I have the same problem with the LM’s. I have given up on several deals and told they to take the property and shove it. It is hard to tell if they are lazy or stupid or both or just have no decision making power or just perhaps too busy. I have gotten the no response no care attitude over and over again. I finally got an answer from one of them and it was a no. I always ask for a superior to call me and they never call either. Once they did call and just referred me back to the same person.
I see no reason you can not sell the contract unless the contract forbids it.
