How to lock a mortgage rate

Couple meeting with agent
  • Focus less on the interest rate and more on timing the rate lock correctly.
  • The longer the lock period, the more the loan will cost.
  • Compare "buckets" of interest rates and discount points for the best combo.

You might never get the lowest mortgage interest rate of all time, but with a little knowledge, timing and luck, you can lock in the lowest rate available while you're shopping.

Mortgage rates fluctuate daily, making it hard to pinpoint the perfect moment to lock. To simplify the mortgage rate-lock decision, keep these things in mind: 1) It's all in the timing. 2) Compare a lineup of interest rates.

It's all in the timing

When locking a mortgage rate, don't concentrate on the media frenzy or cocktail conversations on whose rate is lower. Focus on the estimated closing date, and time your rate lock with that.

To begin, find out when your loan is expected to close and work backward to determine when to lock the rate. If you think you need 45 days to close your loan, find out what the interest rate would be if you locked it for a 60-day period.

The longer the lock period, the more the loan will cost you. Lenders do not know what the interest rates will be in the near future; they hedge the risk by offering higher rates or charging fees for longer lock periods.

Look for the sweet spot when pricing out a rate lock. The sweet spot is the combination of interest rate, term and cost you need to achieve that optimum deal. Most lenders won't lock you for less than 30 days unless you're ready to close and often offer the same rate for a 15- and 45-day period. Ask about the rate for several lock periods: 15, 21, 30, 45 or 60 days. Anything longer than 60 days gets pricey, so it might be smarter to wait until you get nearer to the closing and check again.

Watch, then act

If you feel that you have to keep your finger on the pulse of the market, Terry Connelly, an economic expert and dean emeritus at Golden Gate University in San Francisco, advises you to monitor one factor: "Watch the 10-year bond prices. As they move up, interest rates move down."

The key is to get your rate on a down day and lock for a term long enough to close the loan.

Grab it while you can. Last summer, Brian Rubin was visiting Hershey Park with his family when he received an email from me, his mortgage loan officer. The Rubins were buying a four-bedroom, 2,200-square-foot home in Westchester County, N.Y., and the rates had just dropped. Rubin could lock in at 4.375 percent for 45 days and needed to give the OK. He did via email while strolling with his family. "I was happy with the rate and could now concentrate on other things that were keeping me up like packing, moving and school starting," he says.

If you cannot close by the end of the lock period, most lenders will extend the rate or allow you to relock, but be sure to know how your lender treats it. Learn the process and the costs.

Compare a lineup of interest rates

Inquire about a lineup of mortgage rates instead of zeroing in on just one. Lenders refer to the array of interest rates as buckets, and often there is disparity among rates depending on a bank's investors.

"Think of the lender buying buckets of money at a certain interest rate and then reselling the money to the consumer," says Lou Maldonado, an account executive at Plaza Home Mortgage's New York office. Lenders are able to obtain better pricing on certain rates and should pass it on to the consumer. Ask about a series of interest rates; what will it cost to get a 4.25, 4.375, 4.5 or 4.625 percent rate locked in for the same period?

Paying discount points (one point equals 1 percent of the loan amount) might be worth it if you can get a lower rate. Divide the monthly savings into the cost to find how many months you need to recoup the expense. Compare the interest rates quoted at different prices, and you might be surprised that a lower rate could cost less overall.

Be decisive

Pick a rate that you can be happy with, and when it hits, lock the rate. The key is to be happy with the rate you were able to get and not look back.

Jennifer Lerner from Wilmington, Del., a second-time homebuyer, was waiting to lock not long ago.

"It's 4.25 (percent) right now, but the guy I'm working with seems to think it may drop to 4.125 or 4 even," she said at the time.

Is it really worth waiting for the possible drop? Jennifer waited a few days and then locked at a slightly higher rate: "We locked in at 4.375 and we are not looking back!" she says.
