Until both parties have come to an agreement on all the contract terms and actually signed the purchase agreement such that you're in contract, neither of you are legally bound to anything, and you can withdraw your offer without any problem.
Accepting the offer An accepted offer is not legally binding until contracts are exchanged. This means a buyer can back out of the sale at any point up until contracts are exchanged. This is also the same for the seller.
Once signed by both buyer and seller, your offer to purchase becomes a legally binding sales contract, at which point you can no longer withdraw your offer unless certain contingencies are not met. For instance, if your loan does not go through, you are not obligated to purchase the home.
Can you back out of an accepted offer? The short answer: yes. When you sign a purchase agreement for real estate, you're legally bound to the contract terms, and you'll give the seller an upfront deposit called earnest money.
The subject line should include your name and Withdraw Application. Begin the letter with your salutation followed by a paragraph (or two) stating your intention to withdraw your application from consideration, and thanking them for their time. Close with your name and contact information.
In most cases, the offer to purchase contains a cooling off clause in terms of which the purchaser has the right to revoke the offer or to terminate the offer to purchase, as the case may be, by written notice delivered to the seller, within 5 (five) days of signature thereof.
To be perfectly clear, you can always back out of a real estate purchase contract at any time before closing. There's no way the seller can force you to actually purchase the home. However, if there's no valid reason for backing out as defined in the contract, you'll likely lose your earnest deposit.
