Foreclosure sold to Kondaur Capital - lets make a deal questions

[John C.]

The house is in Michigan, Wayne County.
So the company below, Kondaur Capital Corp., bought my mortgage at the foreclosure sale. They called me and wanted to work with me to get the house sooner than waiting for the redemption period to end. They said "In exchange for your cooperation we would not to submit any foreclosure information to the 3 major credit reporting bureaus. We will not pursue you legally concerning any deficiencies that may exist concerning the above mentioned property."

1) Am I mistaken but doesn't the original mortgage holder control if there will be a foreclosure on my credit report?
2) Also doesn't the original mortgage holder decide on the deficiency?
3) Anyone familiar with this company? Do they do what they say they will do?
4) Can I sell them my redemption right and if so how much? If I wait I am getting the rent money right now.
5) What terms should I ask for?
