Lock note
Enter the day you plan to lock, your expected closing date and the lock period your lender offers. The planner shows the expiration date and how many days of buffer remain, and flags a lock that ends before closing. Every field starts empty and nothing is stored.

How it counts
Calendar days from the lock date, the way most lenders state lock periods. Your written lock confirmation controls the exact end date and time.
Rate lock questions
How much buffer should a lock have?
There is no rule. Ask your lender how long its files are taking and leave room for appraisal and document delays.
