California runs the nonjudicial sale through Cal. Civ. Code §2924: a recorded notice of default, a three-month wait, then a notice of sale recorded and published at least twenty days before the auction. Code Civ. Proc. §580b bars any deficiency on a purchase money instrument given to the vendor, and §580d bars one after any nonjudicial sale, so a California carryback is functionally nonrecourse. That protection cannot be waived in the note. Carryback sales also fall under Civ. Code §§2956 to 2967, and §2966 makes the holder warn the borrower between 90 and 150 days before a balloon falls due.
Texas pairs a fast trustee's sale with strict paperwork. Tex. Prop. Code §51.002 requires a 20-day notice of default and opportunity to cure on debt secured by a borrower's residence, then 21 days' written notice of sale, with the auction held on the first Tuesday of the month at the county courthouse. Deficiency survives under §51.003 for two years, subject to a fair market value offset. A seller financing a house that still carries a bank lien must deliver the seven-day disclosure to the buyer and every lienholder under §5.016, and wraparound loans fall under Chapter 159 of the Texas Finance Code.
Florida uses mortgages rather than deeds of trust, and foreclosure runs through the circuit court under Fla. Stat. Chapter 702. The tax trap catches nearly every private lender: documentary stamp tax is due on the note under Fla. Stat. §201.08 and on the recorded instrument, and most District Courts of Appeal hold the instrument unenforceable until the tax is paid, as in Klein v. Royale Group.
New York is judicial only. Foreclosure proceeds under RPAPL Article 13, a residential home loan triggers the 90-day pre-foreclosure notice of RPAPL §1304 plus the filing under §1306, and RPAPL §1301 forces an election of remedies, so suing on the note forfeits foreclosure without leave of court. Where a revocable living trust holds title, confirm the trustee powers before the instrument reaches the clerk and budget for mortgage recording tax under Article 11 of the Tax Law.
