best lender for refinance personal house

[Kevin McDonald]

Hello,

I am looking to refinance my personal house now that rates are so low. I see tons of advertisements popping up on my social medial accounts (better.com, rocket mortgage, etc....) .  I have called a few but I want to make sure I am getting the best deal I can.  Before I start to call more places does anybody have any recommendations on the best deal (lowest rate with the least amount of cost to refinance)?
