This conversation is going in all direction mainly because only two of us in the conversation have experience, though limited, with the software.
1. This is not a substitute for the 1004 or 1004MC. Please be clear about that fact.
2. Once the regression is done, than as with any other appraisal, let say a drive-by, you pick comps as you always do.
3. This is not a service to replace 1004; but, lenders and broker are turning to BPOs and AVM's like Zillow and taking money from our pockets. This service and software is directed toward that market. For a purchase the 1004, 55, 73 and all the rest will still be required.
I am just saying gentlemen, see the program/service for what it is, no more no less.
