If you are wondering what a purchase agreement is when selling a house, the short answer is that it is the legally binding contract that defines the purchase price, closing timeline, contingencies, and the responsibilities both the buyer and seller must fulfill before ownership transfers.
Many homeowners assume accepting an offer means the sale is final.

Understanding the purchase agreement before you sign can help you avoid costly disputes, make informed decisions during negotiations, and keep your home sale on track from contract to closing.
This guide explains what a purchase agreement is when selling a house, what it includes, when it becomes legally binding, and what every seller should review before signing.

What Should Sellers Review Before Signing A Purchase Agreement?

| Situation | What Happens |
|---|---|
| Both parties approve the change | The purchase agreement is amended |
