Refinancing - credit ramifications of moving a mortgage to another lender

[Francis A.]

Hi,

I have been wondering about this. 

When a lender (Finance company # 1) issues a mortgage and then turns around and sells it to another lender (Finance company # 2). Does your credit take a hit if you were to take that mortgage and refinance with yet another lender (Company # 3) 6 months after the sale of the mortgage? What are the ramifications if any?

Thanks so much!!!
