Regulators have recommended such a rule and on August 12th a draft was issued for public comment. The link below will give you the details of the proposed rule. According to Fannie Mae, the primary intent of this proposed rule was not to have this apply to all Co-ops and Condos.
Their primary intent is to stop developers from imposing 99 year covenants on new homes that require seller's to kick back a percentage of the sale price of the home to the developer when the home is sold. They are currently reviewing the concerns of REBNY (Real Estate Board of New York) and hopefully, will revise language that would correct this serious problem.
If their response does not assure REBNY that he rules will be corrected, REBNY will ask it's members to join them in reaching out to the New York congressional delegation.
