This might be good info to give to the property. I've seen some property pages that give the actual GPS coordinates in their directions section. Really helps for older systems that might not have the new address. But then also a good chance it doesn't have the street(s) either if a new development.

My onboard Nav system has data as of 2007 so not up to date at all. I still use it to get a quick glimpse of where I am at (sound muted) and I use Waze to get current info and traffic updates! Granted geographically limited at times, but works fine for car trips.
