Any benefits to buying a primary residence house cash then refi?

[Nick Arenaso]

This is for my personal residence - not an investment property.

My new home will cost 750K.  I am able to comfortably put 550K down, then stretch to pay the rest by dipping into savings/stock investments.

Is there any significant benefit to doing an all cash deal initially, then refinancing later on to get liquid again?  I dont anticipate having any trouble with the bank to get my loan so i am wondering if it is worth the hassle.
