Just got an accepted offer, however anticipated closing date of Sept 20. My lender offers a 30 day rate lock or a 60 day (which obviously I would pay for) or a floating rate which I can lock at anytime. I like where the rates have been lately, I believe at 4.25 yesterday...just not sure what to do. Would rather not pay for a 60 day lock but afraid of rates going up to 5% in the very near future. Any advice?
