Do you really need a mortgage broker? I have used brokers in the past but they were usually for projects that had a risk factor. For personal use I just go to my bank where I have a credit history.
I think if I were starting fresh at this point, I would get a copy of my credit report, make a list of my assets and liabilities, dust off my last couple of tax returns and make up an email package.
I would then go online and compare mortgage rates of financial institutions and rate them on their products. I would then call up local branches, have a short conversation with the mortgage officer there and get their email address.
Now you are dealing with the person(s) that will lend you the money and you have the opportunity to ask questions and compare products. You will most likely find that there are a lot of more options out there than you thought.
