FSBO Agreement in San Antonio, TX: 2026 Local Guide

$12,800 – that’s the average commission a San Antonio seller saves by closing a home without an agent. If you’re ready to keep that money, you need a solid FSBO agreement that meets city rules, protects you, and moves the deal forward. This guide walks you through every clause you’ll need, the neighborhoods where FSBO sales thrive, and the 2026 market numbers that shape your pricing strategy.

Why a Custom FSBO Agreement Matters

A generic contract leaves gaps that buyers—or their agents—can exploit. In 2026 the Texas Real Estate Commission (TREC) still requires a written agreement for any residential sale over $100,000. The agreement must include:

Skipping any of these items can delay closing or expose you to liability. A well‑drafted FSBO agreement keeps the process tight, transparent, and profitable.

• Average days on market (DOM): 24 days for single‑family homes, 18 days for condos

• Interest rates: 6.75 % 30‑year fixed (average for 2026)

Neighborhoods Where FSBO Works Best

*Success rate reflects the proportion of listings that close within 45 days without an agent, according to Sellable’s 2026 data set.

Higher‑priced neighborhoods tend to have more motivated sellers who want to avoid the 5‑6 % commission that can erase $30‑$50k of equity. In those markets, buyers also expect a clean contract, so invest extra time in the agreement’s details.

Step‑by‑Step: Drafting Your FSBO Agreement

1. Gather Property Info

   • Legal description from the county clerk (Bexar County).
   • Recent tax bill and any HOA documents.

2. Choose a Template

   • Start with the Texas Residential Real Estate Purchase Agreement (TREC‑111).
   • Add local clauses: “Seller discloses that the property is located in the San Antonio Floodplain (if applicable).”

3. Set Earnest Money Terms

   • Specify amount (e.g., $7,500 for a $375,000 home).
   • Name an escrow company licensed in Texas (e.g., Lone Star Escrow).

4. Define Contingency Windows

   • Inspection: 7 days.
   • Financing: 10 days.
   • Appraisal: 10 days (optional but recommended for loan‑qualified buyers).

5. Insert Default Remedies

   • Buyer defaults → retain earnest money as liquidated damages.
   • Seller defaults → return earnest money plus $1,000 penalty.

6. Add Disclosure Attachments

   • Texas Property Disclosure Form.
   • Lead‑Based Paint Addendum (if home built before 1978).
   • Flood Zone Disclosure (if applicable).

7. Review with a Real Estate Attorney

   • A 30‑minute consult in San Antonio typically costs $250‑$350.
   • Many FSBO platforms, including Sellable, offer a vetted attorney network at a flat $199 rate.

8. Sign and Distribute

   • Use electronic signatures (DocuSign, Adobe Sign) to speed up execution.
   • Send a copy to the buyer, their lender, and the escrow officer.

Following these eight steps gives you a contract that meets TREC standards, protects your equity, and looks professional enough to satisfy even a buyer’s agent.

Common Pitfalls and How to Avoid Them

• Skipping the flood‑zone addendum – San Antonio’s River Walk area still experiences occasional flooding. Forgetting this disclosure can trigger a buyer’s right to rescind and expose you to a lawsuit.
• Leaving the closing date open‑ended – Buyers often request “flexible” dates. Pin down a specific deadline (e.g., “Closing shall occur on or before June 30, 2026”) to keep the timeline realistic.
• Accepting a low earnest money amount – A $500 deposit looks weak on a $400k home. Insist on at least 1 % to demonstrate buyer commitment.
• Relying on verbal agreements – Everything from price adjustments to repair credits must be written. Use amendment forms rather than email threads.

Frequently Asked Questions

1. Do I need a real‑estate license to draft my own FSBO agreement?
No. Texas law permits any party to create a purchase contract, but the document must meet TREC standards. Having an attorney review it protects you from missing required language.

2. Can I require a buyer to use a specific escrow company?
Yes. The agreement may name a licensed escrow agent, but the buyer can suggest an alternative if both parties consent in writing.

3. What happens if the buyer’s loan falls through after the financing contingency expires?
If the buyer cannot secure financing within the 10‑day window, the contract terminates and you keep the earnest money as liquidated damages, provided the contingency language is clear.

4. Are there any San Antonio‑specific disclosures beyond the state form?
Homes within the 100‑year floodplain must include a FEMA flood‑zone disclosure. Additionally, properties in the historic King William district require a preservation ordinance notice.

5. How does Sellable’s pricing tool stay current?
Sellable pulls MLS, public records, and recent sales data daily for the San Antonio metro area. The algorithm adjusts for neighborhood trends, giving you a price range that reflects 2026 market conditions.
