We are now authorized to charge late fees without needing to get approval. This is from the Dec 1, 2021 fee update guide:
Payments - Lenders and other appraisal requestors should note that VA Form 26-1805,
VA Request for Determination of Reasonable Value (Real Estate), states “On receipt of
‘Notice of Value’ or upon advice from the Department of Veterans Affairs that a ‘Notice of
Value’ will not be issued, we agree to forward to the appraiser the approved fee which
we are holding for this purpose.” If a payment has not been made within 30 days of
billing, a late fee charge not to exceed state usury statutes is authorized. Late fees
cannot be charged to the Veteran. Lender Appraisal Processing Program lenders are
responsible for their approved agents.
If I had a Lender that wasn't paying, I would be adding late fees, it just might get their attention.
