It all depends on what the changes to the contract are, if it triggers a new assignment or not. If the changes are price changes or sellers concessions changes, it is not a new assignment because we are appraising the real estate, not the contract. We can keep the same effective date, just change your signature date and explain the differences between your two reports. However, it would be considered a new assignment if the contract changes actually change the real estate you are appraising, such as when we are appraising new construction and the changes are options added or delete, repair changes, FHA to Conventional loan changes or vice versa, etc. The bottom line, if the contract changes change the actual real estate, then it triggers a new assignment, but if the changes are independent of the real estate you have appraised, then it is not a new assignment and can be handled with the signature date change and proper explanations of what the differences are between your two reports.
