Flipping can sometimes also be a criminal scheme. Illegal property flipping is a fraud whereby recently acquired property is resold for a considerable profit with an artificially inflated value. The property is quickly resold after making few, or only cosmetic, improvements. Illegal property flipping often involves collusion between a real estate appraiser, a mortgage originator and a closing agent. The cooperation of a real estate appraiser is necessary to get a false, artificially inflated, appraisal report. The buyer may or may not be aware of the situation. This type of fraud is one of the most costly for lenders.
