What Is an Addendum in Real Estate?

A real estate addendum is a written document that adds, removes, or clarifies terms in a signed purchase agreement. FSBO sellers often use addendums to confirm inspection results, closing dates, or repair agreements after both parties sign the main contract.

โœ… How Real Estate Addendums Work

  • Attach to the purchase agreement: addendums become part of the contract once signed by both buyer and seller.
  • Used for clarifications: such as extending the closing date, changing the sale price, or specifying repairs after inspection.
  • Different from an amendment: an amendment changes contract terms directly, while an addendum adds new information or documents.

๐Ÿ“„ Why Addendums Matter in FSBO Transactions

Addendums keep a sale on track when situations change after signingโ€”such as appraisal results, financing delays, or repair negotiations. They help FSBO sellers and buyers avoid confusion while maintaining a binding contract.

  • Document every change for transparency
  • Ensure both parties sign and date each addendum
  • Keep all addendums with the final closing documents

๐Ÿ“Œ Common Real Estate Addendums

  • Inspection or repair addendum
  • Financing or appraisal addendum
  • Closing date extension
  • Title or HOA disclosure addendum

Each helps document a change while keeping the original purchase agreement valid.
