MBS are down. If your lender has already issued rates this morning, a reprice for the worse may be potential.  If you don't have rates yet, they won't be looking very good when they arrive.

We're down 9/32nds on the 5.5% coupon.  This will probably already be baked in to your lenders rate sheets for the day, so the float/lock decision depends more on the rest of the day.
