I started focusing on real estate photography this year and your site has been a very valuable resource! When I Googled this subject, I saw that some people referring to Google Earth Pro users being able to use images commercially, but sifting through the opinions on the online world to get to the facts is the key.
Yes, if you look at the permissions guidelines for Google Maps and Google Earth, they just don't want you to remove the attribution on the images. Specifically, they say, "All uses of the content must provide attribution to both Google and our data providers. We require clear, visible attribution when the content is shown..."
Using Google Earth fly-ins used to be a popular intro on a property video. However, many of the top Realtors who used Google Earth fly-ins and the top real estate videographers have changed to drone intro footage and if done well, it comes off much more elegant and realistic.
