As an additional benefit, since any fridge or freezer generates waste heat on its 'warm' side (the room itself), the additional heat from the freezer will rise from the basement into the rest of the house. As compared to if you had a freezer on the 3rd floor of a tall/narrow town house, all that the heat would do is rise towards the ceiling and attic.

I would not advocate for moving a fridge to the basement just because of the hassle and back and forth trips involved. But if I had a dedicated top-opening chest freezer, sure.
