Should I choose the lender with the lowest interest rate and costs?

There are two important things to consider when choosing one lender over another one:

Quality of Service – Especially for first-time homebuyers who will have many questions about the total financing process and available loan options. Finding a lender with outstanding service skills that you trust will comfortably guide you every step of the way, so ask questions, even before you fill-out an application.
Cost of Services – It’s good to ask potential lenders upfront what they charge for their services and any fees involved. They should be able to give you facts and get you through the financing process so that you feel confident knowing that you made a good decision by choosing them.
