How does Lock-In Period on Home Loan in real estate finance work?

A lock-in period on home loan is the time during which a borrower can guarantee an interest rate before formal loan approval and closing, protecting against rate increases during the application process. Understanding lock-in mechanics helps borrowers secure favorable rates while planning financing timelines strategically.
