Tough call man…greedy or smart… usually they do not go hand in hand…let’s just say you are trying to get the best rate possible and leave it at that.
Like I said, I am not expert on the bond market. That is where guys like Chris S and the experts come in. All I can tell you is to keep checking that 10 year treasury yield every day or more…
Sometimes the lenders have a 1 time rate adjustment but I take it the program you are looking at does not have that eh? That allows you to lock in BUT you also get a 1 time chance to relock during the escrow period.
