Sexy In sari,
Here is ther break down
a) i want to buy a house
b) I assumed this also like taking auto insurance, I meant to get better auto insurance we try multiple agency , get quote from them and decide best one
c) how to do similar to auto insurance to find a best lender for mortage, I meant there are lots of lenders available, not sure which one is suit for me.

I guess you got my point, i am not good to understand those financial/lender activity in US. If you are familiar or knowledgeable please share your idea.
Sorry for confusion.
