Whether you manage a full pipeline or run your own deals solo, this guide covers how Texas TCs and solo agents navigate TREC requirements: the 3-day earnest money deadline, option period math, calendar-day calculations, and the 2025 TREC form updates.
Critical Texas deadlines
"Being able to upload contracts and have Ava read them and extract all the important details and dates is most valuable. It is a big time saver and just having another set of eyes creates a checks and balance system I can rely on and feel confident about."
Whether you are a transaction coordinator managing ten open files or a solo agent closing your first Texas deal, the rules are the same and the stakes are identical. The Texas Real Estate Commission (TREC) publishes all promulgated contract forms that licensed agents and brokers are required to use, creating a precise, rule-based system where deadline math starts the moment the last party signs.
Texas real estate transactions operate under rules set by the Texas Real Estate Commission (TREC), which promulgates standardized contract forms all licensed agents and brokers must use. This makes Texas one of the most form-specific real estate markets in the country, with a precise deadline structure that is consistent across the state.
The most critical concept is the effective date: the date on which the last party signs and delivers the fully executed contract. This single date triggers a cascade of calendar-day deadlines that must be met precisely, including the 3-day earnest money delivery rule, the option fee, and the option period itself. Per a 2021 TREC rule change, both the earnest money and the option fee are now delivered to the title company rather than the seller.
The January 2025 TREC updates added Paragraph 6E(11) mold remediation certificate requirements and introduced the T-47.1 Declaration as a notary-free alternative to the T-47 Affidavit for existing surveys. Farm and Ranch transactions use TREC Form 25-16 and involve additional complexity around mineral rights, water rights, and agricultural development district status.
Per a 2021 TREC rule change, both the earnest money and the option fee are delivered to the title company rather than the seller. Closing is coordinated with the title company, which handles the closing disclosure review, document execution and funding.
Navigate Texas's 30-60 days process with precision. Each phase below lists the work it carries and the deadlines that govern it.
Important: All TREC deadlines use calendar days, not business days. Weekend and holiday exceptions roll the deadline to the next business day.
| Milestone | Texas deadline |
|---|---|
| Contract Execution | Day 0, effective date determines every future deadline |
| Earnest Money | Within 3 calendar days of effective date, to the title company |
| Option Fee | Within 3 calendar days of effective date, to the title company |
| Option Period | 7 to 10 negotiated calendar days, expires at 5 PM local time at the property location TREC Form 20-18 Paragraph 5 |
| Financing | Financing deadline per contract Paragraph 3 |
| Survey | Survey deadline per Paragraph 6C if applicable |
| Final Walkthrough | Typically 24 to 48 hours before closing |
| Closing | Day 30 through 60, closing date as specified in contract |
Quick answers to the TREC deadline questions that come up on every deal, whether you are coordinating for a client or managing your own transaction.
In Texas, the option period is a negotiated window of calendar days, typically 7 to 10, starting from the contract effective date. The buyer pays a non-refundable option fee to the title company and retains the unrestricted right to terminate the contract for any reason until the period expires at 5 PM local time at the property's location, per TREC Form 20-18 Paragraph 5.
TCs managing multiple files and solo agents closing their own deals face the same precise deadline. Missing the option period expiration costs the buyer their unrestricted termination right, which is the most common source of earnest money disputes in Texas transactions.
Ava reads the option period length from your uploaded TREC contract, calculates the expiration in calendar days with the 5 PM cutoff, and creates a deadline task on your deal timeline automatically.
Per TREC contracts, earnest money must be delivered to the title company within 3 calendar days of the effective date. If the third calendar day falls on a Saturday, Sunday, or legal holiday, the deadline extends to the next business day. Per a 2021 TREC rule change, both the earnest money and the option fee now go to the title company rather than the seller.
TCs with five open files and solo agents with one deal face the same 3-day window. Ava reads the effective date on upload, creates an earnest money task immediately, and flags any weekend or holiday rollovers so you know the actual due date before it catches anyone off guard.
TREC Form 20-18, the One to Four Family Residential Contract (Resale), is the Texas Real Estate Commission's standard purchase agreement for residential resale transactions, required for use by all licensed Texas agents and brokers. The January 2025 update added Paragraph 6E(11) requiring sellers to provide mold remediation certificates from the five years before closing, and introduced the T-47.1 Declaration as a notary-free alternative to the T-47 Affidavit for existing surveys.
Ava reads Form 20-18 including all 2025 provisions in real time on upload. No pre-setup, no template configuration, and no manual re-entry of extracted fields. The effective date, option period, earnest money deadline, and financing paragraph all appear in your deal timeline within seconds.
Texas TREC contracts use calendar days for all time periods, including the 3-day earnest money delivery rule, the option period, and inspection deadlines. The single exception: if a deadline falls on a Saturday, Sunday, or legal holiday, it rolls to the next business day. This differs from states such as Washington and Oregon, where many of the same periods are counted in business days.
TCs who work across multiple states tell us this is the most common source of miscalculation on Texas deals. Ava applies calendar-day math automatically from the contract terms and flags every weekend or holiday rollover before you have to recalculate manually.
