I agree with eightbore on the tax comments.
This is an inheritance and ,as far as I know, not subject to taxes.
It would seem to me that instead of taxes to be paid, a deduction might be made on a return for the fees paid in selling.
Check with your tax accountant.
I also agree with DaveK on whom to think of as an agent. Go with the big dogs when dealing with the big dogs.
Best,
