I feel your pain. I finally gave up and locked in at 5.75% today. Much higher than the 4.875 when I filled out the loan papers. Took two weeks to find a property and get an accepted contract to my lender. At that time it was at 5.25, another lender told me "ride it out, rates can't stay like this", I asked others, they also said "ride it out". I missed better rates days after day. Bitter but I'll have to get over it.
