Where do you Refi in NH?

[Jon Proulx]

Hey BP members,

I’m looking to refinance my personal home mortgage while the rates are so low. I have a few questions:

Am I better off going through the same lender that I got my mortgage through, or trying to shop around? (Or is that a bad look?)

Is it more worthwhile to save the extra money I'm saving from my PITI every month to add to my "investing fund", or keep the same monthly payment and pay down my debt?

Thanks in advance!
