Lender Loyalty to one or many?

[Erik Sherburne]

Curious how much loyalty you have to a single lender.  I've worked with a few and there are a couple I really like.   I'm refinancing a property now and there are three that are giving me rates and closing costs.     Current lender can wave appraisal fee, lender I worked with on another loan can give me $500 off the next one, etc. etc.    I do believe in loyalty.  I do believe in relationships as being fundamental to success.    Do I go with the best deal?   Use the best deal on this one and the other lender on the next one?  Stick with one lender unless the numbers are way off?
