One might get a nice vacation house for cheap.
One of such houses (not those shown in the video) was actually near the places where I grew up. Such place is nowadays decently connected (still sub-optimal, but decent). If somebody was forward-looking enough could have bought property for extremely cheap and would be working from there now.
In my opinion, one of the big factors in evaluating a house is the nearby infrastructure, mainly connectivity and railroads / public transport in general. You'll need those anyway. If they're either not present or subpar then you should value the property less imho.
Edit: decently connected means a fttc (fiber to the cabinet, copper on last mile) connection, max speeds being 1gbps down / 100 mbps up, for 25-35 €/month -- you'll never reach such speeds of course, but even one tenth of that would still be usable for most things.
