If
rates increase during the lock period and your lock expires,
most lenders will let you re-lock at the new, higher
rate or points. If
rates decrease during the lock period and your lock expires,
lenders usually will charge a penalty to take advantage
of the new, lower rates. For a fee, some lenders
allow a "float-down" option which allows you
to take advantage of decreasing interest rates. Once a
lock expires, be prepared to renegotiate the rate and points.
Unless
you have the option to float-down, most lenders will
not budge unless rates drop substantially (3/8 percent or
more). Lenders incur fees when they lock loans. If
lenders were to allow borrowers to cancel a lock every
time rates improved, they'd spend too much time re-locking
rates, and the increased costs would have to be passed
to borrowers.
Most
lenders will let you lock an interest rate only in
connection with a specific property. Some lenders offer
lock-and-shop programs which let you lock a rate before
you find your home. Both
programs can be valuable when rates are rising.
Most lenders offer long-term
locks for new construction. Since these locks tend to
be relatively long, they can be expensive. An up-front
deposit is sometimes required also. Most long-term new
construction locks offer a float-down.
