Third-Party Financing Addendum & the Option Period

This page stays focused on TREC No. 40-11 and its financing deadlines. For the complete form family, the promulgation rule, and the form-selection map, use the TREC promulgated contract forms guide.

What does the Third Party Financing Addendum do?

The Third Party Financing Addendum, TREC No. 40-11, attaches to the contract when the buyer will fund the purchase with a new loan from a lender. It describes the loan, and it can make obtaining that loan a condition of the sale. The base One to Four Family contract does not by itself protect a buyer who cannot get financing.

The form is adopted by reference at 22 TAC Section 537.47 and has been effective since January 3, 2025. Because it adds terms rather than changing terms already agreed, it is an addendum and is normally attached when the contract is formed. It is not an amendment.

Paragraph 1 sets out seven financing types, and the exam has been known to test the ones candidates forget:

Two of those are easy to miss. A Texas Veterans Land Board loan sits at box B as its own type, separate from the VA guaranteed loan at box D, and confusing the two is a Texas-flavoured trap. A reverse mortgage at box F is a financing type the addendum contemplates.

The exam wants you to connect the situation to the form. A buyer getting a new lender loan points to the Third Party Financing Addendum every time, whichever of the seven types it is.

Buyer approval and the termination deadline

Paragraph 2 of the addendum builds approval out of two separate approvals, and the contract is not financed until both are obtained. Paragraph 2 says approval "will be deemed to have been obtained when Buyer Approval and Property Approval are obtained," and adds that time is of the essence for that paragraph.

Buyer Approval, Paragraph 2A, is about the borrower. The addendum defines it precisely: it is obtained when the terms of the loan are available and the lender determines the buyer has satisfied all of the lender's requirements related to the buyer's assets, income and credit history. If the buyer cannot obtain it, the buyer may terminate within a negotiated number of days after the effective date.

Property Approval, Paragraph 2B, is about the house. It covers the lender's underwriting requirements for the property, expressly including appraisal, insurability, and lender required repairs, and it runs to a different deadline entirely.

Terminating takes two documents, not one

This is the detail candidates lose. Under both 2A and 2B, the buyer terminates by giving the seller (i) notice of termination and (ii) a copy of a written statement from the lender setting forth the reasons for the lender's determination. A notice alone does not do it. The lender has to put its reasons in writing and that writing goes to the seller.

Read those last two cells together, because they are the trap. Missing either deadline does not leave that protection open. After the 2A deadline, the contract is no longer subject to Buyer Approval; after the 2B deadline, Property Approval is deemed obtained. In either case, that termination route is gone and a later failure to close can put the buyer's earnest money at risk.

The addendum can be attached with no financing condition at all

Paragraph 2A is a check-one-box choice, and the second box reads: "This contract is not subject to Buyer obtaining Buyer Approval." That box exists for a buyer who wants a lender loan described in the contract but is not making approval a condition of the sale, which is how a financed offer competes with a cash offer.

So "the buyer is using a lender, therefore the buyer is protected" does not follow. The addendum being attached tells you the financing type. Which box is checked in Paragraph 2A tells you whether there is a contingency.

Buyer Approval, Property Approval, and the option period are three different routes

The Third Party Financing Addendum contains two approval routes, and the option period is a third, separate exit. Buyer Approval concerns the borrower and loan terms. Property Approval concerns the lender's underwriting of the property. The option period gives the buyer an unrestricted right to terminate during a negotiated window when the option fee is paid on time.

This is the distinction that separates strong candidates. The three routes can exist at the same time, but their triggers, deadlines, and required documents are different.

A buyer often has all three routes at the start of a deal. The option period supplies the broad exit. Paragraph 2A protects against a defined Buyer Approval failure when its first box is selected. Paragraph 2B addresses the lender's property-underwriting decision. Read the facts, identify the route, and then apply that route's deadline and document requirements.

