If a non-seller transaction is submitted on the “Model†form, the GSE collection systems will issue warning messages at the outset of the mandate and will not prevent a submission from being considered “successful.†However, the warnings may be changed to a hard stop at a later date. More information will be provided by the GSE regarding the timeframe for these hard stops.
