The rules for real estate have changed. Here's how you can profit from the upheaval.

Austin Whitt has seen a lot in his six years as a real-estate agent. He weathered the pandemic in Tennessee, slinging homes in the Nashville area and training new Realtors as they piled into the industry. But twice in the past month, Whitt has encountered a rare sight: a buyer without an agent. In his years of listing homes for sale, Whitt had come across this kind of rugged individualist only once before. Sure, the recent run-ins may have been a coincidence, a blip. But given the seismic changes underway in real estate, Whitt can't be certain.
