What we do know is allegedly the buyer has requested not to be identified in Public. However, after the sale, the deed is Public Record and the Name of the Owner is available on Open Records. So if the Buyer is operating on the idea that non disclosure of their name at this point is some how providing anonymity, or privacy or security that would be an error.
Public record are just that, all you need is an Address, to find the name of the current owner.
Or a Name to find out how much and what property is owned in the County.
So the buyer may have made this request, it is an odd one.
Now, if that Person was qualifying for lets say a Teachers Home Grant, which would pay for a significant portion of the House, or any number of the Other Grants available for funding a house, they may not want this "Financial" information Disclosed. Who was the information desired, now how the Financing was being done. However, such grants are for the purpose of moving professionals into neighborhoods for the fact their being there is an improvement to the neighborhood. Thus, a teacher getting a grant, should be not only an neighbor, but an asset to the neighbors and community as an educator. Well, that was the intent of these grants.
However, the cageyness of this City Council and Redevelopment Agency, and their past actions require public attention, to all aspects of a transaction at this point. There is no Private Business when you are doing business with a PUBLIC Entity. This is the only protection the Public has against corruption, and conflict of interest and miss management.
