First, you don't have to redisclose a revised GFE for a GFE originally given in 2009.
Second, if you chose to, follow the response HUD gave above:
In the case presented this is a borrower requested change which constitutes a change circumstance. You would issue a revise GFE using the old form since the original inception date of the application and disclosure was in 2009 and you did not originally disclose using the new GFE.
Your investor is requiring a new GFE meaning a revised one, correct? But they're not dictating the GFE form (old or new) to use, right? If they say you have to use the new form, copy and paste the HUD response here and send it to them. My experience is when faced with a properly documented response, the investor will back down.
