Once you have the contract with seller, how do you assign the contract to the end buyer? What forms should be used?
A good title company should have the form you need. Be aware that some title companies have no idea what a contract assignment is, while there are others that do them all the time.
Some may also tell you that it’s illegal or it can’t be done. Believe me I’ve done several with my title companies help and never had any issues. They can also make out the check to who ever you tell them to.
