There's just so much fundamentally important info about REI that most data don't convey (Zillow discovered this the hard way, when they tried and failed to invest in real estate based largely on data inputs, rather than boots-on-the-ground knowledge).Real estate is literally a physical item, with physical functions, governed by physical realities, and because of that, it can only be fully understood through physical means (seeing properties with your own eyes, experiencing neighborhoods in person, meeting potential tenants face-to-face...or at least on Zoom).

It’s about understating the fundamentals of an asset which will drive value in the future.
