Your idea, as well-considered as it may have been, is a complicated workaround to the problem that Silicon Valley money does not want to leave Silicon Valley, and is thereby causing an explosion of inflation, driven by too much money chasing after too little common sense.
In the rest of the country, this is called a "trailer park" or "RV campground". There is no second, remote property in Nevada, because all the homes adhere to a common standard for utility hookups and foundation pads. Even so, despite the theoretical possibility, most mobile homes do not actually move more than once. This is because it is several orders of magnitude easier to move people and their personal possessions than the buildings they live in, even when such buildings are designed to be moved.
I don't want to be mean about this, because you did put your idea out there and stand behind it, but it is not an ideal business plan. There is already a solution to the problem wherein a businessperson needs to be in a certain city for 10% of the year, while still enjoying most of the amenities of home--several, actually: hotels, time-share condominiums, furnished apartments rented weekly, couch-surfing, pieds-a-terre. There are also existing solutions for portable homes: touring buses, RVs, camper trailers.
