Real Estate Contracts
What Is a Real Estate Addendum?
A real estate addendum is a document added to a purchase contract to modify, clarify, or add terms not included in the original agreement. Addenda (plural) are legally binding when properly executed and become part of the contract.
Understanding addenda is important for the licensing exam because they are how most contract modifications are made in practice — and because errors in addenda can create legal liability for agents.
Common Types of Addenda
Inspection Addendum
Added after a home inspection reveals issues. Allows the buyer to request repairs, a price reduction, or credits in lieu of repairs. Creates a negotiated agreement about property condition that becomes part of the contract.
Financing Addendum
Specifies loan type, amount, interest rate, and the deadline by which financing must be secured. Protects the buyer's earnest money if they cannot obtain the agreed loan terms.
Seller Financing Addendum
Details the terms when the seller acts as the lender — interest rate, payment schedule, balloon payment date, and default provisions. Required when seller financing is part of the transaction.
Short Sale / Bank Approval Addendum
Used when the property is being sold for less than the mortgage balance. Makes the contract contingent on lender approval of the short sale, which can take months.
How Addenda Affect the Contract
When an addendum conflicts with the original contract, the addendum generally controls — because it is the later, more specific document. Agents should ensure addenda clearly reference the original contract by date and property address, and that both parties sign and date the addendum.
Agents can present and explain pre-printed addenda forms provided by their state association or brokerage. However, drafting custom legal language is practicing law — which agents are not licensed to do. When a situation requires custom contract language, refer to a real estate attorney.
