First, you should come to terms on what it is that you are looking for in service (i.e., Personality, process, etc.) Interest rates change. Credit scores have an impact on what loan programs you are qualified for. Mortgage brokers can be brash or they could be well-educated or they simply view each borrower as a number and "next" if you are not interested.
I have originated loans and I find that the way I do loans is very different from my colleagues. Their way works for them but not for me. My way works for me and not for them. I am very detailed; many people do not like details.
I call and I email my clients with face-to-face meetings when necessary.
I am present at the appraisal to meet the appraiser. I make calls to collection agencies. I call bankruptcy trustees and lawyers. I go to closings.
Real estate is different and the experience definitely depends on who you work with.
Does that make sense?
