Any experienced buyers used Guaranteed Rate?

[GL L.]

Anybody gotten quotes from GR  and used their services  or backed away?   Their Fees and  closing cost estimate seam high.   1200 lender flat  fee , no matter price of loan,  and estimated closing cost  and other fees like appraisals  of at least  7,000 for 400k loan.  I did a  First American Closing cost calculation for my state and scenario  it worked out to be around 1400.    So wonder if anyone has had experience with them good or bad?