Appraisal protection appears in two forms

Appraisal appears in two forms, but those forms do not create one interchangeable right. Paragraph 2B of the Third Party Financing Addendum names appraisal as one of the lender's underwriting requirements. TREC No. 49-1 has three mutually exclusive choices. Boxes (1) and (2) waive or partly waive the buyer's existing Paragraph 2B appraisal protection. Only box (3), Additional Right to Terminate, creates a separate right tied to a stated appraised value. A candidate who has been told the financing addendum "does not cover appraisal" has been told something the form contradicts.

Read Paragraph 2B and the words are there:

If Buyer's lender determines that the Property does not satisfy lender's underwriting requirements for the loan (including but not limited to appraisal, insurability, and lender required repairs) Buyer may terminate this contract on or before the 3rd day before the Closing Date.

So the difference is not appraisal versus no appraisal. It is what triggers the right.

Property Approval versus Form 49-1 box (3)

The practical gap between the two rights

The practical gap is this. A low appraisal does not by itself trigger Paragraph 2B. The lender must determine that the property fails its underwriting requirements because of the appraisal. A conventionally financed buyer whose lender would otherwise approve the property may need the separate value-based protection in box (3) of TREC No. 49-1.

For the exam, keep the trigger in view rather than the topic. Borrower approval is Paragraph 2A. Property fails the lender's requirements is Paragraph 2B. Value below a number the buyer named is the separate appraisal addendum.

This guide quotes Paragraph 2B from the addendum itself. The description of TREC No. 49-1 comes from the rule adopting it, 22 TAC Section 537.56, and from box (6) of the Notice of Buyer's Termination of Contract, which records a termination under Paragraph (3) of that addendum with a copy of the Appraisal delivered to the seller.

What the agent may and may not do

A sales agent completes the Third Party Financing Addendum by filling in its blanks and attaching it when the transaction uses applicable third-party financing, working under a sponsoring broker. An agent may not draft custom financing, appraisal, or contingency language. Under TREC Rule 537.11, license holders are prohibited from drafting clauses such as escalation, appraisal, or contingency clauses.

Choosing and completing the promulgated addendum is proper. Writing new contract language is not.

If a deal needs terms the promulgated forms do not provide, that is a job for an attorney. Drafting language that defines the parties' rights and remedies is the unauthorized practice of law, which a license holder may not do.

Frequently asked questions

When do you use the Third Party Financing Addendum?

The Third Party Financing Addendum is used when all or part of the purchase price will be financed by a third-party lender. Whether the contract is subject to Buyer Approval depends on the Paragraph 2A box selected. Property Approval has its own Paragraph 2B rules.

What happens if the buyer misses the financing termination deadline?

After the negotiated Buyer Approval period passes without the required termination documents, the contract is no longer subject to the buyer obtaining Buyer Approval, and the earnest money can be at risk if the buyer later cannot close. Property Approval has its separate deadline on or before the third day before closing.

Is the option period the same as the financing contingency?

No. The option period is a broad right to terminate for any reason when the option fee is paid on time. Paragraph 2A applies when the buyer cannot obtain Buyer Approval within its negotiated deadline. Paragraph 2B applies when the lender determines the property fails underwriting requirements. The buyer can hold these rights at the same time, but each has its own trigger, deadline, and required documents.

Does the Third Party Financing Addendum cover a low appraisal?

Partly, and this is commonly taught wrong. Paragraph 2B names appraisal expressly, as one of the lender's underwriting requirements for the property, alongside insurability and lender required repairs. What Paragraph 2B needs is for the lender to decide the property fails those requirements. A buyer who is approved anyway but does not want to pay above the appraised value has no Paragraph 2B right, and that is the gap box (3) of TREC No. 49-1 fills. Be careful with that form: its other two boxes waive the Paragraph 2B right rather than adding to it.

When are the earnest money and option fee delivered?

In current TREC Form 20-19, both the earnest money and the option fee are delivered to the escrow agent within three days after the effective date. If the last day falls on a Saturday, Sunday, or Legal Holiday as the contract defines that term, the deadline extends to the end of the next day that is not one of those days. The option fee is credited to the sales price at closing.

Practice questions

1. A buyer will purchase using a new conventional loan and wants financing to be a condition. Which form applies? A. Amendment B. Third Party Financing Addendum C. Seller Financing Addendum D. Loan Assumption Addendum

Answer: B. A new lender loan as a condition uses the Third Party Financing Addendum. Seller Financing is owner carryback, and Loan Assumption is taking over the seller's loan.

