If you talk to a loan officer, he (or she) will probably say the lender they work for is "the best" and give you a list of reasons why. If you meet the same loan officer years later and he works for a different kind of lender, he will give you a list of reasons why that type of lender is better.
Realtors have differing opinions and, as a group, their opinions have changed over time. In the past, most would often recommend portfolio lenders - because they almost always closed the deal. As time passed, mortgage bankers and mortgage brokers became more important, and agents switched along with the changing times.
Most often a Realtor will direct you to a specific loan officer who has demonstrated a track record of service and reliability -- or a loan officer who works for a lender affiliated with their real estate office.
