Simple. If there is a new assignment number, it is a new assignment. A new assignment, if one follows the guidance of the AO's does not necessarily mean that one must start all over. It usually conveys the message that there will be a new assignment date, perhaps a new date of inspection, and certainly the date of the report would change.
I don't see it as simple as you do. :new_smile-l:
Refer to FAQ#159, which deals with changing the SOW after the report has been submitted.
In the OP's case, we have:
A. The same client.
B. The same inspection, valuation analysis, and reporting requirements.
C. The same intended use and users (mortgage finance decision, the client and HUD can rely upon the report.
D. The same borrower and the same property.
The client wants a loan or FHA case number changed. The case number issue is FHA-specific, so if that cannot be changed per them, that's an FHA issue (IMO); and only by extension does it become a USPAP issue.
Why does changing a loan number, when no development fundamentals change, become a new assignment?
I'd say if one can change the SOW after the report is submitted (which is very significant, IMO), I don't see why a loan number cannot be changed.
If reporting the loan number is an "assignment condition", then the SOWR allows for modifications to the assignment conditions as long as results are credible given the intended use.
Obviously (for reasons I don't understand) the OP's regulator sees it different. And you (Don) see it different. I don't see the part where it says an appraiser cannot change the loan number without creating a new assignment. In fact, I see, in cases where the client and intended use do not change, a lot of other things can change without creating a new assignment.
If I were in the OP's situation now, I'd call my regulator and ask them. If they told me it is a new assignment, then I'd follow their advice. But I'd ask them where in the USPAP are they reading that so I could understand how they came to that conclusion.
