Final answer:
The common period for a buyer to revoke an offer after receiving a property condition disclosure is often 3 days. This allows review of the property's disclosures and the option to rescind the offer if the property's condition is unsatisfactory.
Step-by-step explanation:
When a buyer is given a property condition disclosure after making an offer on a home, the specific timeframe in which they must be given to revoke the offer and have the earnest money returned varies by state law. However, a common period provided in many regions is 3 days (c). This is a standard contingency period that allows the buyer to review the disclosures and possibly rescind their offer if they find something unsatisfactory with the property's condition.
