Investopedia explains 'Cooling-Off Rule'
Different types of transactions will have different cooling-off rules, and not all types of contracts have such provisions. Typically this period will be three days; however, it is imperative that all the rules and regulations listed in the fine print are read before entry into a contract.
In the U.S., federal law usually requires a three-day penalty-free period for the rescission/withdrawal from any refinancing contract associated with the primary residence.
