The "buyer" takes the money (1.5mil) from the bank through "borrowing";gives 100k to the appraiser, 700k to the seller . . . with 700k remaining (i.e. a $700k "cash-back," how's that? ). . . any wonder why the borrower misses the first payment? There was never any intention to repay.
"Cash-back" is the very definition of fraud in house transactions.
