Self-Managing a San Antonio Rental: When It Pays Off and When to Hire a PM

Self-management works in San Antonio when you own one to three properties inside a 30-minute drive, you answer your phone, and you can keep a vendor list, a lease, and a ledger organized without it eating your evenings. It stops working the moment any of those break — or the moment a bad tenant forces you into JP court while you're trying to run a day job.

The math most first-time landlords run is wrong because they compare a PM's 8–10% monthly fee to zero. The real comparison is PM cost versus your vacancy days, your turnover quality, your legal exposure under Texas Property Code Chapter 92, and the dollar value of your own time. Below is how to decide, what systems you need if you self-manage, and the triggers that should push you to hire out.

The real cost of a San Antonio PM

Typical Bexar County residential PM pricing, as of recent cycles, runs roughly:

• Monthly management: 8%–10% of collected rent (sometimes flat $99–$150 on cheaper units)
• Leasing fee: 50%–100% of one month's rent on a new tenant placement
• Renewal fee: $200–$400 or ~25% of one month's rent
• Setup / onboarding: $0–$300
• Maintenance markup: some PMs add 10% on top of vendor invoices; others don't — read the agreement

On a $1,800/month rental in Converse with a new tenant placed annually, you're looking at roughly $2,160 in management fees plus $900–$1,800 in leasing fees — call it $3,000–$4,000 a year, before maintenance markup. That's the number to beat with your own time and systems.

When self-managing actually makes sense

Self-management is the right call when most of these are true:

• You own 1–3 doors and they're inside Loop 1604, or at least inside Bexar County. A property in Boerne or Cibolo is fine; a rental in New Braunfels while you live in Stone Oak is not.
• You can physically be at the property within an hour for a real emergency (burst SAWS line, HVAC out in July, lockout).
• You can answer a tenant call or text within a few hours during business hours — not three days later.
• You have, or are willing to build, a vendor bench: a licensed HVAC tech, a plumber, a roofer, a general handyman, and an electrician you've used more than once.
• You're comfortable reading a lease, serving a notice to vacate under § 24.005, and walking into a JP court if it comes to that.
• You screen with actual criteria — credit, income at 3x rent, rental history, criminal with individualized assessment per HUD guidance — and you apply them consistently to every applicant.

If all of that is true, self-managing one to three SA rentals is a reasonable side operation. The fee savings are real and the control is meaningful.

When to hire a PM, even if the math looks close

Hire out when any of these apply:

• You live out of state or far out of market. Austin is too far. Dallas is too far. A Randolph-based officer who PCSs to Ramstein is too far.
• Your portfolio crosses 4+ doors and you're not treating it as a business with its own books.
• You can't tolerate a 2 a.m. call. Tenants can and will call at 2 a.m. when the water heater fails on Christmas Eve. A PM has on-call rotation; you don't.
• You've never done an eviction and you're in a submarket where turnover and non-payment risk are higher — parts of the East Side, some pockets of the South Side, large multi-tenant conversions.
• You own a short-term or mid-term rental near the Pearl, Southtown, or the Medical Center. Those are operationally different animals — cleaning turns, dynamic pricing, city STR permitting — and specialist management earns its fee.
• You have a W-2 job that penalizes distraction. Surgeons, active-duty, pilots, attorneys in trial — your hour is worth more than the PM fee.

The systems you need if you self-manage

Lease and disclosures

Use the Texas REALTORS Residential Lease (TXR-2001) if you have SABOR/TAR access through an agent, or a Texas-specific lease reviewed by a landlord-tenant attorney. Do not use a generic online lease — it will miss Chapter 92 provisions you're required to include. Separately, deliver:

• Lead-based paint disclosure on any pre-1978 property (a lot of 78201, 78209, 78210, 78212 inventory)
• Written notice of the name and address of the owner/manager under § 92.201
• Smoke alarm and re-key acknowledgments (§ 92.153, § 92.156)

Rent collection

Pick one rail and enforce it. Baselane, Avail, RentRedi, or Zelle with a dedicated LLC account all work. Cash and personal Venmo do not. Your lease should state the due date, the grace period (Texas now requires a minimum two full days before a late fee under § 92.019), and the exact late fee structure. Enforce it on day one; selective enforcement is how you lose leverage later.

Maintenance intake

One channel, in writing. A dedicated email or a portal ticket — not a mix of texts, calls, and Facebook messages. Texas Property Code § 92.052 obligates you to repair conditions that materially affect health and safety after written notice; you want that written notice timestamped and in one place. Target response times:

• Emergency (no water, no A/C over 85°F, gas leak, sewage, active leak): same day
• Urgent (appliance down, one non-working outlet, partial HVAC): 48–72 hours
• Routine (cosmetic, slow drain): 7–10 days

Vendor bench

Three names per trade. One primary, one backup, one emergency. Pay invoices within a week — good SA vendors have more work than they can handle and they remember who pays fast. Ask for a W-9 up front so 1099s at year-end aren't a fire drill.

What most people get wrong

• Treating the security deposit casually. Under § 92.103–104 you have 30 days after the tenant surrenders the property and provides a forwarding address to return the deposit or give an itemized list of deductions. Miss it and you're exposed to $100 + 3x the wrongfully withheld amount + attorney's fees. Set a calendar reminder the day you get keys back.
• Self-help eviction. Changing locks, shutting off CPS Energy or SAWS, or removing doors to force a tenant out violates § 92.0081 and § 92.331. Even if they haven't paid in 90 days, you go through the JP court: 3-day notice to vacate, then petition in the correct Bexar County JP precinct (there are four; venue is based on property location), hearing typically 10–21 days out, then writ of possession executed by a constable.
• Skipping written notice on repairs. Verbal complaints don't trigger the landlord's statutory repair duty cleanly. Require written notice in the lease, and when a tenant calls, reply by email summarizing what they reported. That protects both sides.
• Under-screening to fill a vacancy fast. A vacant month on an $1,800 unit costs $1,800. A bad tenant costs $5,000–$15,000 plus months of your life. Hold your criteria.
• No mid-lease inspection. Do a documented interior check at month 6 with 24-hour written notice. You catch unauthorized pets, water damage, and maintenance the tenant never reported. Photos go in a dated folder.
• Confusing NEISD and NISD when marketing. If you list a Stone Oak rental as "Northside ISD" when it's actually NEISD, families will walk at the showing and you'll eat another vacancy week. Verify school zoning on the district's attendance boundary locator before you publish.
• Under-insuring. A standard DP-3 landlord policy plus a $1M umbrella is cheap compared to a slip-and-fall suit. Require tenants to carry renters insurance with you listed as an additional interested party.

The hybrid option

A lot of SA landlords land here: self-manage day-to-day, but pay a broker a tenant-placement-only fee (typically 50–75% of one month's rent) to run the listing on the SABOR MLS, handle showings, screen applicants, and prepare the lease. You keep the 8–10% monthly fee and offload the part that eats the most time — marketing and screening. For a landlord with a demanding W-2 and one or two doors, this is often the right shape.

When to switch

Re-evaluate annually. Triggers that should push you from self-managed to professionally managed:

• A second unplanned eviction filing
• A PCS or job relocation out of market
• Growing past 4 doors without building a real back office
• A fair-housing complaint, even one you win — the next one is more expensive
• Any serious injury claim on the property
