The lock period for a loan is set by the BrokerCriteria.dayLocks field, and the default value is 30 days.

The number of days to lock is not altered in UI but can be set using the API. If the user selects for a 7 day lock, results with 30, 45, etc day lock terms results will not be shown; anything that doesn't allow for a 7 day lock will be omitted. If a 7 day does not exist for a lender company, it will return no results.
