Why is goodman only bothering marvin and not braxton

So we know that Marvin owes house payment to Goodman, but we also know that Braxton owns the house So why hasn't goodman met Braxton or even question how could marvin even afford a private chef because we see in day in and day out, goodman comes to the house meet chef pee pee and doesn't say a thing, or the fact Marvin being so stupid, he hasn't even really remember the fact that he doesn't own the house. He lives there with braxton and his son and private chef So why hasn't he told goodman off yet
