Huh WHERE IS THE MONEY? LS19?

I'm currently playing the game Farming Simulator 19 for the ps4. But funny way I suddenly get money out of nowhere? Where does that come from? I had 700 thousand before then I slept Then suddenly I had 2 million and then again 3 million without which I sell or something! Where does the money come from? Please LOOK AT VIDEO WHERE YOU CAN SEE IF I'M SLEEPING THAT I HAVE TO GET 3 MILLION FOR BUILDING REVENUE.

Apparently you rent something or something but when I see these numbers already seems to me the game generally quite far from reality.

Man, I think I can't rent things