2. The buyer cannot obtain Buyer Approval and does nothing before the negotiated Paragraph 2A deadline passes. What is the likely result? A. The contract automatically terminates with a refund B. The buyer keeps the financing termination right indefinitely C. The financing termination right lapses and earnest money is at risk D. The seller must return the option fee

Answer: C. After the negotiated 2A deadline passes, the contract is no longer subject to Buyer Approval. Property Approval has its own 2B deadline. Missing the applicable deadline closes that termination route and can put the earnest money at risk if the buyer later cannot close.

3. Which statement best distinguishes the option period from the approval-based termination rights in Form 40-11? A. They are the same right with two names B. The option period requires a reason, financing does not C. The option period allows termination for any reason, while Paragraphs 2A and 2B require the applicable approval failure and specified documents D. Only the financing right costs a fee

Answer: C. The option period is a broad, any-reason exit supported by timely payment of the option fee. Paragraph 2A instead turns on Buyer Approval, and Paragraph 2B turns on the lender's property-underwriting determination. Both financing routes require notice and the lender's written statement of reasons.

4. A conventionally financed buyer wants a right to terminate if the appraised value is below $425,000, even if the lender would otherwise approve the property. Which form and choice provide that protection? A. Third Party Financing Addendum, Paragraph 2A B. Third Party Financing Addendum, Paragraph 2B C. TREC No. 49-1, box (3), Additional Right to Terminate D. TREC No. 49-1, box (1), Waiver

Answer: C. The buyer wants a separate right tied to a stated appraised value, even if the lender would otherwise approve the property. That is TREC No. 49-1, box (3). Paragraph 2B can apply when an appraisal causes the lender to determine that the property fails underwriting. Boxes (1) and (2) of Form 49-1 waive or partly waive that existing Paragraph 2B protection.

Sources and methodology

This guide teaches exam-level contract mechanics, not legal advice. Every claim about a form is cited to the paragraph it comes from.

• The addendum is the Third Party Financing Addendum, TREC No. 40-11, effective January 3, 2025 and adopted by reference at 22 TAC Section 537.47. The seven financing types are Paragraph 1, boxes A through G.
• The two-approval structure, and that time is of the essence for that paragraph, are Paragraph 2. Buyer Approval, its definition by reference to the buyer's assets, income and credit history, the negotiated day count, and the not-subject-to-approval checkbox are Paragraph 2A. Property Approval, its coverage of appraisal, insurability and lender required repairs, and the deadline on or before the third day before the Closing Date are Paragraph 2B.
• The requirement to deliver both a notice of termination and a copy of the lender's written statement of reasons appears in both Paragraph 2A and Paragraph 2B.
• The FHA and VA provision, including that the three-day notice requirement in Paragraph 2B does not apply to it, is Paragraph 4. The vendor's and deed of trust lien requirement is Paragraph 3. The lender's authority to report approval status to the seller is Paragraph 5.
• The separate appraisal form is the Addendum Concerning Right to Terminate Due to Lender's Appraisal, TREC No. 49-1, adopted at 22 TAC Section 537.56. It carries three mutually exclusive boxes. Boxes (1) and (2) waive or partly waive the Paragraph 2B appraisal protection, and only box (3) adds a value-based right to terminate. Box (3) requires the appraised value to fall below a stated figure and requires the buyer to deliver a copy of the appraisal to the seller, which is what box (6) of the Notice of Buyer's Termination of Contract, TREC No. 38-8, records. The form's heading limits its use to transactions where the Third Party Financing Addendum is attached and no FHA or VA financing is involved.
• The option fee, the unrestricted right to terminate, and the three-day delivery of the earnest money and option fee to escrow are Paragraph 5 of the current One to Four Family Residential Contract (Resale), TREC No. 20-19, effective July 1, 2026.
• The limits on what a license holder may draft are TREC Rule 22 TAC Section 537.11.
• Form versions change periodically through the TREC Broker-Lawyer Committee. Use the current promulgated version in practice.
