Obviously you'll need to apply. A type of company you left and it was credit unions. My Credit Union to mortgages has loans prosessors and closers. Check Credit Unions in your area. I know a lot about my credit union because I retired from there. If you are in Northern VA or DC area, e-mail me and I will give you info on that credit union and others in the area.
