What is Third-Party Financing Addendum?

A third-party financing addendum is an additional contract that supplements the original sale contract. It is commonly used in real estate transactions.

The purpose of the third-party financing addendum is to provide the buyer with an option to terminate the sale contract if they cannot obtain lender financing due to the reasons mentioned in the document.

What is Third-Party Financing Addendum (TXR 1901, TREC 40-9)?

A third-party financing addendum is an official document added to the original contract made between two parties. 

An addendum can be made for any type of contract between two parties. A third-party financing addendum is created when the buyer obtains external financing from another party not originally involved in the main contract. 

Third-party financing addendum TXR 1901/TREC 40-9 are addendum documents promulgated by the Texas Real Estate Commission (TREC). 

TXR 1901 is the code for financing addendum and TREC 40-9 is the document identified for the TREC where the number 40-9 represents the version number of the same document. 

TREC 40-9 has replaced the old version of the same addendum 40-8 with a few minor updates. 

A third-party financing addendum is an additional contract that outlines the terms and conditions of financing arrangements for the mortgage or property purchase agreement. 

It outlines different situations and responsibilities of the buyer to fulfill the terms of the original sale contract by arranging third-party financing. 

The addendum becomes a contractually binding document when signed by both parties. The buyer then becomes liable to arrange the mortgage loan and fulfill the terms of the addendum. 

If the buyer fails to meet the terms of the addendum and does not notify the seller, the original sale contract also becomes void. 

Why Use a Third-Party Financing Addendum? 

Addendums are separate contracts that are attached to the original contract between two sides. Financing addenda are commonly used in the real estate sector for several purposes. 

A third-party financing addendum is used to bound the buyer to secure third-party financing or a mortgage loan to complete the original transaction. 

Similarly, both parties can create a different addendum for clarification, amendments, and addition/deletion of certain clauses in the original sale contract without changing the context of the contract. 

Common reasons for using addenda include: 

  • Adding or deleting a clause in the original contract – for example, arranging a mortgage loan by the buyer. 
  • Either the buyer or the seller requires a date extension in the original contract. 
  • One or both parties want to change certain terms of the original contract. 
  • One or both parties cannot oblige a certain clause in the contract. 
  • External factors affecting both parties that were not included in the original contract can be outlined in the addendum contact.

Also, both parties should clarify the waivers or omissions are different from contract termination clauses for both sides.
