text: The more info you have the better.  If you use a mortgage broker they are going to search their base of investors, whether they are using big money like Washington mutual or some other lending sources or private money.  You don't want to have every mortgage broker run your credit because the more hits you get asking for your rating the more your rating can be affected. The best thing to do is check your rating yourself and then present your info to the broker and ask him to give you a good faith estimate.  There are many things to watch for when doing these transactions so do your homework and take no shortcuts.  The lender, whether it be the bank or investors, is going to look at 1.  Your income, through check stubs with year to date info\n2.  Your credit rating, 680 or higher is pretty good\n3.  Your current profession and how long you've been in it, or on the current job.\nAnd maybe some other things also.  I just got done with a loan package so somethings are still fresh in my memory.  Make sure you get the info from a broker or a banker and then study the papers ask questions and don't go to every mortgage broker in town having them run your credit. There is a website for someone I know you might email him and get some answers,Good Luck!!!!!
