The ongoing maintenance for food and water is pretty low:
For food, when I open containers of non-perishables I take them from the front of the line, and when I buy new ones I put them at the back of the line.
For water, 14gal/person is two 1ft^3 water containers. I’ve set a recurring reminder to swap the water out every five years.
An additional cost is the hassle of moving/selling/giving away your stockpile if you move.
For water you can just dump it out and refill at your new place. For food it’s pretty small compared to the rest of what you’re moving, maybe two ~1ft^3 boxes per person?
