If I'm refinancing my home mortgage and and my new lender is also paying of 3 other loans including my commercial loan, is my new lender required to disclose to me the information they received back on the demand statements they sent to the other lenders, especially if there are prepayment penalties involved with paying off my commercial loan.

Yes, you must be informed of the payoff amount.  This will effect your cash needed to close or cash out depending on what you are doing with the refinance.

The answer is yes, they should provide them.  Have you asked them and they refused?
