There are some distinct limitations on what happens when such deals are reported to the authorities. There are only so many resources available, and most of the agencies aren’t going to chase a single deal unless they’re provided with some or most of the evidence that demonstrates a criminal act.
In other words, unless we had a (substandard) appraisal in hand or some other document that would serve as evidence the reality is that most of the law enforcement agencies aren’t going to use their resources to chase the case.
