Many insurance companies won't appoint you 1) because you haven't written any business with them or 2) your financials - either owing insurance company monies or bankruptcy
#1 makes no sense. Until I was appointed, I had not written any business with any of those carriers. With some I was appointed and still didn't write any business. Others terminated me later because I wrote so little business.
#2 very few companies I have encountered will refuse to appoint you because of your financial history. Illinois Mutual is one that comes to mind. They turned me down a few years ago when I was struggling to rebuild my financial life.
Most of the time you can get appointed, but you may not be eligible for commission advances.
As long as you are not in trouble with the DOI, criminal justice system, or IRS you should be good to go.
