Can Buyer A rescind his mortgage if he changes his mind about the purchase two days after closing?

In California, once a mortgage closes, the buyer generally cannot rescind the mortgage simply because they have changed their mind about the purchase. The right of rescission under the federal Truth in Lending Act applies primarily to certain types of loans, such as those involving a borrower's primary residence and does not give a blanket period for canceling a mortgage after closing. The period for rescission is typically three business days after the loan closing, but this only applies to specific types of loan transactions, not the purchase of real property itself.

In the case of Buyer A, while a new homeowner may have some protections under consumer protection laws, once the transaction is finalized and closed, they cannot simply decide to back out without a valid legal reason. Thus, the conclusion that Buyer A cannot rescind the mortgage is consistent with standard practices in real estate transactions and applicable laws.
