Ours have a hole about 50mm in diameter. It’s not going to bring your wall down and if you decide that you don’t need the efficient heating/cooling with minisplit-unit it’s easy enough to patch. I own the house, so I didn’t need to think nothing else than the location of the hole, but any sensible landlord would see a minisplit-unit as an increase of property value.
