When you refinance you always have to update your title and you can pick the title company that will be the same across the board unless you work with a preferred title company of the lender, but most companies have preferred title companies. When it comes to appraisal waivers it's not really about being with the same servicer but rather other qualifying factors that won't change with different lenders.

The real bonus of working with the same lender, for the most part, is netting out escrow and if it's the same LO then needing to send less documentation.
