This shouldn't be down voted, this type of arbitrage is common and the parties engaging in it know the baked in risks. It is no different from the common gambit of buying land outside of cities zoned as industrial or agricultural and then waging politics to have it rezoned as residential to dramatically increase its value.
Yes and no. If someone buy land at scale , and tries waging zoning politics...yeah, okay, arbitrage. Vs. if John Doe buys a house near a substantial airport, then claims he didn't know? No, sorry, nothing's gonna change in his favor. Maybe he imagined it would, and planned...but that's just the difference between ignoramus and fool.

My landlord did something like that with a few buildings for the big London sewer project. London actually paid him for new windows and things like that.
You just apply the force. Most taxpayers don’t notice this stuff so you can get hundreds of thousands out of it.
Many government projects are slow, too, so you can do this for ones where they’re announced but no work has been done. Bam, free upgrades, earthquake retrofit, etc.
