However, a locked-in rate could also prevent you from taking advantage of price decreases, unless your lender is willing to lock in a lower rate that becomes available during this period. A loan commitment is the lender's promise to make you a loan in a specific amount at some future time. Generally, you will receive the lender's commitment only after your loan application has been approved. Some lenders have preprinted forms that set out the exact terms of the lock-in agreement. Others may only make an oral lock-in on the telephone or at the time of application.
Oral agreements can be very difficult to prove in the event of a dispute.
Some lenders' lock-in forms may contain crucial information that is difficult to understand or that is in fine print. Thus, it is wise to obtain a blank copy of a lender's lock-in form to read carefully before you apply for a loan. If possible, show the lock-in form to a lawyer or real estate professional. This record may be useful in the event of a dispute. Lenders may charge you a fee for locking in the rate of interest and number of points for your mortgage.
