Turning Your San Antonio Home Into a Rental: The Setup Nobody Warns You About

Most first-time landlords in San Antonio don't fail at screening tenants or drafting a lease. They fail at the six weeks before the tenant moves in — the switch from owner-occupant to landlord — because nothing about that transition is automatic. Your homestead exemption doesn't unfile itself. Your homeowner's policy doesn't convert. Your lender doesn't notice unless something goes wrong, and then they notice hard.

If you're keeping a Bexar County home and renting it out — because you PCS'd, upgraded, inherited it, or bought the next house — here is the setup work to do before you list.

Decide the homestead question before you list

Texas Property Tax Code § 11.13 lets you claim a homestead exemption on your principal residence, filed with BCAD on Form 50-114. It reduces taxable value and caps annual appraisal increases at 10%. It only applies to a home you occupy as your principal residence on January 1 of the tax year.

The moment the home stops being your principal residence, you are supposed to notify BCAD and remove the exemption. Two practical points:

• If you moved out mid-year, the exemption generally stays on for the current tax year but must come off going forward. Leaving it in place while renting is exemption fraud, and BCAD does catch it — often via a rental listing pulled during audit.
• Once the exemption is gone, you lose the 10% cap. Expect taxable value to jump toward market on the next reassessment. Build that into your pro forma before you set rent, not after your first tax bill lands.

If this is genuinely short-term (a one-year PCS with a firm return date), talk to a Texas property tax consultant about the timing. For long-term conversions, plan on paying the un-exempted bill starting the year after you convert.

Switch your insurance from HO-3 to DP-3

A standard homeowner's policy (HO-3) requires you to occupy the home. Rent without switching and a claim — fire, hail, tenant injury — can be denied. What you want is a landlord policy, typically a DP-3 (dwelling fire, special form), with:

• Replacement cost on the structure, not actual cash value
• Loss-of-rent coverage, usually 12 months, so a fire doesn't wipe out cash flow while the house is being rebuilt
• Landlord liability of at least $300K, often $500K, plus an umbrella if you own other assets
• A lease clause requiring the tenant to carry renter's insurance and name you as an additional interested party

San Antonio is a hail market. Roof deductibles on DP-3 policies in Bexar County are commonly 1–2% of dwelling value, sometimes higher — read that page of the policy before binding. If the home sits near Salado Creek, Leon Creek, Olmos Basin, or any of the near-Southside floodplains, pull the FEMA map and price a separate NFIP policy. Standard DP-3s do not cover flood.

Read your mortgage's occupancy clause

Most owner-occupied loans — conventional, FHA, VA — require you to occupy the home as your primary residence for 12 months after closing. Renting inside that window is technically occupancy fraud, and lenders can call the note due. After the 12 months, most loans permit conversion with no notice, but check your specific note.

For VA loans in particular — relevant for JBSA-Randolph, Lackland, and Fort Sam Houston buyers — a PCS order is generally accepted as a legitimate reason to convert earlier than 12 months. Keep a copy of the orders in your file.

Check the HOA before you market the unit

A large share of San Antonio's newer subdivisions have HOAs, especially north of Loop 1604 (Stone Oak, Alamo Ranch, Cibolo Canyons) and out through Schertz, Cibolo, and Boerne. Increasingly common restrictions:

• Minimum lease terms of 6 or 12 months, effectively banning short-term rentals
• Rental caps limiting the percentage of homes leased at any time, sometimes with a waitlist
• Tenant registration requirements and a fee
• Restrictions on yard signs

Pull the current CC&Rs and rules from the management company, not the packet you got at closing three years ago. Rules change by amendment vote and old copies go stale.

Handle the utility handoff cleanly

Two utilities, two providers, and people mix them up constantly:

• CPS Energy — electric and natural gas. Owned by the City of San Antonio.
• SAWS — water, wastewater, and stormwater. Separate utility entirely.

For rentals, put both accounts in the tenant's name effective the lease start date. Do not leave utilities in your name and bill the tenant back — you become responsible for their unpaid balance, and unpaid SAWS charges can attach to the property. Confirm service has been activated in the tenant's name before releasing keys.

If the property is in New Braunfels, Boerne, Schertz, Cibolo, or a co-op territory, the providers change (New Braunfels Utilities, GVEC, Bandera Electric Cooperative). Tell the tenant which utility to call — don't assume they know.

Set rent against real, current comps

Overpricing a San Antonio rental right now costs you weeks of vacancy that never come back. RentInSA's active listings as of September 2026 show 4,698 available rentals across the metro with a median asking rent of $1,700/mo and a median of $1.11 per square foot. Bedroom-level medians:

• 1BR: $950/mo
• 2BR: $1,300/mo
• 3BR: $1,695/mo
• 4BR: $2,100/mo

Submarket matters more than the metro number. Schertz medians run around $1,995 and Cibolo around $2,100, while the City of San Antonio proper sits at $1,695. Boerne runs materially higher at $2,925 — different buyer, different housing stock. Pull five to ten active listings within a one-mile radius of your property with similar beds, baths, square footage, and finish level, and price at or slightly below the median of that set. Listings added in the last 30 days (there were 2,887 metro-wide) are your best comps because they reflect what tenants are actually seeing today.

What most people get wrong

• Leaving the homestead exemption on after moving out. BCAD flags it, back-assesses, and adds penalties. File the removal when you convert; don't wait for a notice.
• Keeping the HO-3 because it hasn't lapsed. A denied claim after a kitchen fire costs more than the DP-3 premium for the next decade. Switch before move-in, not after.
• Skipping the HOA rental-cap check. Some north-side and Schertz HOAs will fine you and refuse to acknowledge your lease. Confirm eligibility in writing before marketing the unit.
• Pricing off a national estimator. Those tools smooth across large ZIPs and miss the two-block school-boundary effects that drive real San Antonio pricing. The line between NEISD and NISD, or crossing into Alamo Heights ISD (78209), can move rent by hundreds of dollars.
• Skipping a dated, photo-documented move-in condition report. You'll need it in a Bexar County JP court if the security deposit is disputed under Texas Property Code § 92.103–104. Do it the same day the tenant takes possession, with the tenant signing off.
• Forgetting the military clause. Active-duty tenants are common here. SCRA § 3955 lets a servicemember terminate on PCS or deployment orders with 30 days' notice after the next rent date. Charging an early-termination fee against orders isn't enforceable and it burns your reputation in a tight referral market.

Before you take the first showing

Have the DP-3 bound, the HOA cleared, the homestead removal queued, comps pulled, and a written condition-report template ready. That is the setup. Everything after — screening, lease, move-in walk — assumes you did this part first.
