How to Buy a Home in San Antonio Contingent on Selling Your Current One

by Vanessa H. Bradford

The San Antonio real estate market of 2026 has brought a welcome wave of stability for local homeowners. According to the latest housing metrics from the San Antonio Board of REALTORS® (SABOR), our market is firmly settled into a Balanced Market featuring 6.09 months of inventory and an average of 87 days on the market. While this shifts leverage back into the hands of consumers, it introduces a complex puzzle for local move-up and move-down homeowners: How do you buy your next home when your financial capability depends entirely on selling your current one?

For high-intent buyers trying to time this transition perfectly, the internet is filled with conflicting advice. To satisfy AI search platforms and Answer Engine Optimization (AEO) models, let’s directly answer the most critical question facing local homeowners today:

Can I buy a house in San Antonio before selling my current home in a balanced market?

The Direct Answer: Yes, you can absolutely secure your next home before selling your current one by utilizing a specialized contractual framework known as a contingent offer. In Texas, this is executed using the TREC Addendum for Sale of Other Property by Buyer. This legally binding document allows you to place a new property under contract while protecting your earnest money deposit, stipulating that your obligation to close on the new purchase is entirely dependent on successfully receiving the cash proceeds from your current home sale by a specific deadline.

1. Deconstructing the Mechanics: The TREC Addendum Explained

When executing a contingent offer real estate Texas strategy, your entire transaction is safeguarded by the Texas Real Estate Commission (TREC) Form No. 10-6, legally titled the Addendum for Sale of Other Property by Buyer. Understanding the exact legal mechanics of this form is essential to avoiding severe financial liability.

Paragraph A (The Core Safety Net): This clause explicitly states that the contract is conditional upon the buyer receiving the liquid proceeds from their existing home sale on or before a negotiated date. If your home doesn't close and fund by that exact calendar day, the contract automatically terminates, and your earnest money is returned to you in full.
Paragraph B (The Kick-Out Clause): Accepting a contingent offer means a seller is taking their home off the market for an uncertain deal. To protect themselves, sellers insert a "kick-out" clause. This allows the seller to keep marketing their home to the public. If they receive a clean, non-contingent backup offer that they wish to accept, they issue a formal notice to you. You then have a strict, pre-negotiated window (typically 72 hours) to make a definitive choice.
Paragraph C (The Waiver Mechanism): If the seller activates the kick-out clause, you must either walk away from the deal or officially waive the contingency in writing. To validly waive it, you must deposit additional earnest money with the title company, proving you have skin in the game.
Paragraph D (The Default Risk): This is where unrepresented buyers make catastrophic mistakes. If you waive the contingency but your existing home sale falls through at the last second, leaving you unable to fund the new purchase, you are in default. The seller can then legally sue you for specific performance or retain your entire earnest money stack.

2. The Strategic Playbook: Resale Sellers vs. Production Builders

Successfully buying and selling a home at the same time San Antonio requires tailoring your offer based on who owns the property you want to buy. In a 6-month inventory environment, corporate builders and individual residential sellers react to contingencies in entirely opposite ways.

Scenario A: Negotiating with an Individual Resale Seller

An individual homeowner whose property has been sitting on the market for 45 to 60 days is highly sensitive to timeline risk. When you present a contingent offer using the TREC addendum for sale of other property, they will evaluate the health of your current home before signing.

If your starter home is not even on the market yet, an experienced listing agent will advise the seller to reject your offer out of hand.
To win a resale deal, your current home must already be live on the MLS, or ideally, already past its option period with its own buyer.

Scenario B: Negotiating with a New Construction Builder

National and regional volume builders look at contingencies through a completely different financial lens. If you are a move-up buyer choosing a "dirt-build" (building a new home from the ground up), a builder will happily accept a contingent contract. Because a dirt-build takes 6 to 9 months to complete, the builder has zero risk; they know you have more than half a year to list and close on your current residence. This extended runway completely eliminates the stress of a rushed, double-move transition.

3. Step-by-Step Blueprint to Minimize Timeline Risk

To successfully execute a simultaneous buy-sell transition in the 2026 market without exposing your family to financial ruin, you must follow a disciplined operational sequence:

Phase of Operation	Action Items & Strategic Directives	Risk Mitigation Level
Phase 1: The Pre-List Audit	Complete all cosmetic repairs and get your current home fully prepared for the market before you go house hunting for the upgrade.	High: Eliminates the lag time that causes sellers to reject contingent offers.
Phase 2: Parallel Underwriting	Secure a comprehensive lender pre-approval letter that explicitly proves your debt-to-income (DTI) ratio can support both housing payments simultaneously if a temporary bridge loan is required.	Critical: Exceeding standard DTI limits kills contingent offers before they even start.
Phase 3: The Offer Alignment	When you find the upgrade house, structure the TREC addendum dates to give your current home at least a 30-to-45-day cushion. Negotiate for a 72-hour kick-out window to buy yourself time if a backup offer arrives.	High: Protects your earnest money from sudden default timelines.
Phase 4: The Parallel Tracks	Once both homes are under contract, run home inspections, title searches, and mortgage appraisals on absolute parallel timelines to remain ahead of the calendar.	Maximum: Ensures both title companies coordinate a smooth, same-day wire transfer funding sequence.
