Here I am now wondering why 3 well know companies are resorting to this kind of activity as I know it is a scam but the way it is being conducted the 3 involved can't be connected.
I guess this is a heads up on a new approach to get money from you.
I have to wonder if the bogus appraisal service is a 2 or 3 way scam: 1) They get your fee for "their appraisal service", which is worthless, because, 2) the purported buyer never actually intended to buy, and, 3) since they're already running a scam why not take it one step further and sell your credit card information.

The best thing to do is to just ignore those emails.
