Artificially increasing an undeveloped land parcel’s book value far over its fair market value . Fraudulent, illegal practice. Colluding buyers typically buy and sell the same property several times among its members. Each time the price increases. The group then sells the property, or get a loan to develop it, at an unrealistically high price. This robs its buyers or lenders of large sums when the property’s value sinks back to its true market value.
