area where it concerns overhead due to law seems does seem ripe for disruption. But my concern is that this isn't a technical challenge, but rather political/legal one.
I mean that the buying/selling process is rather backward in technology and there's a lot of misunderstanding. The difficulties are less political and more inertial.
A primarily digital brokerage would be (is) a huge improvement.
If you want an industry ripe for disruption, consumer real estate is HUGE. Got a couple start ups in my area trying to do that.
