<prompt> Human: Last week, after shopping around rates for our new home, my wife and I sat down with the lender and verbally locked the interest rate. He sent us digital documents this week, but by the time we got them, rates had inched slightly lower than when we had met. When I told him that we did not sign it because rates had dropped, he said he could not honor the new rate. What should I do? I would ditch this lender in a second but they are helping towards closing costs because we are buying a home form their parent company. Note: On the digital document he sent, it explicitly says: The rate cannot been locked until the homeowner as well as lender have both signed the agreement documentation.  <response>: Shop around. Show a competitor the terms, and chances are good they will beat them.
