Underground Shelter: Sell the Surface, Keep the Bunker
Here is a fresh concept in suburban stealth real estate: bury a prefabricated shelter in your lot, then market the surface land to a housing developer. The unsuspecting family above you gets a normal house, while you keep the hardened hideaway underneath. It's an unconventional defense plan, if your risk scenario involves both economic collapse and roaming political marauders who might be tricked by the decoy home on top. Functionally, you've placed your safe room in the one spot no enemy will ever think to look: right under a neighbor's floor.
