The rate you were given could be based on numerous factors, including your own personal situation such as credit, occupancy plans, type of loan wanted/needed, etc. Direct lenders, and mortgage brokers will have different rates, on different days, they even change within the hours. Rates as far as I know, are in the low 5 range - I had a client quoted about 5.25 two days ago - and he has perfect credit, 20 percent down, etc.
Sometimes in lender will charge you discount point in order to get a certain rate. 1 discount point is equal to 1 percent of the loan.
Since so much varies based on the ledner you use, and the day you're getting a quote - it's always best to shop around, especially if you are concerned. But you only have so much time to do this, if you are already in an escrow, with timeles counting down.
