About this rule
How to tell
Achhe (is there) means is there right now. For living or staying somewhere as a habit, and for will be there, use thaka (to live, to stay):
Why it works
Achhe (is there) has no future and no habit form, so thaka (to stay) fills in.
Its present means live or stay: Ami London-e thaki (I live in London)
Its future is the usual way to say will be somewhere.
Good to know
For will be with a description, use hobe (will be) from howa (to be): Kal gorom hobe (it'll be hot tomorrow).
