Like others, I've been using it but it seems like a waste. I don't know the source of the info nor do I have access to the source to put it in my work file. So for every appraisal that I do, I still need to look up city data, county data, tax record and anything else so I can make a copy of the source document for my work file. The 20 seconds of typing I save does not seem worth it. I would never pay for the service.
For me it begs the question, what do we need to keep in our workfile? If others are using all of these auto populated data sources without verifying, am I putting myself at a competitive disadvantage by going to each source individually and documenting the source? I'm sure I am. I'm sure many appraisers just take the data and run with it. But I feel it is my obligation to go directly to the source and document the data in my workfile.
Until USPAP and all the government instituions declare that data coming from major data providers can be considered as a verified source, and the appraiser is not liable to verify the data, I believe we are all obligated to verify the information. Even if it was considered a verified source, I might question some of if. But I might use it if the source met my legal obligations and I felt it was ethical to rely on the data. But until such a statement is made, I will be verifying my data. So the public records info provided by CoreLogic is really worthless.
