Can the government retain all foreclosure proceeds?

The Supremes, AKA the Justices of the United States Supreme Court, are going to weigh in on foreclosure sales. Specifically whether when the government retains a surplus from a foreclosure sale, is that a violation of the Takings Clause? And, whether low sales prices at a foreclosure sale violate the 8th amendment prohibition against excessive fines. Pung v. Isabella County, Michigan.
