Is there ever an acceptable time to not give at least 15 days advance notice of the change in servicer? I do not believe there is, but our mortgage lenders are insisting that they should provide the notice at funding, rather than closing, which sometimes does not provide 15 days notice. I don't know where they came up with the idea that providing it after the loan has been funded by the investor is the way to do it. One argument has been that until the investor funds the purchase, too many things can go wrong and it might not go with that investor - in the which case the Notice of Transfer would be incorrect.
