Third (3rd) Party Financing Addendum Form

This addendum to real estate purchase contract is often attached to a purchase agreement so that both the seller and buyer know who is financing the sale. It’s not used if the buyer is receiving financing from the seller. It can also null the printable purchase and sale agreement if the buyer cannot receive the financing that they need to buy the home or property.

Use this guide and template to help you get started with the third-party financing addendum.

What Is a Third-Party Financing Addendum?

A third-party financing addendum is added to the sales contract to outline the terms of the loan the buyer is using. It can be used for conventional, FHA, or VA loans. The sales contract is contingent on the buyer securing the loan for the mortgage.

If the buyer cannot receive the loan, the contract will be void. The seller will typically need to be pre-approved for the loan or the financing before they can fill out the third-party financing addendum.

What Are the Types of a Third-Party Financing Addendum?

There are several different types of third-party financing that are used and may require this addendum.

A conventional financing addendum is used for a buyer who is using a loan from the Association of Realtors. This is one of the most common loan types and is used by most people who do not qualify for one of the other financing options.

An FHA or VA financing addendum is used when the buyer is receiving financing from the VA or FHA. VA loans are home loans given to veterans or service members. They can also be given to spouses and dependents of veterans in some cases.  FHA loans are given by the Federal Housing Administration and are a common financing option.

There’s also a reverse mortgage financing addendum. This is usually used by people who are 62 years or older and allows the seller to get funds for the property in exchange for the homes’ equity.

USDA financing addendum is when there is a property being sold in a suburban or rural area to a buyer who couldn’t qualify for a traditional loan.

Why Use a Third-Party Financing Addendum?

A third-party financing addendum can be used anytime the buyer is receiving financing for a loan. It’s always a good idea to have one because it allows the buyer to terminate the sales contract if they cannot receive the proper funding.

It allows the buyer to have any earnest money they gave refunded back to them. Keep in mind that the buyer still has to give written timely notice if they are canceling the purchase agreement. Otherwise, they may be in breach of the sales contract. Most states require a notice of at least three days before closing.

If you are the buyer, let the seller know as soon as you can that you are not receiving the loan and need to cancel the sale. Keep in mind that the addendum does not require the buyer to obtain the funding in a certain timeframe. This means that the buyer can opt out of the sale as soon as they feel that the approval of the funding will not be given.

The third-party financing addendum can protect the buyer and seller from potential loan issues. Even if someone is pre-approved for a loan, they might not be able to secure the amount they need to purchase the home. Having the addendum in place can give both parties peace of mind when it comes to financing and loan approval.

What Are the Basic Components of the Addendum?
