Technically? Sure. You could also look into having water delivered.

Would something
like that be as simple as adding the tank and running a pipe over to it
from the well, then adding a pump in the tank for the house? (or are
there a bunch of inspections and permits that would be required for
something like this?)

Inspections and permits would be required in most locations, especially if a
mortgage on the property is involved. But that brings up a potential issue you
may not have considered. Getting a mortgage on such a property will be difficult
to impossible.

If you are able to purchase for cash or finance privately, you also need to
consider the salability of the property in the future, which is likely to be
very difficult.
