Change mortgage rate 1 week before closing

[Andy Wilson]

Hi BP,

I recently had contract to buy a SFH with 30 yr fixed 4.2% for investment property. I only have a week before closing but I realized the recent mortgage rate significantly dropped. In this case, is there any way I can lower mortgage rate? My loan officer has kept saying he would see what he can do for a couple of weeks now, but nothing has been done.. Hope someone can advise...
