There was no victim. The banks / bank officials testified as much. The loans were between private individuals. The government wasn't involved.
Who was the victim and how much did they lose?
$18,990 and change. Trump didn't take anything from anyone. Private banks made a deal to loan him money at a specified set of terms. The government wasn't involved. The banks said the loans were paid in full.
In Jame's case, she was getting government backed mortgages and by lying on the forms she got better terms and bilked the government out of interest and fees they charged others for the sort of loan she should have gotten. Further, the forms said lying on them could result in criminal charges.
So, how much of a loss is small enough that it doesn't matter, $18,990? How about $10,000? $5,000?
