Fannie Mae / The Federal National Mortgage Association [FNMA] review: 'Non disclosure' regarding property. 1

We recently purchased a foreclosed home from Fannie Mae. There were obvious
issues with the property that were discovered during walk through & inspection process.
For example the copper pipes were removed from the property subsequently a thorough plumbing test could not be completed.
Seven days after the close and the renovation phase began it’s been determined the well system was disassembled and no longer operable. It was also clear the home was winterized approximately 6 months prior when the plumbing was removed and well disassembled.
Clearly the Fannie Mae should have disclosed this in the property details so perspective Buyers could make an informed decision regarding the property. Non-disclosure of issues is illegal.
