Yep. It is pretty damn hard to defraud a lender by over valuing the collateral unless the lender is a total idiot.That is 100% correct. Same thing with Trump, it's the lender's call to assure the value before handing over their money. Trump can tell them any value, it's up to them to underwrite the equity.
There was one case long ago in Amarillo TX. Our friend was in the finance business and they made mostly small personal loans on cars, furniture, other collateral of that type. It was a stormy day with wind driven rain and a severe thunderstorm warning when a customer comes in requesting a $1,000 loan against his car. He had the pink slip, tag number, serial number in hand. He said it was visible outside the window and sure enough when they opened the blinds and looked they saw a nice looking car--can't remember the make--that certainly was worth more than $1,000. The guys credit was okay so they made the loan, handed over the $1,000 and the guy left. The next morning the car was still there which seemed odd so they went out to inspect it. The side they couldn't see had massive collision damage and there was no engine under the hood. The guy or somebody had pushed it into the parking place and gambled that the lender would not go out in the rain to inspect it.
You can be sure that company made no more loans without doing the proper inspection. And banks and other mortgage lenders don't make loans without appraisals.
