Flat Fee Realtor in San Antonio, TX
KAT Realty Group is a full-service flat fee real estate service serving San Antonio and the surrounding Bexar County area. Buyer representation is a flat $4,999, paid at closing. Listing a home is a flat $5,999 — $600 at signing, the balance at closing and only if the sale actually closes. The service is the same one a traditional agent provides; the pricing is not a percentage of what your home is worth.
Why San Antonio Buyers and Sellers Are Exploring Flat Fee Representation
San Antonio is the most balanced of Texas's four big metros right now. The median sale price sits around $295,000, up roughly 4.5% year over year by the Texas Real Estate Research Center's count, with 3.2 to 3.4 months of inventory and homes taking 42 to 45 days to sell. That is neither a seller's market nor a buyer's market — it is a market where both sides have time to think.
It is also a market where the commission math is unusually visible. At a $295,000 sale price, a 3% listing commission is $8,850 and a 3% buyer-side commission is another $8,850. Those are large numbers against a median that is roughly $150,000 below Austin's. The percentage does not care what the house costs; the work does not change much either.
Potential Savings With a Flat Fee Realtor in San Antonio
The table below compares a 3% commission on one side of the transaction against KAT Realty Group's flat fee. Buyer-side figures assume the seller or builder offers 3% cooperating compensation; where that offer exceeds the flat fee, the difference may be applied toward your allowable closing costs, subject to lender approval.
| Home Price | Traditional 3% Commission | KAT Realty Flat Fee | Potential Difference |
|---|---|---|---|
| $250,000 | $7,500 | $4,999 buyer / $5,999 seller | $2,501 / $1,501 |
| $295,000 (metro median) | $8,850 | $4,999 buyer / $5,999 seller | $3,851 / $2,851 |
| $350,000 | $10,500 | $4,999 buyer / $5,999 seller | $5,501 / $4,501 |
| $450,000 | $13,500 | $4,999 buyer / $5,999 seller | $8,501 / $7,501 |
| $600,000 | $18,000 | $4,999 buyer / $5,999 seller | $13,001 / $12,001 |
Commission rates are negotiable and vary by agent; 3% is used here as a common reference point, not a fixed standard. Buyer-side benefit depends on the compensation actually offered and on lender rules.
Where this is honest about itself: below roughly $200,000, a 3% commission and a flat fee land close together, and the advantage narrows to very little. That matters in San Antonio more than in Austin or Plano, because real parts of Bexar County — the far South Side, much of South San Antonio ISD, pockets east of I-37 — still trade below that line. If your home is in that range, ask us to run your specific numbers before assuming a flat fee saves you money. Sometimes it barely does.
Flat Fee Buyer Representation in San Antonio
Buyer representation is a flat $4,999 anywhere in Texas, due at closing. That covers the full scope: property search and showings, comparable-sale analysis before you write an offer, offer strategy and negotiation, option-period and inspection guidance, repair-credit negotiation, and coordination with your lender and title company through to closing.
There is no per-offer charge and no cap on the number of offers written. In a balanced market that matters — San Antonio buyers frequently write on two or three homes before one sticks, and a fee structure that penalizes that is a fee structure working against you.
Homes above $900,000 carry an additional amount for the added errors-and-omissions coverage: $1,000 from $900,000 to $2 million, $2,000 from $2 million to $3 million, and $5,000 above $3 million.
San Antonio New Construction Buyer Agent Services
New construction is a large share of the San Antonio market, concentrated on the far North and West sides — Alamo Ranch, Potranco, the 1604 corridor, Converse, Cibolo and Schertz, and out toward Boerne and New Braunfels.
Two things are worth knowing before you tour a model home. First, the builder has already budgeted a buyer-side commission into the price; arriving without an agent does not lower the price, it just leaves that money with the builder. Second, nearly every builder requires your agent to be disclosed on your first visit, before you sign the guest register — and most will not pay an agent disclosed later, permanently, for that community.
Texas Property Code §5.008(e)(10) also exempts a never-occupied new residence from the seller's disclosure requirement, so on a new build you receive no written answers about flood history, floodplain location or prior water intrusion. In the Hill Country drainage north and west of the city, that is not a theoretical gap.

Flat Fee Listing Services in San Antonio
Listing a San Antonio home is a flat $5,999 — $600 at signing, the balance at closing and only if the home sells. If it does not sell, you do not owe the balance.
That includes a comparative market analysis and pricing strategy, professional photography coordination, the SABOR MLS listing and syndication to the major portals, showing coordination, offer review and negotiation, and transaction management from contract to close. It is the traditional listing scope at a fixed price, not a self-managed MLS entry with support bolted on.
San Antonio Neighborhoods and Areas Served
San Antonio's price spread by area is wide enough that a metro median tells you very little about your own block. Recent area medians:
| Area | Recent median | 3% commission at that price |
|---|---|---|
| Alamo Heights | $445,000 | $13,350 |
| The Pearl / Mahncke Park | $385,000 | $11,550 |
| Boerne | $375,000 | $11,250 |
| North Star / Quarry | $355,000 | $10,650 |
| Downtown / Southtown | $325,000 | $9,750 |
| Stone Oak / North Central | $315,000 | $9,450 |
| New Braunfels | $280,000 | $8,400 |
Area medians move month to month and differ between sources. Use them as orientation, not valuation.
We also serve Terrell Hills, Olmos Park, King William, Monte Vista, Helotes, Leon Valley, Live Oak, Selma, Universal City, Converse, Cibolo, Schertz and Fair Oaks Ranch.
What San Antonio Property Taxes Actually Cost
Bexar County's combined tax rate is high even by Texas standards, and the school district line drives most of it. A typical San Antonio homeowner inside North East ISD pays roughly $2.27 per $100 of assessed value:
| Taxing entity | 2025 rate per $100 |
|---|---|
| North East ISD | $0.9822 |
| City of San Antonio | $0.5416 |
| Bexar County | $0.3000 |
| University Health System | $0.2762 |
| Alamo Community College | $0.1492 |
| San Antonio River Authority | $0.0183 |
| Combined (NEISD example) | about $2.27 |
The school district is the variable that moves your payment most. Northside ISD's 2025 maintenance rate was $0.6322, North East ISD's $0.9822, Judson ISD's $1.0796 and South San Antonio ISD's $1.1959 — a spread of more than fifty cents per $100 between districts inside the same county. On a $350,000 home, that difference is roughly $1,950 a year, or about $163 a month, for houses that can sit a few miles apart. Emergency services districts outside the city limits add another $0.08 to $0.10.
Check the district and the ESD for the specific address before you decide what you can afford. It changes the payment more than a quarter-point of interest rate does.
How Buyer Agent Compensation Works After the NAR Settlement
Since the 2024 settlement, cooperating compensation is no longer advertised in the MLS, and buyers sign a written representation agreement that states their agent's fee before touring homes. What did not change: sellers and builders still commonly offer buyer-side compensation, and it is still negotiated in the contract.
With a flat fee, the arithmetic is simply visible. Your agent's fee is $4,999. If the seller offers more than that, the excess may be credited toward your allowable closing costs and prepaids where your lender permits. If the seller offers less, you cover the difference. Either way you know the number before you write an offer rather than after.
