, Fort Sam Houston and Randolph) had 74,713 direct employees in 2025 and an average daily student load of 23,867. Lackland's basic training alone has more than 9,000 students and graduates more than 79,000 a year, which brings instructors on temporary duty, families between postings and graduation-week visitors. Brooke Army Medical Center at Fort Sam adds about 8,500 staff plus contract clinicians and patient families. The Stock Show & Rodeo (February 11–28, 2027, about 1.5 million visitors) is a nightly peak, and after floods like June 2025's, insurer-paid displacement housing follows.

Where will San Antonio landlords say yes?

Almost anywhere new, because San Antonio has the softest big apartment market in the country. RealPage put occupancy at 92.5% in September 2025, the lowest of the 50 largest markets. CoStar's vacancy hit 16% at the start of 2026 and was 14.9% in Q3 (6.9% in 2022), Northmarq counted 1,700 units of negative absorption in Q1 2026, and Apartment List found 56.8% of properties offering at least a free month in September 2026.

The pressure is easing, which is the reason to move now. Deliveries fall from 13,000–14,000 units in 2024 to about 5,000 in 2026 and 2,000 in 2027, and CoStar expects concessions to end and rents to rise from late 2027. The remaining pipeline is concentrated in South Central (about 900 units) and Far West (about 620), with a run of bond-assisted lease-ups downtown. Those are the buildings our finding-properties guide tells you to call first. If you plan any nightly stays, ask the leasing office how many Type 2 permits the property already holds.

Which San Antonio neighborhoods should you target?

Start near the hospitals and the bases, where the tenants already are. Rents are Zumper neighborhood averages unless noted.

What goes wrong in San Antonio?

The density lottery. A 100-unit complex gets at most 12 Type 2 permits, first come, and only about a quarter of special exceptions are approved. The $1,080 is paid up front for three years and the permit can't be transferred. Stays of 30+ nights avoid the cap.

Hotel tax paperwork. Airbnb and Vrbo have remitted the city's 9% for operators since March 10, 2025, but you still file a monthly city report through Neumo (hoteltaxonline.com), even at $0, and remit the county share yourself. The county rate itself differs between city pages: the Development Services STR page says 1.75% and the Finance hotel-tax page says 2%, so confirm it before you price. Tax delinquency is the leading reason permits are revoked.

Covenants and the lease. The city does not enforce HOA rules or deed restrictions, but it expects you to check them. Tarr v. Timberwood Park (2018), a San Antonio case, held that a bare "residential purposes" or "single family" covenant doesn't bar short-term rentals; an explicit restriction still does. Under Property Code §91.005, an unconsented sublet lets the landlord terminate and evict both you and your guest.

Flooding and the rent reset. Creek-adjacent units carry flood, outage and insurance risk: the June 2025 flash flood dropped 3 to 8 inches of rain and killed more than 10 people. And when concessions end from late 2027, a one-year lease renews higher; price the deal at the full rent, not the effective one.
