The lock period is the period during which the lender guarantees the
rate and points. If an FRM is locked at 5.50% and 1 point for 30-days,
for example, the lender is committed to make the loan at that price
anytime within the following 30 days. Locks for longer periods are
priced a little higher. Expect to pay another 1/8 point for each
additional 15 days. During periods of market turmoil, as in 2008, the
price difference between a short lock period and a long one will be a
little higher.
If the loan has not closed by the end of the lock period, it expires;
the lender is no longer committed. If prices have not increased during
the period, the lender will usually be willing to extend the lock for a
small additional fee. If prices have increased, however, any lock
extension will be at the new higher prices. This is a risk you want to
avoid.
On a home purchase, select a period long enough to include the expected
closing date, plus a safety buffer of 15 days. On a refinance, the
required lock period depends on how long it takes the broker or lender
to process your loan. You get that period from them, then add 15 days
just in case.
If you barely qualify at today’s rates, lock as soon as possible. You
are in no position to risk an increase in rates.
If you are comfortable with the risk, you can delay the lock in order to
take advantage of the decline in price as the lock period shortens. For
example, if market rates don’t change, a 45-day price of 5.5% at 1 point
15 days later should become a 30-day price of 5.5% at 7/8 of a point.
This assumes, however, that you receive an honest reading of the market
price on the day you lock. You will if you are dealing with an internet
lender who posts your price on the internet every day. You are also safe
if you are dealing with an Upfront Mortgage Broker (UMB) who gives you
the best wholesale price on the lock day.
In other cases, you may or may not get an accurate reading. The loan
provider who knows you are in too deep to back out may up the price a
bit, so the 1/8 point will go in his pocket rather than in yours.
Indeed, he might discover that the market price went up instead of down.
With no independent check, the “market price” is what the loan provider
says it is.
You can’t prevent an avaricious loan provider from pulling that stunt
with you on a purchase transaction because you have too much at stake
and not enough time to start over. That’s why I recommend that you lock
as soon as possible.
On a refinance with any lender other than your current lender, you can
prevent it because you have a right to rescind the deal within three
business days after closing. The threat to do this will be sufficient to
protect you against any kind of chicanery.
