I was reading an article today that talked about when a buyer should lock in rates.  The article mentioned that you should be sure your lender offers a "float down" which was a chance to renegotiate your rate should there be a substantial drop. I wasn't familiar with this so I emailed one of my favorite lenders (David Stacy) and he replied saying that they do offer this feature and will fill me in on the details the next time we talk.  I'm looking forward to the info and will pass it.    Until then, if you need the expertise of a realtor, I'm  your girl!
