Re: the transaction coordinator fee, I just got a reimbursement check for this very fee from a legal company that specializes in class action lawsuits.
The RE company was Coldwell Banker. Everyone who closed escrow with them during a certain time frame (I believe it was two years) got a $200 refund check, whether the fee was part of their escrow paperwork or not.
I agree with the OP that such fees should be part of the Realtor’s commission and not an add-on.
