Do you have PR? A merchandise store? TV & Radio? A lot of factors that would help boost your income, but the most would be to promote. Another way to boost revenue would be training players that can either help you promote or that you can sell. It doesn’t appear you’re training anyone of note, nor have you done so previously from your transfer history. If you’d like any tips or help, either myself(or someone you may dislike less) would be happy to help at the Discord channel linked in my signature.
As to making intelligent inquiries, what you can’t find from my team history are the number of U21 players(or others in general) I’ve trained, the fact that this is my second full stint in BB(first ended in a fun fashion, just find Shrewsbury Honeybadgers in the forums), or the fact that my time in Div IV was spent training while running an U21, as well as finishing my arena so that I would not need to do so later on.
I once had a team with 1757 players and was $25,835,360 in debt. This is not that team. Join the Discord group open to anyone, but especially for USA managers to improve your club or get involved with the U21 and NT programs
