No. There is no universal three-day right to cancel a home purchase simply because you changed your mind. The federal mortgage rescission rule applies to certain credit transactions, not to every real-estate contract.

The CFPB's rescission explanation distinguishes a mortgage used to buy a home from qualifying refinances. Certain refinances or home-equity transactions secured by a principal residence can carry a right to rescind. Exceptions matter: Regulation Z includes exclusions for residential purchase-money transactions and certain same-creditor refinancings, with different treatment when new money is advanced.

Where the right applies, the clock depends on completing the required events: signing the credit agreement and receiving the required disclosure and rescission notice. For this purpose, Saturdays generally count as business days; Sundays and legal public holidays do not. That is not necessarily how a purchase contract defines its own deadlines.

Compare two situations. A buyer who regrets the price after signing a purchase contract cannot simply announce a federal three-day cancellation. A homeowner refinancing an existing principal-residence loan may have a rescission right, but the loan and documents must qualify. The transaction type changes the analysis.

A purchase contract might separately contain inspection, financing or other cancellation provisions. Their wording, deadlines and notice requirements control those contractual rights. Special statutory protections can also apply to particular transactions; this general explanation does not replace checking them.
