Similarly, real estate has "name brand" brokerages, but an agent in that name brand brokerage might be LOUSY!!
As a licensed real estate agent, I'm not comfortable with talking about rates, loans, etc. This is an area that is outside the scope of my license. I can sell houses, and I do! And while I know "of" the loan process, and can give general advice, your best bet is to contact a lender that comes with a high reference -- from a reliable source.
A good loan rep will be able to compare "apples" to "apples" and see if you are, in fact, getting very low interest rates, that there are no hidden fees, back-end mark ups, etc.
I recommend contacting either:
