There are usually a lot of attorneys and title companies involved in wholesaling....I don't think all those professionals would risk their credentials if what they were participating in was illegal.Like everyone said, look up your local laws as they are different in all 50 states but as long as you are following the language in the contract the seller has signed you should be fine.If it says don't market, don't market, if it says no assignment, don't assign...if that's the case, get a new contract.
