A "good rate" depends on the borrower's individual situation — factors like loan term and amount, along with credit score and income, can affect rates. Mortgage interest rates are also constantly changing. The estimate you receive one day from one lender might be different a week later.
Finally, comparing quotes from many lenders is essential to ensuring that you're getting the best possible interest rate.
