Before we bought a house (in SF) we rented. My landlord was born in SF and owned his own home in Daly City. He inherited the house from his mom for free with a 200k tax base on a 1.1m home. He owned a food truck that was grandfathered by SF - sometime in the 70s he parked on city property (the government area) and ended up squatting there so long the city let him stay. His closest competitors were two blocks away. You'd think that business would have premium value - no one can get a permit or permission to setup a similar business in that area and anyone working in the area had to walk several blocks to find competition. He parked the truck in his mom's garage in SF until we rented the house (free enclosed parking, with charging, water tap and drainage!) Instead he retired and shut it down because no one would make enough money operating the business to want to take it over. Driving your food truck 2 hours every day was just not enticing and most people wouldn't be able to find a safe place to park the truck with electrical and water access. The only people capable of operating that business were old people who bought their property cheap in the 60s/70s or children who inherited property for free. It isn't always that no one wants the business... sometimes the personal economics make it impractical.
