My Real Estate Team currently has a 28 acre new development listed. We've had the listing for 6 months and have spent thousands of dollars advertising/promotions etc. The sellers have continued to demand duties and we just found out they have been working with buyers on some of the building lots but don't want to pay commission to us. They've also asked for a release of all listings. We are only assuming so they can now go and sell to the buyers they have been keeping quiet about. Can't we request a monetary amount for all the expenses that we've spent thus far since they are clearly breaking the listing agreement?
