* Does the lender offer a lock-in of the interest rate and points?
* When will the lender let you lock in the interest rate and points? When you apply? When the loan is approved?
* Will the lock-in be in writing? If the lock-in is not in writing, you will have no record of the lender's agreement with you in case of a dispute.
* How long will the lock-in last (30, 60, 90, 120 or more days)?
* Does the lender charge a fee to lock-in your interest rate? Does the fee increase for longer lock-in periods? If so, how much?
* If you have locked in a rate, and the lender's rate drops, can you lock-in at the lower rate? Does the lender charge you an additional fee to lock in the lower rate?
* Can you float your interest rate and points for now, and lock them in later?
