Did you not get the best loan you qualified for the first time?
Do you think that you will get a better rate this time?
Good enough to offset the considerable expense of getting another loan?
The answer to your question is: It depends.
Good luck and may God bless
Why are you trying to refinance so soon? Did you lock many months ago when rates were higher?
